Cryptee is a safety and privacy focused, encrypted and cross-platform personal data storage service. You can write personal documents, notes, journals, store photos and all sorts of other files.
It works on all your devices and provides a zero-knowledge place to keep all your sensitive digital belongings. cryptee has all the features you'd expect from a modern document editor, like live sync with unlimited devices, rich document editing, to-dos, markdown, hotkeys, code highlighting, latex math, embeds, attachments, support for tables, ability to attach pdf files, read EPUB ebooks, listen to audio-memos, as well as open and link other various file formats.
Cryptee is based in Europe, in Tallinn, Estonia. A country named "the most advanced digital society in the world" by Wired, and a country where the government runs on blockchain.
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.
Cryptee
ContextForge.devIndividuals or organizations that require secure storage and privacy for their documents and photos, particularly those concerned about data tracking, surveillance, or needing a privacy-first cloud service alternative.
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.

> The only major hurdle to this is Apple continuing to treat web apps as second class citizens on iOS If you add a site to iOS' homescreen it automatically becomes a PWA. The best example I found of a site fully leveraging this feature is Cryptee[0]. They talk about the PWA thing here: https://crypt.ee/download [0] https://crypt.ee/. - Source: Hacker News / over 2 years ago
Well, then - if self hosting is not your thing - something like crypt.ee might be your thing? Clearly a different pricing model, data is fully encrypted, open source, across platforms. Source: over 2 years ago
Https://crypt.ee now. I used to mostly use local markdown editors like Ulysses and Zettlr. Source: about 3 years ago
Crypt.ee Ticks 1/2/3/5 of your requirements However free tier only has 100MB storage which might be enough for a journal, it also has the best rich text editor of them all, would highly recommend. Source: about 3 years ago
I've only used it for editing docs but have found crypt.ee very easy to use. Source: about 3 years ago
