redditI built a vector memory API for AI apps — 60% cheaper than Pinecone, no per-query fees Hey [r/SideProject](r/SideProject) — I just launched VectorVaultAI and wanted to share it here for feedback. \*\*The problem:\*\* Every time I built an AI agent, I kept solving the same problem — giving it persistent memory that survives across sessions. Existing solutions (Pinecone, Weaviate) work great but get expensive fast, and they charge you per query on top of storage. \*\*What I built:\*\* VectorVaultAI is a semantic vector memory layer for AI apps. You store knowledge with \`vault.remember()\`, retrieve it by meaning with \`vault.recall()\`, and inject it into your LLM's context. Three primitives, one API. \*\*Pricing:\*\* $0 free tier (1M vectors), $39/mo Pro (10M vectors, unlimited recalls). No per-query fees ever. \*\*Stack:\*\* pgvector + semantic embeddings, Python + TypeScript SDKs, sub-10ms recall. Would love brutal feedback — especially from anyone who's dealt with the memory problem in their own AI projects. What's missing? What would make you actually use this? 👉 vectorvaultai.com vectorvaultai.com
