Small tasks. Simply done.

A little less hassle.
A lot more done.

ToolYogi brings useful online tools into one simple place. Our goal is to make everyday tasks easier, with a clear interface and honest explanations of what each tool can do.

Starting small. Growing useful.

Today you can use our BPM & Key Finder to estimate tempo and musical key, our LUFS Meter to check audio loudness, our Stem Separator and Vocal Remover for local AI separation, our Audio to MIDI Converter for browser-side note transcription, or our Image Compressor to reduce image file size. These tools run in your browser without requiring an account.

We plan to keep growing across file, image, text, developer and productivity tasks. Tools are added when they are useful and ready to use.

Useful tools, clear limits

Automatic analysis and browser-based processing have limits. We explain how our tools work and where results may need a human check. ToolYogi’s audio analyzers are convenient starting points, not certified measurement instruments.

Open-source acknowledgements

Our audio analysis approach is adapted from Tonalux Analyzer by Exenye, an MIT-licensed project. We use its fallback DSP approach; the optional Essentia.js integration is not included. The upstream license notice is available with the source project.

Audio-to-MIDI transcription uses Spotify Basic Pitch, an Apache-2.0 licensed automatic music transcription project, through a browser-first integration.

Our interface uses Lucide icons. We evaluate licenses and retain required notices when integrating third-party work.
