Comu vs OneMira C1 comes down to workflow. OneMira C1 is a $99 desk recorder that moves recordings to a Mac or Windows computer for local transcription with no subscription. Comu Note Pro ($128.99) and Comu Action Pro ($169.99) are pocket recorders that sync to the Comu app on your phone, with unlimited real-time transcription on the plan that comes with the device (checked Nov 13, 2026).
If you want to see how a pocket recorder and a phone app turn a conversation into notes, skip to Comu AI and the Comu recorders. If you only want the bill, skip to the 1-year and 2-year costs.

Pickup range and recording time on Comu devices vary with the environment and use. OneMira C1 voice pickup depends on distance, background noise, overlapping speech and room acoustics.
How does a recording become a transcript on each one?
On OneMira C1 a recording travels to a computer before it becomes text, and on Comu it travels to a phone app.
OneMira C1:
- Press the center button once to start recording. The turntable rotates while recording is active. Press once more to stop, or schedule a start and stop time.
- C1 records standalone onto 32 GB of onboard storage. No phone or computer connection is needed during recording.
- Back at your desk, reconnect C1 over Bluetooth 5.4 or USB-C to a Mac or Windows computer. C1 connects to one computer at a time.
- OneMira Desktop transcribes live or later, labels speakers locally and writes the AI notes. Desktop needs no OneMira account, and after the one-time software and model downloads it works offline.
Comu Action Pro:
- Hold the record key for 3 seconds to power on. The screen lights, the device vibrates and shows a pairing QR code, and you pair it by Bluetooth in the Comu app.
- Hold the record key for 2 seconds to start. One vibration and a recording animation confirm it. A single press pauses or resumes, and holding for 2 seconds stops and shows "Saved" on the screen.
- Recordings sync to the Comu app, where you read the transcript, summary and action items.
Comu Note Pro: one record key starts and stops a recording. Recordings transfer after the Bluetooth connection is made, in the background. Bluetooth is the default, and you can switch to Wi-Fi to speed up long recordings.
On the Starter plan that comes with the device, you tap to transcribe and summarize a recording. Real-time transcription in the app is unlimited on every Comu plan. Premium and Elite transcribe and summarize automatically when a recording syncs. You subscribe to either inside the Comu app.
The practical difference is where you finish the job. A C1 workflow ends on a computer that runs OneMira Desktop. A Comu workflow ends in a phone app that already holds your account, your recordings and the Comu AI assistant.
Which one records a room, and which records phone calls?
Both recorders pick up a table or a room, and Comu Action Pro adds a phone-call method built on its bone-conduction microphone. Recording rules differ by place, so tell people before you record (see Is an AI note taker legal?).
| Situation | Comu | OneMira C1 |
|---|---|---|
| Table or room recording | Comu Note Pro picks up to 5 m. Comu Action Pro picks up to 7 m with six microphones and adaptive pickup | 2 MEMS microphones with hardware noise cancellation, 5 m |
| Calls | Comu Action Pro has a built-in bone-conduction microphone: hold the device against the phone to record the call. The app recognizes call mode and face-to-face mode and enhances the voice | Computer calls and room recording |
| Continuous recording | Up to 45 hours (Comu Note Pro) or up to 70 hours (Comu Action Pro) | Up to 30 hours |
| Carrying it | 3.1 mm thick and 27.6 g (Comu Note Pro), 5.5 mm thick and 51.5 g (Comu Action Pro) | 20 mm thick and 85 g |
| Live text while people talk | Real-time transcription in the Comu app, unlimited on every plan | OneMira Desktop transcribes live or later on the computer |
OneMira C1 records calls on a computer: Zoom, Microsoft Teams, Google Meet and Slack Huddles on supported computers, with OneMira's documented setup. On a Mac, capturing the far end of a call needs macOS 14.2 or later and the Core Audio process-tap setup OneMira describes. OneMira says C1 does this without a meeting bot joining the call.
Comu Action Pro also lets you mark key moments while recording: double-tap the body or press the AI key, with double-tap marking switched on in the app.
How much do they cost over 1 and 2 years?
OneMira C1 costs $99.00, Comu Note Pro $128.99 and Comu Action Pro $169.99 as device prices. The Comu numbers in this section cover what the Starter plan that comes with the device does: unlimited real-time transcription, speaker identification, basic summaries and 113 languages, with a tap to transcribe and summarize. OneMira has no plan, so the table lists device prices only. Comu prices are store prices on the Comu US store on Nov 13, 2026: Comu Action Pro $169.99 (regular $256.99) and Comu Note Pro $128.99 (regular $158.99). OneMira C1 is $99.00 on its US product page on Nov 13, 2026.
| Setup | What you buy | 1-year total | 2-year total |
|---|---|---|---|
| Comu Note Pro | Device | $128.99 | $128.99 |
| Comu Action Pro | Device | $169.99 | $169.99 |
| OneMira C1 | Device | $99.00 | $99.00 |
Arithmetic example: Comu Note Pro at $128.99 is $29.99 above OneMira C1 at $99.00, and Comu Action Pro at $169.99 is $70.99 above it. Comu Action Pro is $41.00 above Comu Note Pro.
Optional paid plans change the Comu total. Premium costs $119.99 a year or $14.99 a month, and Elite costs $29.99 a month billed annually. You buy both inside the Comu app. Premium and Elite add automatic transcription and summaries, unlimited real-time translation, custom vocabulary, AI Meeting Prep, Moments (Beta) and advanced AI models. Starter includes real-time translation 1 time a month.
Arithmetic example: a Comu owner who adds Premium billed yearly pays $128.99 plus $119.99 = $248.98 in year one and $128.99 plus $239.98 = $368.97 over two years with Comu Note Pro. With Comu Action Pro the totals are $289.98 and $409.97.
Optional third-party AI services connected to C1, such as your own API keys for OpenAI, Anthropic or Gemini, have their own fees and limits.
Where do the audio and the notes go?
On OneMira C1 transcription runs on your computer, and on Comu recordings sync to the Comu app, where Comu processes them and encrypts them.
| Question | Comu | OneMira C1 |
|---|---|---|
| Where does transcription run? | In the Comu app: audio is sent securely to AI service providers solely to deliver the function you ask for, such as transcription and summaries | On the Mac or Windows computer, in OneMira Desktop, and offline after the one-time software and model downloads |
| Where do notes live? | In the Comu app. Recordings are stored in the cloud only when Cloud Backup is on, and notes are stored in the cloud | On your computer as open, editable Markdown files, never uploaded to a shared OneMira cloud workspace |
| Encryption | AES-256 for data at rest and TLS 1.2 or 1.3 in transit | Onboard storage on C1 is encrypted |
| Data handling | Comu never sells data to third parties, and user data is never used to train AI models | Voice activity detection and speech recognition run in the desktop app; raw audio chunks are temporary and the durable output is local text |
| Deleting data | Delete a single recording, a contact or the whole account in the app; the recording's text goes with it | You hold the files on your computer |
| Compliance statements | GDPR, HIPAA and SOC 2 compliant, and CCPA compliant (checked Nov 13, 2026) | FCC ID 2BXIX-C1 for the hardware |
Comu runs in Amazon Web Services data centers in the United States. You can lock the app with Face ID, Touch ID or the screen passcode.
What notes and AI tools does each one produce?
Both products turn a transcript into summaries and action items, and each adds its own tools around them.
OneMira C1 with OneMira Desktop produces:
- AI summaries, key decisions, meeting notes, action items, mind maps, briefs and reports, written by the built-in local AI.
- Markdown (.md) notes and a cross-meeting "Wiki" that connects past conversations and decisions.
- Optional model providers: your own API key for Google Gemini, OpenAI, Anthropic, DeepSeek, OpenRouter, or a local model through Ollama or LM Studio.
- Mira CLI and MCP, which let ChatGPT, Claude and Cursor work with your meeting context.
Comu produces, on the plan that comes with the device:
- Transcripts with speaker identification, summaries from 30+ built-in templates (or custom templates, unlimited) and Actions that extract to-dos with owner, decision, deadline and next step.
- Drafts made by Comu AI: slides, documents and follow-up emails.
- Search across past conversations by keyword, and AI smart folders that file recordings for you.
Is Comu a OneMira C1 alternative?
Yes, Comu is a OneMira C1 alternative built around a phone app instead of a computer. The two workflows differ in where you open your notes, where transcription runs and what you need on hand.
| Question | Comu workflow | OneMira C1 workflow |
|---|---|---|
| What opens your notes? | The Comu app on iOS or Android | OneMira Desktop on macOS 12 or later, or Windows 10 or 11 |
| How does a recording move? | Bluetooth sync to the app, in the background | Bluetooth 5.4 or USB-C to one computer at a time |
| When does transcription start? | In real time in the app, or by a tap on Starter after a device recording syncs; automatic on Premium and Elite | Live or later on the computer |
| What is the recurring cost? | None required | None |
| What do you ask the AI? | Comu AI in the app by text or voice; Comu Action Pro also by the AI key | Mira CLI and MCP, or the AI tools you connect |
| Phone calls | Comu Action Pro bone-conduction microphone against the phone | Computer calls on supported computers |
If your recordings end up in a phone app next to your contacts, calendar and email, the Comu path matches it.
How do returns, warranty and shipping compare?
Both vendors give 30 days to return a device and a one-year warranty, with different conditions. Terms are as of Nov 13, 2026. Comu also sells ComuCare: Comu Action Pro 1 year $71.99 or 2 years $108.99, Comu Note Pro 1 year $49.99 or 2 years $79.99, covering accidental damage, an extended warranty and one free replacement.

Let Comu AI Turn Pocket Recordings Into Notes
Comu pairs a pocket recorder with one phone app and one AI assistant, so a recording becomes a transcript, a summary, to-dos and drafts without leaving the app. Both Comu recorders use the same app and the same plans, and the plan that comes with the device does not require a subscription.
What the plan that comes with the device does (Starter, $0):
- Unlimited real-time transcription and unlimited basic summaries, with no subscription needed.
- Speaker identification that separates and labels speakers beside the transcript and audio. It is a software ability of the Comu app and works the same on both devices.
- 113 languages for transcription, real-time translation and summaries.
- Actions that pull to-dos from a recording and push the meeting summary and to-dos after a meeting.
- Comu AI assistant in the app by text or voice. It answers questions across your recordings, files, contacts, Actions and history.
- AI slides, documents and emails. After a recording, Comu offers "Generate Slides" with your choice of audience, tone and page count, and the output is an editable slide draft. Comu AI also writes documents and drafts follow-up emails with recipient, subject, summary, decisions, action items and deadlines. An email draft is not sent until you review and send it.
- 30+ built-in summary templates covering general, sales, insurance, real estate, medical, legal, journalist, wealth management, headhunter and manager use, plus unlimited custom templates.
- Standard AI models on Starter. Premium and Elite add advanced models.
The AI key on Comu Action Pro. Hold the AI key and speak a request, such as "Summarize this meeting and list the action items" or "Write a follow-up email for the client." The screen shows AI Listening, then Task Sending, then Task Sent Successfully, and you read the result in the Comu app. The recording must be synced to the app and the phone online for AI processing, and you review generated work before you use it.
Connectors. Comu connects to Gmail and Outlook for email, Google Calendar and Outlook Calendar, Google Tasks and Microsoft To Do, and Slack, where you talk to Comu with @Comu in channels or direct messages.
Phone calls. Comu Action Pro records phone calls with its bone-conduction microphone held against the phone.
Privacy. Comu is GDPR, HIPAA and SOC 2 compliant, encrypts data, never sells data to third parties, never uses user data to train AI models and lets you delete a single recording or your account in the app.
Prices. Comu Action Pro is $169.99 (regular $256.99) and Comu Note Pro is $128.99 (regular $158.99) on the Comu US store on Nov 13, 2026. Both ship with free shipping and a 30-day return.
