5 Notta Alternatives Compared — Pricing, Data Policy, and Accuracy
Contents
Notta is widely used as a Japanese-capable AI meeting assistant, but more teams are looking for a Notta alternative — citing cost, data-storage concerns, and a desire for something simpler. This post compares five alternatives on three axes: data policy, pricing, and accuracy.
3 reasons people look for a Notta alternative
1. Concerns about data retention
With Notta, audio and text are stored in the cloud. Meeting content often includes sensitive material — strategic decisions, customer data, confidential discussions — and teams increasingly want to know exactly where that data lives and for how long. Security teams and ISMS-certified organizations need a clear, auditable answer to that question.
2. Pricing that adds up
Notta's business plans start at roughly ¥2,000 per user per month. Roll that out across a whole team and you're looking at hundreds of thousands of yen per year. Startups and mid-sized companies in particular keep asking the same question: is there a more cost-effective alternative?
3. Feature overload where simplicity is wanted
Notta is feature-rich, which isn't always what teams want. "I just need meeting minutes — why is the setup so complex?" and "most of the features don't apply to me" are common complaints. There's steady demand for a tool with a clean UI that does one job well.
5 alternatives — side-by-side comparison
The table below compares five of the most commonly considered Notta alternatives.
| Tool | Price | Data policy | Accuracy |
|---|---|---|---|
| Notta | From ¥2 | Stored in cloud | High |
| Kotonoha | From ¥980/mo | Data Zero (nothing retained) | High |
| tl;dv | Free – $25/mo | Stored in cloud | Fairly high |
| Rimo Voice | Pay-as-you-go (from ¥22/min) | Stored in cloud | High |
| AI GIJIROKU | From ¥1 | Stored in cloud | Moderate |
| CLOVA Note | Free (with limits) | Stored in cloud | Fairly high |
Among these, Kotonoha is the only option with a Data Zero policy. Because neither audio nor text is retained server-side after processing, the risk of data leakage is structurally eliminated rather than merely mitigated.
Why teams pick Kotonoha as their Notta alternative
Kotonoha is chosen as a Notta alternative especially by teams with strict security requirements. Three reasons stand out.
Data Zero policy
Audio and text are completely deleted from our servers once processing finishes. We never use your content for AI training. The core promise: you don't have to hand your data over in the first place.
Less than half of Notta's price
Plans start at ¥980/month. The cost gap widens as your team grows — saving teams hundreds of thousands of yen per year.
Simpler UI
Upload or record audio, and you're done. No complex settings to navigate. It's purpose-built for meeting minutes, without the feature bloat.
Frequently asked questions
Q. Can I migrate my past meeting data from Notta to Kotonoha?
A. Because Kotonoha doesn't retain data, there's no import path for historical minutes. What you can do is export your text files from Notta and keep them locally — then start using Kotonoha for new meetings going forward.
Q. How does transcription accuracy compare to Notta?
A. Kotonoha uses a high-accuracy speech-recognition AI, and for Japanese its accuracy is on par with or better than Notta. Speaker-diarization accuracy in particular is strong even in meetings with multiple overlapping speakers.
Q. Is there a free tier?
A. Yes. Kotonoha offers a free plan — no credit card required. You can sign up and start using it immediately, so the best way to evaluate accuracy is to try it on your own meeting audio.
Q. Does Kotonoha support real-time transcription like Notta does?
A. Yes. Kotonoha supports real-time recording and transcription directly in the browser, and it also accepts uploaded audio files — so you can pick whichever fits the use case.
Q. With Data Zero, can I still revisit past minutes?
A. Yes — the generated minutes can be downloaded directly from the browser as text or PDF. Data Zero only means we don't retain anything server-side; you're free to save and re-read anything locally.
