Frequently Asked Questions
Answers to common questions about our services, technology and pricing.
General
What is KolWrite?
KolWrite takes a recording and gets you what you needed from it: text you can read and edit, speakers separated, subtitles burned into the video, a summary, and the moment you were looking for. It runs on Apple Watch, iPhone, iPad, Android, Mac and in any browser.
How accurate is the transcription?
Accuracy depends on the recording and on the model you choose. One microphone per speaker, less echo in the room and less talking over each other all improve the result.
Can KolWrite make an SRT subtitle file from my video?
Yes. Upload a video or audio file, transcribe it, correct the text, and export SRT or VTT. You can translate the transcript first to get subtitles in another language, or burn the captions into the video. Hebrew and Arabic are laid out right to left.
Is there an API for developers and AI agents?
Yes. The KolWrite API takes the address of an audio or video file and returns the transcript with word timings, speaker labels and, if you ask for it, an SRT file. The API console at console.kolwrite.com has the keys, the documentation and plain-text instructions an AI agent can read before it writes code.
Models and how to choose one
Which model runs where, what each one gives up, and why we publish no accuracy number.
Which model transcribes my file?
Whichever you pick. Oracle Mini is the fastest, but it doesn't separate speakers or translate. Oracle and Oracle Pro suit most work. Oracle Max is for difficult audio. Base runs on your own computer or phone and costs no credits.
How accurate is it?
We don't publish a number. We've measured our on-device model on a public Hebrew test set, but it's our weakest option and the figure would read as a promise about the cloud. We're holding it until the cloud has been measured the same way.
Does it support translation?
Yes. You can get the transcript in English or another language at the same time. Only Oracle Mini doesn't translate.
Does it handle professional terminology?
Yes. The business and enterprise plans include terminology and detection tuned for medical, security and enterprise work. Write to us for details.
Security & Privacy
Is my data safe?
Yes. Connections are encrypted, and so are the files you store. Our main servers are in Germany. Our Security Page explains where your data is processed and who our providers are.
Do you use my data for training?
No. We do not use your content to train AI models. You can delete your recordings, files and account at any time.
Where do the models run?
Our best and most accurate models run in the cloud. For full privacy, you can also transcribe locally, on your own device.
Billing & Plans
Can I cancel anytime?
Yes, any time. You keep access until the end of your current billing period.
Do you offer custom enterprise plans?
Yes. For large teams, high volume or special security needs, contact our sales team.
