Odin puts one layer over whatever is on your screen: live captions and translation from your computer's audio, an agent you can ask about what you're hearing and seeing, notes you can keep, and a learning mode for the words you keep meeting.

What you can do

• Live captions & translation. Odin listens to the audio your computer is playing, meetings, videos, lectures, streams, games, and shows source and translated lines on a click-through overlay above your other windows. Live speech recognition and translation cover 60+ languages.
• Ask the Odin agent. With push-to-talk (Ctrl+Shift+Q) or a typed question, ask about what you just heard. The agent uses the recent transcript, and a screenshot when it helps, so questions like "what did they just decide?" or "summarize the last few minutes" work without leaving the app you're in.
• Keep notes. Summaries, explanations, and next steps come back as answers you can keep. Your session transcript exports as .txt, .srt, or .json, and the agent history exports as .json or .md.
• Learning mode (Pro). Open peek mode on the overlay, tap a word in a settled caption line, and see its meaning in your language. Keep it, and it goes into your own word deck to review later with a short spaced repetition pass. You can replay the moment a word came from while captions are running.

How it works

On Windows, Odin captures system audio directly rather than a single browser tab, so anything your computer plays can be captioned. Audio is transcribed as you listen; translation happens on the same low-latency stream. Subtitles, agent answers, and learning prompts all render on one overlay that stays above your apps and lets clicks pass through to whatever is underneath.

When you're signed in, speech, translation, and agent requests run through Odin's hosted cloud, there are no API keys to configure. Developers can instead run with their own provider keys (ODIN_BYOK=true). Voice commands use the system dictation service, while media translation uses the Soniox real-time stream.

Platforms and requirements

• Windows 10/11: fully supported.
• Android: available.
• macOS: preview; requires a virtual audio device for loopback.
• iOS: on the waitlist.
• A microphone is only needed for voice questions, the wake phrase, and voice commands. Captions and the agent work without one.
• An internet connection is required for hosted cloud features.

Keyboard shortcuts

• Ctrl+Shift+S, start or stop captions
• Ctrl+Shift+Q, ask the Odin agent (hold to talk)
• Ctrl+Shift+O, show or hide the overlay
• Ctrl+Shift+L, peek mode, to tap words for meanings (Esc exits)

Plans and usage limits

Cloud capture time and Odin agent usage are metered per calendar month and reset on the 1st. Your live usage is always visible in the app under Account.

Pro gives you 5× the usage of Basic: 50 hours of capture instead of 10, and five times the Odin agent usage, plus learning mode and priority support.

Learning mode is part of Pro. Local transcription and the features that don't reach a cloud provider aren't metered.

Billing

• Basic starts with a 7-day trial, then $5.99/month or $64.69/year. A payment method is required at checkout, and the first charge happens when the trial ends unless you cancel.
• Pro is $15.99/month or $153.50/year, and starts immediately without a trial.
• Annual billing is billed up front for 12 months and saves up to 20% against paying monthly.
• You can change your billing period or cancel from your Odin account. Cancelling stops future renewals; your current paid period continues to the end.

Privacy and data

Odin does not store your audio, transcripts, or translations on Odin servers. When you use cloud features, speech and text are processed by third-party providers and pass through. Optional usage telemetry (counts, not transcript text) can be turned off with ODIN_TELEMETRY=0. See the privacy policy for the full detail.

If something isn't working

• No captions appear. Check that playback is actually running, then confirm the plan has capture time left under Account. Some protected content and platform-restricted audio can't be captured.
• Captions feel slow or the app is heavy. Local transcription runs on your own machine and is much slower than the hosted streaming backend. Switching the transcription backend to the cloud option is the usual fix.
• No sound in a call or game is captured. Odin captures what the system is playing; audio routed to an exclusive or protected device may not be visible to it.
