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 every sample folder you have.

02

Detect BPM and key

Find out the tempo and musical key of any sample. Match sounds that actually work together.

03

Organise thousands of files

Sort, rename, copy, and move samples into structured folders. Let your assistant do the filing.

04

Works where you work

MCP-compatible — tested with Claude Desktop and Claude Code. Mac and Windows. Any DAW — or no DAW at all.

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.
