Character by Onion Core — clone your own voice, build characters who speak and remember, and chat with them through a private brain on your own machines. No per-message cloud AI. Your characters are files you own.
Continue with Onion IDThe passcode stays on this device. Browsing and editing work even when the voice engine is offline — only generating waits.
The best clones come from 30 seconds of clear, close speech. The clone flow offers a balanced script that covers every sound in English — read it and the voice learns fast.
Type it, direct it, hear it. Voices are directed like actors.
Two voices perform one script — rendered as a single clip. Start each line with A: or B:.
One rule: the voice must be your own voice, or a character you created. That goes for recordings, uploads, and links alike.
10 seconds to 5 minutes of clear speech. We pull the voice out of it.

Standalone lorebooks — worlds of keyword-triggered facts any character can carry. Export and share them as files.
Personas are who you are in a chat. Characters remember you by the persona you're wearing.
You are admin: no limits apply to you, ever. These buttons set the tier structure that applies to non-admin users. Premium charging is not wired — flipping it later is a separate switch.
Premium unlocks more voices, longer clips, scene mode, priority queue, and trained voices later. COMING SOON — no payment anything, by design.
Brains and voices run on your own infrastructure, under the Onion Core operator identity. No per-message cloud AI cost, no outside service sees your device.
