View evidence profile →Lex is for writers who want the document to remain the center of the workflow. Its appeal is less about a long feature checklist than a fast canvas with AI assistance, comments and sharing. That simplicity is an advantage only if it survives the team's real revision process.
> Distinctive strength: A low-friction writing canvas where AI assistance does not replace the document. > > Where it stops being an advantage: It is not a complete brand-governance, publishing or research-verification system.
| Requirement | Current evidence | Buying consequence |
|---|---|---|
| Individual drafting | A free route exists for trying the editor and collaboration | Test the actual document loop first |
| Premium models | Pro is positioned as access to premium models and expanded use | Confirm current price and model limits in account |
| Shared team folders | Teams is the route for sustained group use | Test permissions and document ownership before migration |
| Training boundary | Lex says model providers are used through enterprise APIs and user work is not used to train models | Validate contract and retention for confidential work |
Run a real brief from outline to approved draft with two writers and one editor. Count context repeated across prompts, comments lost during revision, export cleanup, unsupported claims and time to accepted copy. Compare with the current editor using the same brief.
Avoid Lex when mandatory requirements include formal terminology enforcement, SSO/audit controls not documented for the proposed plan, or evidence retrieval. Compare Notion AI when the workspace already holds source material, Writer for enterprise governance and Sudowrite for fiction-specific ideation.
