About All AI Models in One: Ask AI
Fast AI puts AI models from several companies in one chat on your iPhone. Pick a model, ask anything, and switch whenever you like, in the same conversation.
WHAT YOU CAN DO
• Ask questions and get clear answers
• Write, rewrite, summarize and translate
• Study a topic or get unstuck on homework
• Search the web automatically for current questions (Pro)
• Have any answer read aloud
• Chats get automatic titles, so they are easy to find later
QUESTIONS
Is Fast AI free?
You can send a few messages every day for free. Pro (weekly or yearly, auto-renewing) unlocks every model, web search and a much higher daily limit. Prices are shown in the app before you buy.
Can I switch models in the middle of a chat?
Yes. Change the model at any time and keep the same conversation.
Which models are included?
Models from several companies, such as Gemini, Claude, Grok, DeepSeek and Perplexity Sonar. We update the list as new models come out.
Does it know about current events?
With Pro, Fast AI searches the web by itself when your question needs fresh information.
Does it make images or read files?
No. Fast AI is chat only: no images, videos or files.
Fast AI is made by Saga Labs, an independent studio. It is not affiliated with the companies whose models it uses; their names belong to their owners.
Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel it in Settings > your name > Subscriptions.
