▚ xentropy

Xentropy works on your phone. Whether you're capturing a quick thought on the go, browsing your knowledge graph, or chatting with AI, the mobile experience is designed for one-handed use.

Availability: The mobile web app works in any browser on iOS 16+ and Android 12+. A native mobile app is in development.

#

Open xentropy.ai in your mobile browser. Sign in with your account — the interface adapts to your screen size automatically.

#

  • Tap the mic to start a voice capture (requires browser microphone permission)
  • Tap the compose button (bottom center) to capture text or a photo
  • Swipe down on the Wall to refresh
  • Long-press a note for quick actions (copy, share, delete)

#

#

The fastest way to capture on mobile:

  1. Tap the microphone button at the bottom of the screen
  2. Speak naturally — a sentence or a five-minute ramble
  3. Stop recording — voice is processed asynchronously

Your voice note is transcribed (Whisper), summarized, tagged, and linked into your knowledge graph automatically.

#

  1. Tap the compose button (bottom center)
  2. Select Text or Photo tab
  3. Type your thought or take/choose a photo
  4. Hit Save

No title, no folder — just the thought. The AI does the rest.

#

Share content from any app — Safari, Notes, Twitter, LinkedIn — directly into Xentropy via the system share sheet.

#

Ask your AI anything about your captured knowledge:

  • Tap the chat icon (bottom navigation) to open AI Chat
  • Ask natural questions — "What did I note about project X?" or "Summarize my notes from this week"
  • AI searches your knowledge graph and returns answers with citations

#

  • The Wall shows your latest captures in reverse chronological order
  • Tap any note to see its AI analysis: summary, tags, related notes
  • The Graph view visualises connections between your notes

#

  • Mobile web uses the same encrypted connection as desktop
  • Voice recordings are processed server-side and not stored after transcription
  • Photo captures are stored and encrypted at rest
