Every timeMust hit the same standard without you? Have it built.
£997Once, for the built path, plus your own AI seat.

The choice

Which one you need.

Buy a seat if

  • One person does the job.
  • The job is simple.
  • A miss is cheap to fix.
  • You check every output.

Have it built if

  • It must hit the same standard every time.
  • You cannot check every run.
  • Your files and past jobs sit behind the work.
  • Your team must run it when you are out.
The difference

You're not buying AI. You're buying the system that holds the standard without you in the room.

How it works

The built path.

  1. We build it

  2. We test it on your work

  3. It moves to your seat

  4. Your team runs it

Questions

Straight answers.

  • Should I just buy ChatGPT?

    If one person does a simple job and you check every output, yes. If it must hit a standard without you, have it built.

  • What does Greycell charge for the built path?

    £997 once for one job, plus your own AI seat. Full refund if it isn't live by day 10.

  • Do you lock me into one AI brand?

    No. After test, the agent moves onto your own Claude or OpenAI subscription.
