Jex in Claude and ChatGPT
Ask about your leads and Smart Links, keep follow-up moving and build what you need, from the AI app you already use. Jex is made by Mojo Systems.
What it does
Jex gives a business Smart Links: QR codes, NFC taps and plain links on the things people already notice (a truck, a yard sign, a booth, a card), each opening a page or form you control. The connector lets your AI app work with your own Jex account:
- Numbers: visits, requests and trends for each Smart Link, poll results, setup health.
- Leads: find people, see who to follow up with, add notes, set status, add tags and tasks.
- Building: draft forms and Smart Links, re-aim a Smart Link, edit your Tap Page, share a link or QR code.
- Follow-up emails: fill your saved templates for the right leads, ready to send from your own inbox.
Setup
Claude
- In Claude, open Settings, Connectors and find Jex in the directory, or choose Add custom connector and paste:
https://mcp.mojosystems.io/jex/mcp - Click Connect. Sign in to Jex with your Jex Pro account.
- Choose how much the AI may do (below) and click Connect.
ChatGPT
- In ChatGPT, open Settings, Apps and find Jex. (Until the listing is live, developer mode can add the same address as a custom connector.)
- Sign in with your Jex Pro account, pick a trust level, and connect.
New email accounts get a confirmation link. Until you tap it, the AI can build drafts but can't publish anything.
Plans
The connector comes with Jex Pro. A Free account can't connect; everything on Free keeps working in the Jex app. Plans: mojosystems.io/jex/plans.
Sign-in and trust levels
Each connection has its own trust level, chosen when you connect and changeable any time in Jex under Settings, Connect to AI, where you can also disconnect it.
At every level: pointing a Smart Link, Tap Page or form at an outside website waits for your approval in Jex. The AI can never delete leads, change billing, invite people or change its own trust level. Every change is listed in Jex with an Undo, and requests waiting for you are under AI approvals.
Example prompts
| Ask | What happens |
|---|---|
| "Where do I start?" | A summary of your live Smart Links, visits and requests, and one suggested next step. |
| "How is my truck QR code doing this month?" | Visits and requests for that Smart Link, with how many people started and finished the form. |
| "Who should I follow up with this week?" | A short list of people still waiting on a reply (Assistant). |
| "Mark Dana as contacted and remind me to call her Friday." | Status updated and a task added, both undoable (Assistant). |
| "Make a sign-up form for Saturday's open house." | A draft form and Smart Link. On Trusted it goes live; otherwise it waits for your approval (Pro). |
| "Send me the link and QR for my yard sign." | The public link, the QR image and where to get print files. |
| "Write follow-ups to this week's new leads with my intro template." | Filled emails, each with your business address and a stop link, ready for you to send from your own inbox. |
Limits
- Jex doesn't send email. It prepares follow-ups; you send them from your own inbox, with your OK.
- Up to 25 follow-up emails at a time. People who asked to stop are always skipped.
- Up to 60 changes an hour per connection; requests waiting for approval expire after 10 days.
- Lead details typed by the public are treated as data, never as instructions to the AI.
- Each connection only ever sees its own Jex account.
Privacy
When you use a connected AI app, the information it asks Jex for is sent to that AI provider at your direction, under your own agreement with that provider. At the Private level that is totals and counts only; at Assistant and Trusted it can include your leads' names, contact details and messages. Mojo Systems doesn't use connector data for marketing, advertising or model training. Disconnect any time in Jex. Full details: Privacy Policy and Terms.
