RetraceFind the AI behind anything
Paste text, a website address or an AI app name, or add an image. Retrace tells you which AI made it and recovers the prompt, model and settings when they are still there.
Images
Generator, exact prompt, seed, model and LoRAs from file metadata and Content Credentials.
Text
Which chatbot wrote it, from citation traces, self-identification, style and hidden characters.
Websites
AI chat widgets, AI APIs, AI site builders, llms.txt, AI crawler rules and agent skills.
AI apps
Published system prompts, tool definitions and skills from public GitHub collections.
Prompt library
Search public collections of leaked system prompts, tool definitions and agent skills for an AI product or model.
API test
Identify the model behind an OpenAI-compatible chat API and check whether it reveals its instructions and tools. Use it only on APIs you own or may test.
Settings
Optional. Connect any OpenAI-compatible model to get a best-guess prompt for files with no metadata. Local models such as Ollama and LM Studio work without a key.
