Most AI support platforms price like this: a monthly fee for the software, then an AI charge on top - per message, per resolution, or a quiet markup on inference. Add seats and AI add-ons, and the "try it free" pitch starts looking like a starting bid.
Bring your own key (BYOK) removes all of that. You connect your own OpenAI, Gemini, Claude, Groq, or Ollama API keys and use the full platform for $0. No markup, no meter, no lock-in. Here's why that matters and how to make the most of it.
What bring-your-own-key actually means
You already pay your AI provider for API access. With BYOK, the support platform is just software on top - it doesn't resell tokens, mark them up, or charge per resolution. You pay your provider's rate directly, and the platform is free.
On Chatonn's Free plan, BYOK includes a fully customizable chat widget, 20 FAQs, 5 RAG knowledge sources you can upload docs to, 2 team members, and analytics - with 500 conversations a month. The plan never expires.
The hidden AI markup problem
This is the part that rarely makes it into the brochure. The pattern repeats across the category: some platforms advertise "AI included" at a headline price and then add a markup on every token underneath, Chatbase caps documents and charges as you grow, and Intercom stacks Fin's per-resolution fee on top of per-seat pricing. The price you see isn't the price you pay - it's where the bidding starts.
BYOK is the cleanest way to learn what AI support actually costs: whatever your provider charges, plus $0. If you can't try a product without paying an AI markup, that's useful information before you commit to a year of it.
Why BYOK means no vendor lock-in
- Your keys, your data. The AI layer talks to providers you control - nothing is invisible inside a black box.
- Switch models anytime. OpenAI one month, Groq when you want cheaper inference, Ollama when you want everything running locally.
- Walk away free. Your cost of leaving a BYOK setup is zero. Nothing holds your conversations or your knowledge base hostage.
- Test with real traffic. Real conversations, real answers, real analytics - not a demo sandbox with sample data.
Lock-in is a pricing decision in disguise. Platforms that only work on their own metered AI lock you into their rates by default. BYOK keeps the leverage on your side.
What happens when you outgrow it
When you're ready to stop managing keys, Chatonn's Pro plan ($49/month) takes over: AI-managed conversations with no API keys needed, auto cost-routing to the cheapest capable model, unlimited team members, and up to 50 knowledge sources. You graduate from BYOK on your schedule, not on a pricing tier's schedule.
Test it for free: bring your own key at chatonn.com. If the bot answers better than your current stack, you've lost nothing but a few minutes of setup.
