Built on world-class infrastructure
You approve the structure before a single word is written. No surprises, no wasted credits.
Drop in any public YouTube video. TubeBook reads it natively via Gemini — no manual transcript needed.
AI scores the video's "Data Density" and suggests an optimal word count so you know what to expect before committing.
NewChoose fidelity mode (High / Smart / Low), writing style, and target word count — before any generation begins.
NewReview the AI-generated chapter structure. Edit or reject chapters freely. Your credit is only spent once you confirm.
NewA formatted PDF with AI cover, chapter illustrations, and your chosen fonts — ready to publish or share.
Three modes. Three legal postures. You choose how original the output needs to be.
The ebook follows the exact structure, names, stories, and ideas of your transcript — ideal for repurposing your own content into a book.
The AI rewrites and restructures the source — names may change, flow is rebuilt, but the core content stays close to the original.
The video is a thematic seed only. The AI generates substantially original content — names, structure, and wording are all new. Safe for KDP, Gumroad, and commercial publishing.
After you paste a URL, TubeBook scores the video's content density and suggests an optimal word count. If your targets are mismatched — a short video with a 25k-word output — we warn you before you commit.
Choose the writing style that fits your audience before generating. The AI adapts its tone, vocabulary, and structure accordingly — from academic rigor to casual storytelling.
Click any style to preview the AI's tone
State-of-the-art AI reads your video natively and writes a structured book — coherent, publication-ready prose, not a transcript dump.
High Fidelity for content repurposing, Smart Adapt for brand refresh, Low Fidelity for fully commercial-ready original ebooks — legal clarity built in.
Professional, Conversational, Stoic, Scientific, Narrative, Academic, Motivational, Minimalist — chosen before generation so the AI writes in your voice from page one.
Before you commit a credit, see a score for your video's content richness, a suggested word count range, and a warning if your targets are mismatched.
Review and edit the full chapter structure before generation starts. No credit is spent until you've approved the outline.
Output length is set by you — not by the video. A 5-minute video can produce a 5,000-word guide or a 25,000-word deep dive if the content supports it.
Watch your ebook generate in real time. The dashboard polls every 3 seconds showing the active pipeline step and progress percentage.
Gemini 3 Pro Image generates a custom cover and unique per-chapter illustrations that match your content's theme and fidelity mode.
All files in private owner-scoped buckets. Row-level security on every database table. Your content is yours alone — always.
I used Low Fidelity mode on a public finance video and got a 22,000-word ebook I'm now selling on Amazon KDP. The writing style I picked matched my brand perfectly.
I repurposed my entire 40-video training series using High Fidelity mode. Each video became a chapter. My own content, finally in a book.
The TOC preview changed everything — I edited two chapters before approving and the final ebook was exactly right. My email list grew 3× in two months.
