What AI Writing Features Does Lex Offer?

Updated

Lex provides AI assistance at several points in the writing process: feedback on a draft, brainstorming, rewriting, word-choice commands, idea lists, title suggestions, and alternative versions you can try without losing your current text. These features are available to existing Lex accounts only—the site states that Lex is no longer accepting new customers, while existing accounts keep working as usual. If you don't already have an account, you can't sign up to use these tools.

Core AI features

Feature What it does When it's useful
AI Feedback Ask the AI for feedback on your draft, brainstorm ideas, or rewrite any part of it Early drafts where you want a second opinion, or passages that need rephrasing
Commands Keyboard-accessible AI shortcuts to find the best word or generate a list of ideas Mid-sentence when a word isn't landing, or when you're stuck on what to say next
Title Ideas One click produces a list of title suggestions After the draft is done and you need a headline
Versions Try a different way of saying something without losing what you already wrote Comparing phrasings before committing to a rewrite

How the features fit together

The AI tools are built into a collaborative document editor rather than offered as a separate chatbot. That matters for workflow: you can request feedback, apply a command, or generate titles while the document stays open, and collaborators see the same file. The site describes the product as a minimalist writing surface with AI acting as a real-time editor.

A practical sequence looks like this:

  1. Draft normally. Write in the document without invoking AI.
  2. Get feedback. Ask the AI for feedback on the draft or a section, and use its response to spot unclear passages.
  3. Rewrite selectively. Use the rewrite option or Commands on specific sentences rather than the whole document.
  4. Test alternatives. Use Versions to try a different phrasing while keeping the original intact, then keep whichever reads better.
  5. Generate titles. Run Title Ideas once the body is settled, since a good title depends on the finished argument.

Limits worth knowing before you rely on it

  • No new accounts. The AI features are only reachable through an existing Lex login. The site's "Existing users" login is the entry point.
  • Track Changes is not yet available. The site lists it as "coming soon," so version comparison and review currently depend on Versions and manual editing rather than a full suggestion-and-accept workflow.
  • Collaboration needs no app install. Sharing a link lets others collaborate in the browser, which is relevant if you plan to combine AI editing with feedback from other people.

Choosing whether it fits your workflow

If you already have a Lex account and want AI help inside a clean document editor—feedback, rewrites, word choice, titles—the feature set covers those tasks directly. If you need tracked suggestions from collaborators, that capability is still pending. And if you're evaluating Lex as a new tool, the closed signup means the AI features aren't an option regardless of how well they match your needs.
