From spoken word to a defensible record — secure transcription locally on your computer

memozero turns your audio recordings into precise text using state-of-the-art AI. Simply load your file (e.g. an interview) and the software automatically generates a transcript with timestamps. Speakers are automatically distinguished, and filler words can be captured on request.

Data privacy is our highest priority — especially for professionals such as lawyers, psychologists, and researchers.

Desktop App (Windows/Mac): All processing happens 100% offline on your device. No audio or text data ever leaves your computer. This is ideal for confidential content.

Yes, you can try memozero free for 14 days with full access to all features. Simply download the desktop app to start transcribing right away.

• Unrestricted access: During the two-week trial, all features are available without limitations.
• No risk: The trial is completely free for both individuals and organisations; payment is only required after the 14 days if you choose to continue.

Yes, memozero includes automatic speaker diarisation. The tool detects when a different person is speaking and initially assigns placeholders like “Speaker A” and “Speaker B”.

You can rename these placeholders globally with a single click in the editor — for example, to “Interviewer” and “Witness”. Once you change a name, the label is automatically updated throughout the entire document.

With good audio quality, recognition accuracy typically reaches 98–99%. Our technology is very robust and handles accents and background noise remarkably well. If an error does occur (e.g. with unusual proper names), you can correct it instantly in the integrated editor.

After review, you can export your transcript in various formats for archiving or further processing:

• File formats: Export your text as a Microsoft Word file (.docx), plain text file (.txt), Markdown file (.md), or JSON format (.json).
• Customisation: You can choose whether the export should include additional details such as line numbers for easier citation or precise per-word timestamps for deeper analysis.

memozero provides an integrated editor with a review function that lets you refine your transcript quickly and precisely.

• Synchronised audio player: As the audio plays, the corresponding words are highlighted in the text, so you always know exactly where you are.
• Easy editing: When you spot an error, simply click on the word or punctuation to correct it on the spot.
• Smart error detection: Words with low recognition confidence are automatically flagged. Click the marker and the player jumps two seconds before the passage so you can verify it immediately.

memozero is deliberately built as a desktop application for Windows and macOS — not as a cloud service.

• 100% local processing: Audio files and transcripts never leave your computer at any point. This eliminates the risk of data leaks, simplifies compliance (no data processing agreement required), and makes memozero suitable even for confidential or privileged material.
• No server-side quotas: Audio length and number of files are limited only by your hardware — no minute packages, no upload caps.
• Full use of your hardware: memozero leverages Apple Silicon (M1/M2/M3) or modern Windows GPUs directly. On capable machines often faster than a typical cloud workflow including upload and download.
• Works offline: Fully functional without an internet connection — e.g. in court, in the field, or in high-security environments.

The desktop app runs on current Windows 10/11 PCs and on macOS. For Mac users, we recommend devices with Apple Silicon chips (M1/M2/M3), as these perform transcription particularly fast and energy-efficiently. The app also runs smoothly on capable Windows machines (ideally with a dedicated GPU).

The technology behind memozero is extremely robust and typically handles regional accents very well.

• Heavy accents: With very strong regional dialects, accuracy may decrease since fewer AI training examples exist for these specific cases.
• Synced editor: Since text and audio run in sync in the editor, any remaining uncertainties can be corrected manually in no time.
