Chat with multiple AI models in one interface

NetusAI Chat is a multi AI chat app that puts 41 models from OpenAI, Anthropic, Google, and xAI in one interface, on one credit balance that starts free. Pick the model per task instead of per subscription: a nano model for quick questions, a frontier model when the answer matters.

A NetusAI chat thread where the reply model changes from GPT-5 Mini to Claude Sonnet 5 without restarting

No restarts

Switch models mid-conversation, keep the context

Change the model between any two messages and the full conversation goes with you. Draft an outline with GPT-5 Mini, hand the hard reasoning to Claude Opus 4.8, and let Gemini 2.5 Flash summarize the thread, all in the same chat.

Per-message choice. The model selector sits right in the chat box, with each model's credit rate next to its name.

A default that fits you. Set a default model for new chats, and change it any time in settings.

Search across everything. Find any chat or project by title, whatever model wrote it.

Pricing

Multiple AI models in one subscription

One plan replaces the stack of single-provider subscriptions, and you pay per token at a rate shown before you send. Every paid plan unlocks all 41 models; plans differ only in credits, web searches, and storage.

See the full plan comparison

Each model has a published rate per 1,000 tokens, and you spend credits only on the tokens you actually use, so a question sent to a cheap model costs a fraction of one sent to a frontier model. A sample of the rates in the picker:

Model Credits per 1k tokens
GPT-5 Nano 0.05
Gemini 2.5 Flash Lite 0.06
GPT-4o Mini 0.1
Grok 4.3 0.25
GPT-5 Mini 0.25
GPT-5 1
Gemini 2.5 Pro 1
Claude Sonnet 5 1.2
Claude Opus 4.8 3
Claude Fable 5 6.75

On Starter's 500 credits, that is up to 2 million tokens of GPT-5 Mini a month.

Run out mid-month? Top-up bundles ($4 for 200 credits up to $39 for 2,500) never expire, even if you cancel.

How far do your credits go?

Every model has a different credit rate. Set your usage once and see what each plan really buys.

Message size Words vs tokens
AI models measure text in tokens, not words.
A rough rule: 3 words ≈ 4 tokens (about 750 words = 1,000 tokens).

Beyond the model

Web search and extended thinking on every paid plan

Web search

Give any model live web results with sources. Every paid plan includes a monthly quota of free searches (10 on Starter up to 125 on Max); after that, a search costs 15 credits. Not available on the Free plan.

Extended thinking

Turn deeper reasoning on per message for models that support it, and pick the effort level (low, medium, or high) to trade speed against depth. Also a paid-plan feature.

Context that persists

Files, projects, and knowledge sources

File chat

Upload PDFs, Word documents, spreadsheets, presentations, images, and code files into any conversation and ask questions against them. Size limits vary by the model's provider (30 to 100 MB per file).

PDF DOCX XLSX PPTX Images Code

Projects

Group chats around one piece of work, with custom instructions the AI follows in every chat inside the project.

Knowledge sources

Attach reference files (up to 500 MB each) or pasted text to a project once; every model working in that project can draw on them. Free plan includes 2 projects; paid plans have no limit.

Connectors

Connect Notion, GitHub, and 5 more tools

Let the assistant search and read from the tools you already use, directly in chat. Nine connectors are live today: Notion, GitHub, Linear, Asana, monday.com, Airtable, and Stripe.

Each connector's permissions are controlled per tool: always allow, needs approval, or off.

Privacy

Your chats stay yours

Model training on your data is turned off with every provider we route to. Your conversations live in your private workspace, and nobody else can read them. Providers retain API data briefly for abuse monitoring per their published policies (OpenAI, Anthropic, Google, xAI), then it is deleted. Delete your account and your data goes with it, immediately.

For teams

Built for teams too

The same 41 models work in a shared organization: one pooled credit balance, shared projects and knowledge sources, roles, and per-member usage stats, from $7 per seat per month. AI workspace for teams is where we cover it in depth.

Multi AI chat FAQ

A multi AI chat (also called an AI aggregator or LLM aggregator) is one app that puts multiple AI models in one place, so you use GPT, Claude, Gemini, and Grok through a single interface and a single subscription instead of separate accounts. Every multi AI chat pays the model providers for each message you send, so no service can offer truly unlimited use of top models. If a site says "unlimited", look for the hidden caps. NetusAI Chat publishes each model’s credit price in the picker instead, so you see the cost before you send.

41 models across four providers as of July 2026: 24 from OpenAI (including GPT-5.6 Sol and the GPT-5 line), 9 from Anthropic (Claude Fable 5 through Haiku 4.5), 7 from Google (Gemini 3.5 Flash to 2.5 Flash Lite), and Grok 4.3 from xAI. New models are added as providers release them.

Yes. The Free plan includes 50 credits a month, 6 models (GPT-5 Mini, GPT-5 Nano, GPT-5.4 Nano, GPT-4o Mini, Gemini 2.5 Flash, and Gemini 2.5 Flash Lite), 2 projects, and 200 MB of storage. No card required. Web search and extended thinking need a paid plan.

Every plan includes monthly credits, and every model shows a rate per 1,000 tokens: 0.05 credits for GPT-5 Nano, 1.2 for Claude Sonnet 5, 3 for Claude Opus 4.8. You are charged only for the tokens you use, and the rate sits next to each model in the picker, so the cost of a message is never a surprise.

Yes. Pick a different model from the picker at any point and the full conversation context carries over. Nothing restarts and no history is lost.

If you only ever use OpenAI models, ChatGPT is fine. NetusAI Chat is the better fit when you want Claude, Gemini, or Grok in the same place: an all-in-one AI chat where one $7 subscription covers all 41 models instead of one provider’s. The free plan even works as a free ChatGPT alternative for light use, with 50 credits a month on 6 models.

No site offers every frontier model free without limits, because providers charge for every message behind the scenes. NetusAI Chat’s free plan gives you 50 credits a month across 6 fast models, no card required. The other 35, including Claude Opus 4.8 and GPT-5.6, unlock on any paid plan from $7 a month.

No. Training on your data is disabled with every provider NetusAI routes to, and conversations stay private to your workspace. Providers hold API data briefly under their published retention policies, then delete it.

Documents (PDF, DOCX, TXT, CSV, XLSX, PPTX, HTML, Markdown, JSON), images (JPEG, PNG, GIF, WebP), and code files. Per-file size limits depend on the model’s provider, from 30 MB up to 100 MB. Project knowledge sources take files up to 500 MB each.

Yes. Organizations get a shared credit pool, shared projects and knowledge sources, member roles, and per-member usage stats, priced per seat from $7 a month. A dedicated teams page is coming; until then, create an organization from the account switcher in the app.

Every model. One credit balance.
