Use Case

Built for
secure environments.

If your environment has network restrictions, air-gaps, or strict data egress policies — Tellaflow is the only voice tool that passes.

Not "we promise to protect your data"

Most tools offer data protection policies. Tellaflow offers an architectural guarantee: your audio never reaches a server because there's no server to reach. There's nothing to intercept, subpoena, or breach.

Your audio never crosses a network boundary — architecturally impossible
No outbound DNS requests, no telemetry, no update pings while in use
Approved for use where other voice tools require exception requests
Compliant with environments that prohibit data egress to third parties
Security team can verify: there's no server endpoint to whitelist
Works inside a Faraday cage. We're not joking.

How Tellaflow compares

Otter, Whisper API, cloud tools
Audio sent to cloud server. Fails in air-gapped environments.
On-device but online
Requires internet for model updates or license checks. Blocked.
Tellaflow
Model runs on-device. Zero network activity. Works in any environment.

For IT and security teams: Tellaflow makes zero outbound network requests. You can verify this with any network monitor. There's no server endpoint, no license server, no telemetry host. Just an app that runs locally.
