Everything you need to know about SongTools.ai: credits, tools, privacy, and more.
SongTools.ai is designed for a wide range of creators: solo musicians, producers, songwriters, DJs, and even social media managers for artists. Whether you're just starting out and need feedback on your first demo, or you're a professional looking to speed up your workflow, our 30+ AI-powered tools can help at every stage of the music-making process.
SongTools.ai uses a simple credit-based system. Each tool has a defined credit cost, displayed before you use it. You receive 6 free credits when you sign up, enough to try Song Feedback and another tool. When you need more, you can purchase additional credits through our store. No subscription is required and purchased credits never expire, so you only pay for what you use. An optional paid plan is available if you want your uploaded audio kept instead of deleted after 7 days.
Your 6 welcome credits are good for 7 days from sign-up. Make any purchase in that window and they become permanent, along with everything you buy. Purchased credits never expire.
We offer fair, musician-friendly pricing with no subscription required. Most tools cost 1 to 4 credits: lighter text tools cost 1 credit, most analysis tools cost 2 to 3 credits, and premium audio tools like Vocal Remover and Karaoke Maker cost 4 credits. Stem Isolator costs more when you keep more than two stems, and DJ mix tools start higher and scale with the length of your mix beyond an hour. You can see the exact credit cost of each tool before using it. We designed our pricing to be accessible for independent artists and hobbyists while sustaining the platform.
There are a few ways to earn bonus credits beyond your initial sign-up allocation. You can refer friends using your unique referral link, and when they sign up you both receive bonus credits. We also run occasional promotions with promo codes shared via our newsletter and social channels. Keep an eye on the Store page for any active credit bundles or offers.
Instant rhymes in the Rhyme Finder are free and need no credits or sign in. The lightest paid tools cost 1 credit, for example translating pasted lyrics or the Rhyme Finder's AI rap rhymes. Most audio analysis tools cost 2 to 3 credits: Key & BPM Finder and Spectrogram cost 2, while Song Feedback and Transcribe Lyrics cost 3. You can see the exact cost displayed on every tool before you start.
You can upload most common audio formats, including MP3, WAV, FLAC, M4A, and OGG. We recommend WAV or FLAC for the highest-quality analysis results, though compressed formats like MP3 work well for most tools.
The maximum file size for most tools is 80MB. For the DJ Mix Tracklister tool, the limit is increased to 250MB to accommodate longer mixes and sets. If your file is too large, we recommend compressing it to a high-quality MP3 (320kbps) before uploading.
Yes. SongTools.ai is fully responsive and works on smartphones and tablets. You can upload audio files, run text-based tools, and view your results on any modern mobile browser without installing an app. For the best experience with waveform and spectrogram tools, a tablet or desktop screen gives you more room to explore the visuals.
Each tool runs on our proprietary music intelligence layer, a system built on frontier AI models and refined through domain-specific training data, structured evaluation pipelines, and feedback gathered from real-world music analyses. When you upload audio or provide text, the system analyses patterns, structure, frequencies, and content through a music-specific lens developed over millions of interactions. The result is analysis that understands music the way a trained professional does, not a general-purpose chatbot. It acts as a creative assistant and technical co-pilot, not a replacement for your artistic judgment.
Most tools return results within 30 seconds to 2 minutes, depending on file size and the complexity of the analysis. Larger files and more complex tools (like Release Ready Check or DJ Mix Tracklisting) may take slightly longer. You'll see a progress indicator while your file is being processed.
AI MIDI generation has moved to MIDI Lab (midilab.ai), a real-time AI MIDI studio from MIDI Lab AI, Inc., the same company behind SongTools.ai, that streams generated MIDI directly to hardware synths live rather than producing a single downloadable file. If you've purchased credits on SongTools.ai before, use promo code SONGTOOLS20 at MIDI Lab for 20 bonus credits on top of their normal signup bonus.
The Key & BPM Finder is highly accurate for most commercial and well-produced tracks, typically within ±1 semitone for key detection and ±1 BPM for tempo. Accuracy can be lower for tracks with fluctuating tempos, unusual tuning (e.g., A=432Hz), or very sparse arrangements. For DJ and production use cases, we recommend confirming BPM against your DAW's tap-tempo feature if precision is critical.
If a tool encounters an error during processing, your credits are automatically refunded. You'll see an error message with a brief explanation. Most failures are temporary, caused by file format issues, very unusual audio content, or occasional server load spikes. If an error persists, try converting your file to WAV or MP3 and re-uploading, or contact us via the support form in the footer.
Absolutely. That's one of SongTools.ai's main advantages. You can upload a track once and run it through Song Feedback, then switch to the Spectrogram Generator, then the Loudness Analyser, all in the same session. Each tool run uses its own credit cost. Every result you generate is saved to your Library for free, so you can revisit and compare analyses over time.
The Lyric Copyright Checker scans your lyrics for potential similarities to existing published works. It checks phrasing, word clusters, and structural patterns that could raise copyright questions, and flags lines that may warrant closer review. It is an educational screening tool, not a legal determination. Always consult a music attorney if you intend to publish lyrics that closely mirror existing songs.
No, and we never will. Your uploaded audio and any content you submit is used only to generate the analysis or output you requested. It is never used to train, fine-tune, or otherwise improve any AI model, whether ours or a third party's. Uploaded audio is automatically deleted within 7 days; it isn't retained, sold, or repurposed for any other use. On a paid plan it is kept while the plan is active, and deleted when the plan ends.
Your privacy and the security of your creative work are our top priorities. Your audio files are securely uploaded for analysis and retained for up to 7 days afterward, long enough to replay the original file from your Library, then automatically and permanently deleted. Your written analysis results are stored on our servers tied to your account (not just your browser) so they're available across your devices. Your Library is free for every registered user, no purchase needed; see the next question. On a paid plan your audio is kept while the plan is active, and deleted when the plan ends.
No. Your Library is free and permanent for every registered user. Every song and every result you generate is saved from the moment you sign up, and it stays available whether or not you ever pay. What a paid plan changes is how long your uploaded audio is kept: on a free account the audio file is deleted 7 days after upload, so a later audio check needs the file again, while on a paid plan it is kept for as long as the plan is active. Your written results are never deleted either way.
Outputs are provided as a reference and creative aid for your own personal use, at your discretion. SongTools.ai isn't a platform for generating content that's automatically cleared for release. Because outputs are AI-generated, we can't guarantee they're original or free of similarity to existing copyrighted material. If you'd like to use an output (lyrics, sheet music, processed audio like stems or masters, or written copy like bios, press releases, and captions) in something you plan to publish or monetize, you're responsible for reviewing it yourself and securing any rights you need, the same as you would with any other creative material.
Yes, SongTools.ai uses Google OAuth for secure authentication. This means you sign in with your existing Google account, no need to create a new username and password. We only access basic profile information (name, email, and profile photo) and do not have access to your Google Drive, Gmail, or other Google services.
Yes, and it is built for it. SongTools.ai turns any song into words and pictures: its mood and emotion, a written description of what is happening, the lyrics, and a spectrogram that shows the shape of the sound. Producers also get written loudness, mix and vocal clarity reports, no listening needed. Deaf and Hard of Hearing listeners and music makers can apply for free access on our Accessibility page.
SongTools.ai is a comprehensive, all-in-one platform offering 30+ specialized tools in one place. Instead of juggling multiple apps and subscriptions, you get everything from song feedback and mix analysis to lyric writing, lyric translation, rhymes, stem separation, DJ tools, and marketing content. Our pay-as-you-go credit system means you never pay for tools you don't use, and there are no monthly fees.
No. The AI Contract Review tool provides general information and highlights potential areas of concern in music contracts. It is designed to help you ask better questions and have more informed conversations with qualified legal professionals. It is not a substitute for professional legal advice. Always consult a licensed attorney before signing any legal agreement.
You can reach us through the Contact form available in the footer of our website. We typically respond within 24-48 hours. We welcome feedback, feature requests, and bug reports. They help us improve the platform for everyone.
