Write what you mean.Get a prompt that’s already proven to work.
Describe it like you’d tell a coworker. Meerkat drafts it across ChatGPT, Claude & Gemini, then runs it on real models to prove it holds — before you paste it.
in their words
“I can usually give a fairly rough explanation of what I'm trying to do and it turns that into something much more structured and useful. I gave Meerkat and Codex the same task and actually used both prompts, and the Meerkat one gave me the better result.”
vague. lazy. vibes.are out. Specifics ship.
Models don't need motivation, they need a job description. You tell Meerkat what you're trying to make; it asks the things a senior editor would ask before touching the keyboard, then writes the prompt for you in the format the model actually prefers.
- ROLE
- You are a senior support lead, calm under fire.
- TASK
- Draft one reply to the message pasted below.
- CONTEXT
- A paying customer, threatening to cancel.
Goal: keep them — without overpromising. - RULES
- Name their exact problem first.
Promise only what policy allows.
Escalate anything legal or safety to a human.
Watch what you mean become a real prompt.
> waiting for your first answer
Ask one model, get one read on it.
A single model only ever shows you its own take — you tweak against the one model that wrote it and hope it holds. Meerkat reads your brief across the frontier labs, keeps the strongest move from each, then runs the result on real models to see what actually holds. So you ship from proof, not a hunch.
Gemini
Reframes the ask around who actually reads it.

the wrong audience, perfectly executed
Anthropic
Claude
Argues with the brief before it answers — catches the vague success metric.
without it
a confident answer to the wrong question
OpenAI
ChatGPT
Locks the output to a strict, copy-ready format.

a good draft you still have to reshape by hand
Meerkat’s merge
best of eachEvery move, kept. Nothing missed.
The right audience from Gemini, the sharpened brief from Opus, and the strict format from GPT — composed into a single prompt you copy once and ship. One model could only ever have given you a third of that.
most “prompt enhancers”
Graded on paper.
They read your prompt and hand it back tidier — a role, some bullets, a format, a tidy confidence score like 91/100.
It never finds out whether the prompt actually works. Neither do you.
the difference that matters
Proven on models.
Meerkat runs the prompt on real frontier models, judges what comes back, and repairs what breaks — before you ever paste it.
You ship knowing it holds — not hoping it reads well.
We don’t just build the prompt. We prove it works.
Our own test, not a third-party benchmark: each prompt runs on a fresh input, then a separate model — told nothing about which side it’s judging — scores the result from 0 to 5.
Completeness measures how fully a prompt holds its instructions across inputs — not just the easy one. Same models on both sides; only the prompt changed.
- the ask
- Pull clean, structured fields out of a messy job posting.
- the curveball
- The posting names a staffing agency, but the real employer is only described — never written out.
Meerkat’s merge: Resolved the employer by an explicit rule and returned valid, copy-ready JSON. Judged airtight.
A typical prompt: Left the hardest field empty rather than resolving it — complete-looking, but wrong on the input that mattered.
We get the bones right.You just talk.
Every strong prompt rests on four bones — role, task, context, rules. A template hands you four empty boxes; you still fill them. Meerkat covers whichever ones your task needs and shapes them to fit — tight schema for extraction, room to breathe for a brief — all pulled from a two-minute chat, not a framework you have to learn.

have Meerkat write me a prompt that turns my raw meeting notes into a 3-bullet exec summary for my CFO. she hates fluff.
Got you. Your CFO is the audience, not you — so the prompt has to ban hedging, rank by dollar impact, and cap each bullet at one line.
You are summarizing meeting notes for a CFO who has 90 seconds.
Rules:
- Exactly 3 bullets. Each one ≤ 18 words.
- Lead each bullet with the dollar impact, the deadline, or the decision owner — whichever is loudest.
- No hedging words: "potentially," "might," "could," "exploring."
- If a number isn't in the notes, say "TBD" — never invent one.
Notes:
{paste meeting notes here}Want me to harden it against jargon, or add a fallback bullet for when the notes are thin?
Meerkat doesn’t flatter. It roasts.
A gallery of the prompt mistakes everyone makes — one clean specimen of each, written by us and run through the real Meerkat. Every card names the failure it caught and opens the full roast and the rebuilt prompt.
“'Make it pop' is three words of pure wish — you've handed the model a mood board, not a brief.”
“'Good and memorable' is a wish, not a brief — you've described every name ever made and ruled out exactly none.”
“'World-class expert with 20 years of experience' is a LinkedIn headline, not a brief — and 'help me with my go-to-market strategy' is the entire contents of a…”
“'So people understand it' is the entire spec — which people, understanding what, to do what with it?”
“'Pour your heart into it' is instructions for a barista, not a language model — the model has no heart, no coffee, and no idea what makes yours different.”
“'Detailed but short, thorough but brief, professional but casual' — you've written four constraints that cancel each other out and called it a brief.”
“Two hundred words of biography, zero words of an actual question — 'what to do next' is not a question, it's a shrug.”
“'Gets replies' is the whole brief — you've described the desired outcome and left the model to invent the product, the sender, the recipient, the ask, and the…”
“'95% certain' sounds rigorous until you remember the model has no certainty meter — it'll ask one question or twelve, and neither feels wrong to it.”
“Five 'don'ts' and zero 'dos' — you've handed the model a list of landmines with no map to the destination.”
“You buried a bakery brief under so many pleases and maybes that the only thing the model knows for certain is that you're polite.”
“You buried a perfectly clear question under a paragraph of grief — the model doesn't need your grandmother's Sunday routine to recommend a beginner loaf.”
Free to try. Cheap to keep.
A free template doesn’t fix a weak prompt — it just moves the bill to the reroll spiral, where every “try again” burns tokens and minutes. The cheapest prompt is the one you only run once.
