In their own words
Author's Forge
Author's Forge is a local-first writing app for drafting, organizing, formatting, and preparing books for publication. It structures work into libraries, series, books, and chapters, with front matter, back matter, and research notes. Formatting tools include presets, typography controls, trim-size and margin settings, live preview, and reusable themes. Outlining is supported, and exports include EPUB, PDF, DOCX, Markdown, and MP3 audiobook files. Core writing works offline without an account, and manuscripts are stored locally in standard file formats. Paid plans add AI tools for spellcheck, writing assistance, manuscript import, cover art, read aloud, and audiobook export. When AI features are used, portions of content may go to providers including OpenAI, Anthropic, and Google. The Free plan costs nothing and includes core writing features but no AI credits. Paid plans start at $20 a month; any paid plan includes a 7-day trial with 1,000 credits, and the selected plan is charged afterward unless canceled. Monthly AI credits reset and do not roll over. The app runs on macOS, Windows, and Linux.
