Product limitations

Beta and compatibility

Synthezia is beta software. macOS 13.0 is a configured minimum, not a complete tested support matrix. The repository does not establish public support for every macOS configuration, Intel Mac, Linux, Windows, signing, notarization, or Gatekeeper behavior.

Generated content needs review

Transcription and AI-generated summaries or answers can be incomplete, inaccurate, or unsuitable for a particular decision. Review them against the recording and other authoritative sources. Synthezia does not currently offer a verified speaker-diarization or speaker-relabeling workflow.

Processing and privacy choices

Local Mode uses local models after their downloads complete. Selecting External API and explicitly authorizing its endpoint can transmit transcript, summary, prompt, conversation, and retrieved context to your configured provider. The application stores the remote-provider API key in macOS Keychain; embeddings remain local.

Storage and deletion limits

Deleting a session removes its encrypted database records, derived indexes, managed vault audio, and managed workspace files. It does not delete the original source file you selected or any export. Do not treat an application deletion as a complete filesystem-erasure guarantee for user-owned locations or external-provider copies.

Export limits

The supported structured-summary formats are Markdown, PDF, and DOCX. The current export flow does not provide general transcript or TXT export. The visible audio-copy action has inconsistent behavior across active and reloaded sessions and is not documented as a supported export contract.
