Suno

Suno generates complete songs from text prompts. You describe a genre, mood, or topic, and Suno produces a track with vocals, instrumentation, and sometimes original lyrics. Version 4 (released late 2025) significantly improved vocal clarity and genre range. The tool runs entirely in-browser with no local installation required.

The generation process typically takes 30 to 90 seconds. Each generation produces two variations. Users can extend tracks, remix sections, or provide custom lyrics. The interface is straightforward: type a prompt, pick a style, and generate.

Suno operates on a credit-based freemium model.

The free tier provides 10 credits per day, enough for roughly 5 song generations. Free-tier outputs carry a non-commercial license.

The Pro plan costs $10/month and includes 500 credits (approximately 250 songs). Pro subscribers get commercial rights, priority generation, and the ability to generate up to 4-minute tracks.

The Premier plan at $30/month provides 2,000 credits, all Pro features, and early access to new models.

Commercial use is permitted on Pro and Premier plans. Suno's terms state that paid subscribers "own" their generated outputs and can use them commercially, including on streaming platforms.

However, Suno has not disclosed its training data sources. Multiple lawsuits (notably from the RIAA, filed June 2024) allege that Suno trained on copyrighted recordings without authorization. Suno has neither confirmed nor denied specific training sources.

This creates a medium rights risk: you likely will not face issues using Suno outputs commercially, but the legal landscape is unsettled. If a court rules that AI-generated music trained on copyrighted works constitutes infringement, downstream liability for users is theoretically possible.

Suno does not apply audio watermarks to outputs. There is no embedded metadata identifying tracks as AI-generated.
