FOLIO · 2 min read · v3.2

FOLIO turns a folder of markdown into a published, typeset knowledge base. Point it at your repo and it drafts the pages you're missing, keeps every heading in sync with your code, and shows you which words your readers actually get through.

Install with npm i -g folio, then run folio publish from any project. Your docs ship in seconds, beautifully typeset and versioned with your code.

Features

A knowledge base that reads like a book, works like a product.

Typeset beautifully, search everything, and keep every page in sync with the code it describes.

Typeset like a book

Editorial-grade typography — serif display, real margins, drop caps — so your docs feel as good as they read.

Synced to your code

Connect a repo and FOLIO follows every push — new endpoints, renamed flags and drift are caught before readers notice.

Learn more →

AI drafts from source

Give it a codebase and it drafts the missing pages in your voice — you review, then publish. No blank page ever again.

Learn more →

Search that works

Full-text search with typo tolerance and code-aware snippets. Readers find the answer instead of filing a ticket.

Learn more →

Read analytics

See which paragraphs people finish, where they bail, and what they search for — then write where it matters.

Versioned like git

Every change is a revision you can diff, review and roll back. Docs get the same rigor as code, finally.

How it works

Three steps to docs worth reading.

Connect

Point FOLIO at your repo, markdown files or knowledge base. It maps what you have and what's missing.

Draft

AI writes the gaps in your voice from the source. You review, edit and approve like a real editor.

Publish

Ship typeset, searchable pages that stay in sync with every push — and measure what people actually read.

Customers

Teams whose docs stopped being a graveyard.

"We moved off a wiki that nobody touched and onto FOLIO. Support tickets dropped 62% in a quarter — people just find the answer now."

Mina Reyes

Head of Support, NOVARA

★★★★★

"The git sync is the magic. Docs drift is gone — when the API changes, the page changes. Reviewing a docs PR finally feels like code."

Tomás Hale

Staff Engineer, TIDEPOOL

★★★★★

"It typesets our docs so beautifully that people actually read them. Our onboarding went from a PDF to a book, and new hires thank us."

Questions, answered.

What makes FOLIO different from a wiki? +

A wiki stores words; FOLIO treats docs as a product. It typesets them like a book, syncs them with your code, drafts gaps with AI, and measures what readers actually read. The difference is the difference between a filing cabinet and a published work.

How does the git sync work? +

Connect a repo and FOLIO watches every push. When an endpoint, flag or signature changes, it flags the pages that reference it and suggests an update. You review the diff and merge — docs never drift again.

Will the AI write in my voice? +

Yes. It learns tone, terminology and structure from your existing pages, then drafts new ones to match. You approve every word before it publishes — the AI is a draft-writer, not an author.

Is my documentation data safe? +

Yes. FOLIO is SOC 2 Type II certified with SSO and encryption everywhere. We never train models on your docs, and you can export or delete your content at any time.
