How we handle your data

Three principles we apply to every single tool.

Files deleted instantly

Uploaded documents are processed and deleted from the server the moment you download the result. We store nothing.

No external APIs

Processing runs solely on our own server. We never pass your documents to OpenAI, Google, Amazon or any other external service.

No sign-up

No accounts, no email addresses, no passwords. Just upload a file and get the result. The one exception is transcription — the result appears right on the page or arrives by email, along with an AI summary and meeting minutes.

Audio and video transcription to text online

Turn recordings of meetings, interviews, lectures and calls into text.

Audio and video transcription

Upload up to 3 audio or video files and get an accurate text transcript by email. We support Russian, English and mixed speech. Processing runs on our own server via faster-whisper — no external APIs or clouds.

Frequently asked questions

Answers to the key questions about security, how the tools work and their limits.

Is it safe to upload documents? Are files kept on the server?
No. Uploaded files are processed and deleted from the server as soon as you download the result. We store nothing and never share your data with third parties.
Do I need to register or install any software?
No. Every tool runs right in your browser — no registration, no software to install, no account to create. The one exception is transcription: the result appears right on the page or arrives by email, along with an AI summary and meeting minutes.
Are files sent to OpenAI, Google or other external services?
No. All processing happens on our own server. We do not use OpenAI, Google Cloud, Amazon or any other external API. For PDFs we use Ghostscript and LibreOffice, for OCR — Tesseract 5, for transcription — faster-whisper. Everything runs locally.
Are there any file size limits?
PDF tools accept files up to 200 MB. Audio and video transcription supports files up to 500 MB. There is no limit on the number of operations.
How much do the tools cost?
Every tool is completely free. No hidden fees, no subscriptions and no limits. We built them as a complement to our core consulting business — for the convenience of our clients and everyone who works with documents.
Do the tools work on a phone or tablet?
Yes. Every tool is mobile-friendly and runs in the browser on iOS and Android, with no app to install.
Can I compress a PDF to a specific size, say 1 MB?
The achievable size depends on the original content of the file. The compression tool lets you choose a quality level: screen (72 dpi), e-book (150 dpi) or print (300 dpi). The lower the dpi, the smaller the resulting file.
Are scanned PDFs supported when converting to Word?
For scanned PDFs we recommend running the OCR tool first — it recognizes the text and adds a text layer. After that, conversion to Word will be far more accurate.
