Try ChatGPT on Your Kindle for Free
Want to see what AI chat looks like on a Kindle before paying for anything? You can try it right now. Takes about 30 seconds.
How to Try It
- Pick up your Kindle (or any e-reader with a browser)
- Open the browser. On Kindle it's under the three-dot menu as "Experimental Browser" or just "Browser"
- Go to companion.ink
- Start chatting
No email, no credit card, no app to install.
What You'll See
The free demo gives you a feel for how the interface works on e-ink:
- Page-based chat. Responses are broken into pages you flip through, like reading a book. No laggy infinite scrolling.
- Clean typography. High contrast text designed for e-ink, with adjustable font sizes.
- It actually loads. The interface is lightweight enough to work on the Kindle's limited browser. Unlike ChatGPT or Claude's websites, which just break.
Why Can't I Just Use ChatGPT's Website?
Short answer: the Kindle browser can't handle it. ChatGPT, Claude, Gemini, Perplexity... none of them load properly. The pages either break completely or partially load with nothing working.
companion.ink is built specifically for e-reader browsers. Same AI models, different interface. One that actually works.
What the Full Version Gets You
If you like the demo, the full version is $5/month:
- $4/month in AI credits. Enough for hundreds of messages with Claude Sonnet 4.6 or GPT-5 Mini.
- All the big models. GPT-5.4, Claude Opus 4.6, Claude Sonnet 4.6, and more.
- Switch models any time. Use a cheaper model for quick questions, switch to a premium one when you need depth.
- On-device chat history. Your conversations stay on your Kindle, not on our servers.
- Personalisation. Tell the AI what you're reading so it gives better, more relevant responses.
- Markdown rendering. Formatted responses with headings, lists, bold text.
