What is an all-in-one AI chat?

An all-in-one AI chat gives you many AI models from different companies in one app and one account. Instead of paying for ChatGPT, Claude and Gemini separately, you pick the best model for each question, compare their answers side by side, and pay only for the messages you send.

The cost math

Three subscriptions come to about $59.99 a month. On NanoGPT you pay per message, so the bill follows how much you use and which model you pick. Here is the same month on GPT 6 Astra, Claude Opus 5.5 and Gemini 4 Argon, the top models from those three companies.

Three separate subscriptions

  • ChatGPT Plus$20.00/mo
  • Claude Pro$20.00/mo
  • Google AI Pro (Gemini)$19.99/mo

Total$59.99/mo

One NanoGPT balance

  • 10 messages a day, mixed$7.20/mo
  • 30 a day, all on Qwen3.8 Max$5.94/mo

30 a day across all three$21.60/mo

Subscription prices are the US monthly list prices on October 31, 2026. NanoGPT estimates use today’s prices, with “mixed” messages split evenly across GPT 6 Astra, Claude Opus 5.5 and Gemini 4 Argon,each sending about 1,500 tokens and receiving the model’s average reply on NanoGPT (or 600 tokens). Long chats, files and reasoning cost more; short questions cost less.

AI model comparison: which model for which job

The #1 model on NanoGPT for each job; each card says which ranking it comes from. These change when a better model ships.

Ask several models at once

Send one message to up to four models and read the replies next to each other. Keep going with the answer you like best. A single-company subscription can’t do this.

Frequently asked questions

Is NanoGPT a real ChatGPT alternative?

Yes. It’s a chat app in your browser, like ChatGPT, but with about 1,000 models to choose from, including OpenAI’s GPT models, Claude, Gemini, Grok, DeepSeek and open models. You can switch models in the middle of a conversation.

Is it the same GPT model as in ChatGPT?

Yes. GPT models on NanoGPT are the same models developers use through OpenAI’s API. The model you pick is the model that answers; NanoGPT doesn’t quietly swap in a cheaper one.

How does pay per prompt work?

You add a balance (from $0.10 in crypto, or by card from $1 the first time and $5 after that) and each message costs what its tokens cost on that model. Text models are billed at list prices with no markup, and your usage page shows what each model cost you. See pricing.

Can I use Claude without a Claude subscription?

Yes. Claude models are available in the same chat and pay-as-you-go balance as every other model, with no Anthropic account or subscription. That makes NanoGPT a Claude alternative that still includes Claude.

Is there a free tier?

You can try a free model without signing up or adding money. Paid models need a balance. The optional Pro plan is $12 a month for 60M input tokens a week on open models and 100 images a day.

Is my data used for training?

NanoGPT doesn’t train on your chats and doesn’t log your prompts or replies. Your chat history is stored on your device. The model provider receives your prompt to answer it; turn on Zero Data Retention routing in Settings to use only providers that say they keep no copy. How private chat works.
