Maximem provides persistent, cross-app AI memory with Vity for personal use and Synap SDK for developers. It securely stores and syncs user context across ChatGPT, Claude, and Gemini — giving your AI tools the ability to remember everything while keeping your data private and encrypted.

Maximem is a private AI memory layer that stores and syncs user context across multiple LLM platforms. It enables ChatGPT, Claude, and Gemini to access persistent, personalized data during conversations — so your AI tools remember your preferences, past interactions, and relevant context.
The platform offers two main products: Vity for personal AI memory (consumer-facing) and Synap SDK for developers building AI applications that need long-term memory. Synap allows developers to ingest conversations, extract structured knowledge, and retrieve contextual memories with zero infrastructure management.
As a tool in the AI Memory category, Maximem targets both individual AI users who want persistent context across tools and developers building memory-enabled AI applications. Privacy is core — all data is encrypted and stored securely with user control.
Here are the standout features that make Maximem worth your attention:
Persistent memory that works across ChatGPT, Claude, Gemini, and other AI platforms simultaneously
Consumer-facing AI memory assistant that remembers your preferences and context across all your AI tools
SDK for adding long-term memory to AI applications — zero infrastructure, working memory in under 10 minutes
All data encrypted and stored securely — private by design with user control over what is remembered
Automatically extracts structured knowledge from conversations for intelligent memory retrieval
No vector databases to tune, no retrieval pipelines to build — Synap handles everything

Getting started with Maximem is straightforward. Here is a complete walkthrough:

Maximem addresses a fundamental limitation of current AI tools: they forget everything between sessions. By providing a secure, persistent memory layer that works across ChatGPT, Claude, and Gemini, it makes AI interactions genuinely more useful over time. The dual product approach (Vity for consumers, Synap for developers) covers both sides of the market. For AI power users frustrated by having to repeat context, Maximem provides the memory layer that LLMs need.
