New: pay what you like on every OS Brain. $49, $25, $10, or free. You decide. Browse →
Drops into Claude · ChatGPT · Gemini · Grok

Give your AI a brain, not a prompt.

An OS Brain is a zip of eleven files. One orchestrator reads your situation, hands it to the right specialist, and refuses to return an answer that skipped a step. Built for the jobs where a sloppy answer costs real money: the quote, the negotiation, the interview, the launch.

THE QUOTE · live rungated pipeline
YouClient wants full brand + site. Said "around 8 to 10k". Need a proper quote without underpricing.
THE QUOTELead is real, anchored low. Scope bounded: identity system plus a five-page site. Floor locked at €14,800. Quote built. When they push on price, you say: "The 8 to 10k version is a logo and a template. You asked for a brand."
Gate 03 refused to build the quote until the floor was set.

The difference

Prompts break. Brains don't.

A prompt pack hands you a folder and wishes you luck. A brain owns the job from intake to output.

✕A prompt pack

Separate files. You pick the one you hope is right, paste it in, and nothing stops the model inventing scope or skipping a step.

  • You choose the file every time
  • No enforced order
  • Drifts on the second run
  • Quality depends on how well you prompted today

✓An OS Brain

One orchestrator, ten specialists. You describe the situation. It classifies the job, routes it, and gates the output before you see it.

  • You describe the situation in plain English
  • Routing and chaining happen on their own
  • Gates block skipped steps
  • Same process on run fifty as on run one

$199THE ARCHITECT

The brain that builds brains. Name the job you repeat, it interviews you and ships a finished brain. The one fixed price in the range, because it makes all the others.

See THE ARCHITECT14-day money-back guarantee

Why free is allowed: copies cost us nothing, and people using these beats people thinking about buying them. If a brain earns its keep on a real job, come back and pay what it was worth on the next one.

Judge it yourself

See the standard before you choose a price.

Ask for one free SKILL.md on any job you repeat. We write it and send it, up to twenty a day. It's one file, not a brain, but it's written to the same standard as every file in the range.

Questions

Before you choose a price.

Is pay what you like for real?

Yes. Pick free on the price selector and check out. The zip is identical at every price. If it earns its keep, come back and pay what it was worth on the next one. THE ARCHITECT is the one fixed price.

What do I actually download?

A zip. One orchestrator file, ten specialist files, an install guide and a licence. All plain-text SKILL.md files you can open and read.

Which AI do I need?

Claude (Projects), ChatGPT (a Custom GPT), Gemini (Gems) or Grok. Upload the files and start. No API keys, no code, no developer account.

Is it a subscription?

No. One payment, whatever size you chose, and the files are yours. Use them on as many jobs as you like.

How is this different from a prompt pack?

A pack gives you files and leaves the sequence to you. A brain has a router and gates on top, so the steps run in order and nothing gets skipped. That's the part a folder of prompts can't do.

What if I paid and it wasn't worth it?

Email info@promptleadz.com with your order number within 14 days of purchase and we refund in full. No forms, no arguments.

Stop prompting. Start delegating.
