Notta vs Rimo — meeting AI when the meetings are in Japanese
Notta and Rimo are the two names that come up for transcribing Japanese-language meetings. If your meetings are in Japanese, this is a real decision; if they are in English, use an English-first tool instead. Prices checked on each vendor's site, November 2026.

The short version
- A few meetings a month, personal notes, want to try it free → Notta (120 free minutes a month, 3 minutes per recording)
- Daily meetings, shared with a team and searched later → Rimo (unlimited bot recording and transcription)
- Company-wide with hours allocated per department → LINE WORKS AiNote
All three target Japanese-language meetings. What separates them from English-first tools is speaker separation when people talk over each other, and handling of proper nouns and internal terminology tuned for Japanese. Accuracy figures are vendor-published; no third party has compared them under identical conditions, so a trial on your own meeting audio is the only real test.
1. Price and limits
| Notta | Rimo | |
|---|---|---|
| Free plan | Yes — 120 min/mo, 3 min per recording, 1 account | Free trial (check current duration) |
| Individual paid | Premium JPY 1,185/mo (annual, incl. tax; JPY 14,220/yr) | Pro JPY 4,950/mo (incl. tax) |
| Individual limits | 1,800 min/mo, 5 hours per recording | Unlimited bot recording and transcription, 1,000 Rimo AI credits |
| Team | Business JPY 2,508/mo (annual, incl. tax; JPY 30,096/yr) | Team JPY 6,600/mo (incl. tax) |
2. The per-recording cap is the real constraint
You hit the per-recording limit long before the monthly total. Notta's free plan caps a single recording at three minutes, which is a microphone test, not a meeting — a thirty-minute call cannot be captured in one piece. Paid plans raise it to five hours, which covers normal meetings.
If you record long sessions, check whether a half-day workshop exceeds five hours. If it does, you are splitting recordings, every time, forever.
3. How each one captures the meeting
Rimo supports Zoom, Microsoft Teams, Google Meet and Webex with a bot that joins the call. Nobody has to start a recorder on their own machine, so meetings you did not organise still get captured — which also means you need a rule about telling participants a bot is present.
Notta records from web, desktop and mobile apps, so it also covers in-person meetings and field interviews. Being independent of the conferencing tool suits a mix of online and offline work.
Check these regardless of which you pick
- The procedure for telling participants they are being recorded, including external attendees
- Where transcripts are stored and for how long
- What happens to someone's recordings when their account is deactivated
4. Rolling it out company-wide
For a department or a whole company, LINE WORKS AiNote offers pooled transcription hours bought per environment: JPY 19,800/mo (annual contract; JPY 22,000 monthly) for 6,000 shared minutes, JPY 54,000/mo for 18,000 minutes, and JPY 162,000/mo for 60,000 minutes, with extra time from JPY 360.
Per head that costs more than an individual tool, but usage is managed as an organisational total rather than tied to named people. Once you account for finance processing and reassigning accounts every time someone changes role, the pooled model gets more attractive the larger the organisation.
Frequently asked questions
Which is more accurate?
Both target Japanese and both publish high figures, but there is no public third-party comparison under identical conditions. Results vary with the number of speakers, microphone quality and how much jargon is used. Trial both on your own audio.
Can the free plan carry real work?
Notta's free plan caps a recording at three minutes, so it cannot capture one ordinary meeting. Treat it as a functional check; production use starts on a paid plan.
Is recorded audio used for training?
It depends on the vendor's terms and your settings. For business use, confirm that there is an opt-out and whether it is on by default.
