Most AI tools give every idea a 7/10. Litmus doesn't. Bad ideas score low — brutally honest, calibrated scoring with no grade inflation. Toggle between Plain English and Standard output. Confirm your idea before any credits are spent. And instead of one AI guessing, dedicated agents handle competitor research, market dynamics, pivot strategies, and the final verdict separately — then combine into one cohesive report.

Look at how Litmus have cooked my idea for trying to create another ride-hailing app in Singapore: https://runlitmus.com/saved/74da... I'm the kind of person who always has ideas - too many, too often. And every time I tried to validate them, I'd ask Claude and get the same thing: "Great idea! The market is growing! Here are 5 reasons this could work." Felt good for 10 minutes, then I'd realise I just got people-pleased. I also found most reports either too technical to share with non-technical co-founders, or too shallow to actually trust. So I built Litmus. One platform, multiple specialised agents - each focused on one job - combining into a single consistent, honest report every time and a rating. Competitor research, market dynamics, pivot strategies, and a verdict that doesn't care about your feelings. If your idea is bad, Litmus will tell you. That's the whole point.

Most tools are built to make you feel good. Litmus is built to find every reason your idea will fail - and eventually gives you pivots.

The scoring is calibrated on purpose.
