# Rifflog > Rifflog lets you write guitar tabs, attach a recording, and share one link — as the audio plays, the tab advances step by step in sync. It supports guitar, bass, ukulele, mandolin, banjo, and any custom tuning. Tabs are private by default and can be shared with named emails or a single link; viewers don't need an account. Rifflog is a web app (https://rifflog.com). It's free to start. Beyond the editor, it can export a tab as a scrolling overlay for playing videos. ## Main - [Home](https://rifflog.com/): what Rifflog is and who it's for — bandmates, teachers and students, solo writers, and content creators - [Demo](https://rifflog.com/tab/demo): interactive editor demo with a pre-synced guitar riff, no account required - [Sign up](https://rifflog.com/signup): create a free account ## Free tools - [Chord Finder](https://rifflog.com/tools/chord-finder): identify a chord from a fingering, in any tuning - [Key Finder](https://rifflog.com/tools/key-finder): find the key from notes selected on a fretboard - [Key Explorer](https://rifflog.com/tools/key-explorer): scale notes and diatonic chords for any key or mode - [Tuner](https://rifflog.com/tools/tuner): real-time microphone tuner for any instrument ## Legal - [Privacy Policy](https://rifflog.com/privacy) - [Terms of Service](https://rifflog.com/terms) ## Contact - hello@rifflog.com
