On a tight budget
What is the cheapest AI support tool that actually works?
Per-resolution pricing charges you more the better the AI performs. These have predictable bills.
19 platforms qualify
Filtered on stated criteria, not on our opinion. Anything we have not tested is marked, and every figure is a vendor claim until it is.
eesel AI
Not testedTrains on your existing docs and tickets and works inside the help desk you already run, instead of replacing it.
Chatbase
Not testedPoint it at your site and get an embeddable agent in an afternoon. The low-effort end of the category.
My AskAI
Not testedDeliberately cheap deflection layer that hands off to whatever live chat you already run.
Chatwoot
Not testedOpen-source support platform you can self-host, increasingly paired with n8n for the AI layer.
Botpress
Not testedVisual studio for building agents with explicit flow control, for teams that want to see the logic.
Wonderchat
Not testedFlat-rate site agent with deliberately transparent pricing in a category that mostly hides it.
Quickchat AI
Not testedMultilingual-first agent aimed at teams supporting many languages without native speakers.
HubSpot Breeze
Not testedOnly worth evaluating if your CRM is already HubSpot. Then the context it has is hard to match.
Tidio Lyro
Not testedOne of the few genuinely cheap autonomous agents, bundled with live chat and a basic help desk.
HappyFox
Not testedOffers a genuine unlimited-agent plan, which is rare in a category that mostly charges per seat.
Freshdesk with Freddy AI
Not testedCheaper than Zendesk with a comparable feature list. The trade shows up in depth rather than breadth.
Help Scout
Not testedChosen for simplicity rather than power. AI drafts and summaries, not an autonomous agent.
Zoho Desk
Not testedThe cheapest credible help desk with published per-agent pricing and a genuine free plan.
Front
Not testedTreats support as team email rather than tickets, with AI on top as drafts and summaries.
Hiver
Not testedTurns Gmail into a help desk. Narrow by design, and cheap because of it.
Re:amaze
Not testedHelpdesk and live chat for e-commerce brands, now part of GoDaddy's portfolio.
DevRev
Not testedConnects support tickets to the product backlog, aimed at teams where engineering fixes the ticket.
Zendesk QA
Not testedFormerly Klaus. Auto-scores every conversation and now grades AI agents alongside humans.
Amazon Connect
Not testedUsage-priced contact centre from AWS with agentic AI bundled. Cheap to start, complex to run.
Why we built this page. The most common complaint found anywhere. r/SaaS: 'My Intercom billing shot up by 120%' (70+ comments). r/CustomerSuccess describes per-resolution pricing as structurally punishing.
