How to Use

Transcribe offline in four steps

ZoopZip is designed to be obvious: drop a file, pick a model, and get your transcript. Here's the full walkthrough of FREE offline speech to text, plus what every option does.

Getting started

Download a model

Open Configuration → Manage Models and download one. Start with small — it's a great balance of speed and accuracy. This is the only step that needs the internet.

Drop in your audio or video

Drag files onto the window, or click Choose Files. ZoopZip accepts MP3, M4A, WAV, MP4, MOV, MKV and more — and everything stays on your computer. You can also paste a YouTube link instead of a file.

Pick your options

Choose the model, the spoken language (or leave it on auto-detect), and which formats to save. See options explained below.

Click Transcribe

ZoopZip works entirely offline and writes the transcript next to your file — or into a folder you choose. That's FREE offline speech to text, start to finish.

Every option, explained

Model accuracy vs speed

Sets which Whisper model does the transcribing. Bigger models are more accurate but slower and use more memory. A ⬇ mark means a model still needs downloading; unmarked models are ready to use. Start with small — but for non-English audio, consider large-v3 for much better accuracy.

Language of the audio

The language spoken in your file. Leave it on Detect language unless the guess comes out wrong — naming the language explicitly can improve accuracy for tricky recordings.

YouTube link 🔗 YouTube toggle

Click the YouTube toggle at the top of the window to paste a video link instead of dragging a file. ZoopZip downloads the video (up to 1080p, one at a time) and adds it to the queue automatically. Full details on the YouTube transcription page.

AI Cleanup toolbar toggle

Tidies the transcript before it's saved: filler words (“um”, “uh”, “you know”) removed, immediately repeated words collapsed, and spacing, punctuation and capitalisation smoothed out. Timings are untouched, so subtitles stay in sync. Runs on your computer — nothing is sent anywhere.

Speaker labels toolbar toggle

Tags each segment with Speaker 1, Speaker 2 and so on, so interviews and conversations read as a dialogue. Labels appear in every format you save. ZoopZip works this out from the pauses between turns rather than from the sound of each voice, so treat it as a readability aid: speakers who talk over each other, or who don't pause between turns, may be labelled wrongly.

Live Transcribe Configuration menu

Under Configuration → Live Transcribe…. Records your microphone and transcribes it in a rolling few-second window, so text appears while you're still talking. You can edit the transcript as it's being written, and save it anywhere with Save As…. Choose the language before you start — over a few seconds of audio, naming the language is noticeably more reliable than letting it detect.

Save as — TXT

Plain text, just the words with no timings. Best for notes, documents and copy-paste.

Save as — SRT

SubRip subtitles: the words plus when each line is spoken. Use these for video subtitles on YouTube, VLC, Premiere and CapCut.

Save as — VTT Pro

WebVTT subtitles — the same idea as SRT, in the format web video players expect. Choose this for a website.

Save as — JSON Pro

Every segment with its exact start and end time, for feeding into other software. For developers.

Save Location Configuration menu

By default transcripts are written beside the original file. Choose Configuration → Save Location → Choose Folder to send them all to one folder instead — and create a new folder right there if you need one.

App Language Configuration menu

The language of the ZoopZip interface itself (separate from the audio language). Found under Configuration → App Language, with 12 languages available.

Choosing a model

Not sure which to pick? Use this quick guide — and see the full system requirements for memory and speed per model.

  • tiny / base — fastest, for quick notes or a low-spec computer
  • small — the recommended all-rounder for most people, and the model ZoopZip installs by default
  • medium — when you need higher accuracy and have the RAM
  • large-v3 (Pro) — the best accuracy overall, and strongly recommended for non-English audio and accents
