What formats are supported?

Ugle supports MP4, MOV, MKV, MP3, WAV, M4A, AAC, FLAC, and OGG formats out of the box.

Does Ugle upload my files to the cloud?

No. Everything happens directly on your machine. We do not upload your media files, transcripts, or search indexes to any servers.

Can I move my source files after indexing?

If you move your source files, you will need to re-link the folder so Ugle knows where the original files are located to play them back.

How long does indexing take?

It depends on your hardware. On an Apple M-series chip, it typically takes about 4 minutes to process one hour of audio or video.

Does it work without an internet connection?

Yes. Once downloaded and installed, the transcription and indexing processes do not require an active internet connection.

How Ugle works.

One Click to Connect your archive. Build a local index. Search anything inside. Nothing leaves your device.

01. Connect Your Archive

Connect to any local folder or online drives like -GDrive, OneDrive, any other online cloud storage platform. Ugle accepts MP4, MOV, MKV, MP3, WAV, M4A, AAC, FLAC, OGG. No file size limit.

Ugle reads from the original location and stores only the index. Source files stay exactly where they are. Multiple files queue and process in order.

02. Ugle indexes it

The transcription engine runs entirely on-device. No network connection required after installation.

Hardware	Indexing speed
Apple M-series	~4 min per hour of audio
Intel processor	~10 min per hour of audio

Indexing runs in the background. Ugle notifies you on completion. The index stores the full transcript, speaker timestamps, and a semantic embedding per passage. Index size: 2–5% of source file size.

03. Search anything

Open search with Cmd+K or Ctrl+K. Type a word, phrase, or concept. Ugle returns every matching moment across all indexed files, ranked by relevance, with timestamp and a three-line excerpt.

Results appear in under 30ms. Semantic search is on by default — searching ‘housing policy’ finds passages about rent control or zoning, even if those exact words were never spoken.

Click any result to jump to that moment in the transcript view. Play the clip, copy the transcript, or export the segment.

Clip extraction

Highlight any transcript passage.
Preview the corresponding video or audio segment.
Set in/out points via timeline or transcript selection.
Export as MP4, MP3, or WAV to a folder of your choice.

Audio-only exports do not re-encode — Ugle extracts directly, making export near-instant.

The Library

Search across your entire Library from a single query.
Filter by date range, file type, or language.
Add tags and notes for editorial organisation.
Portable — move the folder to an external drive. Ugle reconnects automatically.
