Privacy and Power: How Offline Voice-to-Text Works

The short answer: press ⌃+⌥+R (Mac) or Ctrl+Alt+R (Windows/Linux) to record even without internet. AICHE stores recordings locally in an encrypted Later queue, then automatically processes them when you're back online.

Airport WiFi drops mid-dictation. Coffee shop internet dies. Your home connection goes down while you're capturing ideas. Losing recordings because of connectivity isn't acceptable.

1. Press your recording hotkey (⌃+⌥+R or Ctrl+Alt+R) as usual. AICHE detects no connection and activates Later mode automatically.
2. Record your thought normally (20-90 seconds). AICHE saves the audio to your local encrypted database.
3. See the Later panel showing queued items and storage used (typically 2-5 MB per minute of audio).

4. When internet returns, click "Process All" or let AICHE auto-sync in the background.
5. Each recording processes in 2-3 seconds, with real-time progress indicators for the queue.
6. All transcriptions appear in your History with original timestamps preserved.

Heads-up: Later recordings use AES-256 encryption but consume local disk space. A 10-minute recording uses approximately 20-50 MB. Check the Later panel's storage indicator if you record extensively offline.

The pro-tip: the Later queue is perfect for airplane work. Record 20-30 voice notes during a flight, land, connect to airport WiFi, and process the entire queue in under two minutes while walking to baggage claim.

How the Later Queue Works

When you press the hotkey without an internet connection, AICHE detects the lack of connectivity within milliseconds and activates Later mode. The recording proceeds identically to online mode - same audio quality, same duration limits, same hotkey controls. The only difference is what happens after you stop recording.

Instead of sending audio to servers for transcription, AICHE saves the compressed audio file to an encrypted local database. Each recording gets a timestamp and appears in the Later panel with a "Queued" status indicator. You can continue recording additional notes - each one stacks in the queue.

When internet returns, you have two options. Click "Process All" to transcribe every queued recording at once, or click individual recordings to process them selectively. Processing applies all your configured enhancements (Message Ready, Content Organization, Recognition Fix) just as if you'd recorded online.

When Offline Mode Activates

AICHE checks connectivity before each transcription attempt, not continuously. This means:

Complete offline. No WiFi, airplane mode, remote location - AICHE detects this instantly and queues everything to Later.

Intermittent connectivity. Subway, rural areas, congested conference WiFi - if the connection drops during a transcription attempt, AICHE automatically retries, then queues the recording if retries fail. No data is lost.

VPN or firewall blocks. Corporate networks that block AICHE's servers trigger the same behavior as no connectivity. The recording queues locally until you're on an unrestricted network.

Practical Scenarios

Airplane Work Sessions

Record voice notes during a 3-hour flight - ideas, meeting prep, email drafts, to-do items. A typical flight session produces 15-25 recordings using 30-75 MB of local storage. When you land and connect to WiFi, the entire queue processes in under 2 minutes. You walk off the plane with 15-25 polished text notes ready to paste into email, Slack, or documents.

Commuting Without Data

Train tunnels, subway systems, and rural stretches with no cell signal are prime dictation time. Record thoughts during connectivity gaps and let them process automatically when signal returns. AICHE handles the transition seamlessly - you don't need to manually switch modes or check connectivity status.

Remote and Outdoor Work

Hiking, camping trips, or working from a cabin without reliable internet. Capture ideas whenever they strike. The Later queue holds recordings indefinitely until you're back online - there's no expiration on queued items.

Conference and Event Notes

Large conferences often have overloaded WiFi. Record session takeaways, contact notes, and action items between talks without worrying about network reliability. Process everything in your hotel room at the end of the day.

Storage and Encryption

Later recordings are stored in an AES-256 encrypted SQLite database on your device. The encryption key is derived from your AICHE account credentials, meaning the audio files cannot be played by copying them off your device - they're unreadable without AICHE's decryption.

Storage usage depends on recording length and audio quality. A 60-second recording typically uses 2-5 MB. The Later panel displays total storage used, so you can monitor space consumption during extended offline sessions.

There's no limit to how many recordings you can queue, but available disk space is the practical constraint. On a device with 1 GB of free space, you can store roughly 200-500 one-minute recordings before needing to process or free space.

Result: you capture 15 ideas during a 2-hour train ride with spotty connectivity. When you reach WiFi, AICHE processes all 15 recordings in 45 seconds, giving you 15 polished text notes ready to use.

Do this now: turn off WiFi, press your hotkey, record a test message, and watch it save to Later. Reconnect and click "Process All" to see offline mode in action.
