Lex vs Type.ai

Lex

• Writers who want AI feedback on a draft instead of generated text
• People looking for a simpler shared-document editor with AI built in
• Trying several AI models on the same piece without separate subscriptions

Type.ai

• Novelists and screenwriters drafting with AI assistance
• Writers revising an existing manuscript imported from Word
• People who want chat and the draft in one window

Lex

• Free accounts get 30 Ask Lex messages a day, 5 saved-prompt runs a month and a small daily AI budget; premium models need Lex Pro.
• Lex Pro's AI use is metered: the plan includes $30 of AI credits a month, and heavier use can be covered by overage credits sold at cost.
• Lex runs in a desktop or mobile browser. An iOS app is offered to Pro subscribers as early access, and no desktop app is listed.
• Track changes is marked as coming soon on the homepage.

Type.ai

• The Free plan's credits do not replenish; after they run out, AI features stop until a paid plan is bought.
• Paid plans' monthly credits reset on the renewal date and do not roll over, and every AI feature draws on them.
• There is no native iOS or Android app, only a mobile web version that can be added to the home screen.
• A document is limited to 150,000 words, and the editor offers a single font with no size options.

Lex

Ask Lex

A chat panel for feedback, rewrites and brainstorming on the open document. Highlighting text, or tagging @Lex in a comment, asks about one passage. The AI model can be switched.

Checks

Runs line edits for brevity, grammar, readability and more, shown as highlights in the document. Clicking one shows the suggested edit and the reason for it.

Custom prompts and context

Saved prompts can be reused in Ask Lex and Checks and shared with others. Style guides and knowledge bases give the AI a voice to follow and background to draw on.

Versions and Rewind

Versions are named save points for trying another approach. Rewind is a timeline at the top of a document for scrubbing through past changes and restoring an earlier state.

Live collaboration and comments

A shared link gives edit or view-only access, with co-editing in real time and comment threads. Lex Teams is a paid add-on for unlimited group use of shared folders.

Export and API

Documents export to Word, PDF, Markdown, HTML and LaTeX, and an API can create, list and update documents with a key generated in settings.

Type.ai

Type Chat beside the draft

A chat assistant in the right pane reads the draft and can research, give feedback, brainstorm ideas or rewrite passages without copying text between tools.

Inline commands and Brushes

Pressing / opens a command palette that writes at the cursor. Highlighted text can be rewritten with a preset Brush or a custom prompt, then accepted or rejected inline.

Notes on the story

Notes hold details about characters, settings and scenes. They can be edited by hand or through chat, and are taken into account in writing help.

Custom Styles

A Style is a set of writing rules, generated from an uploaded sample of earlier work or built from scratch, that can be applied to new drafts.

Import, export and narration

Imports DOCX files, PDFs, images or a URL, and exports PDF, DOCX, HTML or Markdown, a view-only link, or an AI-narrated audio track.

Offline mode and version history

Writing and editing continue without a connection and sync across devices once back online. AI features do not work offline.
