Students and writers working on long documents who want sources, outline and draft together; the free AI allowance is small and inconsistently described.

Kenning's take

What it does

Strut is a writing app for long pieces such as essays, articles, reports and manuscripts. It keeps notes, sources, an outline and the draft together, and an AI assistant can expand, outline, critique or rewrite passages in the writer's own voice. The workspace is free, with a limited AI allowance, and Pro adds unlimited projects and a monthly AI budget.

• Notes, sources, outline and draft in one project
• Eight AI writing operations including expand, critique and rewrite
• Voice Profile to keep revisions in the writer's voice
• Import PDF, Word, Excel and Markdown sources
• Version snapshots and Markdown export
• Invite reviewers for inline comments

Who it suits. Students, writers and professionals working on long documents.
