Cloud E2EE Local-first v1.4 — markdown + html workspace

Your notes, your, pace.

Start writing instantly — no signup, no friction. kashi.io lives in your browser, organizes your thinking, and adds cloud intelligence only when you want it. When you sign in, optional end-to-end encryption for the synced library keeps ciphertext on the server: AES-256-GCM in Web Crypto with a passphrase and a separate six-word recovery phrase — decryption happens only in your browser.

Why kashi.io

Three ideas, one app.

01 / Start instantly
✦

One click to write

Open the app and write. No forced account. Autosave, word goals, and split editor–preview keep you in flow from the first keystroke.

02 / Stay organized
◈

Notes that stay usable

Folders, tags, saved searches, backlinks, and a graph view connect your ideas. Tasks extract into boards with Today, Overdue, and kanban columns.

03 / Extend when ready
⬡

Optional cloud & AI

Sign in to sync, upload files, record meetings, and chat with AI grounded in your own notes — not the open web by default. Turn on Cloud encrypt in Account to sync your workspace library as end-to-end encrypted ciphertext (AES-256-GCM in Web Crypto); attachments are not covered yet.

Privacy & Sync

Everything starts local. You decide when and whether to put it in the cloud — nothing is silently overwritten.

Optional E2EE Encrypted cloud library sync

Enable Cloud encrypt after sign-in: your full Inkwell workspace JSON is encrypted in the browser with AES-256-GCM before upload. The server stores only opaque ciphertext plus key wraps.

You choose a passphrase and receive a separate six-word recovery phrase — both independently wrap the data encryption key (dual-wrap format v2). Unlocking derives keys via PBKDF2 and keeps material in session storage for the session.

Attachments and meeting audio are still ordinary cloud uploads today — only the synced library blob is end-to-end encrypted.
