For ChatGPT, Claude and any MCP client
Run your links from inside ChatGPT
openin.app is where a creator's links live: links that open the real app instead of an in-app browser, a page that holds every one of them, and numbers on every tap. Connect it to your assistant and it can make links, build your page and read your stats — in plain language.
What you are connecting
Not a shortener. A shortener makes an address smaller; an openin.app link changes what happens when it is tapped — and the rest of the product is built around that tap.
Links that open the app
Tapped inside Instagram, TikTok, Facebook or WhatsApp, an openin.app link opens YouTube, Spotify, Amazon, Instagram or TikTok itself — logged in — instead of the in-app browser. That is the difference between a view and a subscriber, a listen and a follow, a look and an order.
A page for all of them
openin.app/@you holds every link with the same app-opening behaviour, plus social icons, nine themes and a QR code. Free, unlimited, no ads.
Numbers on every tap
Every link counts its taps. Pro breaks them down by day, source app, device and country, so you know which post did the work.
Shopping links that keep your tag
An Amazon link keeps your Associates tag byte-for-byte and opens the Amazon app where it is installed. Your commission stays yours.
A second chance at every tap
When a viewer comes back from the app, the tab they left is still open — with your other links on it, not a blank page.
Built to be operated by an assistant
A remote MCP server with eleven tools, six that read and five that write, and a one-request address any assistant can use to make a link without an account.
What your assistant can do once connected
Almost everything you can do from the dashboard, said out loud. Eleven tools sit behind it — six that read, five that write — and the assistant asks before it changes anything. Deleting a link stays in the dashboard.
Make and change
- “Make an openin.app link for my new video and put it at the top of my page.”
- “Add my Amazon storefront to my page and call it ‘My camera kit’.”
- “Switch my page to the Midnight theme and add my TikTok.”
- “Claim @yourname for my page.”
Ask
- “Which of my links got the most clicks this week?”
- “Where is my traffic coming from — Instagram or TikTok?”
- “What’s on my openin.app page right now?”
- “How many taps did my channel link get in total?”
Connect in a minute
openin.app is a remote MCP server. Add it once in your assistant, sign in with your openin.app account, approve — and it is connected until you say otherwise.
No API key exists to paste, and nothing is installed. Every connected app is listed under Account → Integrations, where one click disconnects it.
- 1.Copy this address:
https://www.openin.app/mcp - 2.Claude: Settings → Connectors → Add custom connector → paste it.
ChatGPT: Settings → Connectors (developer mode) → add it. - 3.Sign in with your openin.app account — Google or the email link — and approve.
- 4.Say what you want done. Start with “what’s on my openin.app page?”
What it will and will not do
Only your account, only while connected
The assistant acts as you, under the same rules as the dashboard, and sees nothing that is not yours. Disconnect it any time under Account → Integrations.
Every change is one you asked for
Assistants confirm before running a tool that changes something. There is no delete tool: the assistant can take a link off your page, which is reversible, but deleting a link for good stays in your dashboard.
Addresses are promises
A link never changes where it points — everyone who already has it would be sent somewhere else. The assistant makes a new link instead, and warns before changing a slug or a handle.
Pro stays Pro
Per-day and per-source breakdowns, custom slugs, the Pro themes and hiding the badge work exactly as they do in the dashboard: on Pro, and with an upgrade pointer otherwise.
No account? Ask for a link anyway
Any assistant that can fetch a web address can make an openin.app link in one request — no account, no key, no connector. Paste a destination and ask.
The same destination always returns the same link, so it is safe to ask twice. To see click counts later, sign in at openin.app and the link is yours.

Questions people ask
- What can ChatGPT or Claude do with openin.app?
- Once you connect your account, the assistant can make links that open the real app, give them titles, put them on your bio page and reorder it, change your page’s name, bio, theme and social icons, and claim your handle. It can also answer questions from your own numbers: which link did best this week, where your taps come from, what is on your page.
- Is openin.app just a link shortener?
- No. A shortener makes an address smaller. An openin.app link changes what happens when it is tapped: inside Instagram, TikTok, Facebook or WhatsApp it opens the real app, logged in, instead of the in-app browser. Around that link sit a bio page that holds every link, analytics on every tap, affiliate-safe shopping links, and the assistant connection on this page.
- Can ChatGPT make an openin.app link without an account?
- Yes, if it can fetch a web address. Ask it for an openin.app link for a YouTube, Instagram or Amazon URL; it fetches the one-request address at the end of this page and hands you the link. No account or key is involved, and the same destination always returns the same link.
- Can the connector delete my links?
- No. There is no delete tool. The assistant can take a link off your page, which is reversible, and deleting a link for good stays in your dashboard. A link’s destination can never be changed either — the assistant makes a new link instead. And assistants confirm before running any tool that changes your account.
- Which assistants work?
- Claude and ChatGPT both support remote MCP connectors with sign-in, and any other client that supports remote MCP servers over OAuth 2.1 connects the same way. There is no API key to paste anywhere.
- Does it cost anything?
- No. Connecting is free, and so are unlimited links and the page. Per-day and per-source breakdowns, custom slugs, the Pro themes and hiding the openin.app badge are part of Pro, the same as in the dashboard.
