What's different about ChatGPT vs. Claude

Claude Desktop, Cursor, and VS Code all connect using a connector URL with your API key baked in (?apiKey=fmk_...) — see the Getting Started guide. ChatGPT works differently: Finmagine is a listed app in OpenAI's app directory, so there's no URL to copy and no API key to paste. You connect entirely from inside ChatGPT, and it always uses a real OAuth login — the same login/consent screen described in the Connected Apps & Auth Types guide.

The one-line version: If you're on ChatGPT, you never touch an API key at all — you log into Finmagine once, on Finmagine's own site, and approve access.

Connect in three steps

Open Finmagine's ChatGPT listing directly → — or follow the three steps below to find it from inside ChatGPT.

Step 1

Find Finmagine in ChatGPT

Inside ChatGPT, search for "Finmagine" in the apps/connectors directory — or use the direct link above.

Step 2

Click Connect

ChatGPT redirects you to Finmagine's login and consent screen — no manual URL or key entry.

Step 3

Sign into your Finmagine account and approve the requested access. You're connected.

The real consent screen — every requested scope is spelled out in plain language before you approve anything.

Once connected, the app shows up on your Connected Apps page labeled "ChatGPT" — with a Disconnect button if you ever want to revoke access.

What tier does my ChatGPT connection get?

Your ChatGPT connection uses your existing Finmagine account automatically — if you already have an API Pro or API Max subscription (or a Professional/Premium web plan), the connection provisions at that tier from the start. If not, it starts on the free tier, same limits as any other free API key. Upgrading later — through the developer portal or your account subscription — applies automatically to your ChatGPT connection too, with no need to reconnect.

Provider keys stay out of ChatGPT entirely. Finmagine never asks ChatGPT for your saved Groq/DeepSeek/Gemini/etc. keys, and ChatGPT can't save one on your behalf either. Manage those separately on AI Keys — if a tool needs one you haven't saved, it'll point you back there.

Starter prompts

Try these once connected:

"What's the market breadth trend for Indian stocks over the last 20 days — broad advance or selective market?"

"Pull the top momentum stocks by RS rating — which sectors are dominating?"

"Screen for profitable mid-cap Indian stocks with low debt and strong momentum."

"Give me Reliance Industries' AI-generated quarterly summary and concall decoder — any red flags in management's tone?"

"Which AI providers do I have connected?"

The last one checks your saved BYO provider-key status without ever exposing the key itself — useful before asking ChatGPT to run an Investment Committee analysis, which needs one connected.

Quick reference

Do I need a Finmagine API key to use ChatGPT?

No. The OAuth login/consent flow replaces the API key entirely for ChatGPT connections. API keys are only used for the URL-based connector setup (Claude Desktop, Cursor, VS Code).

Why does it show up as "ChatGPT" and not "Finmagine" on my account?

See the Connected Apps & Auth Types guide — Connected Apps lists the outside app connecting to your account, the same convention Google and GitHub use.

Can I disconnect it later?

Yes — click Disconnect on Connected Apps, or remove the connector from ChatGPT's own settings. Either one revokes access immediately.
