AI Prompt Generator
Describe the AI assistant or system prompt you need.
AI Game Builder generates a production-grade instructions + knowledge pack from it,
using the same methodology behind our own stacks. Runs on your own Anthropic API key — you only pay for
the engineering, not per-run fees to us.
Simple
€9.00
One focused instructions.md — a single-purpose prompt (e.g. a support-reply assistant, a data extractor).
Standard
€29.00
instructions.md + a knowledge.md reference file — a multi-step assistant with defined rules and examples.
Advanced
€79.00
A phased operating protocol (like PromptForge's own stacks) — planning phase, ordered steps, quality bar.
Expert
€199.00
Full multi-agent / multi-mode system: phased protocol + large knowledge base + edge-case handling.

- Use it in Claude Projects, the API, or any AI coding tool you like
FAQ
- Do I need my own API key?
- Yes — generation runs on your own Anthropic API key, added once in your account settings. You pay us
for the engineering; the model usage itself is billed directly by Anthropic at their standard rates.
- What do I actually receive?
- An instructions file (system prompt / operating protocol) and a knowledge file (reference material),
the same pairing that powers every stack in AI Game Builder.
- Can I see something before paying?
- Yes — a free opening excerpt is generated so you can judge the direction and quality first.
- How is the price decided?
- By complexity tier, shown above — not a flat fee regardless of how much work the brief actually needs.
