Lex
Lex is an AI-assisted writing editor with in-document feedback, rewrites, and title ideas — closed to new signups as of 2026
The product idea holds up: AI critique, inline rewrites, and title generation living in the same document as your comments and version history beats tab-switching to a chatbot, and the enterprise-API privacy arrangement is a real differentiator against pasting a draft into a consumer AI account. But the homepage and pricing page both say Lex is no longer accepting new customers. That makes this an unactionable recommendation unless you already have an account. Existing users should keep writing. Everyone else should use Google Docs plus a separate AI subscription, or a Notion-style workspace with AI built in, and revisit Lex only if signups reopen.

Skip Lex if you are not already an account holder — the homepage says it is no longer accepting new customers, so you cannot sign up, try it, or price it today.
The free tier runs standard AI models with usage limits on Ask Lex messages, Checks, and custom prompts, so heavy AI use pushes you onto Pro at $15/mo.
On the published tiers Lex runs $0 free, $15/mo Pro, and $20/user/mo Teams. That undercuts a Notion workspace with AI add-ons and a separate ChatGPT Plus subscription stacked on Google Docs, and it matches roughly one premium AI subscription — you are paying for model access wrapped in a writing surface rather than for a database. Pricing is visible only to existing users after login.

What is Lex?
Lex — Lex is an AI-assisted writing editor with in-document feedback, rewrites, and title ideas — closed to new signups as of 2026.

Lex is a minimalist collaborative document editor built around the draft rather than a file tree. You write in a distraction-free editor, then call AI from inside the document to get feedback on tone and clarity, rewrite a selected passage, generate title ideas, brainstorm, or run command shortcuts to find the best word or build a list. Collaboration works the way most writers expect: share a link, log in with one click, and watch each other type. Read-only publishing links let you send finished work to someone without an account, comments are keyboard-navigable, and version history lets you try a different phrasing without losing what you had. The company says over 300,000 writers use it, and collaborators on phones work through mobile web with no app download. Privacy is the differentiator it pitches against pasting drafts into a chatbot: Lex hosts your data on its own database and reaches models from OpenAI, Anthropic, and TogetherAI through those vendors' enterprise APIs — the pricing FAQ says these protections are stronger for Lex as an enterprise customer than for you as a consumer, and states Lex is not training language models on your writing. The thing a buyer needs to know first: both the homepage and the pricing page now display 'Lex is no longer accepting new customers. Existing accounts will keep working as usual.' Pricing is visible only after login for existing users, and the FAQ is written for people already on an account. Lex is therefore not a tool you can evaluate by starting a free trial today.

Behind the verdict
Start with what Lex does well, because the craft is real. The editor is deliberately narrow: one draft, minimal chrome, and AI summoned from inside the text rather than from a sidebar or a separate tab. The specific moves are well chosen — ask for feedback on a draft's tone and clarity, rewrite a selected passage, generate a list of title ideas with one click, run command shortcuts mid-paragraph to find the right word or build a list. Comments are keyboard-navigable, version history lets you test a phrasing and roll back, and read-only publishing links mean a client or editor can read without an account. Mobile collaborators work through mobile web on a shared link with no app download. The second differentiator is privacy plumbing. Lex hosts your data on its own database and reaches models from OpenAI, Anthropic, and TogetherAI through those vendors' enterprise APIs. The pricing FAQ argues those protections are stronger for Lex as an enterprise customer than they are for you as a consumer, and states plainly that Lex is not training language models on your writing. If part of your hesitation about AI editing is where the draft actually goes, that argument is worth something. Where it gets hard is availability. The homepage and pricing page both carry the banner that Lex is no longer accepting new customers and that existing accounts keep working as usual. Pricing is behind a login for existing users, the FAQ asks 'what is the benefit of upgrading' — questions written for people inside the tent. So the honest frame is: this is a well-built writing surface in maintenance-and-existing-users mode, not a product you can sign up for and test this week. Second, scope. Lex is a writing surface, not a workspace. There are no tables, no page layout tools, no database views — if your work lives in Notion or Coda, Lex is an extra tab, not a replacement. Track changes is listed on the homepage as 'Coming soon', so if your edit workflow depends on suggestion mode today, plan around it. Third, the tier split. On the published tiers the free plan runs standard AI models with usage limits on Ask Lex messages, Checks, and custom prompts; the premium models named in the FAQ (GPT 4.1, Claude 4 Opus & Sonnet) sit behind Pro at $15/mo, along with early access to beta features, the iOS app, and priority email support. Teams at $20/user/mo adds unlimited shared folders and team management. Pro carries a stated refund if you don't love it after a month, and the FAQ invites existing users to reply and ask for a free trial — a channel that only exists if you already have an account. Who it fits: writers, bloggers, content marketers, students, and small editorial teams already on Lex who want one surface for drafting and editing and who prefer enterprise-API model access to a consumer chat account. Who it doesn't: new buyers with no route in, teams that need tables or footnotes, groups that require SSO, admin controls, or compliance tooling, and anyone whose workflow

GeneratedReal-world workflow fit
Concrete scenarios for the personas Lex actually fits — and what changes day-one when you adopt it.
You open a draft, ask the AI for feedback on tone and clarity, rewrite two paragraphs inline, pull a list of titles in one click, then send a read-only publishing link to an editor who has no account.
Outcome: A finished piece and an editor's comments live in the same document, with version history holding your earlier phrasings in case you want them back.
You share a link with a co-author, both log in with one click, and watch each other type in the same post while dropping keyboard-navigable comments on each other's sections.
Outcome: Copy ships without emailing files back and forth, and the Teams tier's shared folders keep the queue organized as the post count grows.
You paste a chapter, ask for feedback on pacing after you've grown too close to it, then use command shortcuts to find the word you're circling.
Outcome: You get a second pair of eyes inside the draft rather than exporting to a chatbot, and your original phrasing survives in version history.
Use cases
- Draft a long essay and ask the AI for feedback on the argument before you publish.
- Write a Substack post with a co-author, both cursors live in the same document.
- Ask what's missing in an investor memo before you send it.
- Use command shortcuts to find the right word or generate a list mid-paragraph.
- Edit a novel chapter and ask for feedback on pacing once you're too close to it.
- Polish a cover letter with inline rewrites and tone adjustments.
- Collect keyboard-navigable comments from an editor on a feature draft.
- Send a read-only publishing link so a client can read without an account.
Setup time & first value
How long it actually takes to get something useful out of Lex — broken out by persona, not the marketing-page minute.
For existing account holders: minutes to first value — log in, open a document, and either start writing or paste a draft and ask for feedback. Collaborators need nothing installed; a shared link plus one-click login gets them typing on desktop or mobile web. New buyers have no path in at all while signups are closed.
Switching to or from Lex
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Google Docs: paste draft text into a new Lex document, then re-add editor comments as Lex comments since word-level formatting and suggestion history do not carry over.
- →From a chatbot tab: move the draft into the document itself and use Ask Lex feedback and inline rewrites so revisions stay next to the text they change.
- ↗To Google Docs: copy document text out and rebuild comments and suggestion history there, since Lex states track changes is still coming soon.
- ↗To Notion: move text into pages, accepting that Lex's in-document AI feedback and read-only publishing links have no direct equivalent.
