Comu vs HiDock: AI Voice Recorders Compared on Price, Calls and Plans

If you want a pocket recorder with live transcription and no minute cap on the plan that comes with it, skip to Comu Action Pro and Comu AI. If your question is price, skip to the 1-year and 2-year costs. If your question is phone calls, skip to how each records them.

How do Comu and HiDock compare at a glance?

Comu sells two pocket recorders that sync to one app, and HiDock sells a family of recorders and docks that sync to its HiNotes software. The table compares the two Comu recorders with the two HiDock pocket models (prices from each vendor's US store on Nov 13, 2026).

HiDock also sells the P1 mini, a smaller plug-in recorder for phones with two recording modes (Call Mode and Room Mode) and a 768 kbps maximum recording rate. HiDock P1 mini costs $119.00, or $99.00 in the cart with a $20 saving applied automatically (Nov 13, 2026).

What does each recorder cost over 1 and 2 years?

The device prices are $169.99 for Comu Action Pro, $128.99 for Comu Note Pro and $199.00 for HiDock P1, so Comu Action Pro is $29.01 below HiDock P1 and Comu Note Pro is $70.01 below it before any plan. The plan decides the rest of the bill, and each vendor's plan covers a different set of features.

What the Comu numbers cover: the Starter plan that comes with the device includes unlimited real-time transcription, speaker identification, basic summaries and 113 languages, with no subscription required. HiDock's free Member plan includes unlimited basic transcription and summaries plus 300 Pro trial minutes a month, and live transcription and speaker identification belong to HiDock's Pro Membership, which you buy as minutes (Pro) or as an annual plan (Unlimited). Because those two features are in Comu Starter, the table compares Comu Starter with HiDock's Unlimited plan. The totals are an arithmetic example computed by script: device price plus plan price over the full period, from the prices on Nov 13, 2026.

Over one year, Comu Action Pro costs $228.01 less than HiDock P1 with Unlimited and Comu Note Pro costs $269.01 less. Over two years, the gaps are $427.01 and $468.01.

HiDock's Pro tier is sold by the minute, so its cost depends on how much you transcribe rather than on a period. Pro costs $12.99 for 1,200 minutes (20 hours) or $99.99 for 12,000 minutes (200 hours). The device plus each pack is an arithmetic example.

Comu's paid plans are optional. Premium costs $14.99 a month or $119.99 a year, and Elite costs $29.99 a month billed annually ($39.99 month to month). Premium and Elite add automatic transcription and summaries, unlimited real-time translation, custom vocabulary, Meeting Prep, Moments, advanced AI models and an open API, and you buy them inside the Comu app.

The Comu store prices are promotion prices shown on the Comu US store on Nov 13, 2026. Comu Action Pro is $169.99 against a regular price of $256.99, and Comu Note Pro is $128.99 against a regular price of $158.99.

How does each recorder handle phone calls and meetings?

Comu Action Pro records phone calls with its built-in bone-conduction microphone, which you hold against the phone. HiDock P1 records calls through paired Bluetooth earphones that it captures with its BlueCatch feature, and an ordinary telephone call goes on speakerphone with P1 in Room Mode.

On a computer, P1 connects by USB-C cable to the machine where the Zoom or Teams call happens, and you select HiDock P1 as microphone and speaker. P1 works with Teams, Zoom, Google Meet, Webex, WhatsApp and Slack, and it records in Room Mode and Whisper Mode without a phone or computer.

Comu Action Pro has six microphones, and Comu Note Pro has two MEMS microphones and one VPU bone-conduction sensor.

Recording rules differ by place: read Is an AI Note Taker Legal? before you record calls or meetings.

What do Comu's and HiDock's transcription plans include?

Both vendors ship a free plan with the device, and the two plans differ in what the free tier covers. The table lists each vendor's free plan and the paid tiers (US prices, Nov 13, 2026).

HiDock gives H1, H1E and P1 owners "lifetime free transcription" and requires no subscription for the basic service. HiDock's Member plan also includes 8 core summary templates, calendar integration and 300 Pro trial minutes each month for features such as speaker identification, which you claim in HiNotes under Profile and Plans.

On Comu Starter you tap to transcribe and summarize a recording that has synced from the device. Premium and Elite do it automatically.

HiDock P1 vs Comu: how do the specs differ?

Comu Action Pro has six microphones and records up to 70 hours, Comu Note Pro is 3.1 mm thick and 27.6 g, and HiDock P1 has a USB-C cable plug and a magnetic metal plate. The spec table puts the Comu devices first.

Comu Action Pro has a record key and an AI key, and Comu Note Pro has one record key. HiDock P1 has a wheel, a BlueCatch button and a touch-control cable. Each P1 recording is 4 hours at most. P1 works with macOS, Windows, iPhone 15 and later, and Android phones with OTG.

What happens after the recording in each app?

Both vendors turn a recording into a transcript and a summary in an app, and the apps differ in what comes next. HiNotes transcribes in 75 languages, summarizes with GPT, Claude and Gemini models, labels up to 10 voices on Pro, and connects Member accounts to Google Calendar and Microsoft Outlook. Pro and Unlimited add Notion, Google Docs and Microsoft OneNote.

The Comu app produces the following from the same recording on the Starter plan:

• Transcript with speaker labels. The transcript highlights in sync with the audio, plays at 0.75x to 2.0x and jumps 15 seconds back or forward.
• Basic summaries. Comu AI matches a built-in template (30+ for general use, sales, insurance, real estate, medical, legal, journalism and more) or uses a template you pick, and custom summary templates are unlimited on every plan.
• Actions. Comu extracts to-dos from a recording with owner, decision, deadline and next step, and pushes the meeting summary and to-dos after a meeting.
• AI slides, documents and email drafts. After a recording, Comu offers Generate Slides, writes documents and drafts a follow-up email. Creating an email draft does not send it.
• Search and smart folders. Search past conversations by keyword, and AI files recordings into smart folders.
• The Comu AI assistant. Ask it by text or voice. On Comu Action Pro, hold the AI key and say a request such as "Summarize this meeting and list the action items." and read the result in the Comu app.

Results depend on recording distance, noise, speaking style, network and language. AI output is an editable draft that you review before you use it.

The Comu app and Comu AI are the same on Comu Action Pro and Comu Note Pro. The differences between the two are hardware, and the Comu Action Pro vs Comu Note Pro comparison lists them.

Where does your audio go, and what about privacy?

Comu is GDPR, HIPAA and SOC 2 compliant (Nov 13, 2026), encrypts files, never sells data to third parties, never uses user data to train AI models, and lets you delete a single recording or the whole account at any time. Comu runs in Amazon Web Services data centers in the United States, and audio is sent securely to AI service providers only to deliver the function you requested, such as transcription or a summary.

HiDock's P1 FAQ states that recordings are stored locally on the device and are not automatically uploaded to the cloud, and that "End-to-end security is guaranteed by Microsoft Azure, with GDPR compliance". When you associate a P1 with HiNotes, you choose whether team members can access the device's recordings, and HiDock recommends disabling access for high-security needs.

Can you return either recorder?

Both vendors offer a 30-day return. Comu includes free shipping, a 30-day return window and a 60-day price guarantee, under which eligible buyers can request the difference if the same product drops in price on the official Comu store (Nov 13, 2026). HiDock gives a full refund within 30 days of receiving the package and ships free.
