Let's dive right into our recommendations for online transcription websites that you can use directly from your browser!
1. Mojiokoshi-san: Transcribe Audio, Video, Images, and PDFs with the Latest AI
'Mojiokoshi-san' is an all-in-one transcription website powered by the latest AI technology.
Leveraging rapidly advancing AI, it allows you to upload files directly from your browser and get highly accurate transcriptions in a short amount of time.
Another recommended feature is its ability to transcribe and extract text from various media files, not just audio.
- Audio: mp3, wav, wma, m4a, aifc, flac, aac, aiff
- Video: mp4, mov, avi, flv, mkv, webm, wmv, 3gp
- Images: jpg, jpeg, png, webp
- Documents: pdf
And many, many more file formats are supported.
Furthermore, it features two high-performance AI transcription engines, allowing you to choose the AI best suited for the content you're transcribing.
The two AI engines have the following characteristics:
- PerfectVoice: High-accuracy transcription, supports 100 languages
- AmiVoice: Speaker diarization (transcribes by speaker), specialized for Japanese
Of course, it also handles technical terms well and includes data management and search functions for your transcribed data.
If you're unsure about which transcription method to use, 'Mojiokoshi-san' can cover most of your transcription needs.
You can try it for free for up to 1 minute just by opening the website in your browser, no registration or login required. So, it's highly recommended to try 'Mojiokoshi-san' first!
2. Watson Speech to Text [Transcribing Recorded Audio (MP3)]
Watson Speech to Text is a website that supports transcribing audio files.
This tool is recommended if you want to transcribe audio data recorded with a voice recorder or similar device.
This is also an AI-powered transcription site, using the "Watson" AI engine developed by IBM in the United States.
Although the website is in English, the speech recognition itself fully supports Japanese.
Supported formats include major ones like MP3 and WAV, as well as increasingly common audio file formats such as FLAC, OGG, and WebM.
It's very convenient as it also supports files recorded with smartphone voice recorders.
While Google and Microsoft are well-known for their enterprise speech recognition AIs, IBM's Watson also has its unique strengths, so it's a good idea to try various tools depending on your data.
This site is a useful second option for when you really need it.
3. Sloos [Meeting Minutes Transcription]
Sloos is a transcription site specializing in creating meeting minutes, and it can also be used directly from your browser.
This service is recommended for automatically generating meeting minutes.
As a meeting minutes creation service, its "speaker diarization function" is particularly strong.
While 'Mojiokoshi-san' also has a speaker diarization feature, the accuracy of this site is quite impressive. It can identify multiple speakers with just one microphone, so you don't have to worry about confusion when reviewing audio later, wondering who said what.
The accuracy of its speech recognition is also quite good, allowing for precise transcription even in environments with some background noise.
This site is highly recommended for its strong performance in its specialized field, as it focuses specifically on meeting minute creation.
4. Otter [English Transcription]
If the audio language is English, this transcription site is highly recommended.
It features a proprietary AI speech recognition engine specialized for English, resulting in extremely high accuracy for English transcription. It also supports speaker identification, making it useful for meetings with international partners.
Although it's an overseas service, the paid plans for Japan are sold by NTT Docomo, so you can use it with confidence.
Most features are available in the free version, but there are some limitations (such as cloud storage and Zoom integration). For serious use,
If you wish to do so, you will need to subscribe to a paid plan.
5. Google Docs: Real-time Voice Typing
If you want to transcribe spoken content in real-time directly in your browser, the familiar Google Docs is a convenient option.
Even for those who use it daily for work, many might not know about the "voice typing feature" in Google Docs, or if they do, they haven't used it.
To use it, simply open Google Docs in your browser, turn on the feature, and click the microphone button.
You can even input symbols by voice, and it's available on smartphones and tablets via the browser version without needing to install an app.
However, it does have a weakness.
Google Docs' voice typing is primarily designed to recognize what is spoken in real-time.
It does not have a feature to transcribe pre-recorded audio files.
While it's possible to transcribe recorded data with some workarounds, it requires somewhat complex settings. Therefore, it's recommended to use other services like 'Mojiokoshi-san' if you need to transcribe audio files.
6 Benefits of Online Transcription Websites Accessible from Your Browser
So far, we've introduced recommended transcription websites that can be used directly from your browser. However, there are other transcription options available, such as installable applications or services where professional transcribers manually type out content.
What are the advantages of using online transcription websites?
1. No App Installation Required as It Works in Your Browser
The biggest feature of online transcription websites is that you can use them without installing any special applications, as long as you have a browser.
Many company-issued computers and smartphones prohibit unauthorized app installations, making these websites extremely useful in such situations.
Another benefit is that you can start using them immediately without the hassle of installing an app.
They are also perfect for minimalists who want to reduce the number of apps to save storage and keep their home screen tidy.
2. Usable Across Various Devices
The ability to easily use the same service on both your computer and smartphone is another reason to recommend online transcription websites accessed via a browser.
Paid apps and PC software often limit the number of devices on which they can be installed or used.
In contrast, with web-based services, you can use them from multiple devices simply by logging in with the same account.
Since they only require a browser to function, a key advantage is that they can be used regardless of the operating system (OS) of your computer (Windows/Mac) or smartphone (iPhone/Android).
3. Accessible from Anywhere
Another related benefit is that since you can access them with just a browser, the ability to perform transcription tasks from anywhere is significant.
Just as data stored in the cloud can be accessed from anywhere via a browser, using transcription websites allows you to easily:
- Upload and convert recorded data on the spot while out and about.
- Edit the content thoroughly on your computer once you return to the office.
This flexible design is perfectly suited for an era where remote work and nomadic work are increasingly common.
4. Easy Access to the Latest AI
Transcription tools accessible via a browser
The transcription websites use the latest AI for speech recognition.
In recent years, AI technology has advanced rapidly, and speech recognition used for transcription is a particularly practical field within AI. This means you can get very high-quality transcription results, comparable to manual typing.
While some automatic transcription apps require installation on your PC, running the latest AI demands very high performance. Therefore, services that you access via a web browser, where super high-spec computers connected via the internet handle the processing, offer significantly higher performance.
Another key point is that browser-based website services for transcription allow for faster feedback of rapidly evolving AI technology compared to installable apps.
Thus, if you want to use high-performance transcription, transcription websites are highly recommended.
5. Fast Transcription Speed
Transcription services accessed via a web browser are very fast because they use the latest AI for transcription.
For example, with 'Mojiokoshi-san', the two types of transcription AI available are:
- PerfectVoice: Can transcribe even tens of minutes of audio in about 10 minutes.
- AmiVoice: Can transcribe audio in roughly the same amount of time as the file length (e.g., 10 minutes for a 10-minute file).
This means transcription is completed in a very short time.
This is much faster than transcription apps installed on a computer, and certainly quicker than professional typist transcription services.
You might worry that such speed would compromise quality or lead to many errors, but that's not the case.
Transcription AI is highly capable, providing very high-quality transcriptions, including homonyms and specialized terminology.
If you're concerned, you can try a free transcription to test the accuracy yourself.
6. Affordable Pricing (Free Transcription Available!)
Furthermore, transcription services used via a web browser are very affordable.
While one-time purchase apps installed on a PC cost several thousand yen, and professional typist transcription services cost around 250-700 yen per minute, browser-based transcription services can be used for free to about 3,000 yen per month.
For example, Mojiokoshi-san offers free transcription for up to 1 minute (no account registration required).
As explained above, a major advantage of transcription websites, unlike one-time purchase apps or typist services, is that you can assess the quality of the transcription for free before paying.
Make the most of transcription websites by leveraging their free transcription capabilities.
6 Use Cases for Transcription Websites

AI transcription is still a relatively new type of tool, so some people might have this question.
While you might only think of uses like creating meeting minutes or interview transcripts, the evolution of speech recognition systems and the widespread availability of easy-to-use transcription tools have dramatically expanded their applications.
1. Remote Meeting Backup
One of the primary uses of AI transcription is "creating meeting minutes," but AI transcription allows individuals to keep a written record of meeting content.
During remote meetings, have you ever forgotten what was said?
Even if formal minutes aren't kept, like in large company meetings, you can personally record the audio as a backup and then transcribe it into text using a transcription website later, allowing you to review the content.
It's incredibly convenient because you can simply open it in your browser and start transcribing immediately, even if you suddenly need to transcribe meeting minutes.
2. Creating Lecture, Class, or Seminar Notes
Similar to meetings, for students' classes or work-related seminars, transcription websites make it easy to record content.
Again, you can complete the transcription simply by uploading the audio file to your browser right after the class.
There's no need for the hassle of taking notes by hand.
3. Writing Text by Voice Input
This method is recommended for those who are better at structuring their thoughts by speaking them aloud rather than typing on a keyboard.
By using the voice recognition function on your computer or smartphone to write, you can compose text smoothly.
4. Transcribing TV, Radio, and YouTube
It takes time to get information from TV, radio, and YouTube videos, doesn't it?
While "speed viewing" of videos, movies, and anime has become a hot topic, if you transcribe and read the content as text, you can input information even faster.
※Transcribing copyrighted material for personal use is generally fine, but refrain from uploading it to the internet or sending it to others without permission.
5. Brainstorming
AI transcription is also useful for brainstorming ideas.
Speaking is faster than writing, so by recording and then transcribing, you can record all your rapidly flowing ideas without interruption.
6. Reviewing English Conversation Lessons
Transcription websites can also be utilized when learning foreign languages, such as English conversation.
For example, you can record your English conversation lessons and then review them later by checking expressions you found interesting.
When you want to transcribe English, the key is to choose an AI transcription service that excels in foreign languages.
One such service, 'Mojiokoshi-san', supports 100 languages, and of course, it can transcribe English with very high accuracy.
Transcription Websites Have Many Use Cases
As you can see, even just off the top of my head, there are truly various potential use cases.
In the future, "the ability to skillfully use transcription tools" might become one of the differentiators for successful business professionals.
Summary of Transcription Website Usage
This time, we discussed transcription websites that can be used from your browser.
Finally, here's a summary of the recommended sites introduced:
There are various methods for transcription, but if you're choosing a transcription service usable from a browser now, AI-powered transcription websites are highly recommended.
They offer superior quality in all aspects—speed, affordability, and accuracy—compared to previous transcription services. If you haven't tried them, why not give AI transcription a go?
