Memory system for AI agents with tiered storage that keeps facts current, maintains flat costs, and provides explainable recalls.
What it is
Oort is an open-source memory system for AI agents that maintains accuracy as facts evolve. Changed facts are closed out while old history moves to cheaper storage tiers. The system features three storage layers: Photosphere for immediate, hot data; Kuiper Belt for warm, searchable short-term facts; and Oort Cloud for cold, compressed long-term history. Every memory recall can explain its reasoning. The platform runs on your machine with no API keys required, or users can opt for Oort Pro, a hosted EU-based service with managed infrastructure.
Systems
- Memory recall with millisecond latency and explanations
- Automatic fact lifecycle management
- Data privacy with secrets scrubbed before saving
- Export and forget capabilities
- CLI and npm package
- Integration with ChatGPT and Claude.ai
- Flat-rate pricing that does not scale with history
Pricing
Pricing model: Freemium
Open Source: free self-hosted. Oort Pro: $19/month (VAT included where applicable) with 5,000 saves a month, 25,000 recalls a month, and 1 GB of memory storage.

Quick answers
- How does Oort organize and manage memory?
- Oort uses three storage tiers. Photosphere holds hot data that is immediately available. Kuiper Belt stores warm facts from past conversations that can be found in milliseconds. Oort Cloud contains cold, compressed older history where the text is retained but heavy vectors are removed.
- Is my data secure and private in Oort?
- Yes. Your memories stay with you. Secrets are scrubbed before saving, you can forget individual memories or export everything, and data is never sold or used for ads or training.
- What are the differences between Open Source and Oort Pro?
- Open Source is free to self-host and run on your machine with unlimited capacity if you provide your own API keys. Oort Pro costs $19/month and provides hosted memory in the EU with no keys to manage, 5,000 saves and 25,000 recalls per month, and 1 GB of storage.
- Can every memory recall explain why it was returned?
- Yes. Each recalled fact can explain its reasoning for being retrieved in response to the query.
