AI Book Writer is an AI writing tool that drafts clear, on-tone copy from a short prompt, then lets you regenerate or edit until it sounds like you. It runs free on Free.ai with no sign-up required to get started.
AI Book Writer is built for writers, marketers, and anyone facing a blank page who wants a strong first draft to react to. It covers posts, bios, scripts, letters, long-form drafts, and other written content — pick this tool when that’s what you need.
Just a short prompt — a topic, a few key points, and the tone you want. AI Book Writer drafts it for you, and you can regenerate or tweak from there.
Yes. You get 2,500 free tokens per day with no account at all, or 30,000 tokens/day with a free account. AI Book Writer draws from that daily pool; if you need more, token packs start at $1.
AI Book Writer outputs plain, copy-ready text. Copy it straight out, or export it — signed-in users can save and revisit results from their history.
Give AI Book Writer context: who it’s for, the tone you want, and roughly how long. The more direction you give, the closer the first draft lands — then regenerate or edit to taste.
Yes. Text you generate with AI Book Writer is yours to publish, edit, and use commercially. We claim no rights over your output.
No. Use AI Book Writer immediately as a guest. A free account doubles your daily tokens to 30,000, saves your history, and unlocks larger inputs — but it is optional.
What you type into AI Book Writer is not stored beyond the share window and is not used to train models. Signed-in users can choose to save results to their history.
AI Book Writer runs on best-in-class open-source AI models on our own infrastructure — no third-party API keys, no per-call surcharge. We update the underlying models as better ones are released.
Yes. AI Book Writer works in any modern mobile browser — the layout adapts to your screen, so you can use it on a phone or tablet with no app to install.
A lot. Beyond AI Book Writer, Free.ai bundles posts, bios, scripts, letters, long-form drafts, and other written content alongside hundreds of other free AI tools — chat, images, audio, video, code, and more — all sharing the same daily token pool. Browse the categories to find your next one.
