Text Shortcuts

Say less, type more

Create trigger abbreviations that expand into full text blocks, activated by voice or keyboard. Just say "slash soap" during dictation and get a complete SOAP note template, or type the trigger directly. Built-in macros insert today's date, time, and clipboard contents automatically.

Voice or keyboard triggers, say "slash sig" or type /sig to expand full text blocks instantly
Dynamic macros, %date%, %time%, %day%, %clipboard% resolve at expansion time
Unlimited snippets, create as many shortcuts as you need, organized by category
Import & export, share snippet libraries as JSON, or import from colleagues
Built-in text shortcuts, no extra subscription needed

Data Protection

Tamper-evident audit log. A chained record of every transcription.

Every transcription is recorded in a chained audit trail. Entries are linked with SHA-256 checksums, which makes edits to past entries detectable. Export the full log as JSON for compliance reviews.

SHA-256 hash chain, each entry's checksum includes the previous entry, making the log tamper-evident
Design assertion, each entry carries the app's no-outbound design assertion for the transcription path
Full metadata, engine used, model path, audio duration, word count, OS version, app version, timestamp
JSON and CSV export, one-click export for compliance reviews and internal audits
Chain verification, built-in integrity check validates the linkage of the recorded entries
Encrypted backup & restore, create encrypted backups of your transcription database and restore on any device, keeping your data safe and portable
