What it does

Everything you need to find a sound — nothing you don't.

01

Search by describing what you want

"Dark atmospheric pads." "170bpm drum breaks." "Bright analog snares." Type what you need, get what matches — across your library.

02

Detect BPM and key

Find out the tempo and musical key of your samples — read from the filename when it's labelled, estimated when it isn't. Search for a tempo range, like shakers between 170 and 178 BPM.

03

Organise thousands of files

Sort, rename, copy, and move samples into structured folders. Let your assistant do the filing — and undo a rename if you change your mind.

04

Works where you work

MCP-compatible — tested with Claude Desktop and Claude Code. Mac and Windows. Any DAW — or no DAW at all. Digr runs locally: your files aren't uploaded, and nothing is used to train AI.

Who it's for

If you have a sample library, Digr is for you.

Digr is for anyone who works with audio samples — not just music producers. If you have a library, Digr helps you find what you need without endless browsing.
