Validate before monitoring in real time
Don't waste executions on weak prompts. Lumen lets you test your questions live against ChatGPT, Gemini, and other LLMs, see results instantly, and mark only the winners as "verified" for automatic monitoring.
Get startedLive streaming execution
See LLM responses in real time with no waiting. Discover what works before spending execution credits.
Bulk test multiple prompts
Load 5, 10, or 20 prompts at once and validate all in a single run. Much faster than one-by-one testing.
Manually verify mentions
Lumen highlights where your brand appeared in each response, but you review and confirm before activating automatic monitoring.
Mark as verified
Only prompts that pass validation activate in your monitoring strategy. Zero wasted prompts.

Write a list of questions you want to test, separated by line or comma.

Lumen runs all against ChatGPT, Gemini, and your configured LLMs. You see full responses instantly.
Review results
Read each response, verify if your brand appears, and check if the position is useful for long-term monitoring.
Mark as verified
Only prompts you approved activate in your dashboard. The rest are discarded or edited and re-tested.
