ChatGPT and other web AI apps

Some AI apps run in your browser rather than on your computer: ChatGPT, Perplexity, Manus, Hermes, and many newer web AI apps. Lune connects to them as a custom connector — you add Lune once, sign in through your browser, and the assistant gets the same research abilities.

The general flow

Every web AI app uses a similar four-step flow:

  1. Open the AI app's Settings → Connectors (or Custom apps, or Plugins — the label varies).
  2. Click Add custom connector and paste the URL we give you on the dashboard's Install page.
  3. Sign in to Lune in the small browser window that pops up. This proves it's really you and connects the assistant to your Lune account.
  4. Approve the connection. The assistant now has every Lune ability.

The dashboard's Install page has illustrated, step-by-step recipes for each supported AI app — the wording differs slightly by vendor.

App-specific notes

ChatGPT. Lune is configured as a ChatGPT custom connector / app. Inside ChatGPT go to Settings → Connectors → Add custom connector, paste Lune's URL, sign in, approve. Once connected you'll see Lune listed alongside ChatGPT's built-in tools.

Perplexity. Open Customize → Manage Connectors → + Custom Connector and follow the recipe on the Install page. Perplexity asks you to upload Lune's icon and to paste an API key — the recipe gives you a downloadable icon and walks you through generating a key.

Manus. Settings → Connectors → + Add Connectors → Custom MCP → Import by JSON. Paste the snippet from the Install page; Manus does the rest.

Hermes Agent and others. The "Connect by URL" recipe at the bottom of the Install page is the universal recipe — paste the URL into your app's connector settings and sign in.

Common questions

Do I have to give the AI app my password? No. You sign in to Lune through your normal browser, the same way you sign in to the dashboard. The AI app never sees your password.

Can I revoke an AI app's access? Yes. The Credentials page shows every connected app and lets you revoke any of them. Revocation is immediate.

Is my data shared with the AI app vendor? Lune sends back what your assistant asked for — search results, paper text, citation lists. Whatever the AI app does with that response is up to its own privacy policy. We don't share your account details, billing info, or anything else with the vendor.

My AI app isn't in the recipe list. If it supports the open custom-connector standard (most newer ones do), the "Any other AI app" recipe on the Install page works. Paste Lune's URL into your app's connector settings; it'll lead you through the sign-in.
