Frequently Asked Questions

Which tools are free?
Audio Cutter, Song Joiner, Pitch Shifter and Noise Remover are completely free and unlimited — no account, no credits. Only the AI-heavy Vocal Remover and Stem Splitter use credits, because they run a large neural network.
How do credits work?
Each AI audio separation (Vocal Remover or Stem Splitter) costs 10 credits per song. Video tools: removing a watermark or background costs 2 credits per minute of video — a clip up to 1 minute is 2 credits, a 10-minute video is 20 credits. The ₹27/month plan gives 1,000 credits; the ₹299/year plan gives 20,000 credits plus 20 free credits every day. The ClipCut video editor is free.
Does my audio get uploaded to your servers?
No. 7By.in processes everything locally in your browser. Your audio never leaves your device — credits simply meter access to the AI tools.
Do unused credits roll over?
Monthly credits reset each month. Annual credits are valid for the full year, and the +20 daily free credits are a bonus on top that refresh every day.
Can I get a refund?
Yes — if you've used fewer than 50 credits, email us within 48 hours for a full refund.
