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.

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.

How to use the NetusAI chatbot

Getting started takes seconds. No setup, no API keys, no credit card.

01

Create your free account and open a new chat. You start with 50 credits and six models — no card required.

02

Pick a model from the selector, then toggle web search or thinking and attach files if you need them. Switch models any time without losing the thread.

03

Chat away. Group related chats into a project with its own knowledge base, or invite your team to share one credit pool.

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

Build a project around your internal docs so answers stay grounded in your policies, and share the chats read-only across the org.

Pricing

Start free, then scale by the seat. Every paid plan unlocks the full model lineup, web search, thinking, and unlimited projects.

AI Chatbot FAQs

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.
