ChainMemory gives your AI agents persistent memory that belongs to YOU — not to a single vendor.

Save a memory in ChatGPT, recall it in Claude or Gemini. Available via Chrome extension, MCP server (npm), or REST API. Every memory gets a cryptographic fingerprint and project states are anchored with Merkle proofs, so anyone can independently verify integrity — no trust required.

Memories consolidate into a structured Project Brain (decisions, milestones, risks) instead of a pile of raw notes. Multi-agent native: Claude, Cursor and GPT share one consolidated state. Free tier available.

PouchDB features and specs

Offline-first Architecture
PouchDB is designed for offline-first applications, allowing users to access and interact with data without requiring a constant internet connection. It automatically syncs with a CouchDB-compatible server when a connection is available.
Cross-Platform Compatibility
PouchDB runs in the browser, Node.js, and other platforms, enabling developers to build applications that work consistently across desktop and mobile devices.
CouchDB Compatibility
Being compatible with CouchDB, PouchDB allows developers to easily sync data between the client and server, leveraging CouchDB's replication and conflict resolution features.
Easy to Use
PouchDB provides a simple API that is easy to understand and use, which can speed up the development process, especially for developers familiar with document-based databases.
Rich Querying Capabilities
PouchDB supports MapReduce, Mango queries, and a few advanced indexing features that offer flexible ways to query data based on specific requirements.

Possible disadvantages of PouchDB

Limited Built-in Security
While PouchDB can work offline, securing data at rest or implementing authentication requires additional work, as it does not provide substantial security features out of the box.
Database Size Limitations
When used in the browser, PouchDB's storage capacity is limited by the browser's storage limits, which might not be sufficient for certain applications with large datasets.
Performance Overhead
PouchDB can introduce some performance overhead due to its JavaScript implementation and the use of MapReduce on larger datasets, which may not be as fast as native database implementations.
Complex Conflict Resolution
While conflict resolution is supported, handling conflicts can become complex, requiring developers to implement robust conflict management strategies within their applications.
Dependency on CouchDB
Although PouchDB is designed to work offline, the synchronization capabilities depend on CouchDB (or a compatible server), meaning that certain features may not work without such a backend setup.

How to Sync Anything: Building a Sync Engine from Scratch — Part 3
The CouchDB Replication Protocol is implemented in CouchDB itself, so that covers our server component. Then there is the PouchDB project implementing the same protocol in JavaScript targeted at Browser and Node.js applications; that covers your clients and dev servers. - Source: dev.to / 5 months ago
Linear sent me down a local-first rabbit hole
Local first is amazing. I have been building a local first application for Invoicing since 2020 called Upcount https://www.upcount.app/. First I used PouchDB which is also awesome https://pouchdb.com/ but now switched to SQLite and Turso https://turso.tech/ which seems to fit my needs much better. - Source: Hacker News / about 1 year ago
What is CouchDB? #2: Guidelines & Use Cases
We’ve covered this a bit already, so let’s introduce something new about it: CouchDB’s sibling technology, PouchDB. Written in JavaScript, it’s designed to save your work locally on your device and then sync with your CouchDB when you’re back online, and can also be set up to automatically handle conflicts. Where automation won’t do, you can use CouchDB’s built-in UI, Fauxton, if you haven’t built your own... - Source: dev.to / about 1 year ago
Local-first software: You own your data, in spite of the cloud
CouchDB on the serer and PouchDB on the client was an attempt at making such an environment: - https://couchdb.apache.org/ - https://pouchdb.com/ Also some more pondering on local-first application development from a "few" (~10) years back can be found here: https://unhosted.org/. - Source: Hacker News / about 1 year ago
