Genuinely lovely to write in, honest about not training on your work, and priced in US dollars with nothing Australian about it. - Author: Adam - Tags: Writing & Content AI, Lex, #review **16**/25 ★★★★☆ Very Good Lex, Inc Verified 1 Sep 2026 Pricing checked 21 Sep 2026 Value for Money**3**/5 Ease of Use**4**/5 Feature Depth**4**/5 Australian Fit**2**/5 Reliability & Support**3**/5 From **A$21**/mo · ex-GST · billed in USD **The gate:** Five stars need 21+ and Australian Fit of at least 4/5. [Skip to the verdict ](#verdict) *Pricing figures updated 6 September 2026: USD prices are converted at the current rate (1 USD ≈ 1.40 AUD, verified 5 September 2026) and shown ex-GST, replacing the retired 1.55 + GST basis. A GST-registered Australian business that supplies its ABN is not charged GST on an imported digital service; other buyers should allow \~10% on top (*[*Methodology*](https://www.theaidirectory.com.au/methodology/)*).* > **The verdict:** Lex is the rare AI writing tool built for people who actually like writing. It is a clean, Google-Docs-style word processor with AI woven into the editing process — you type `++` and a command, or ask it to critique what you have written, and it responds inside the document instead of in a separate chatbot window. The philosophy is the draw: Lex positions the AI as your editor, not your ghostwriter, and it states plainly that your writing is never used to train models. For an Australian professional who drafts reports, proposals and client emails, that combination — a serious drafting surface plus a second pair of eyes — is genuinely useful. The catch is the usual one, plus one of Lex's own making. There is no AUD pricing, no Australian data-residency story and no local support, and Lex does not even publish its prices on its public pricing page — you learn the cost (US$24.99/month, or US$179.88/year) at checkout or from its newsletter. It is a small, seed-funded company with email-only support, and parts of its public site are visibly out of date. Lovely tool, thin edges. Score: 16/25 — Very Good. ## What it is Lex is **a collaborative document editor with AI built into its core** — a browser-based word processor (with a desktop app, and an iOS app in early access for Pro subscribers) that looks like a stripped-back Google Docs and behaves like one with an editor reading over your shoulder. It comes from **Lex, Inc.**, a San Francisco-registered startup founded by **Nathan Baschez**, who built it inside the media company Every before [spinning it out in 2023](https://every.to/on-every/we-re-spinning-out-lex-2a5c49ea-5436-4261-ba7b-dbc8aa0c89c2?ref=theaidirectory.com.au) and raising a [US$2.75 million seed round led by True Ventures](https://techcrunch.com/2023/08/23/lex-ai-writing-tool-seed-round/?ref=theaidirectory.com.au). Lex says [more than 300,000 writers](https://lex.page/?ref=theaidirectory.com.au) use it. The design bet is what separates it from the pack. Most AI writing tools are generators — you brief them, they produce copy, you clean it up. Lex inverts that. You write the draft; the AI brainstorms with you, flags problems, suggests rewrites and answers questions about your own text. Three mechanics carry the idea: - **Inline `++` commands.** Type `++` anywhere in the document followed by a plain-English instruction — continue this paragraph, shorten this, rewrite this more formally — and the model responds in place, in your document, without a context switch. - **AI feedback and checks.** Ask Lex to critique the draft — structure, clarity, flow — and it comments on what you wrote rather than replacing it. This is the feature the whole product is organised around. - **Ask Lex chat with context.** A chat that can see your document, plus **context tags**, **personas**, **style guides** and **knowledge bases** you set up so the AI knows your voice and your background material — features Lex rolled out through its [V2 releases in 2025](https://buttondown.com/lex/archive/?ref=theaidirectory.com.au). Around the AI sit the ordinary word-processor essentials: live collaboration, comments, version history, folders, and publishing a document to a read-only link. Track changes was listed as "coming soon" at review time ([Lex homepage](https://lex.page/?ref=theaidirectory.com.au)). ## What it costs in Australia Here is the first oddity: **Lex does not publish its prices on its public pricing page.** The [pricing page](https://lex.page/pricing?ref=theaidirectory.com.au) describes what Lex Pro includes and answers FAQs, but carries no dollar figure — you see the number at checkout, inside the app, or in Lex's own emails. For a paid product in 2026, that is a transparency miss, and we are marking it as one. The actual prices, from [Lex's own price-change announcement](https://buttondown.com/lex/archive/lex-upcoming-price-increase-lock-in-rates-before/?ref=theaidirectory.com.au) (effective 18 July 2025 and current at review time): | Plan | USD | Approx AUD (\~1.40, ex-GST) | What you get | | ----------------- | -------------------------- | --------------------------- | ----------------------------------------------------------------------------------------------------------------------------- | | Free | $0 | $0 | The editor, sharing and collaboration, basic AI on smaller models | | Lex Pro (monthly) | US$24.99/mo | \~A$35/mo | Premium models (GPT-5, GPT-4.1, Claude 4 Opus and Sonnet named by Lex), early feature access, iOS app, priority email support | | Lex Pro (annual) | US$179.88/yr (US$14.99/mo) | \~A$252/yr (\~A$21/mo) | Same as monthly, \~40% cheaper | | Lex Teams | Not published | — | Add-on for unlimited group use of shared folders | Australian notes. Pricing is **US dollars only** — no native AUD price exists, so the AUD figures above are our conversions at roughly 1.40 and will move with the exchange rate. **Lex publishes nothing about GST treatment**; payments run through Stripe ([privacy policy](https://lex.page/privacy?ref=theaidirectory.com.au)), so check your checkout total and your invoice before assuming the GST line either way. The free plan is real — the editor and collaboration cost nothing, and Lex's own FAQ confirms free users get AI on lesser models — but **Lex does not publish the free tier's AI usage limits** anywhere on its site, and third-party figures conflict, so we will not quote one. Lex offers a first-month [refund on request](https://lex.page/pricing?ref=theaidirectory.com.au), and says you can ask for a free trial of Pro by email. At \~A$35 a month paid monthly, Lex costs more than [Grammarly](https://www.theaidirectory.com.au/grammarly-review-australia-2026/)'s Pro plan and sits in the same territory as a ChatGPT or Claude subscription. The annual price is the sensible way in. ## How it works / features You write in a clean page that will feel instantly familiar to anyone who has used Google Docs, minus most of the toolbar. The AI is summoned, not ambient: - **`++` commands in the flow of writing.** The signature move. Brainstorm a section, continue a paragraph, tighten a sentence — inline, without leaving the document. - **Document-aware chat.** Ask Lex questions about your draft — "is the argument in section two convincing?" — and get answers grounded in what you actually wrote. - **Personas, style guides and knowledge bases.** Teach it your voice and feed it your background material once, and it applies both across documents. For a business writing recurring proposals in a house style, this is the quietly powerful bit ([Lex V2 announcements](https://buttondown.com/lex/archive/?ref=theaidirectory.com.au)). - **Model choice on Pro.** Lex brokers the frontier models for you — its pricing page names [GPT-4.1 and Claude 4 Opus and Sonnet](https://lex.page/pricing?ref=theaidirectory.com.au), and its newsletter announced [GPT-5 live in Lex Pro](https://buttondown.com/lex/archive/?ref=theaidirectory.com.au) in August 2025\. Lex's pitch: pay one subscription and it plugs in whatever is currently best for writing. - **Real collaboration.** Live cursors, comments, version history, shared folders, read-only publishing. It can genuinely stand in for Google Docs for drafting work. One caution on the model list: parts of Lex's public site are stale. The same pricing page that names Claude 4 models also still calls Claude 3.5 Sonnet the best writing model — copy that was true in 2024\. The product ships current models faster than the website records them, but a vendor page you cannot fully trust for currency is worth knowing about. ## What it does well **It is the best-feeling place to actually write with AI.** Grammarly bolts AI onto wherever you write; Jasper and [Sudowrite](https://www.theaidirectory.com.au/sudowrite-review-australia-2026/) generate; ChatGPT makes you copy-paste. Lex is a proper drafting surface where the AI critiques and assists inside the document. For a report or proposal you will redraft three times, the difference is not cosmetic — it is the workflow. **The no-training policy is explicit and unusually plain.** Lex states on its [pricing page](https://lex.page/pricing?ref=theaidirectory.com.au) that your writing is not used to train AI, that it accesses OpenAI, Anthropic and TogetherAI through their enterprise APIs specifically for the stronger privacy protections, and that "Lex is not training language models" — with a promise to notify and allow opt-out if that ever changes. For client-confidential business writing, that is a clearer statement than most rivals make. **One subscription, whichever model is best.** Lex swaps in frontier models as they ship — GPT-5 arrived within days of release. You get top-shelf writing models without managing multiple AI subscriptions or learning new interfaces. **The free tier is a genuine trial.** The editor and collaboration are free forever. You can move a real document through a real edit before paying anything. ## Where it falls short **Nothing about it is Australian.** USD-only pricing, no GST statement, no Australian data residency — the [privacy policy](https://lex.page/privacy?ref=theaidirectory.com.au) says data may be transferred, processed and stored "anywhere in the world," with hosting on AWS and no onshore option. No Australian entity, no local support. It is a global product Australians can use, not one built with Australia in mind. **You cannot see the price without digging.** No public dollar figure on the pricing page is a poor look for a tool asking A$39 a month, and it made this review harder than it should have been. Third-party sites fill the vacuum with conflicting, outdated numbers. **It is a small company with thin support.** Support is email only — hello@lex.page — with "priority" email for Pro. No published SLA, no status page we could find, no phone, nothing in an Australian timezone. Lex raised a US$2.75 million seed in 2023; it is a lean team, and pieces of its own website are out of date. None of that is disqualifying. All of it is single-vendor risk for a tool you would move your drafting workflow into. **It will not replace your whole stack.** Track changes was still "coming soon" at review time, Word compatibility is not the point, and if your organisation lives in Microsoft 365 with legal-hold and retention policies, a venture-backed web editor is a side tool, not a system of record. **Free-tier limits are opaque.** Lex confirms free users get lesser models but publishes no usage numbers. You find the ceiling by hitting it. ## Australian fit **Pricing:** US dollars only, no AUD, no published GST treatment — confirm at checkout. **Data residency:** none offered; Lex hosts on AWS and reserves the right to store data anywhere in the world, with document content passing to OpenAI, Anthropic and TogetherAI via enterprise APIs. The explicit no-training commitment is a real mitigation, but for Privacy Act-sensitive material there is still no onshore guarantee. **Support:** email only, US-based, nothing local. **Availability:** the bright spot — Lex is a web app with no regional locks, and Australians can sign up and use the free tier today. Australian Fit: 2/5. ## Score | Criterion | Score | Why | | --------------------- | --------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Value for Money | 3/5 | A real free tier and a fair annual price (\~A$252/yr) for frontier models — but \~A$35/month paid monthly, USD-only, and no published pricing on the public page. | | Ease of Use | 4/5 | Familiar Docs-style editor, ++ commands are instantly learnable, and the AI meets you inside the document instead of a separate window. | | Feature Depth | 4/5 | Inline AI, document-aware chat, personas, style guides, knowledge bases, real collaboration and model choice. Track changes still missing. | | Australian Fit | 2/5 | No AUD, no GST statement, no AU residency, no local support — but fully available here and honest about training. | | Reliability & Support | 3/5 | Explicit no-training policy and a money-back guarantee earn trust; email-only support, a stale public site and seed-stage vendor risk take it back. | | **Total** | **16/25** | | ⭐⭐⭐⭐ Very Good (16–20). Australian Fit is 2/5, below the 4/5 threshold in our [methodology](https://www.theaidirectory.com.au/methodology/), so Lex cannot be named a category Top Pick regardless of its score. ## Bottom line **If you write documents that matter — reports, proposals, submissions, long client emails — and you want AI as an editor rather than a ghostwriter, Lex is the most pleasant way to do it.** Start on the free plan with a real document. If the `++` workflow clicks, the annual Pro plan (\~A$252/yr) is the sensible buy; the monthly price is hard to justify against a ChatGPT subscription. **If you mainly need grammar and tone fixes inside the tools you already use,** [Grammarly](https://www.theaidirectory.com.au/grammarly-review-australia-2026/) (18/25) remains the safer pick — it goes where you write, and its business tiers have a proper data story. If you write fiction, [Sudowrite](https://www.theaidirectory.com.au/sudowrite-review-australia-2026/) (17/25) is built for that job in a way Lex is not, and if you only need sentence-level rewriting, [Wordtune](https://www.theaidirectory.com.au/wordtune-review-australia-2026/) (15/25) is cheaper. Our full field notes are in the [best AI writing tools roundup](https://www.theaidirectory.com.au/best-ai-writing-tools-australia-2026/). **If your work is Privacy Act-sensitive,** weigh the trade honestly: Lex's no-training commitment is better articulated than most, but your documents still live on US-controlled infrastructure with no Australian residency option. For confidential client material, that decision belongs to you, not to a subscription page. Update history - **21 Sep 2026** — **An Australian App Store listing exists, declares AUD, and sells nothing.** *Lex Writer* ([id6468129663](https://apps.apple.com/au/app/id6468129663?ref=theaidirectory.com.au)) is published by **Lex, Inc** (lex.page), and its listing declares `"priceCurrency":"AUD"` with **no in-app purchases at all**. Checked because the app-store pricing pass could not resolve it; resolved here by matching Apple's declared `sellerUrl` rather than the publisher name. A free companion app is a finding worth recording, not a gap: Confirms rather than disturbs this review: **Lex is bought on the web, and the web currency is the currency you pay.** Found by the app-store apply pass, `Audits/app-store-apply-2026-09-21.md`. Wayback: capture pending (archive.org saving unavailable 21 Sep 2026). - **1 Sep 2026** — First reviewed. ## Frequently asked questions ### What is Lex and how is it different from ChatGPT? Lex is a document editor with AI built in, not a chatbot. You write in a Google-Docs-style page and summon AI inline with `++` commands or ask it to critique your draft. ChatGPT generates text in a conversation you copy out; Lex keeps the AI inside your document, positioned as an editor rather than a ghostwriter. ### How much does Lex cost in Australia? The editor and collaboration are free. Lex Pro — which unlocks premium models such as GPT-5 and Claude 4 — costs US$24.99/month (\~A$35) or US$179.88/year (\~A$21/month at \~1.40). There is no AUD pricing, Lex does not publish these figures on its public pricing page, and it makes no statement about GST — check your checkout total. ### Does Lex train AI on my writing? No. Lex states that it does not train language models on user writing, and that it accesses OpenAI, Anthropic and TogetherAI through their enterprise APIs, which carry stronger privacy protections than consumer AI accounts. It promises to notify users and allow opt-out if that ever changes. ### Is my data stored in Australia? No. Lex publishes no Australian data-residency option. Its privacy policy says data may be transferred, processed and stored anywhere in the world, with hosting on AWS and document content passing to its AI providers to generate responses. ### Is there a free version of Lex? Yes, and it is genuinely usable — the full editor, sharing and collaboration cost nothing, with basic AI on smaller models. Lex does not publish the free tier's AI usage limits, so expect to discover the ceiling in use. Premium models require Pro, and Lex offers a refund in the first month if it does not stick. ## Read next - [Grammarly review: the incumbent writing assistant, tested for Australia](https://www.theaidirectory.com.au/grammarly-review-australia-2026/) - [Sudowrite review: the fiction-writing AI, tested for Australia](https://www.theaidirectory.com.au/sudowrite-review-australia-2026/) - [Wordtune review: the sentence-level rewriter, tested for Australia](https://www.theaidirectory.com.au/wordtune-review-australia-2026/) - [The best AI writing tools for Australians](https://www.theaidirectory.com.au/best-ai-writing-tools-australia-2026/) - [How we score AI tools — our review methodology](https://www.theaidirectory.com.au/methodology/) ## Sources - https://lex.page (primary; product description, features, 300,000-writer claim, track changes "coming soon") — Wayback: https://web.archive.org/web/20260902044447/https://lex.page/ - https://lex.page/pricing (primary; Pro benefits, named models GPT-4.1 / Claude 4 Opus & Sonnet, no-training statement, enterprise-API providers OpenAI/Anthropic/TogetherAI, Teams add-on, refund policy; page publishes no dollar figures) — Wayback: https://web.archive.org/web/20260902044614/https://lex.page/pricing - https://lex.page/privacy (primary; subprocessors OpenAI, Google, Stripe, AWS, Amplitude; worldwide data storage; Lex, Inc.) — Wayback: https://web.archive.org/web/20260902044631/https://lex.page/privacy - https://buttondown.com/lex/archive/lex-upcoming-price-increase-lock-in-rates-before/ (primary; Pro US$24.99/mo and US$179.88/yr effective 18 Jul 2025, prior US$18/US$144) — Wayback: https://web.archive.org/web/20260902044701/https://buttondown.com/lex/archive/lex-upcoming-price-increase-lock-in-rates-before/ - https://buttondown.com/lex/archive/ (primary; newsletter archive — GPT-5 live in Lex Pro (Aug 2025), V2 features: desktop app, knowledge bases & style guides, personas) — Wayback: https://web.archive.org/web/20260902044735/https://buttondown.com/lex/archive/ - https://every.to/on-every/we-re-spinning-out-lex-2a5c49ea-5436-4261-ba7b-dbc8aa0c89c2 (primary; spin-out from Every) — Wayback: https://web.archive.org/web/20260902044810/https://every.to/on-every/we-re-spinning-out-lex-2a5c49ea-5436-4261-ba7b-dbc8aa0c89c2 - https://techcrunch.com/2023/08/23/lex-ai-writing-tool-seed-round/ (secondary; US$2.75M seed led by True Ventures, Nathan Baschez founder) — Wayback: https://web.archive.org/web/20260902044838/https://techcrunch.com/2023/08/23/lex-ai-writing-tool-seed-round/ Exchange rate used: US$1 ≈ A$1.40\.
