By Kevin · Every plan and price checked on 14 November 2026 Chatbox AI, the multi-model client from chatboxai.app (not the support-chat widget with a similar name), is popular because it takes your own API keys on desktop and phone. People look for alternatives when they want chats that sync across devices, more than chat in the same app, or top models without the $19.99 Pro plan. Zemith Plus ($15.99/mo) is our pick: it runs your own OpenAI, Anthropic and Google keys next to 1.5M monthly credits, with deep research, Office files and Creative Studio built in. TypingMind, Pal Chat and LibreChat are cheaper if all you need is a chat window for a key you already pay for. ## Zemith is the Chatbox alternative that runs your own keys and credits side by side, with the tools built in. - Add your own OpenAI, Anthropic or Google key on Plus ($15.99/mo) or Pro ($29.99/mo): those chats bill to your provider account and use no Zemith credits. - A key unlocks that provider's top models above your plan: Claude 5.5 Opus on Plus with an Anthropic key. Other providers keep running on credits. - Deep research with cited reports, finished Word, PowerPoint, Excel and PDF files, and Creative Studio for images and video (Nano Banana, Flux 2, Veo 3.1, Kling, Seedance 2.5). - Native iOS and Android apps and the web app, with the same chats on every device.

Zemith Plus ($15.99/month) for most people: it runs your own OpenAI, Anthropic and Google keys next to 1.5M monthly credits, syncs chats across web, iOS and Android, and includes deep research, Office files and Creative Studio. ### Is there a Chatbox alternative that syncs chats across devices? Yes. Zemith stores chats in your account, so they show up on the web and in the iOS and Android apps. TypingMind offers sync as a separate paid cloud service, and LibreChat syncs if you host it on a server you can reach from every device. ### Can I use Claude Opus with my own API key on Zemith? Yes. On Plus or Pro, add your Anthropic key under API Keys and Claude 5.5 Opus runs on it, billed by Anthropic, even though Opus on credits needs Pro. If the key stops working, the chat stops with an error instead of switching to credits. ### Which Chatbox alternative is cheapest? For a chat-only client with your own key, LibreChat is free software if you host it yourself, Pal Chat Pro is $6.99 on the US App Store, and TypingMind is a one-time $39 to $99. Chatbox's own free route and $3.99 Lite plan are also cheaper than Zemith. ## Try Zemith free: your own keys, credits and every tool in one app. [Start free on Zemith](https://www.zemith.com/app) ## Read these next to compare the other tools. - [Chatbox AI pricing: Free, Lite, Pro and Pro+](https://www.zemith.com/en/learn/chatbox-pricing) - [Chatbox AI review 2026: ratings, strengths and limits](https://www.zemith.com/en/learn/chatbox-review) - [Bring your own OpenAI, Anthropic or Google API key to Zemith](https://www.zemith.com/en/features/bring-your-own-api-key) - [Use Claude Opus with your own API key](https://www.zemith.com/en/contents/use-claude-opus-with-your-own-api-key) - [The best TypingMind alternatives in 2026, ranked](https://www.zemith.com/en/learn/typingmind-alternatives) - [LibreChat alternatives compared](https://www.zemith.com/en/learn/librechat-alternatives)
