The Gate / The Library / The Prompt Forge
The Prompt Forge
The machine isn't broken — it's listening. This is the game that teaches you to speak so it answers: eight chambers, forty-nine trials, and a live coach that scores every prompt you forge, not what you meant to forge.
Eight chambers. Seven keepers.
Each chamber holds one durable law of the craft, kept by a master who won't let you pass on charm.
The First Furnace
Where every wizard takes their first strike — structure, clarity, and the weight of a word that works.
The Hall of Masks
A mask changes the voice — never the knowledge. Sefa teaches which to wear, and when to wear none.
The Iron Blueprint
Format, constraint, and the Law of Slag — a word that does no work is not neutral. It is noise.
The Chain Works
One strike is a prompt. A sequence is a machine. Orin forges the links between them.
The Crucible
Patterns, examples, and the permanent layer — the rules that outlive any single session.
The Wild Forge
Image and invention — a scene told in sentences, not keywords shouted at the fire.
The Obsidian Mirror
The trials run backward here. Read the result, and reconstruct the hand that forged it.
The Ember Archive
No trials. A candle, five letters, and the history the other chambers won't tell you. You earn this room.
What you carry out.
49 trials across 8 chambers
42 standard trials plus 7 inverted ones that break the write → run → seal loop — repairing broken prompts, reconstructing a prompt from its output, and spotting which prompt forged a given result.
A coach that's awake — 2,000 runs included
Every prompt you submit is scored by a live AI coach against specific criteria, not a canned checklist. No API key required to begin.
56 skills, 13 achievements, 10 ranks
XP-driven progression from The Unlit to The Grand Forgemaster, with achievements earned at real milestones — not for showing up.
21 hidden Forge Shards
Lore fragments gated on genuine performance — a masterwork score, consistency across distinct trials, or precision under a word limit. Grinding one trial won't unlock them.
The Ember Archive
A reading room of five letters on why prompting techniques expire and what never does — no trials, just the deeper story, earned.
Runs anywhere the fire reaches
A single browser-based experience — desktop or mobile, nothing to download. Add it to your home screen to carry it with you.
Don't take the Forge's word. Face a trial.
A real Trial of Eyes waits at the door — free, no account, no catch. Read what the machine made and name the hand that made it.
Face the Doorstep Trial ↗Before you cross.
Do I need my own AI API key?
No. Coaching is included and already paid for. If you ever burn through the 2,000 included runs and want more, you can plug in your own key as an optional fallback — never required.
Is this a subscription?
No. It's one payment, and it's yours to keep — no recurring charge, no expiring license.
What do I get right after I buy?
An access link and your personal license token, sent to the email you check out with — usually within minutes, always within 24 hours.
Does it work on my phone?
Yes. It's a single browser-based experience that works on desktop and mobile, with nothing to download. You can even add it to your home screen so it opens full-screen like an app.
Is this made or endorsed by Anthropic?
No. The Prompt Forge is an independent product built to teach prompting for AI models generally. Claude™ and Anthropic™ are trademarks of Anthropic, PBC, and this product is not affiliated with or endorsed by Anthropic.
