The AI journal that keeps your secrets
Inkling gets to know you and answers questions about your own life — in Hearth, or from ChatGPT and Claude. Your words are always stored encrypted, every AI glance burns after reading, and Private Vault mode makes your journal unreadable to anyone but you. Free, on every plan.
Free forever · unlimited entries · no card needed
The whole point
Every entry is envelope-encrypted before it's stored — in every mode, on every plan. Plaintext at rest doesn't exist here.
When Inkling reflects on an entry, the words are seen for a heartbeat — then the glance burns away. Nothing stored, nothing logged, nothing ever used to train anyone's AI. We built the fire; your words only pass through it.
Flip one switch and "we don't read it" becomes "we can't": our spare key is deleted, and only your passphrase opens your words. Free on every plan.
Erase your account and every key vanishes with it — including our spare. Your words become unreadable forever, even in backups.
Rituals, not metrics
Ask your journal
Inkling's memory answers in Hearth — or connect ChatGPT or Claude and ask from there. Answers are decrypted only for the moment it takes to reply, and every glance burns after reading.
Voice entries
Some days won't type. Hit record and ramble — Inkling turns your voice into words you can edit, and the recording is sealed on your device before it goes anywhere. Transcription burns after reading: audio in, words out, nothing kept. Photos work the same way — shrunk and stripped of location data before they ever leave your hands.
The Unsent Vault
The angry reply, the apology, the goodbye. Write it, seal it, and let it go — Hearth gently checks in thirty days later.
Future Me
Seal an encrypted letter to your future self. It stays sealed until the day you chose — not a moment sooner.
Inkling
Your living-ink familiar glows when you show up and recolors with your theme. It celebrates consistency and never shames a missed day.
Make it yours
Swap the whole mood in a tap — the page, the type, and Inkling itself recolor to match how you feel today.
AI TWIN
Build a public chatbot that talks like you — your words, your rules. It only knows what you choose to publish to it; your journal stays sealed. Share it as a page or drop it on your site with one script tag.
Honest pricing
Free gets real AI every day — a reflection from Inkling, unlimited entries, no card. Glow adds the rest: chat, voice entries, deep memory, and the connector that lets your own AI ask your journal. Cancel in two taps — we don't do roach motels.

From Kindling, our blog
A journal that remembers is a journal you can question — even from ChatGPT.
Seen for a heartbeat, kept by no one, trained on never. The pipes behind the phrase.
One switch turns "we don't read it" into "we can't." Here's the cryptography.
On your phone
Hearth already works like an app — offline drafts, a home-screen icon, the whole thing. On iPhone: Share → Add to Home Screen. On Android and desktop: Install.
Real App Store and Google Play apps are being built, with Face ID, widgets and the same encryption. Not out yet, and we would rather say so than take a pre-order.
Already have Hearth? The switch is in Settings → Companion.
