Which AIs are supported?
Promptglow works with all major models: ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), Mistral, Microsoft Copilot and many others.
How long does the analysis take?
Analysis typically takes between 10 and 60 seconds, depending on prompt complexity. In some cases, it may take up to 2 minutes.
Is the service really free?
Yes, completely free and no sign-up required. The site is funded by advertising (Google AdSense), which allows us to keep this service accessible to everyone.
Is there a usage limit?
To prevent abuse, a limit of 10 analyses per hour per IP address applies. This is more than sufficient for individual use.
