AI Chatbot — every model, one chat
Chat with GPT, Claude, and Gemini from one window on a single subscription. Switch models mid-conversation, search the live web, upload files, and build team knowledge bases — all billed from one pool of credits.
No credit card needed
A serious chat tool, not just a model switcher
Web search, reasoning control, file uploads, project knowledge bases, and team workspaces — wired into every model and billed from one credit pool.
Every model, one chat
Chat with GPT, Claude, and Gemini side by side and switch models in the middle of a conversation without losing context. Pick the right model for each message.
Live web search
Turn on search and the model answers from the live internet with real sources instead of a stale training cutoff. Powered by real-time web search and page fetch.
Reasoning control
Flip on thinking for models that support it and dial the effort Low, Medium, or High. Watch the reasoning stream and pay only for the tokens it uses.
Chat with your files
Drop in PDFs, DOCX, spreadsheets, slides, code, and images up to 50MB and the model reads them inline. Ask questions, summarize, or extract data instantly.
Project knowledge bases
Group chats into a project, attach your documents, and every reply is grounded in your own knowledge through retrieval. Add custom instructions per project.
Built for teams
Spin up an organization, invite your team, and share projects and chats. Everyone draws from one shared credit pool, with per-member and per-model usage analytics.
Switch models mid-conversation
Start on a fast, cheap model, escalate to a frontier reasoning model for the hard part, then drop back to a lightweight one to wrap up — all in the same thread, with full context carried across.
The chatbot routes each message to the right provider automatically from the model you pick, so you never manage API keys or juggle separate apps. One prompt costs the same no matter who serves it.
Project knowledge base
Chat grounded in your own documents
Group related chats into a project and attach a knowledge base of PDFs, docs, spreadsheets, and notes. Every answer inside that project is grounded in your own content through retrieval, with custom instructions that set the tone and rules.
Need a one-off? Drop any file straight into a chat — up to 50MB — and the model reads it inline. Perfect for contracts, research papers, datasets, and codebases.
Search the web and control the reasoning
Toggle web search and the model answers from the live internet with real sources, not a stale training cutoff. Toggle thinking and dial the effort Low, Medium, or High for models that support it — watch the reasoning stream and pay only for the tokens it uses.
Every paid plan includes a monthly free-search quota, and searches beyond it are just 15 credits each.
38 models, priced in plain credits
Every model runs on the same credit currency, so a prompt costs the same no matter which provider serves it. Reasoning tokens are already included in the rate shown.

One chatbot for every kind of work
From developers and researchers to content teams and students — anyone who wants the best AI models without the busywork of managing four separate subscriptions.
Developers & engineers
Compare model answers on the same coding problem, paste in stack traces and files, and escalate to a reasoning model only when a task is hard enough to need it.
Researchers & analysts
Upload reports and datasets, ground answers in a project knowledge base, and pull in live web results to fact-check with citations.
Content & marketing teams
Draft, rewrite, and brainstorm in a shared workspace where the whole team pulls from one credit pool and you can see exactly where spend goes.
Founders & solo builders
One subscription instead of four. Get frontier models, web search, and file chat on a free plan and only pay when you outgrow it.
Students & learners
Turn lecture notes and PDFs into study help, get step-by-step explanations, and start free with 50 credits and six models every month.
Support & operations

AI Chatbot FAQs
What is the NetusAI AI Chatbot?
It is a unified AI chat app that lets you use every major AI model — from OpenAI, Anthropic, and Google — in one interface, on one subscription. Instead of paying for and switching between separate ChatGPT, Claude, and Gemini apps, you chat with all of them from a single window and pay in one shared pool of credits.
Which AI models can I use?
You get access to the full frontier lineup across three providers, including GPT-5 and GPT-4.1 models from OpenAI, Claude Opus, Sonnet, and Haiku from Anthropic, and Gemini Pro and Flash models from Google. New models are added as the labs ship them.
Can I switch models in the middle of a conversation?
Yes. You can change the model on any message and keep the same thread and context. Start on a fast, cheap model, escalate to a reasoning model for the hard part, then switch back — all in one chat.
Is there a free plan?
Yes. The free plan gives you 50 credits every month and access to six models, with no credit card required. It is enough to do real work before you decide to upgrade.
How do credits work?
Everything is billed in one transparent currency where 1 credit equals $0.001. You are charged on total tokens processed — input plus output — at each model’s rate, so the same prompt costs the same no matter which provider serves it. Reasoning tokens are already included in the rate shown.
Does it support web search?
Yes. Toggle web search on and the model answers using live results from the internet plus full-page fetch, with sources. Web search costs 15 credits per search, and every paid plan includes a monthly free-search quota.
Can I upload files and chat with my documents?
You can upload PDFs, DOCX, spreadsheets, slides, images, and code files directly into chat, up to 50MB. For ongoing work, create a project, attach a knowledge base, and every answer in that project is grounded in your documents through retrieval.
Can my whole team use it together?
Yes. Create an organization, invite 2 to 1000 members, and share projects and chats. The whole team draws from one shared pool of credits, and owners and admins get per-member and per-model usage analytics. If you run low, top-up credit bundles are available any time and never expire.
Is my data private?
Your personal account is a private workspace that is not shared with anyone. In organizations, chats are private by default and only become visible to other members when you explicitly share them.
What is a credit?
A credit is the unit used to measure usage on our platform. It is used to access different NetusAI tools and features. Different tools consume credits at different rates depending on the task. For example, humanizing or paraphrasing text costs 1 credit per 10 words, while a readability check consumes 1 credit per analysis. Each plan comes with a set number of credits per month, and your credits reset at the start of every billing cycle.
Stop paying four AI bills
Bring every frontier model into one chat, one workspace, and one credit balance. Free to start — no card required.
