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.
Threadbound turns messy Slack threads into clean, structured docs in Notion.
Important decisions happen in Slack threads and then disappear the moment the conversation moves on, buried under sidetracked replies and a wall of ๐ reactions. Threadbound fixes that.
React to any message in a thread with a configured emoji, and Threadbound:
No manual write-ups. No "can someone document this." React, and the doc shows up in your team's Notion database, linked back to the original thread.
Free to start, with unlimited captures on paid plans.
Cryptee ThreadboundIndividuals 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.
Threadbound's answer:
General AI assistants inside Slack (like Notion's own Custom Agents or Atlassian Rovo) are built to answer questions and search your workspace on demand. Threadbound does one thing specifically: turn a single thread into a permanent, structured record the moment someone reacts to it, no prompting, no asking the AI a question, no separate workflow to remember. It's a single emoji react, not a tool you have to learn.
Threadbound's answer:
Most Slack summarizer tools give you a paragraph. Threadbound gives you a document: a summary, the decisions that were made with the reasoning behind them (when it was actually stated in the thread), and any action items pulled out as checkboxes, published straight to Notion. It's also built for reliability rather than just a single API call, if one model returns a malformed or low-quality result, it automatically retries or falls back to another model rather than publishing something broken.
Threadbound's answer:
Small to mid-sized teams, mostly engineering and product teams, who already run Slack and Notion side by side and make a lot of decisions asynchronously in threads. It's built for teams that feel the pain of "wait, what did we actually decide?" a few times a week, not occasionally.
Threadbound's answer:
It started from a personal frustration: important decisions kept happening inside long Slack threads, and a week later nobody could reconstruct what had actually been agreed on, just an endless scroll and a pile of reactions. What began as a simple "summarize this thread" bot turned into a more serious project once it became clear that getting reliable, correctly-formatted output out of an LLM consistently is the actual hard part, not calling the API.
Threadbound's answer:
Next.js and TypeScript for the app, hosted on Vercel, with Supabase for the database and auth. It integrates with the Slack Web API and the Notion API, uses Stripe for billing, and the LLM layer is built on the Vercel AI SDK with support for multiple providers (Claude, Gemini, and others) so it isn't locked to a single model.

> 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: over 3 years ago
