The AI publishing studio for long-form knowledge.

Why VidBook exists

Plenty of people have a book in them: an idea they keep returning to, a recorded lesson, a folder of notes or an interview worth revisiting. Turning that into a book takes decisions about structure, facts, examples and what the reader needs. VidBook supplies a research brief, a draft and the editing tools; the author still makes those decisions.

Paste a link to a public YouTube video up to 3 hours long, and VidBook imports its captions as the transcript, or, on paid plans, transcribes the video if it has none. VidBook does not transcribe uploaded video or audio files. You can also upload the caption file from YouTube Studio, paste a transcript, add a permitted .txt, DOCX or text PDF, or start from a book idea that VidBook researches first. The pipeline assigns source chunks to chapters, generates an editable draft, and renders PDF, EPUB, and DOCX files. Grounding reduces drift but does not eliminate model errors, so authors must verify facts, quotations, permissions, voice, and layout before publishing.

The grounded pipeline

An outline maps source sections to chapters. The writer receives the assigned source chunks and summaries of preceding chapters. Validated results are checkpointed so a completed step can be recovered without writing it again. Source-review suggestions remain advisory; they do not certify facts, permissions or editorial quality.

We picked this architecture to split a long-form task into smaller, reviewable stages. Each chapter receives scoped source context and can be edited in the product. Splitting the work makes a draft easier to trace back to the source and revise. An AI draft still needs your review before it is accurate or ready to publish.

The hackathon

VidBook was built during the OpenAI × Outskill AI Builders Hackathon 2026 and was a winner. The announcement is on LinkedIn. VidBook is at vidbook.co, built for creators who work with long-form recorded material.

What the workflow includes

You can draft and edit chapters, generate AI front covers with no people or animals, download a free full-wrap paperback cover, prepare a listing kit, run an advisory compliance review and export PDF, EPUB or DOCX. Market Scout suggests market opportunities with AI-estimated scores, which are not sales data, and you can also make coloring books. VidBook does not submit books to stores, import private videos or live streams, operate your course or email platform, or guarantee sales. Check each store's requirements before distributing a book.
