Frequently Asked Questions

How do you pronounce NitoAI? What's the origin of the name?

It's pronounced as 'Nito-AI'! The name comes from a Japanese proverb '二兎を追って二兎を得る' (pursuing two hares and catching both), representing our ability to ask multiple AIs at once.

Why can you offer the service at such an affordable price?

AI services like ChatGPT offer pay-as-you-go contracts separate from their subscriptions. Behind NitoAI, we have pay-as-you-go contracts with various AI providers, allowing us to provide the same functionality to our customers at a lower cost.

About team features and corporate contracts

Team features allow you to consolidate payments for multiple users by creating a team from the settings screen. Also, even if you are a corporate user, you can use the service with a regular registration if you are fine with individual contracts.

Can I use it for free? Do I need to register a credit card?

Yes, you can use it for free. No payment information is required for registration.Free plan limitations include 30 text chats per month and a prompt length limit of 2,000 characters per message.

I want to send long messages but can't

Free accounts are limited to 2,000 characters per prompt. With a paid subscription, you can send up to 20,000 characters per prompt.

What features are planned for development?

We plan to release the following features as they are developed: ・File upload and PDF content analysis ・Web information search and answers (adding Perplexity) ・Image generation with DALL-E (consuming 5 text generation credits per image) ・Search through past conversations ・AI comparison and summarization of different AI responses ・PC and mobile app versions ・Import chat history from existing AI chat services

Is my input used for training? Can others see my conversations?

Content sent through NitoAI is not used for training. Also, conversations cannot be viewed by others unless they are set to public. However, for models marked as 'No opt-out' in the model list, the content may be used for training. In the team plan, we plan to provide a feature that allows administrators to disable models with no opt-out option.
