Meeting transcription has become a standard part of modern professional workflows. But the most popular tools — Otter.ai, Fireflies, Microsoft Copilot — all upload your audio to cloud servers. For confidential conversations, this creates real risk.
SecureThink transcribes audio entirely on your Mac. Your recordings never leave your device.
The Problem with Cloud Transcription
When you upload a recording to a cloud transcription service, the audio and resulting transcript are processed on servers you don't control. For many professional conversations, this is problematic:
- Legal client interviews — privilege and confidentiality obligations apply
- Medical consultations — PHI (Protected Health Information) must be handled carefully
- HR investigations — employee data must be processed lawfully
- Board meetings — commercially sensitive strategic discussions
- Therapy sessions — special category data under GDPR
Even services that claim to delete audio after processing leave an interval during which the data exists on their servers — and you have limited visibility into what happens during that window.
How SecureThink Handles Audio Locally
SecureThink uses on-device transcription powered by Whisper models running via Ollama. The workflow is entirely local:
- Import audio — drag and drop your MP3, M4A, or WAV file
- Local transcription — Whisper processes the audio on your Mac, no upload required
- Query the transcript — ask questions, extract summaries, search for specific statements
- Export results — copy outputs to your document management system
The audio file and transcript never leave your device at any point in this workflow.
Use Cases
Legal: Client Interviews and Depositions
Record consultations with clients, then transcribe and analyse locally. Extract key factual points, identify follow-up questions, or search the transcript for specific statements. Maintain full privilege protection throughout.
Medical: Clinical Consultations
Transcribe GP appointments, specialist consultations, or MDT meetings without uploading patient audio to any external service. Summarise key clinical points or extract medication information for record-keeping.
HR: Investigation Interviews
Record and transcribe disciplinary or grievance interviews. Keep sensitive employee data on-device throughout the investigation process.
Research: Qualitative Interviews
Transcribe research participant interviews without breaching ethical approval conditions that prohibit third-party data sharing.
Comparison: Cloud vs Local Transcription
| Feature | Cloud Transcription | SecureThink |
|---|---|---|
| Audio uploaded to remote server | Yes | No |
| Works offline | No | Yes |
| Third-party access to content | Yes | No |
| Query transcript with AI | Sometimes | Yes |
| Data retention you control | No | Yes |
After Transcription: AI-Powered Analysis
Once transcribed, SecureThink's RAG engine lets you query the transcript naturally:
- "Summarise the key points discussed"
- "Extract all action items and who they were assigned to"
- "Find every mention of [topic] and give me the context"
- "Flag any statements that appear contradictory"
All processing remains local. The AI never connects to an external service.
System Requirements
SecureThink requires macOS 15, Apple Silicon (M1/M2/M3) with 16GB+ RAM, and Ollama. The Standard licence is free for a single device.
