Notta Free Plan
Notta can also be tried for free.
However, the free plan has limitations, such as a restricted number of file imports and download features. It's primarily for trial use, so to use it for serious transcription, you will need to subscribe to a paid plan.

There are five ways to register for a Notta account:
- Link with a Google account
- Link with an Apple account
- Link with a Microsoft account
- Log in with SSO (Single Sign-On)

For this guide, assuming transcription for company work, I registered by entering an email address.
Once you enter your email address, a verification code will be sent to your email.
Entering the verification code allows you to proceed with registration.
After registering, a survey screen will open (you can skip it without answering).
Once you complete the survey screen, the "Create New Workspace" screen will open.
Enter your workspace name and click "Next."
You will be asked, "How do you plan to use Notta?" Select whether you will transcribe as a team or individually.
The Notta dashboard will open.
With this, your registration for transcribing with Notta is complete.
2. Upload (Import) Files to Notta for Transcription
Now, let's upload (import) files to Notta for transcription.
To upload (import) files to Notta, click the "Import" button on the dashboard.
This will open the file upload screen.
Drag and drop the file you want to transcribe, or click the upload area to select the file.
Once you select a file, it will automatically upload.
Once the upload is complete, the transcription process will automatically begin.
3. Review Transcription Results
Now, let's review the transcription results.

In the "Recent Notes" section of the dashboard, you will see the name of the file you uploaded, like this:
Click to open the transcription results screen.
On the Notta transcription results screen, you can review the transcribed text and play back the original audio.
Downloading requires a paid plan subscription
Clicking the "Download" button in the top right corner of the transcription results screen,
will open the download screen as shown.
However, downloading transcription results as text requires a premium (paid plan) subscription.
If you need to save in formats other than text files, such as for video subtitle creation, a paid plan subscription is essential.
Notta offers a free trial plan
This completes the process of transcribing with Notta.
While we used Notta's free plan for this transcription, its features are limited, so a paid plan subscription is essential for serious use.
Notta also has a real-time transcription feature, so if you're interested, it's recommended to check their official help documentation.
For free transcription, 'Mojiokoshi-san' is also recommended!
While Notta allows you to convert audio and video to text, there are other recommended AI transcription tools available!
One such tool is the latest Japanese transcription service, 'Mojiokoshi-san'.
