Write full songs, lock down vocal artist personas, control exact instrumentation with Strict Mode, and practice with real-time word-synchronized karaoke.
Most AI song generators force you into continuous recurring monthly contracts, penalizing you whether you made 1 song or 50.
We built AI GrindStone on a pure pay-as-you-go token model. When inspiration hits, generate dual audio takes with full commercial stem separation readiness, custom outro continuation, and instant video visualizer exports.
Everything you need from lyric drafting to multi-track MP3 and MP4 output.
Clone the vocal character and style of any completed track. Select that persona on subsequent songs to build a consistent-sounding band or EP.
Powered by official word-level timestamps. Click any lyric phrase to scrub your audio directly to that exact line in real time.
Stuck on lyrics? Type a one-line idea (e.g. “10th mile uphill marathon push”) and our engine crafts the verse, chorus, and guitar solo structure.
Song ending too soon? Pick your target second mark, add an extended guitar solo or outro choir, and build full 4-5 minute tracks.
Convert any generated track into an animated audio spectrum video visualizer ready for instant upload to YouTube, TikTok, or Instagram.
Locks negative prompts to stop surprise instruments. Suppress acoustic guitars, synths, or wild artifacts with strict weighting.

“Being able to isolate vocal artist personas across different tracks finally made it possible to create a cohesive motivational heavy metal EP without the vocals changing singer on every track.”
“The karaoke sync feature works seamlessly. You click the lyric line in the prompter and the audio jumps straight to that timestamp. Plus, no monthly billing headache.”
“Strict mode is huge. Before, other platforms would throw in random guitars or synths when I specifically asked for an acoustic beat. Here, what you prompt is what you get.”
