Why this exists, in plain terms: AI answers don't come with a built-in warning label for how much to trust them. A well-written, confident-sounding answer can be completely reliable, or completely wrong, and the writing style doesn't tell you which. What actually determines the risk is four separate things about your task: how common the request is, how well-known the topic is, how much context the task needs to hold onto, and how precisely you specified what you want. This tool locates your task on all four, in one place, and shows you exactly what changes when you compensate for each one.
This is what the tool produces once you've run both prompts externally and pasted the results back in — shown here with a topic already filled in, so you know what to expect before you start.

Photosynthesis is the process by which plants convert light energy into chemical energy stored in glucose. It occurs mainly in the leaves and involves two stages: the light-dependent reactions and the light-independent reactions (Calvin cycle). In the light-dependent reactions, photons strike chlorophyll in the thylakoid membranes, exciting electrons and driving a proton gradient that powers ATP synthase. Photolysis of water releases oxygen while electrons pass to NADP+, forming NADPH. The Calvin cycle then uses that ATP and NADPH to fix CO2 into glucose in the stroma. Overall: 6CO2 + 6H2O + light → C6H12O6 + 6O2.
Part 1 of 3 — The plant's solar panel: sunlight hits chlorophyll inside a leaf's chloroplasts, and an electron jumps to a higher energy state — the first step of capturing that energy. Part 2 of 3 — Splitting water: the plant breaks H2O apart, releasing oxygen (the air we breathe) and using the hydrogen to charge two "batteries," ATP and NADPH. Part 3 of 3 — Building sugar from air: those batteries power the Calvin cycle, stitching CO2 into glucose in the stroma — a bean plant growing taller is literally made from air, water, and sunlight.
Nothing here is faked — the tool only ever builds the two prompts and diffs the two real results you paste back. Judging which is "better" is still your call, or the analysis prompt's, run for real.
