A ghostwritten novel runs $5,000-18,000 for common genres and takes months (Reedsy 2026 marketplace data). Instawritr does the same job on your own machine, once, for $149.

It is a complete publishing pipeline, not a writing assistant. A premise goes in; a synopsis, a full manuscript with human-like prose craft (windowed cadence, genre tone vectors, cliché elimination), a QA pass, a cover, an EPUB, a complete audiobook (local Kokoro TTS, no per-word cost), and a 30-day marketing asset bundle come out, staged to 6 stores: Apple Books, Google Play, Kobo and Barnes & Noble for ebooks, Spotify for Authors and InAudio for audio.

Quality is measured, not promised. The QA loop scores the manuscript and rewrites weak spots until it clears a 3-part gate: 90+, zero open critical defects, and an empty revision list. A live run went 66 to 87 to 90 to 95 to 99. Books built by this pipeline are on sale in 51 Apple Books stores today — full record at instawritr.com/teardown.

Built-in marketing: automatically mines emotional peak scenes, quotes, and tropes to generate 30 days of social media cards (square, portrait, vertical) with zero extra reading tokens.

5,000-word short story to 120,000-word novel, same bar. Duplicate tracker stops writing the same book twice.
