- Full manuscript analysis

What is in the report
Word and chapter counts, a genre and style read, a market score, a visual story-structure arc, character cards with roles and arcs, and actionable notes on what is working and what needs attention.
A good first step
The report is free with any manuscript, so it is a low-risk way to see where your book stands before you commit to deeper editing or a translation.
Frequently asked
Is my manuscript private?
Yes. Your manuscript is processed in your browser and sent directly to the AI provider you choose (OpenAI, Anthropic, or Google). Chapterra never stores your content on its servers.
How is this free?
The goal is to keep a genuinely useful free proofreading tool available to everyone. It may not be free forever, and a payment system is coming before the most powerful models are unlocked, but the free and low-cost tools work great for most things.
