Notto AI

Notto AI is a chat platform that puts 16 AI models behind one interface, so you can move between GPT-5.4, Claude, Gemini and others without opening separate subscriptions. Beyond chat, it includes built-in web search for questions that need current information, file upload analysis for images, PDFs and documents, and automatic saving of chat history with search, so you can pick up an earlier conversation. A comparison feature lets you send the same prompt to different models and read the answers side by side, which is useful when you want to see how each one handles tone, structure or reasoning. If you prefer to pay the underlying provider directly, you can bring your own API key; the page states keys are encrypted with AES 256 rather than stored in plain text. New accounts receive 500 free credits, and the paid plan is listed at $99.90 per month with 100,000 credits.

- Switch models inside one conversation when an answer is not working.

- Ask questions that need live web results without leaving the chat.

- Upload a PDF, image or document and have any model analyse it.

- Compare several models on the same prompt before settling on one.

- People who use AI daily and want one place for several models.

- Developers testing prompts and behaviour across models.

- Content creators who want different tones for the same draft.

The free allowance is 500 credits, which goes quickly if you use file analysis or long conversations, and the jump to the paid tier is a large step at $99.90 per month, so check how your own usage converts into credits before committing. Bringing your own key means you are still billed by the model provider and bound by their terms. The platform sits between you and those providers, so read its data handling policy before uploading anything confidential. The credit rules and the model list can change, and nothing here guarantees that a given model stays available.
