For songs Songsterr's curated catalog doesn't have
Upload any audio file. Get guitar tabs, a chord chart with 170+ diagrams, and word level synced lyrics in about 3 minutes. No catalog ceiling, no waiting for an editor to add the song.
3 full songs free. No credit card. $6.99/month after that ($4.17/mo annual).

Songs the catalog doesn't have
A curated catalog is a fixed library. The world produces hundreds of thousands of new tracks every week. Here's the music a catalog model can't keep up with, and audio2guitar can.
Songs from Suno and Udio that didn't exist last week. No catalog has them. Upload the audio, get the tab.
Bethel, Hillsong, Elevation drops on Friday and need to be ready by Sunday. Catalog tab editors can't keep that pace.
Songs without a community of contributors. Indie releases, debut singles, side projects, b-sides.
K-pop, Latin, Filipino OPM, Bollywood, Nordic folk. Catalogs index Anglophone hits and skip the rest of the world.
Your demo, your band's draft, the riff you recorded on your phone last night. Catalogs will never have it.
Acoustic re-recordings, MTV Unplugged versions, live arrangements that differ from the studio cut. Catalogs only carry one canonical version per song.
The structural difference
Catalog tools have a supply problem: someone has to make the tab before you can play it. Audio2guitar has no supply problem. If you have the file, you have the tab in 3 minutes.

How it works
Mp3, wav, m4a, flac. Spotify rip, YouTube audio, your own recording. Up to 100 MB on Pro.
Stem separation isolates the guitar. Beam search detects notes, articulations, and chord progression. Sections labeled.
Tabs, chord diagrams, synced lyrics ready in 3 minutes. Loop sections, slow down, export to MIDI on Pro.
Why people switch
Roughly 500 curated tabs is a fraction of what's released every month. Indie, worship, regional, AI generated: none of it is in the catalog when you want it.
Songsterr renders tab notation. Audio2guitar renders tabs plus a full chord chart with 170+ diagrams plus word level synced lyrics. One upload, every output.
$6.99/month versus $9.90/month for Songsterr Plus. Pay less, transcribe any song you want, no waiting on someone else's catalog roadmap.
Songsterr's curated, hand-prepared tab catalog is around 500 songs. Their broader library includes more user contributions and AI generated tabs, but the high quality multi-track tabs are a small set. Audio2guitar doesn't have a catalog, every song is generated from your upload.
Songsterr is great if your song is in their catalog. The moment you want a song that isn't (a new release, an indie track, a regional or worship song, your own Suno generation), you're stuck. Audio2guitar reads audio, so if you have the file, the system can chart it.
Songsterr's AI upload tier accepts audio but bass and lead transcription quality is widely reported as inconsistent. Audio2guitar uses beam search transcription benchmarked at 97.8% string assignment on GuitarSet. Try 3 free songs and compare on the same audio.
Both. Every upload returns guitar tabs, a chord chart with 170+ chord diagrams, word level synced lyrics, and section markers. Songsterr's catalog tier is tab notation only, no synced lyrics or chord diagrams.
Yes. Loop sections, half speed playback, click track, and section by section practice are built in.
Yes. The transcription detects technique articulations and renders them in the tab. Songsterr's curated tabs include articulations, but their AI upload tier does not consistently.
Pro tier includes MIDI export, which opens in any DAW or notation software (Logic, Ableton, MuseScore, Guitar Pro). PDF export is also included on Pro.
Yes. No long term contract. Cancel from your account settings, no email or call required.
