Open-source mymind alternatives

Memos is a personal timeline for quick notes that you host yourself. The idea is to write first and organize later: you save a thought in Markdown without choosing a title or folder, optionally attach images and files, and it lands on a chronological feed.

Finding things again relies on search, tag filters and a view of any given day on the timeline. You can pin important memos and save frequently used filters as views. New memos are private, and you decide per memo whether to keep it to yourself, show it to signed-in users or invite specific people, or make it public with a link. The project advertises zero telemetry and a full export of your data.

Memos is MIT licensed and built with Go on the back end, React on the front end and SQLite for storage. The quickest way to run it is a Docker container, with other options in the deployment guide, and there is a live demo to try first. Releases follow a year-and-month version scheme.

NoteGen is a local-first Markdown note-taking app built around the idea of capturing first and organizing later. It helps collect scattered snippets, records and clippings and then uses AI to arrange them into clear notes, acting as a personal knowledge base.

It is a desktop application built with Tauri and Next.js. The project topics point to Markdown editing, WebDAV sync, retrieval augmented generation, MCP and agent features, and the README describes configurable model settings with an OpenAI-compatible interface for conversations, note organization, writing assistance, translation and summarization. Knowledge base features reference embeddings, reranking, OCR and speech.

NoteGen is licensed under GPL-3.0, and downloads, documentation, a business offering and community discussions are linked from the repository. Since it is a local app, you keep notes on your own machine and choose which model provider to connect, which suits people building a personal knowledge management system.

Anytype Desktop is the official desktop client for Anytype, a personal knowledge base for macOS, Windows and Linux. It lets you collect pages, tasks, wikis and journals and link them together, while keeping data stored locally and encrypted across your devices.

The client is built around composable blocks such as text, databases, kanban boards and calendars, and you can define your own Types to shape the data model. Storage is offline-first with optional peer-to-peer sync, and encryption relies on the any-sync protocol. It is an Electron application written in TypeScript, and it can be extended through a gRPC API and AI agents described in the repository.

Sign-in uses an Any-ID, and installers are published on the releases page and the download site. The code is published under the Any Source Available License 1.0 rather than a standard open-source licence, and the README includes instructions for building from source and updating the middleware.

Blinko is a card-style note-taking app with AI features, designed for people who want to capture fleeting ideas the moment they happen. It is self-hosted and puts privacy first, so your notes stay on a server you control. The interface is built with Next.js and React in TypeScript, backed by PostgreSQL.

Its AI-enhanced retrieval uses retrieval-augmented generation, so you can find notes by asking in natural language rather than remembering keywords. Notes use Markdown and the project is tagged for memos and notebooks. A live demo, official site, documentation and English and Chinese Telegram communities are linked from the README.

Blinko is licensed under GPL-3.0 and installed on your own server, typically with Docker. It suits individuals who want a private alternative to cloud note and memo apps and are comfortable connecting their own AI provider.

Memex is a browser extension from WorldBrain for curating, annotating and discussing valuable content and ideas on the web, whether you work as an individual, a team or a community. It is available as an extension for Chrome and Firefox and focuses on research and note-taking from the pages you read.

The repository topics emphasize annotations and full-text search, so saved pages and your highlights and notes can be found again later. The product's homepage also states that Memex exposes its dashboard actions through the Model Context Protocol (MCP), with a discovery manifest and a gateway that returns matching actions on demand, so AI tools can work with it.

The code is written in TypeScript and is public on GitHub, but the repository metadata does not give a license, so check the project terms before reuse. The extension runs inside your browser, and sharing and discussion features depend on the vendor's own services.

Eclaire is an open-source, privacy-focused AI assistant that works across your personal data: tasks, notes, documents, photos, bookmarks and more. It aims to be a complete product rather than a framework, assembling proven building blocks into something you can run on your own hardware with local models and local data storage. It targets people who want AI help with personal or sensitive information without using hosted services.

The README lists four ideas: self-hosting, unified data so the AI can see and connect everything in one place, AI-powered features such as content understanding, search, classification, OCR and automation, and open-source extensibility through APIs. It also has sections on selecting models, architecture and development.

The project carries two prominent warnings. It is pre-release and under active development, so breaking changes are expected and backups are advised. It must also not be exposed directly to the public internet, and the authors recommend placing it behind Tailscale, Cloudflare Tunnels or an authenticating reverse proxy. Eclaire is written in TypeScript and licensed under MIT.
