# BetterDB

> Open-core context layer for AI agents: long-term memory, semantic caching,
> and retrieval in one SDK, built on open-source Valkey. Core SDK is open under
> MIT; a Pro tier adds proprietary features. BetterDB also ships Monitor, an
> observability layer for Valkey and Redis.

## AI SDK
- [AI SDK overview](https://betterdb.ai): agent memory, semantic cache, agent cache, and retrieval for AI agents on open Valkey
- [Agent memory](https://betterdb.ai/#memory): long-term memory your agent keeps across sessions, scoped and ranked by what matters
- [Semantic cache](https://betterdb.ai/#semantic-cache): catch paraphrased prompts and return answers from Valkey in under a millisecond
- [Agent cache](https://betterdb.ai/#ai-sdk-caching): exact-match caching for LLM calls, tool results, and session state across frameworks
- [Retrieval](https://betterdb.ai): typed retrieval over your own data, observable at every layer
- [Observability](https://betterdb.ai/#observability): every cache operation emits an OpenTelemetry span and updates Prometheus metrics
- [Comparisons](https://betterdb.ai/ai/comparison): how BetterDB compares to Mem0, Zep, Redis Iris, RedisVL, and Pinecone
