Leading Chat Models in the Same Conversation
No single chat model wins every category, and the only way to know which wins yours is to ask each the same question. AIGenTools makes that a one-click switch. Because GPT-5, Claude, and Gemini all live in this one AI Chat, you can put the same prompt to each and let the best answer win.
Ask, Draft, Summarize, and Refine in One Chat
Use one chat for everyday questions, long-form drafting, document summaries, brainstorming, and rewriting. It keeps the conversation context across follow-ups, so you pick up where you left off without re-pasting the background.

Attach Files and Let the Chat Reference Your Docs
Upload attachments such as PDFs, images, and documents when the answer needs your source material. The chat can reference the files you provide, which is useful for summarizing a PDF or refining writing from the same context.
Why Choose AI Chat?
Our AI Chat respects your budget, your data, and your past work, which makes it the best AI Chat for switching between GPT-5, Claude, and Gemini in one place. These essentials come with every plan, including the free one.
Free to Start, No Credit Card
Every new account gets free credits the moment you sign in — no credit card required. Free users can start using AI Chat right away; paid users get higher limits and priority. Every AIGenTools tool shares one credit wallet, and the cost is shown before each response.
Your Chat History, Always Ready
Conversations in AI Chat are saved to your account automatically — open the sidebar, search by keyword, or jump back into last week's conversation. Uploaded files stay attached to the chats they belong to, so context is easy to find.
Your Conversations Are Yours Alone
AIGenTools does not train its own models on your prompts, uploads, or outputs in AI Chat. Requests are processed by the model providers under their API data terms. Delete a conversation and it is removed with no backup, so private work stays private.
