Show HN: Itsuki – open-source memory engine for AI agents (API and MCP) (itsuki.app)

Itsuki, a new open-source memory engine for AI agents, has been launched, making it possible to extract and serve structured memories from 26 connected tools using a single API key. This innovative platform allows users to interface with existing AI tools without the need for an ORM, relying instead on raw SQL with Postgres for data management. Itsuki aims to enhance the continuity of AI interactions by maintaining context and recalling specific details from past conversations—such as meeting schedules and decisions—across multiple sessions. During its early access phase, users can utilize the service for free, creating up to 100 memory saves per day. The significance of Itsuki for the AI/ML community lies in its potential to streamline workflows and improve user experience by ensuring that AI agents can remember important details, preferences, and historical context. This not only fosters conversational continuity but also enables more personalized interactions, allowing AI systems to engage with users in a more informed and relevant manner. The foundational approach of Itsuki promotes transparency in memory management, as its code and schemas are fully accessible under the Apache 2.0 license, paving the way for greater collaboration and innovation within the AI development community.
