Stop babysitting AI.
Start creating.
You shouldn't need to be a prompt engineer. Say what you want in your own words. Kosmo asks what an expert would ask, then writes the prompt an expert would write, for the exact AI tool you use.
Expert prompts for the tools you already use.
Kosmo's Knowledge Vault is kept up to date with official documentation, to reduce outdated or incorrect answers.
Example
See it work.
Recorded Kosmo runs for everyday work requests. Kosmo asks what an expert would ask, then writes the prompt for the tool in use.

Why raw prompts fail.
It's rarely the AI model. It's what got left out of the prompt.
Hidden assumptions.
You know what you mean. The AI doesn't. At least not until you spell out every constraint yourself, one frustrating reply at a time.
Tool mismatch.
A prompt written for one AI tool often falls flat in another. Formatting, context limits, and conventions differ more than people expect.
No stopping conditions.
Without clear boundaries, an AI keeps going past where it should have asked a question or stopped to check in.
We verify facts.
Kosmo checks today's official documentation before writing. No more outdated answers or hallucinated libraries.
Expert guardrails added.
We automatically inject the security rules, best practices, and architecture a Senior Engineer would use.
Built-in thinking loops.
Kosmo builds a check-your-work step into the prompt, so the AI double-checks its own work before it answers.
What Kosmo doesn't do.
Being useful means being honest about the boundaries.
We don't pretend every AI tool works the same way. Output is adapted to the tool you're using.
We don't hide our assumptions. Anything Kosmo infers on your behalf is stated plainly, not buried.
We don't compile a broken approach just to be agreeable. If your plan won't work, we say so and fix it first.
We don't train AI models on your work. What you write, and what Kosmo writes for you, stays yours.
Use Cases
For the work you actually do.
A plain request goes in. Here is what Kosmo adds before your AI tool ever sees it.
Sales
Cold emails that get replies
You said
“My cold emails get no replies. I need better ones.”
Kosmo's prompt
Opens each email with one real figure from the buyer's own published reports, and never invents a number: if no credible source turns up, it leaves a placeholder. Short, plain sentences, the product only after their problem, and one low-pressure ask at the end.

Hiring
An interview process that predicts the job
You said
“I need to fix our interview process for senior engineers. Too many bad hires got through.”
Kosmo's prompt
Gives each of the four rounds its own focus, uses work samples from the real codebase instead of puzzles, and has every interviewer submit a score with written evidence before the debrief, so the loudest opinion stops deciding. It also finds current research on structured interviews to show the team.

Founders
Competitor research you can defend
You said
“I need to understand what my four biggest competitors are actually shipping before I talk to investors.”
Kosmo's prompt
Searches each company's own pricing pages, changelogs and announcements, keeps only releases dated in the last six months, cites every fact with a link and date, and labels its own inferences separately. The result is a matrix ready for a deck, not a summary of old marketing pages.

Engineering
200 screens, without a broken month
You said
“Design shipped a new component library and I have to move 200 screens onto it without the app looking broken for a month.”
Kosmo's prompt
Moves one screen at a time and only continues when the app still compiles and renders, stops to ask about old props with no new equivalent instead of guessing, and keeps a progress file. The usage note says to save the rules as a Cursor project rule, so every session follows them.

Careers
Preparation for this panel, not a generic list
You said
“I have a final round interview on Thursday and I am underprepared.”
Kosmo's prompt
Asks for the CV once, maps the preparation to each of the three interviewers on the panel, and gives an honest way to address the experience the job asks for that the candidate lacks, instead of inventing it. Current interview guidance is searched and cited.
Written for Claude
Students
A first portfolio for an internship
You said
“I need a portfolio website to get an internship. I have never built one before.”
Kosmo's prompt
Asks for the CV and the target internship first, plans every page before any code, and writes projects around impact rather than task lists. Typefaces, sizes and colours are set as concrete design decisions, so the site does not look generic.

Which AI tools does Kosmo work with?
Name the tool you use, like Claude Code, ChatGPT, Cursor or Midjourney, and Kosmo writes for it. If you don't name one, Kosmo asks, or picks a sensible one and tells you.
