For marketers, sales & operators who live in AI

Stop re-explaining your project to every AI.

  • You rewrite the same instructions from scratch every time.
  • What works in ChatGPT you redo by hand in Claude or Gemini.
  • Your prompts are hit-or-miss — sharp one day, vague the next.

Save the goal, context, and rules once — then brief ChatGPT, Claude, or Gemini with one click.

Start free: grade any prompt, fix it in one click, and keep the ones that work.

The problem

Your AI work dies in the chat window.

You build up context with an AI over a session — the goal, the rules, what's been decided. Then the chat ends, and next time (or in the next model) you start from zero, re-explaining everything by hand.

Your prompts and context should be an asset you keep — not something you rebuild every session.

Promptmkr keeps them, and primes any AI with them in one click.

Why not just use Claude Projects or ChatGPT memory?

Because they only work inside their own model. Claude Projects can't prime ChatGPT. ChatGPT memory can't follow you to Gemini. Promptmkr is the neutral layer that holds your project once and primes any of them.

Claude Projects keeps context — inside Claude.

Promptmkr primes Claude, ChatGPT, Gemini, or Cursor.

Model memory locks your work to one vendor.

Your project is portable — switch models without re-briefing.

Chats and memory vanish when you switch tools.

Your prompts, context, and primers stay in one place.

From vague request to stronger AI instruction.

The value is not prettier wording. The value is adding the structure that makes the model useful.

The foundry

Start rough. Leave with a stronger prompt worth saving.

The Foundry adds the structure most rough prompts are missing: context, variables, constraints, decision logic, and output format.

  1. 01

    Start rough

    Drop in a half-formed request. No prompt-engineering skill required.

  2. 02

    Build structure

    Promptmkr turns the idea into a role, task, context, variables, constraints, and output format.

  3. 03

    Refine the logic

    Add decision criteria, simplify bloat, or convert one-off details into reusable inputs.

  4. 04

    Test and save

    Run the prompt, inspect the output, then save the stronger version to My Prompts.

One-click refiners

Improve the prompt before you waste another AI run.

See exactly what Promptmkr added.

No mystery rewrite. Promptmkr shows the structure it added so you can trust why the prompt got stronger.

  • Persona added: direct-response sales writer
  • Variables added: {{business}}, {{customer_type}}, {{offer}}, {{main_objection}}
  • Constraint added: avoid generic pet-care claims
  • Output format added: 3 subject lines + one short email
  • Reuse layer added: can run again for a new offer, customer, or campaign
  • Decision logic added: rank options, reject weak ideas, and explain the recommendation

Built to remove generic AI sludge.

Promptmkr adds constraints that block filler phrases, vague strategy language, and polished-but-empty AI copy.

Model routing

Right model, every task.

PromptMkr detects what a prompt is for and pre-selects the model that did it best in our own cross-model evals. It's advisory — you always choose what actually runs.

ClaudeStrategy, reasoning & creative writing
GeminiData extraction & structuring
GrokCode & everyday tasks
GPT-5Quality-max fallback — strongest output when speed isn't the priority

Tuned on real Foundry prompts across all four models — switch the model anytime before you run.

How the loop works

Prime → work in any AI → capture → repeat

Your project lives in Promptmkr. Prime any model with it, do the work, paste the result back — and every next primer is smarter than the last.

Prime

Prime any AI in one click.

Drop your project's goal, rules, and latest progress into Claude, ChatGPT, or Gemini — formatted for that model. No re-explaining, no cold start.

Capture

Paste the result back.

When the AI produces something, paste it in — Promptmkr summarizes what happened and what's next, so your project stays current with zero typing.

From rough idea to reusable asset.

1. Rough request
Help me market my new app to founders
2. Promptmkr-built prompt
You are a senior go-to-market strategist known for shipping fast, high-leverage growth plans for early-stage SaaS.

Design a concrete 30-day marketing plan for {{product}} targeting {{audience}}.

Do not give generic advice.

You must:
- Prioritize channels that can produce results within 30 days
- Reject low-leverage channels explicitly
- Name specific communities, keywords, creators, and tactics
- Tie every recommendation to the audience's actual behavior
- Identify the strongest positioning angle before listing tactics

Output format:
1. Positioning diagnosis
2. Best target customer
3. Top 3 channels ranked by speed-to-impact
4. 30-day execution plan
5. Messaging angles
6. What not to do
7. Metrics to track

Constraints:
- Be specific and opinionated
- Prefer concrete actions over strategy language
3. Test output

Positioning diagnosis. Your wedge is “stop rebuilding the same prompt every campaign,” not “another AI tool.” Lead with the asset metaphor.

Top 3 channels. 1) Founder-led posts on X. 2) Marketing subreddits. 3) Cold email to operators already running 3+ AI tools…

30-day plan. Week 1 — ship the public foundry. Week 2 — publish three teardowns. Week 3 — outbound to 100 operators…

The value is not picking between models. The value is giving the model better instructions and saving the prompt that produced useful work.

A populated library — yours, after a few hours.

FAQ

Common questions.

What exactly is promptmkr?

Promptmkr is a prompt improvement system and prompt library. It turns rough requests into structured prompts with role, context, variables, constraints, decision logic, and output format. Then you can test, save, reuse, and export the prompts that work.

Why not just use ChatGPT?

If you only need one answer, ask ChatGPT directly. Promptmkr is for prompts you expect to improve and use again. It shows what structure is missing, adds logic and variables, lets you refine the prompt, and saves the stronger version outside the chat.

Do I need my own AI subscriptions or API key?

No. Promptmkr runs the model on our keys. Paid plans include daily Foundry action limits: Pro includes 30/day and Power includes 100/day. The homepage demo is separate and rate-limited. Saving and reusing prompts is unlimited. You can also copy any saved prompt into your own AI tools whenever you prefer.

Who is this actually built for?

Marketers and revenue-focused operators first — people who run launches, write copy, do customer research, and ship outbound. Business owners, salespeople, entrepreneurs, and creators get the same foundry, with use-case patterns tuned to their work.

Where are my prompts stored?

Today, saved prompts live on your device, which keeps the product fast and private while we ship. Paid users can export their library as Markdown or JSON anytime. Do not treat local storage as team backup yet — cloud sync is planned.

Can I cancel anytime?

Yes — one click. 14-day no-questions refund on paid plans.

What makes a prompt stronger?

A stronger prompt gives the model a clear role, context, constraints, decision criteria, output format, and examples or variables when needed. It tells the AI how to think, what to reject, and what a useful answer should look like.

What is an AI Skill?

An AI Skill is a packaged version of a repeatable prompt workflow. It includes when to use it, what inputs it needs, how the AI should work, what format to return, and what a good result looks like.

Build your first reusable prompt in 60 seconds.
