How Ji4 changes your support stack
Most support tools are built for service desks. Ji4 is built for the engineers who fix the problem.
Six deletions. One workflow. Ship the diff.
One shared inbox for every customer conversation
Email, chat, and portal messages land in a single triage view the whole team can work. Assign, snooze, and reply without leaving the thread.
- Assignment, snooze, and internal notes
- Full conversation history in one place
- Keyboard-first, like the tools you already use
Turn any ticket into a Linear issue in one keystroke
Spot a bug in a conversation and open a Linear issue without switching tabs. The ticket and the issue stay linked, both ways, for good.
- One keystroke from conversation to issue (⌘ + L)
- Team, project, and labels pre-filled (AI Assisted)
- The link never goes stale
Status flows both ways, automatically
When engineering moves the issue, the customer hears about it. No status meetings and no copy-paste updates. The loop closes itself.
- Issue status mirrors back to the ticket (Not the user)
- Customers notified when their fix ships (Email, chat, portal)
- Nothing to remember, nothing to chase (real time sync)
A portal your customers actually want to use
A clean, on-brand space where customers raise issues, track progress, and see what shipped, without an email thread in sight.
- Self-serve end user issue tracking
- Branded, fast and secure, no login friction
- API first for embedding in your own app or site
From customer message to shipped fix
A ticket becomes a linked Linear issue in one keystroke, and status flows back to the customer automatically as engineering moves it.

Frequently asked questions
Simple answers about plans, billing, and your free trial.
What is Ji4?
Ji4 is customer support built for engineering teams. It gives you a shared inbox for customer conversations that connects directly to Linear, so bugs become issues in one keystroke and status flows back to the customer automatically.
Who is Ji4 for?
Ji4 is built for software teams that already track engineering work in Linear and want customer support to plug straight into that workflow, not sit beside it in a separate tool. It suits small and mid-sized, engineering-led teams, from an early-stage startup to a scaling product company, where the person who can fix a bug is close to the person answering the ticket.
How does the Linear integration work?
Connect your Linear workspace with OAuth, and any conversation can become a linked Linear issue. When engineering moves that issue, the status syncs back to the ticket and the customer, with no copy-paste and no status meetings.
Is Ji4 a Zendesk or Intercom alternative?
Yes. Ji4 covers the shared inbox and support workflow you'd expect from Zendesk, Freshdesk, or Intercom, but it's built for teams that ship on Linear rather than for a standalone support department.
Do my customers need a Linear account?
No. Customers reach you over email, chat, or the Ji4 portal. The Linear connection is entirely on your side. Customers never see it, they just get faster answers and clear status.
Is there a free trial?
Every plan starts with a 14-day trial. No credit card is required to start, and you can cancel anytime.
How much does Ji4 cost?
Pricing is seat-based across Basic, Pro, and Enterprise tiers, priced by team size rather than ticket volume. See the pricing page for the full breakdown.
