Brew better AI answers.
Let the best AI win.
Pit the top AI models against your prompt. We'll tell you which one actually nailed it — and which one was faking it.
The verdict
A real winner. With real reasoning.
Most AI comparison tools dump three columns of output on you and walk away. Lightbrew reads every answer, scores each across four dimensions, and commits to a verdict — with the reasoning to back it up.
Verdict
“Explain embeddings and when to use them.”
Claude
Defined terms before using them; gave three concrete use cases.
ChatGPT
Correct but skimmed over the "when to use" half.
Gemini
Rambled; buried the practical advice in three paragraphs.
Why Claude won
Led with a plain-English definition, then gave three concrete use cases. The others either defined the term vaguely or skipped the practical half.
Blind judging
The judge doesn’t know which model wrote what.
Category scores
Relevance, clarity, creativity, accuracy — each 1–10.
Fact-check
Flags where models disagreed on verifiable claims.
Saved history
Every run kept, searchable, shareable.
Modes
One toggle. Three pours.
Different prompts deserve different depth. Pick a mode and Lightbrew tunes the whole pipeline — which variants run, how long they talk, how thoroughly the judge evaluates.
Power users can still customize variants per model. Most of the time, the preset is the right answer.
Quick Check
~15–25sFASTFastest variants of each model, short responses, minimal judging.
For quick gut-checks — which model best handles this kind of prompt?
Balanced
~45–75sDEFAULTMid-tier variants, standard-length answers, full judging.
Scores + fact-check + prompt tips. The everyday comparison.
Deep Roast
~2–3 minPROFlagship variants, long responses, deeper analysis.
For prompts that matter — the full weight of each model, all the analysis.
Brewtal Mode
Serve the losers dark.
Flip Brewtal on and the judge adds a dedicated “Brewtal Take” card — three to five dry, cutting one-liners about the losing responses. Shareable, screenshot-ready, one click to copy.
The verdict stays professional. The roast lives in its own card. You get both.
Specific, not snark
Roasts the concrete thing that went wrong, not the model.
Copy + share
One click, bullets formatted, ready for Slack or Twitter.
The Brewtal Take
Spicy · share at your own risk
ChatGPT answered like someone who wikipedia'd the question thirty seconds before responding.
Gemini's "thoughtful" take is mostly three paragraphs of hedging and a vibes-based conclusion.
Both skipped the part where the user asked for an example, which was arguably the whole point.
Claude won by doing the bare minimum plus one concrete example. That was the bar.
Sample Brewtal Take. The verdict and scoring live separately — Brewtal is dessert.
