Rammenta logo

Rammenta.com

A memory layer for your life and work.

A native iOS, watchOS, and macOS app that turns talk into memory: record or import any conversation and instantly get a clean, speaker-labeled transcript with an AI summary, action items, and the moments that matter, then ask questions across everything you've captured. Every model runs on the user's own device, fully offline; their data never leaves their device.

  • Full on-device speech-AI stack: designed and built the entire pipeline to run locally in Core ML: transcription (WhisperKit / Apple SpeechAnalyzer), speaker diarization (FluidAudio), and biometric voiceprint identity (ECAPA-TDNN), with no servers, no external APIs, and no per-use cost.
  • Private, instant search and insight: on-device vector search and RAG over the user's entire memory layer (local embeddings + sqlite-vec), with summaries, action items, and decision points generated by Apple Foundation Models, zero cloud dependency; works offline.
  • The architecture advantage: a custom-built stack where every AI layer runs on the device erases cloud cost and the privacy and compliance risk of sending sensitive content off device.
