Use Flywheel inside your own ChatGPT or Claude account. This shows manual setup before directory approval. Public comparisons need no Flywheel account. In Claude, open Customize, Connectors, Yours, then Add custom connector. Enter a name and paste the exact calculator server URL shown on screen. Choose Sign in when needed and Register automatically, then Add. In a new chat, open the plus menu, choose Connectors and enable Flywheel. In ChatGPT, open Plugins, Add, then Add custom MCP server. Enter the name and the same server URL. Choose OAuth or no authentication. Open Advanced OAuth settings. Use Dynamic Client Registration. Keep openid as the default scope and offline_access as the base scope. Disable OIDC and clear its extra scopes. Create the private plugin. Choose Use without an account for public comparisons. For member features, sign in to Flywheel with your own account and emailed code. Never put that code in the AI chat. Check the Flywheel consent page and the return destination. Allow calculator access only if you agree. It permits membership checks and calculations, not saved plans or GoMining transactions. Select Flywheel in your chat and ask what you want to compare. Confirm the miner kind and the planning date, not just the purchase date. Answer the relevant questions in stages. This confirmed fictional example compares maintenance for one ordinary miner. The actual result is about eighty cents without GOM payment and sixty-three cents with it. These are assumed costs, not a live quote. Compare loose GOM and locks, or BTC, GOM and TH reinvestment. Check all remaining assets and warnings. Unknown balances must stay unknown; the model does not rank whole-portfolio returns. A free Basic account does not unlock PLUS. Eligible PLUS and Founder accounts can use advanced calculations, within the connector limits. Disconnect in your AI client to revoke that connection.
