# Chatbox AI costs $0 to $39.99 a month, and the top models start at $19.99.

By Kevin · Every price checked on chatboxai.app/en/pricing on 14 November 2026

Chatbox AI, the desktop and mobile AI client from chatboxai.app (not the customer-support chat widget with a similar name), has a Free plan and three paid plans: Lite at $3.99, Pro at $19.99 and Pro+ at $39.99 a month, or $3.50, $16.70 and $33.33 a month billed yearly. Lite only reaches the standard models, so Claude Opus, GPT 6.1 Sol and Gemini 4 Argon need Pro, and unused compute points are cleared at every monthly reset. You can also skip the plans and use your own API key. Zemith Plus is $15.99 a month with 1.5M credits, and it lets you add your own OpenAI, Anthropic and Google keys next to those credits, so Claude 5.5 Opus runs on your Anthropic key from Plus.

## Zemith Plus puts credits and your own API keys in one app for $15.99 a month.

- Plus is $15.99/month ($179.88/year) with 1.5M credits a month for GPT, Claude, Gemini, Grok, DeepSeek and more, with no setup.
- Add your own OpenAI, Anthropic or Google key on Plus or Pro: those chats are billed to your provider account and use no Zemith credits, and a key unlocks that provider's top models, such as Claude 5.5 Opus, even on Plus.
- Built-in 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 plus the web app, with your chats in your account on every device.

- **Chatbox Pro (monthly):** $19.99/mo (_12M compute points, the advanced models, 100 images a month; no video generation listed_)
- **Zemith Plus:** $15.99/mo (_1.5M credits + your own OpenAI, Anthropic or Google key side by side · deep research, files, Creative Studio_)

## Three things in Chatbox's plan rules worth reading before you pay.

### The models people come for start at Pro, not Lite.

> “Unlock more advanced model capabilities with Pro and above” — [Chatbox pricing page](https://chatboxai.app/en/pricing), Official plan comparison, Checked 14 Nov 2026

**On Zemith:** Lite's $3.99 covers standard models such as GPT 5.6 Luna, Claude Haiku 4.5 and Gemini 3 Flash. On Zemith Plus ($15.99) you get Claude 5.5 Sonnet, Grok and the other paid models on credits, and adding your own Anthropic, OpenAI or Google key opens that provider's top models, Claude 5.5 Opus included, without moving to Pro.

### Unused compute points don't carry over.

> “If you have remaining quota, it will be cleared on the reset date and you'll receive new quota.” — [Chatbox Quota & Usage guide](https://chatboxai.app/en/guide/chatbox-ai/quota), Official quota rules, Checked 14 Nov 2026

**On Zemith:** Zemith's monthly credits also reset, but top-ups (from $10 for 800k credits) never expire. Chatbox's add-on packs last 3 months and are marked non-refundable. And on Zemith, chats on your own key use no credits at all.

### The knowledge base and MCP tools are desktop features on Pro and up.

> “Knowledge Base is a feature exclusive to the desktop app, which allows AI to understand and search your private documents.” — [Chatbox AI Service FAQs](https://chatboxai.app/en/help-center/chatbox-ai-service-faqs), Official help center, Checked 14 Nov 2026

**On Zemith:** Zemith Library projects hold up to 50 sources on paid plans (PDF, DOCX, PPTX, XLSX, CSV, EPUB, web pages, YouTube) and work in the web app and the iOS and Android apps. Plugins for Notion, Linear, Airtable, Canva and Microsoft 365 come with Plus.

## At every tier, here is what Chatbox AI costs versus Zemith.

Published US prices, monthly billing, checked 14 November 2026. Chatbox compute points and Zemith credits are different units and can't be compared one to one.

| Tier | Chatbox AI plan | Zemith plan | What changes on Zemith |
| --- | --- | --- | --- |
| **Free** (Try before paying) | $0: 10,000 compute points a day, 5 images, standard models, web search, Work Mode as a trial | $0: 1,100 credits a day on the free models (Qwen, GPT Luna, Gemini Flash, DeepSeek Flash), chat only | Chatbox's free tier includes web search; Zemith Free is chat only, with tools on paid plans |
| **Entry** (Light everyday use) | Lite $3.99/mo ($3.50/mo yearly): 2M points, 25 images, standard models only, no knowledge base or MCP | Plus $15.99/mo ($179.88/yr): 1.5M credits, paid models, deep research, files, Creative Studio, plugins | Chatbox Lite is cheaper to start; Plus adds research, files, video and your own keys |
| **Top models** (Claude Opus, GPT 6.1 Sol, Gemini 4 Argon) | Pro $19.99/mo ($16.70/mo yearly): 12M points, advanced models, 100 images, knowledge base, MCP | Plus $15.99/mo with your own OpenAI, Anthropic or Google key, or Pro $29.99/mo on credits | Opus on your Anthropic key from Plus; those chats use no Zemith credits |
| **Heavy use** (Long days on top models) | Pro+ $39.99/mo ($33.33/mo yearly): 30M points, 200 images | Pro $29.99/mo ($299.88/yr): 3M credits, top models on credits, Cloud tasks and schedules | Keys and credits side by side, plus Cloud agents that run while you're away |
| **Your own API key** (Pay the provider directly) | Use your own key instead of a plan: OpenAI, Anthropic, Google, OpenRouter, DeepSeek, Ollama, LM Studio and more | OpenAI, Anthropic and Google keys on Plus or Pro, one per provider, each with an on/off switch | Chatbox takes more providers and local models; Zemith keeps keys and credits in one app with tools built in |

## Our verdict: Chatbox Lite is the cheapest way in, but Zemith Plus does more for less than Chatbox Pro.

- If you only want a client for your own API key, or light chat on standard models, Chatbox's Free and $3.99 Lite plans cost less than any Zemith plan.
- Once you want Claude Opus, GPT 6.1 Sol or Gemini 4 Argon, Chatbox asks for Pro at $19.99. Zemith Plus at $15.99 reaches the same providers' top models on your own key, and keeps credits for everything else.
- Zemith adds deep research, finished Office files, video in Creative Studio and plugins, in native iOS and Android apps and on the web.

## Questions people ask about Chatbox AI pricing.

### How much does Chatbox AI cost in 2026?

On 14 November 2026 chatboxai.app listed Free ($0), Lite ($3.99 a month), Pro ($19.99 a month) and Pro+ ($39.99 a month). Billed yearly, the page shows $3.50, $16.70 and $33.33 a month.

### Is Chatbox free if I use my own API key?

Chatbox presents your own key as the alternative to a plan: its homepage says to use your own API key or subscribe to Chatbox AI for hosted models, and the desktop Community Edition is open source under GPLv3. You still pay OpenAI, Anthropic, Google or whichever provider you connect for every token.

### What are Chatbox compute points?

Compute points are Chatbox AI's unit for hosted model chats, web search and document analysis. Each model uses a different number of points per token. Lite includes 2M a month, Pro 12M and Pro+ 30M, and the quota resets on your purchase date each month without carrying over.

### Is this the Chatbox customer-support chat widget?

No. This page is about Chatbox AI from chatboxai.app, a desktop, mobile and web client for GPT, Claude, Gemini and other models. A website live-chat tool with a similar name is a different product.

### Can I use my own API key on Zemith?

Yes, on Plus ($15.99/mo) or Pro ($29.99/mo). Add an OpenAI, Anthropic or Google key under API Keys on web or in the iOS and Android apps. Chats on that provider's models are billed to your provider account and use no Zemith credits; tools such as web search and image generation still use credits.
