A private AI agent that lives where you already chat.

One human, one bot, one set of keys — yours. No SaaS account, no shared infrastructure, no strangers in your data.

Why Celindor

It's yours, not theirs.

Yours alone

You bring your own keys and your own chat channel. Each user's costs, rate limits, and conversation history live with that user — never pooled.

Private by default

Your bot ignores everyone except you. There's no public address, no admin backdoor, no shared agent that could leak across accounts.

Built around you

Identity, voice, memory, and rules are per-user. The agent learns who you are over time and adapts — without exposing any of it to anyone else.

How it works

Three steps. About two minutes.

1
Pick a chat channel
Today that's Telegram — message @BotFather, send /newbot, and copy the token. More channels are coming.
2
Sign up here
Paste your channel details and an Anthropic API key (or Claude Code OAuth token). We encrypt them before they touch the database.
3
Start talking
Your agent comes online within seconds. It remembers facts about you, runs tools on your behalf, and asks before doing anything risky.

The trust model

No shared keys. No shared sessions.

Every user gets their own private agent instance. The daemon spawns a separate event loop per user.
All credentials — Anthropic, OpenAI, GitHub — are encrypted at rest with AES-256-GCM and decrypted only to serve your turn.
Each chat session runs in its own ephemeral Docker sandbox. Tools that touch the file system stay inside that container.
Your data is row-isolated by user id. Row-level security in Postgres prevents cross-user reads even if the web were ever bypassed.

Questions

A few things people ask.

How much does it cost?

Whatever Anthropic charges you for tokens, plus optional OpenAI for embeddings. Celindor itself is free and open source — there's no Celindor subscription.

Can a stranger find and use my agent?

Even if they discover your chat handle, the gateway silently drops every message that doesn't come from your linked account.

Where does my data live?

In a Postgres database shared across users only at the row level — every table is keyed by your user id and isolated by row-level security. The agent runs on a single Linux box. Nothing leaves your record.
