Found a bug, got a question about any of the tools, or an idea for the next one? Write it below — messages go straight to the person who builds the suite. Leave an e-mail address if you'd like a reply; it's optional.
Shinobi Tools is an independent suite of free, browser-based AI tools for everyday tasks: background removal, photo restoration, audio stem splitting, passport photos, audio transcription, document scanning and noise removal. Every tool is free, requires no account, and deletes uploaded files automatically after processing. You can also reach us directly at [email protected].
Bug report: mention which tool (BGNinja, StemGrab, etc.), what you uploaded, what you expected, and what went wrong. A screenshot or browser console error helps us find it faster.
Feature or tool suggestion: describe the use case — what you were trying to do and why existing tools didn't cover it. We read every suggestion.
Question: most common questions are answered in each tool's FAQ or guide pages. If you can't find the answer, ask here.
We aim to reply within 1–3 business days when an e-mail address is provided. Messages without an e-mail are read but cannot be answered individually.
