Mydeas
Notes that stay in step on every device, even with more than one person editing.
- Live on the App Store
- iPhone
- Web
- Android
- Mac
Mydeas is a notes app with notebooks, nested tags, and a full editor for tables, task lists, and attachments. Notes sync to every device you use, and people you share with can edit the same note at the same time and see each other's changes as they happen. It works offline, keeps every note's history, and imports from Evernote and Notion. AI features are off until you turn them on.
What it does
- Capture it in seconds: share to Mydeas from any other app, or start a note from the home-screen widget.
- Organize and find: notebooks, tags that nest inside other tags, searches you can save and reuse, and backlinks that show which notes point at the one you're reading.
- Write real notes: headings, task lists with due dates, tables, code blocks, and photo, video, audio, and PDF attachments, plus camera scans whose text becomes searchable.
- Edit together, live: share a note or a whole notebook, see who else is in it, leave comments, and assign tasks.
- Remember the task: set a reminder on a task and have it show up on your Google Calendar as well.
- Keep working offline: edits are stored on the device and merge when you're back online, and the web app opens and works with no connection too.
- Leave any time: export any note as Markdown or HTML, or your whole account as one ZIP file, on any plan.
What we built
- An iPhone and Android app from one codebase, with the same editor as the web app.
- The web app, plus the public site at mydeasapp.com with its pricing, privacy, and terms pages.
- A sync server that merges edits from several people and devices without losing anyone's changes.
- An encrypted offline cache on the device, so notes open without a connection.
- A signed and notarized Mac app, released as a direct download from mydeasapp.com.
- Offline support in the web app, so it opens and keeps working with no connection.
- The API server, including a self-serve API and webhooks for people who want to connect other tools.
- Importers for Evernote and Notion exports, and full-account export.
- Subscription billing on the web, and an internal admin dashboard for accounts, usage, and service health.
- An opt-in AI feature that cleans up, summarizes, or edits one note at a time, and is off by default for every account.
The Mac app is a direct download from mydeasapp.com rather than the Mac App Store, and a Chrome web clipper is still in development. Notes are encrypted in transit; Mydeas is not end-to-end encrypted. Privacy Policy
