Xentropy supports multiple capture modes. Each feeds into the same AI pipeline — transcribe, analyze, embed, connect — so no matter how you capture, the result is structured, searchable knowledge.

#

Voice is the primary capture mode. Designed for the "thinking professional" — founders, researchers, writers — who has more thoughts than time to organize them.

Key features:

  • One-tap record — open the app, tap the mic, speak
  • Stream-of-consciousness — ramble freely; the AI segments your monologue into atomic thoughts
  • Background processing — transcription (Whisper), summarization, tagging all happen asynchronously
  • Multi-platform — mobile app, lock-screen widget, share sheet

See the Voice Setup guide for platform-specific instructions.

#

The classic capture mode. Available on both web and mobile.

  • Free-form text with markdown support
  • Auto-saved as you type
  • AI enrichment happens after save (summary, tags, folder suggestion)

#

Capture whiteboards, documents, or anything visual.

  • Take a photo with the in-app camera
  • Upload from your gallery
  • Stored alongside text and voice notes in your Wall

Optical character recognition (OCR) for text extraction from images is on the roadmap.

#

Every capture flows through the same pipeline:

flowchart LR
  Capture --> Transcribe[Whisper Transcription]
  Transcribe --> Analyze[AI Analysis]
  Analyze --> Embed[Vector Embedding]
  Embed --> Graph[Knowledge Graph]
  Graph --> Wall[Your Wall]
  1. Transcribe — voice is converted to text via OpenAI Whisper
  2. Analyze — the content gets a summary, tags, sentiment, and entity extraction
  3. Embed — a vector embedding is created using text-embedding-3-small
  4. Connect — the capture is linked to related notes via pgvector similarity search
  5. Organize — a folder is suggested (AI suggests, you confirm — nothing is filed without your approval)

All processing happens in the background. Your Wall updates in real-time as each stage completes.
