Which Is Easier to Carry?

How Do the Buttons Work on Each Recorder?

Comu Action Pro has a record key and an AI key, and Comu Note Pro has one record key.

On Comu Action Pro:

1. Power on. Hold the record key for 3 seconds. The screen lights, the device vibrates and a pairing QR code appears.
2. Pair. Pair by Bluetooth in the Comu app.
3. Start. Hold the record key for 2 seconds. The device vibrates once, shows a recording animation and starts the timer.
4. Pause or resume. Single press the record key.
5. Stop. Hold the record key for 2 seconds. The device vibrates twice and the screen shows "Saved".

On Comu Note Pro, one press of the record key starts a recording and one press stops it.

Both recorders reset the same way if you hold the record key for 12 seconds. Comu Action Pro also has a reset hole on the side that you press with a pin.

Which Comu Recorder Records Phone Calls?

Comu Action Pro records phone calls with its built-in bone-conduction microphone: you hold the device against the phone to record the call.

The Comu app recognizes call mode and face-to-face mode and enhances the voice for each.

For Comu Note Pro, the microphone specification is two MEMS microphones and one VPU (bone conduction) sensor.

Recording rules for calls and conversations differ by place, so read Is an AI Note Taker Legal? before you record other people.

What Does the AI Key on Comu Action Pro Do?

The AI key on Comu Action Pro lets you speak a request to Comu AI: press and hold the key, say what you need, and review the result in the Comu app.

The screen shows the steps: AI Listening, then Task Sending, then Task Sent Successfully. Example requests:

• "Summarize this meeting and list the action items."
• "Write a follow-up email for the client."
• "Turn this product discussion into a presentation."

The AI key needs the recording synced to the app and an online connection for AI processing. Review the generated work before you use it. Creating an email draft does not send the email.

Comu Action Pro also marks key moments in a recording: double-tap the body or press the AI key. A three-axis accelerometer detects the double tap, and you switch the double-tap marking on in the Comu app. Double-tap marking is available on Comu Action Pro only.

Do Both Recorders Use the Same App and Comu AI?

Both recorders use the same Comu app and the same Comu AI. The same abilities run on both devices, and Comu Action Pro adds the AI key and double-tap marking from its hardware.

Every order of either device includes the Starter plan, which is $0 and needs no subscription. Starter includes unlimited real-time AI transcription, unlimited basic summaries, 113 languages, speaker recognition, Actions, the Comu AI assistant, AI slides, docs and email drafts, unlimited custom summary and PPT templates and standard AI models. On Starter you tap to transcribe and summarize a recording; Premium and Elite do it automatically.

Starter allows real-time translation 1 time per month and Deep Dive Suite 3 times per month. Premium and Elite add the following (US app prices, checked Nov 13, 2026):

You subscribe to Premium or Elite only inside the Comu app, through the Apple App Store or Google Play. You can subscribe in the Comu app without buying hardware and upload audio files; MP4 up to 500 MB.

Let Comu AI Turn Recordings Into Work on Both

Comu AI turns a recording from either recorder into a transcript, a summary and follow-up work, and each output below is in the plan that ships with the device unless the entry names Premium or Elite.

• Transcript and playback. The transcript highlights in sync with the audio. Playback runs from 0.75x to 2.0x, with 15-second jumps back and forward and a waveform.
• Speaker identification. Comu automatically separates and labels speakers. The labels sit beside the transcript and the audio on every plan.
• Summaries. Comu matches a summary template automatically or uses the one you pick. There are 30+ built-in templates, including general, insurance, sales, real estate, medical, legal, journalist, wealth management, headhunter and manager, and custom summary templates are unlimited. Summaries are editable, and you can re-transcribe, re-summarize and re-analyze a recording.
• Actions. Comu extracts to-dos from a recording with the owner, decision, deadline and next step. You can add actions by hand, and Comu proactively pushes the meeting summary and to-dos after a meeting.
• AI Slides. After a recording, Comu offers Generate Slides. You choose the audience, tone and page count, and the output is an editable PPT draft.
• AI Docs and AI Email. Comu writes Word, Markdown or PDF documents, and drafts a follow-up email with the recipient, subject, summary, decisions, action items and deadlines.
• Search and folders. Search past conversations by keyword, or ask the Comu chat page a question across recordings, files, contacts, Actions and history. AI organizes recordings into smart folders.
• Connectors. Gmail and Outlook for email, Google Calendar and Outlook Calendar, Google Tasks and Microsoft To Do, Slack and Zapier.
• Meeting Prep (Premium and Elite). When a recording names the next meeting, Comu builds a pre-meeting brief and reminds you before it.
• Moments (Premium and Elite, Beta). Comu turns the day's transcribed recordings into an event timeline and a daily diary.

AI-generated results are intended to assist you and may need your review and adjustment before final use.

What Does Each Setup Cost Over 1 and 2 Years?

Comu Note Pro with the Starter plan costs $128.99 over one year and over two years, and Comu Action Pro with Starter costs $169.99 over the same periods (Comu US store, Nov 13, 2026).

The Starter rows cover the plan that ships with the device: unlimited real-time transcription, speaker identification, basic summaries and 113 languages, where you tap to transcribe and summarize. The Premium and Elite rows add the yearly plan price to the device price and cover automatic transcription and summaries plus the other items in the plan table above. This is an arithmetic example at the Nov 13, 2026 prices: the device sale price plus the yearly plan price multiplied by the number of years the plan runs, computed by script.

The arithmetic: Comu Action Pro with Premium billed yearly is $169.99 plus $119.99 for one year, and $169.99 plus $239.98 for two. Comu Note Pro with Elite billed yearly is $128.99 plus $359.99 for one year, and $128.99 plus $719.98 for two.

At every plan level, the gap between the two recorders is the $41.00 device price difference of Nov 13, 2026, because Starter, Premium and Elite cost the same on both recorders.

Adding ComuCare to the device price gives these totals (arithmetic example, computed by script): Comu Action Pro with ComuCare is $241.98 for one year and $278.98 for two, and Comu Note Pro with ComuCare is $178.98 for one year and $208.98 for two.

Action Pro or Note Pro: Which Should You Buy?

Buy Comu Action Pro if you want the AI key, phone-call recording, the longer battery or the six-microphone array. Buy Comu Note Pro if you want the thinner and lighter recorder at the lower price.

Two things stay the same whichever you choose. You can start on the Starter plan that ships with the device and move to Premium or Elite later inside the Comu app. And both recorders sync to the same Comu app and use the same transcription, speaker identification and summary pipeline.

Is Your Data Treated the Same on Both?

The Comu app and account that both recorders use carry the same privacy commitments.

• Compliance. Comu is GDPR, HIPAA and SOC 2 compliant (checked Nov 13, 2026), and follows CCPA.
• Encryption. Files are encrypted throughout. Comu's Trust Center states that customer data is encrypted in transit and at rest, with AES-256 for data at rest and TLS 1.2 or 1.3 in transit.
• No data sale. "We never sell data to third parties."
• No AI training. "User data is never used to train AI models, nor shared for advertising or profiling purposes."
• Delete anytime. You can delete a single recording, a contact or the whole account in the app. Deleting a recording removes its text with it, and deleting the account removes all associated data from Comu's servers.
• App protection. An app lock works with Face ID, Touch ID or the screen passcode.
• AI processing. Audio is sent securely to AI service providers only to deliver the function you request, such as transcription or a summary.
• Where data lives. Comu runs in Amazon Web Services data centers in the USA. Recordings are stored in the cloud when Cloud Backup is on, and otherwise stay in the app or on the device, while notes are stored in the cloud.

Under Comu's privacy policy, when you use voice features you represent that you have obtained any consent needed from the people whose voices are recorded.
