Jasper runs Claude Code, Copilot, Aider, Gemini and Codex side by side across your projects — on your Mac, on a server over SSH, or watched from your phone.
Email support@agent-jasper.com and we will get back to you. Include what you were doing, what you expected, and what happened instead — that alone usually saves a round trip.
This is the most common one, and it is almost always the same cause: the phone paired with the wrong machine.
The pairing panel on your desktop advertises that desktop's address. If your phone is not on the same network, it cannot reach it, so the pairing never completes and the app stays empty. To pair with a VPS, take the code from the VPS itself:
Codes are single-use and expire in ten minutes. If yours expired, just press the button again.
Check the server address the phone is using is reachable from the phone's network. A
localhost or 127.0.0.1 address only ever works on the machine itself.
For a VPS, set AI_TERMINAL_ADVERTISED_URL on the box to its public URL.
Sessions are meant to survive restarts and reconnects. If they do not, tell us how many you had, whether they were local or over SSH, and roughly when it happened — the server keeps a restore log that makes this diagnosable.
Jasper drives the CLI tools you have installed; it does not bundle them and does not resell AI usage. Check the tool runs on its own in a normal terminal first, and that you are signed in to it. Your keys stay in your own vault — we never see them.
Periods are prepaid 30-day blocks. Paying again while one is running extends it from its end rather than restarting the clock. For billing questions, or to cancel, email the address above.
Your work stays on your own machines — see the privacy policy. If you want the account data we hold, or want it deleted, email us and we will respond within 30 days.
What helps most: which app (desktop, iOS) and version, what you did, what happened, and a screenshot if the problem is visual. If it involves a terminal, say whether it was local or over SSH — the two take different paths through the code.
