Self-hosted AI companion

Runs the self-hosted companion cookbook in examples/cookbooks/self_hosted_companion/. It remembers a notes folder in the cognee dataset self_hosted_companion, then answers messages about it; each chat is saved to memory, so a later one knows it. Setup, the scripts and what each one does are in the cookbook's README.md.

Run every command from the repo root.

Steps

Without a notes folder of the user's own, or to see it work first, leave out <folder> below: the run then uses sample notes (the [setup] line says so). It needs only LLM_API_KEY. Tell the user the answer comes from sample notes.

1. Run uv run python examples/cookbooks/self_hosted_companion/self_hosted_companion.py --check <folder> with the notes folder the user named.
   • Exit 0: go to step 2.
   • Exit 2: each [setup] MISSING: line names one fix. Tell the user which line to fix, using the README's "What it needs" table, and stop.
2. You can't type into the interactive chat, so pass the user's message with --ask: uv run python examples/cookbooks/self_hosted_companion/self_hosted_companion.py <folder> --ask "...". Once the folder is remembered, later messages only need uv run python examples/cookbooks/self_hosted_companion/scripts/chat.py --ask "...".
3. The answer is everything after [chat] companion>. Give it to the user. Each --ask is its own chat session, saved to memory, so a later one knows it.
4. If a script fails, self_hosted_companion.py exits 1 with a line naming what went wrong. Run that script from examples/cookbooks/self_hosted_companion/scripts/ on its own to look closer.

Rules

• The notes are the user's private files. Don't quote them beyond what answers the question, and don't print .env.
• Every run uses LLM credits, so run it only when the user asked for it.
• A sample run forgets the cookbook's dataset self_hosted_companion before it ingests (the [clear] line). On the user's own data, pass --clear only when they asked to start over: it forgets everything the dataset holds, including the earlier chats.
• Don't pass --ui unless the user asked to browse the graph: it keeps running until Ctrl+C.

Clean up

uv run cognee-cli forget --dataset self_hosted_companion
