Free Manuscript Pacing Analyzer

Paste a scene, chapter, or whole manuscript to see its pacing rhythm, sentence-length mix, and dialogue balance — the rhythms an editor notices first.

100% private: your text is analyzed entirely in your browser and never uploaded.

This is a glimpse of what Bookshaper does for a whole manuscript

This page reads raw text you paste in. Bookshaper works on your whole manuscript — organized into parts, chapters and scenes — in the same app that styles it and produces the finished EPUB or print-ready PDF. Nothing is rewritten without your say-so.

Bookshaper uses AI for proofreading, revision, line editing, expansion, dialogue analysis, and select generation features (such as back-cover blurbs and cover concepts). Your manuscripts are stored locally. We do not authorize AI providers to train on your manuscripts, and we configure available no-retention controls on every request; because these features run on third-party AI platforms, this protection relies on each provider honoring its default API terms.
