Connect Contextick to ChatGPT

Contextick is in ChatGPT's plugin directory, so connecting it is a search and a click — on any plan, the free one included. Set it up once and OpenAI's Codex has it too: plugins are shared across ChatGPT and Codex, so there's nothing extra to do there. Here's the whole path.

What you'll need

Any ChatGPT plan, including Free. The plugin directory is there on every plan — no Plus or other paid subscription, and nothing to apply for.
ChatGPT on the web or the desktop app. The plugin directory isn't in the mobile app — set it up on a computer. Once it's connected, that's a one-time thing.
A Contextick account. You'll sign in with Google during the connection, so no API key is needed — ChatGPT's plugins use OAuth and don't accept a pasted key.

One thing to expect: ChatGPT asks you to confirm before an action that writes data. So each time you ask it to save something to Contextick, you'll get a confirmation prompt. That's ChatGPT's behaviour, not something we can turn off — you can approve a tool for the rest of a conversation to cut down on the clicking.

Steps

In ChatGPT, open Settings → Plugins, or the Plugins entry in the sidebar.
Search for Contextick and open its listing — this link goes straight to it. Then choose Install plugin.
Connect it. ChatGPT sends you to Contextick to sign in with Google and approve access. That approval is what links the plugin to your knowledge — nothing to paste, nothing to copy.
Contextick is now available in ChatGPT. Bring it into a conversation by typing @Contextick, or from + → More in the composer.

Check it worked

Test it in two parts, and make the second part a new chat. If you ask in the same conversation, ChatGPT can answer from what you just said without ever calling Contextick — so a broken connection would still look like it worked.

Save something you'd actually want back. At the end of a conversation where you worked something out, say: "@Contextick save what we landed on for the kitchen renovation budget." Confirm when ChatGPT asks — that's the write confirmation.
Open a new chat and ask: "@Contextick what did we land on for the kitchen renovation budget?"

If it comes back in the new chat, you're connected — and you've just seen the point of it: you didn't have to explain any of it again. Anything you save here is available in Claude or any other AI you connect to Contextick.

If it doesn't show up

You can't find Contextick in the directory. The directory itself is on every plan, but whether you can install a given plugin also depends on your workspace and your region. On a Business, Enterprise, or Education workspace, an owner controls which plugins members may install — if the button is greyed out or says the plugin is disabled by an admin, that's who to ask. You do not need to upgrade your plan.
ChatGPT never offers Contextick. Call it directly: type @Contextick, or pick it from + → More in the composer, and then ask — "save this to Contextick".
Saving does nothing. Look for the confirmation prompt — writes wait on your approval, and it's easy to miss.
Deep research or agent mode can't see it. Those modes handle plugins differently. Use a normal chat.
