I built a browser extension that puts every AI chat in one side panel

August 14, 2026

Like a lot of people, I ended up with a permanent row of pinned tabs: ChatGPT, Claude, Gemini, Perplexity. Every question meant leaving the page I was working on, and every answer meant hunting for the tab I came from. The AI was helpful; the tab-juggling wasn't.

So I built chat.cx — a Chrome and Edge extension that opens all of them in one side panel that stays with you while you browse. You can run multiple chats side by side, bring your own API keys, and ask about the page you're on without ever leaving it.

A few decisions I made along the way:

Free is the full product. The free version isn't a demo — it's everything, with a limit on how many chat tabs you can keep open. I'd rather people hit a limit after they're already getting value than hit a paywall before they've seen any.

Pay-what-you-want lifetime license. Instead of a subscription, Early Supporters pay once — an amount they choose — and get unlimited tabs plus every pro feature that ships later. That deal disappears the day pro launches, which keeps me honest about actually shipping it.

No accounts, no middleman. The extension talks to the AI services directly. I'm independent and not affiliated with any of them.

It's live on the Chrome Web Store and Microsoft Edge Web Store

I'd genuinely love feedback from this community — especially on the pay-what-you-want pricing. Would you trust a lifetime deal where you pick the price, or does it read as desperate? Happy to answer anything about the build too.

The pay-what-you-want lifetime model is definitely unusual for this kind of extension. Curious what price people actually choose when they’re given the freedom to set it themselves.

  For the few who bought the Early Supporter lifetime license, they picked the minimum rather than the suggested price :) Not surprised though.
  I see the whole PWYW lifetime thing differently. I personally don’t like subscriptions, especially for a browser extension. It’s not really a typical SaaS product; it feels more like software, so I’d rather pay for a lifetime license.
  As for the price, of course it’ll change in the future as the user base grows and more features are added over time.

    That makes sense. The fact that early buyers chose the minimum is a useful signal for how people perceive the current value.

      I don't think it says much about the current value. Anything priced PWYW ends up at the minimum, no matter how good it is. Paying more means giving money nobody asked for, which is a different choice from deciding something is worth buying. And with only a few buyers, there's not much to read into it. What I watch is conversion: someone hits the tab limit, thinks about it, and pays. That's the value signal. The amount mostly tells me about the checkout page. That's part of why the Early Supporter deal ends when pro launches. One fixed price, no guessing. Honestly the surprise is that anyone paid at all. Every feature is already free, so a license isn't unlocking features, it's just removing the limits. It's closer to support than a purchase, and this early I'll take that as a good sign.

        That’s useful context. I’d be interested in continuing the conversation beyond the thread — would you be open to sharing the best email to reach you on?
