Heaper is an all-in-one workspace for your notes, files, and media. Link everything through tags and mentions. Add rich text notes to any file. Browse instantly offline, sync across devices, self-host if you want full control.
No noise. No tracking. No Lock-in.
The self-hosted server is free to use without storage limitations. Licenses become purchasable after the launch phase.
In Heaper, every file is a block with rich text notes. Add context to pictures. Attach deadlines, meeting notes, who sent it. Add journal entries to travel photos. Annotate PDFs with research notes. Track changes between versions, no more presentation_final_final.pptx.
Works offline. Syncs when you're ready. Your data lives where you do.
Connect everything through meaningful links — not rigid hierarchies.
All changes merge automatically — even from offline devices. No conflicts.
Run it on your own hardware. Control your world, end to end.
Heaper replaces folders with links. Tag links act as types or categories (browse them like folders). Mention links are references between ideas (bidirectional backlinks). You can browse by tag like a folder - but things can live in multiple places at once. It's how your mind actually works.
Don't plan categories upfront. Just add files and notes.
Link things when you see patterns. Check your "unlinked" view. Connect what matters.
Tags aren't categories you create — they're patterns you notice. Let structure emerge from use, not from planning.
Your mind doesn't file things away. It finds them through connections.
Most tools store your work on their servers and call it convenience. Heaper gives you back ownership. Every note, every file, every thought stays on your device - and syncs securely using modern merge-based technology. Self-host it if you like. Or use our encrypted cloud in Switzerland. Either way - your data is yours, not part of someone's business model.
Heaper doesn't hide behind AI tools that will maybe find your stuff. It is the tool you need to build your own system. It's fast, tactile, and honest. Every feature exists because it earned its place.
