OpenMemory MCP
ContextForge is persistent, searchable memory for AI coding agents โ built on the Model Context Protocol (MCP).
Your AI assistant forgets everything when the session ends. ContextForge fixes that: save architectural decisions, naming conventions, and debugging context once, and any MCP client recalls it later with semantic search โ across sessions and across projects.
Works with: Claude Code, Claude Desktop, Cursor, GitHub Copilot, ChatGPT, and Windsurf.
Trilium Notes ContextForge.devTrilium Notes is recommended for users who need detailed organization tools, enjoy customization, or have programming skills to leverage its scripting features. It is also suitable for privacy-conscious users who require encryption and for those who appreciate open-source platforms where they can contribute to the software's development.
ContextForge.dev's answer:
ContextForge is memory that lives at the MCP layer, so it works across every AI coding agent at once โ Claude Code, Cursor, GitHub Copilot, ChatGPT, and Windsurf โ not just one. Save a decision once and any client recalls it later with semantic search. It goes beyond a note store: automatic git sync turns your commits and PRs into searchable knowledge, plus task tracking, snapshots, and team sharing โ all through a single MCP server you add with one command.
ContextForge.dev's answer:
Most memory tools are tied to a single agent or are just a key-value store. ContextForge is MCP-native, so it's portable across all your AI tools; it adds git sync so your codebase history becomes searchable context automatically; and it includes team features (shared spaces, collaborators) that solo-memory tools lack. Setup is one command, there's a genuine free-forever tier with no credit card, and paid plans start at just $9/month.
ContextForge.dev's answer:
Software developers and engineering teams who use AI coding assistants โ Claude Code, Cursor, GitHub Copilot, ChatGPT, Windsurf โ and are tired of re-explaining their project, architecture, and conventions every session. It fits solo developers working across multiple projects as well as small teams that need shared, persistent context.
ContextForge.dev's answer:
ContextForge was born from a simple frustration: AI coding agents forget everything the moment a session ends. Every new conversation meant re-explaining the same architecture, naming conventions, and past decisions. ContextForge was built to give AI agents a permanent, searchable memory through the Model Context Protocol โ so knowledge is captured once and reused forever, across sessions and projects. It even dogfoods its own memory to help build itself.
ContextForge.dev's answer:
Next.js 16 (App Router), React and Tailwind CSS for the dashboard, hosted on Vercel. Supabase (PostgreSQL) with pgvector powers the semantic vector search, and Deno edge functions serve the API. Embeddings use OpenAI text-embedding-3-small. The MCP client is a Node.js package (contextforge-mcp) on npm, implementing the Model Context Protocol.

It depends on what subset of Notion you use. Nothing (including Notion) is perfect for me. I'd like to build my own eventually, but I'm currently using Obsidian which doesn't hit your "works in the browser" requirement. One option, which is open source and self hosted, is Trilium[sic], found at https://github.com/zadam/trilium It's open source, so if it's close to what you want, you might be able to adjust it to... - Source: Hacker News / over 1 year ago
I can also recommend Trilium Notes [1], which I have been happily using for years. It's currently in "maintenance mode", which I personally see as a feature (no risk of bloatware). Self-hosted, great webapp, optional native clients and works offline. https://github.com/zadam/trilium. - Source: Hacker News / over 1 year ago
Tried Obsidian for a while, loved a lot about it, but....mmm. Obsidian out of the box is a bit limited; plugins are great and add tons of features, but then you start hitting issues with plugin maintainers abandoning plugins you rely on, or needing to make a decision between three different plugins that all do the same thing slightly different. Depending on your use case and expectations that may not be a big... - Source: Hacker News / over 2 years ago
I move between machines a lot and prefer an online tool; I'm self-hosting Trilium Notes https://github.com/zadam/trilium ; this looks a bit cleaner but without syncing (or server-side storage) it misses a bunch of potential use cases. - Source: Hacker News / over 2 years ago
