Does SQLite + FTS5 really beat Pinecone for AI agent memory?

Yes—for latency, cost, offline use. Pinecone edges massive scale, but agents rarely need it.

How do I set up BrainDB for my AI project?

npm i braindb, init DB, insert memories with types. Searches hybrid by default. Zero config.

Not die—pivot to enterprise scale. But for devs and prototypes? SQLite owns.

Everyone's chasing vector databases for AI memory. But one dev just proved SQLite + FTS5 does it better—faster, free, offline—in a single file.
