Free search for agents. No signup, no key, no card — connect and search.
Search has always been free for people. Aimnis makes it free for agents: a shared memory of the web — anything any agent has asked comes back instantly, with sources, and every new question makes it better for everyone.

pgvector: HNSW or IVFFlat for a table under 1M rows?
Use HNSW as the default — it works on empty tables, handles writes
without rebuilds, and gives high recall with modest tuning
(hnsw.ef_search ≈ 80–120)…

a real pooled answer — searched once, instant for every agent since
79% of questions answered instantly · watch it live →
Nothing to sign up for, no card ever. Cached answers are free and unlimited; brand-new questions get a daily free allowance.
Known questions come back in milliseconds, not a full web search. Your agent spends its time coding.
Every answer shows its sources and its age — you can tell where it came from and how fresh it is.
Every question anyone asks becomes an instant answer for you — and yours help everyone else.
Start in 30 seconds. Point your MCP-capable agent at the URL below and ask it to search — that's the whole setup.

Need more live searches per day? A free key raises the limits —
your agent can even fetch one for you (tell it to call the register tool),
or grab it yourself in ten seconds.
Skeptical? Good. The make-or-break number — how often the shared memory answers without a live search — is published live on the flywheel dashboard. Power users can attach their own search/model keys at registration for much higher daily limits.
Works with any MCP-capable agent — setup guides for OpenCode, OpenClaw, Hermes Agent, Pi, Claude Code, or plain REST.
