Every option in the catalog for when you need to give an assistant durable memory across sessions — 5 AI agent memory and RAG services, 5 of them free or freemium, with the pricing tier printed on every row.
Flocci AI Tools lists 5 of them, ordered free tiers first: Letta, Mem0, Ragie, Supermemory and Zep. Every one of them is free or has a free tier. Each entry states what it uniquely does rather than a score.
None of these are marked fully free — they are freemium, trial or paid. The Completely Free AI Tools collection lists the 115 entries in the catalog that carry no paid plan at all.
