audio2guitar vs Songscription

audio2guitar is a web app that converts uploaded audio into guitar tablature, chord diagrams and lyrics synchronized to the tabs. Its process isolates guitar, detects notes and chords, maps notes to fret positions and creates the notation. Free users upload MP3 files; Pro also accepts WAV, FLAC, M4A, OGG and AAC. The maker says it detects more than 170 chord types and annotates hammer-ons, pull-offs, slides, bends, vibrato and palm mutes. Pro adds MIDI and PDF export, separated vocals, bass, drums, guitar and piano stems as MP3, per-stem MIDI, and playback from 25% to 100% speed while preserving sync and pitch. A valid Google account is required. The homepage reports 97.8% string-assignment accuracy on GuitarSet and says clean recordings with prominent guitar work best. Most songs process in 3–6 minutes. Plans include Free at free, Pro Monthly at $8.99 a month, Pro Annual at $59.99 a year, and One-time at $9.99, paid once.
