Continuity Band
Pick up exactly where you left off.|
Your workspace lives in plain-text files on storage you already control. Point the iPhone app at the same Dropbox or Files location your desktop uses, and every note, folder, and connection is right there waiting for you.
No proprietary cloud. No lock-in. No "sync" button to chase. Your knowledge simply moves with you because the files were always yours.

See the connections
Explore your knowledge graph with touch. Pinch, pan, and tap through the relationships between your ideas.
Ask your notes
AI chat answers questions grounded in your own documents, with the source notes shown right beside the reply.
Private by design
Local-first storage with optional QEncrypt encryption keeps sensitive notes protected, even if your phone never is.
Yours to keep
Portable plain-text files mean your knowledge is never trapped inside an app. Export, move, or back up freely.
Privacy Spotlight
Your phone travels. Your data shouldn't leak.|
Phones get lost, borrowed, and left on tables. That is exactly why Socratus is built local-first. Your notes stay on your device and in storage you choose, never funneled through a company server you cannot see.
For the notes that matter most, file-level encryption powered by QEncrypt adds a quantum-safe layer of protection, with clear visual indicators for anything that is locked.

Finally, my notes talk to each other
"I have years of research scattered across hundreds of files. Socratus surfaces connections I'd completely forgotten about, and the meaning-based search finds the right note even when I can't remember what I called it. Having all of it on my phone changed how I work."
Maya R
PHD researcher
Capture now, organize never
"I get my best ideas away from my desk. The Today's Note scratchpad is one tap from my lock screen, so nothing slips away anymore. By the time I'm back at my laptop it's all already there in the same workspace."
Daniel K
Writer
The graph is the killer feature
"Seeing my knowledge as a visual network instead of a folder list made everything click. I explore it on my phone between meetings and constantly rediscover old work that's suddenly relevant again."
Priya S
Independent consultant
Local-first is why I trust it
"Most note apps want my data on their servers. Socratus keeps everything in plain-text files I actually own, and the encryption on sensitive notes gives me real peace of mind carrying it all on a phone."
