Questions
Does Prompt Cleaner use AI?
No. It applies local text cleanup rules for spacing, chat labels, blank lines, and wrapping code fences.
Can this clean copied chat transcripts?
Yes. It can remove common User, Assistant, System, Developer, Human, AI, ChatGPT, and Claude labels while preserving the text body.
Does this change my prompt automatically?
The cleaned output updates locally as you edit options. Review it before copying into another AI tool.
Does Utilumo upload my input?
No. Utilumo has no backend that could receive your input. Where a tool makes a request as part of its function, it goes directly from your browser to the destination you choose, never through Utilumo.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
