The writing app for people who want to keep every word.
Write. Version. Think further with AI.
bun.ink does everything a great writing app does — and adds real version control on top. Your texts stay yours, safe in Europe, reachable from any browser.
The name
bun.ink starts with bun
The character 文 can be read as “bun” in Japanese and points to literature or writing. bun.ink joins that idea with ink: a place for words, drafts, and writing that stays.
Everything a writing app should do
No relearning, no compromises. bun.ink is a comfortable home for your texts, with a clean editor, light and dark themes, and a Zen mode for focused writing.
A calm, capable editor
Comfortable rich-text writing that saves clean Markdown underneath — formatting that lasts, text that stays portable. Everything can be exported as Markdown or a text file at any time.
Projects and folders
Keep manuscripts, articles and notes neatly structured, exactly the way you think.
Snippets and text building blocks
Drop in recurring phrases with a quick trigger instead of typing them again and again.
Search and replace across everything
Find any passage across a whole project and replace it in one pass — as precise as a code editor.
What sets bun.ink apart
Every version stays — version control that thinks with you
Most writing apps only ever show you the latest state. bun.ink keeps your full history. Through its GitHub connection your texts become version-controlled — "Git for writers", without forcing the jargon on you.
Try a bold rewrite, keep every version safe, and return to any state at any time. Nothing you wrote is ever truly lost.
Keep every version
Every saved branch of a version is preserved. Return to an earlier draft whenever you want.
Branches for drafts and variants
Explore a different ending or a second version in parallel — without touching your main text. Later, you can bring everything back into one document.
Compare versions
See exactly what changed between two branches of a text, sentence by sentence.
Your gateway to writing with AI
Open your texts to AI — on your terms
Through the optional GitHub connection, your texts are easy for AI agents to reach there: review a chapter, run a style analysis, suggest an edit, draft the next section, tidy a rough passage, or check a text for logical gaps.
The agent proposes; you decide what to keep. Changes arrive as clear, reviewable suggestions — never silent overwrites. The text remains in your hands; you simply work much faster and more efficiently.
It's the same open foundation developers trust, now working for your writing. No lock-in, no black box.
Safe, and at home in Europe
Your words deserve a trustworthy place
bun.ink doesn't run on an anonymous hyperscaler. Your data lives in Europe, under European data protection.
Data location Germany
Stored in Europe and handled under the GDPR — not shipped off to wherever happens to be cheapest.
A small, reliable home
Built on Appwrite, a focused and dependable company — not a faceless Google or AWS data centre.
Encrypted where it counts
Sensitive access keys are stored encrypted with AES-256, never in plain text.
Your texts are safe — and they're yours
Every day, your data is backed up automatically and encrypted. A lost device or a wrong click doesn't mean a lost manuscript.
Your writing is stored as plain Markdown — portable, future-proof and free of lock-in. What you write, you can always take with you.
