How it works

Three steps from recording to finished work

1
Upload anything recorded

Audio or video, up to ten hours in one file. The language and the number of speakers are detected for you, or you set them yourself when you already know.

Progress with stage and time left
2
Review in the editor

Play it back with the line highlighted, fix a word, rename a speaker everywhere, move a line to the right person.

Click a line to play from it
3
Turn it into finished work

Export DOCX or PDF, generate minutes, action items, subtitles, chapters or a call report.

Every item timestamped
Accuracy & speakers

“Speaker 2” becomes a name

Speakers are separated automatically, and the line being spoken stays highlighted while you listen. When the engine gets one wrong, you move it to the right person in one click — or merge two speakers it split by mistake.

The highlighted word follows playback, so you can read and listen at once.
Every transcript says what share of its words the engine was unsure about, and underlines them — so proofreading takes minutes, not a second listen.
Rename a speaker once and it changes across the whole transcript.
Your glossary teaches the engine your names and jargon before it listens, whichever language you record in.

Good morning, Ms Weber. Thanks for making time for the review today.

The first phase is meant to close in October, but I am not sure the Munich team will have the data ready in time.

Agreed. I will put together a short summary and send it to everyone today.

Privacy first

Your recordings, treated as somebody's conversation

Encrypted the moment they land in our storage, processed only in the European Union, and gone for good the day you delete them.

Security & privacy →
Encrypted, every file on its own

Each recording gets its own key, so nothing is readable in bulk. Transcripts and documents are locked the same way.

Processed in the EU

Our server is in Warsaw and the GPUs are in Romania. Nothing is processed outside the EU.

The audio stays put

AI documents and translations are made from the text. The recording never leaves storage for them.

Delete means delete

Deleting your account removes every recording, transcript and document, including the audio in storage.
