Lex

Word processor with an AI editor built in

No new customers. Lex's homepage says it is no longer accepting new customers and that existing accounts keep working as usual (read 2026-10-20). Nothing on the site names a closing date. Source: the Lex homepage, read 20 October 2026.

Minimalist word processor with AI feedback on demand. Ask for checks on clarity, structure, or style; the draft stays yours. Free plan includes 30 AI checks a month; Pro at $18/mo adds unlimited checks and premium models.

What it does

Lex is a web-based word processor built around the idea that AI should behave like an editor, not a ghostwriter. You write; when you want feedback, you run checks that flag unclear passages, weak arguments, or style problems, or open a side chat about the draft.

The free plan includes 30 AI checks a month on smaller models. Pro at $18/mo (about $12/mo billed annually) unlocks unlimited checks and premium models, plus an iOS app and priority support. Discounted Pro pricing is available for students, academics, and nonprofits on request.

Lex raised a $2.75M seed round in 2023 and has kept a deliberately small feature surface: documents, comments, checks. It is aimed at people who write for a living and want assistance without surrendering the drafting.

AI stack

Multi-model: checks can run on GPT-4o, Claude Sonnet-class models, or open-weight models such as Llama 3, selectable per check.

From the AXIS Launch team

We like that Lex treats AI as an editor rather than an autocomplete — the draft stays the writer's, and the 30-checks-a-month free tier is a clean freemium line. If you're the maker: what share of your active users run AI checks weekly versus just writing in it?
