The most intuitive way to run customer support — on an AI you own.
A full helpdesk — shared inboxes, tickets, and a public help center — built for lean B2B SaaS teams who'd rather bring their own AI key than rent someone else's by the resolution. Start on a free-tier key and the AI costs you $0.
One flat price per agent — no per-resolution fees, no AI markup, no metering. The AI bill goes straight to your provider, never through us.
Free 30-day trial, no card required. Founding-member pricing — lock your rate for life. Free AI tiers are rate-limited; heavy volume needs a paid key, still at cost and never marked up.
The AI runs on your key — from $0
Start on a free-tier key and your AI responses cost nothing. One flat price per agent — never a per-resolution fee, never a markup on the AI.
An AI that knows your business
Replies are grounded in your help center and saved replies — not a vendor's generic model. Your AI, your data, your customers. Leave anytime; nothing's locked in.
A helpdesk you learn in a day
A calm, focused inbox your team actually likes using — not a sales-gated enterprise suite. No demo calls, no contracts, no sprawl.
Bring your own AI key — even a free one
Connect an AI key you own. Grab a free-tier key and your AI responses cost $0; use a paid key and you pay your provider directly — pennies per ticket, never a markup. Either way, AI usage never changes what you owe Kerux — it was never our line item to bill. See the 2-minute setup →
The AI bill goes straight to your provider — we never see, mark up, or meter it.
Per-resolution billing
Spikes with ticket volume
Kerux, flat per agent
Per agent — no usage spikes
Support software for people who hate AI pricing
No per-resolution charges. No AI usage metering. No mandatory add-on. One flat price per agent — your total is just your agent count times that price, so it moves only when your team does, never when your AI gets busy.
Calculate your savingsEverything a support team actually needs
A clean, calm helpdesk with the AI running on your key — not our meter. Here's what's built in, on every plan.

Kerux is early — and the first teams in get the founding rate. The per-agent price you start on stays yours for as long as you're a customer, even as we add features and raise prices later. No card to start.
Three tiers. One flat per-agent price each.
No volume tiers, no per-resolution surprises — and the AI runs on your key, from $0.
