GitHub · Issues · Docs 👋 Questions, ideas, bugs → GitHub Issues · Discussions If Vektori has been useful, a ⭐ goes a long way. --- Why Vektori Building agents that actually remember people is harder than it looks: - Facts aren't enough. Knowing a user prefers WhatsApp is different from knowing they've asked three times and are getting frustrated. Most systems give you the what, not the why or how it changed. - Patterns stay invisible. Spotting that someone's tone has been shifting across sessions requires more than point-in-time retrieval — you need to see the trajectory. - Context overhead explodes. Stuffing raw conversation history into every prompt doesn't scale. You need structure, not just storage. Vektori solves this with a three-layer sentence graph . Agents don't just recall preferences — they understand how things got there. Search hits Facts, graph discovers Episodes, traces back to source Sentences. SQLite by default — swap to Postgres, Neo4j, Qdrant, or Milvus when you're ready to scale. --- Benchmarks Tested on long-horizon memory benchmarks — hundreds of turns, real user details buried deep in history.
