How can we help?

SJMap turns a natural-language description of a software system into a structured, visual architecture blueprint - nodes for components, edges for connections, plus tech-stack suggestions. You can then iterate on the canvas and export a Master Prompt that a coding agent can use to build the project.

From the Home page, type a one-paragraph description of the system you want into the prompt box and click GENERATE. The AI returns a complete architecture; you'll land on the workspace canvas where you can edit it, refine it, or export a Master Prompt.

Yes. Every node and edge on the canvas is draggable and editable. Click a node to open the inspector panel; edit fields like title, tech stack, and description. The constructed prompt at the left re-compiles automatically as you change the blueprint.

It compiles your blueprint into a structured Master Prompt that you can hand to any AI coding agent (Cursor, Copilot, Claude, etc.) so it understands what to build. Click the GENERATE AI AGENT PROMPT button to copy the full Markdown to your clipboard.

Tokens are the platform's metering currency. Each blueprint generation costs 50 tokens. You get 100 free tokens when you create an account - enough for 2 blueprints. When you run out, you can buy more from the Shop.

One blueprint generation = 50 tokens. Editing, viewing, exporting, and sharing are free - tokens are only spent when the AI is invoked to produce a new structure.

Your tokens are automatically refunded. The system spends tokens up front, then writes a compensating REFUND entry to your ledger on any failure path. You'll see both the original SPEND and the REFUND in your history.

If you're trying things out, the Spark Pack ($1.99 / 1 blueprint) is the smallest purchase. The Architect Pack ($14.99) is the most popular and includes a 20% bonus. The Studio Pack ($39.99) is our best per-token value.

The current build runs a mock checkout for evaluation. Before going to production, payment is wired through Stripe Checkout - your card details never touch our servers.

Click Login in the top-right corner, then choose Create account. You can use email + password or sign in with an OAuth provider (Google, GitHub).

Yes. Visit Account, Settings, Delete account. This cascades through your blueprints, history, and ledger entries - the action cannot be undone, so we recommend exporting any blueprints you want to keep first.

Shop, View transaction history (link at the bottom of the storefront), or directly at /tokens/history. The page lists every PURCHASE, SPEND, REFUND, and GRANT row with a running balance.
