Voice notes
have become
the new evidence.
Cellebrite and Magnet get the data off the phone. Voxnote turns the voice notes, cross-app conversations, and AI findings into court-ready evidence locally, on your hardware, with every claim traced back to its source.
A working interactive demo is available. We respond within one working day.

Voice notes have outgrown the toolchain
A two-minute voice note costs 15–20 min of analyst time. Cases have 30+ of them.
The Voxnote demo runs a synthetic case end-to-end voice transcripts, cross-app threading, AI findings, audit trail, compliance pack. Five minutes of self-guided exploration. No login required.
A two-minute voice note costs 15–20 minutes of analyst time to properly review, transcribe, cite, and cross-reference. Under deadline pressure, some voice notes don't get listened to at all.
The forensic technology that gets the data off the phone is excellent. The layer that turns that data into evidence has not kept up.
A purpose-built analysis layer
Voxnote consumes the extractions you're already producing Cellebrite UFDR, Magnet AXIOM Portable Cases and gives the examiner a working environment built around three things the existing toolchain isn't built for.
Voice-first analysis
Codec-aware ingest from the four major messaging apps. Speaker diarisation. Confidence-scored transcription. Semantic search across audio. Voice notes threaded into the surrounding text conversation.
Local-only inference
No cloud APIs. Llama-class language model, Whisper-class transcription, multilingual embeddings all running on the customer's own hardware. The evidence never leaves the network.
Compliance as substrate
Every artefact content-hashed. Every transformation logged with model version. Every analyst action recorded in a tamper-evident chain. ISO 17025, EU AI Act and CPIA-aligned compliance pack exported with one click.
We complement Cellebrite and Magnet. We don't compete with them.
Three forces converging in 2026
Three forces are converging in 2026.
Voice has overtaken text.
Among under-35s, voice notes have substantially displaced typed messages for sensitive communication. The evidentially decisive moments are increasingly in audio.
Local AI is finally good enough.
Open-weight models Llama 3.3, Whisper-large-v3, BGE-M3 running on a single GPU now match cloud-API quality. Sovereign deployment is no longer a quality compromise.
UK regulation has shifted.
Post-Horizon scrutiny of computer-derived evidence, the EU AI Act's high-risk obligations, and the statutory FSR all push toward provable AI tooling. Opaque tools are becoming a procurement blocker.
The window for a European-built sovereign analysis layer opens now.
