WHAT LYRA IS

Lyra builds AI agents.

Not chats.
Not tools.
Not experiments.

You describe a clear problem.
Lyra designs a finished, purpose built AI agent you can actually use.


THE PROBLEM LYRA SOLVES

Most AI tools talk.
They don’t finish the job.

Lyra exists for one reason:
To turn clear intent into working AI.

No learning curve.
No technical setup.
No prompt engineering.


HOW LYRA WORKS

Simple by design.

  1. You explain the problem
    “I help one customer do X. I want an agent that helps solve Y.”

You can type it messy.
You can paste links or copy.
You can add a voice note summary.

  1. Lyra asks a few focused questions
    One question at a time.
    Only what matters.
  2. Lyra builds the agent
    Rules.
    Structure.
    Boundaries.
    Outputs.
  3. You receive a finished agent
    A copy ready master prompt.
    A clear agent brief.
    A quick start test.

Paste it into GPT Creator.
Your agent is live.
