What is Pi AI?
Pi is a personal AI assistant by Inflection AI, designed to be empathetic, conversational, and emotionally intelligent. Unlike ChatGPT and Claude which focus on tasks, Pi is built for genuine conversation, it remembers your preferences, asks follow-up questions, and adapts its tone. Free to use with no subscription required. Pi excels at open-ended conversation, helping users think through personal decisions, offering emotional support, and providing a friendly AI companion experience. It is available on iOS, Android, and web at pi.ai. Pi stands out for its warm, natural conversational style that feels less like talking to a machine and more like chatting with a thoughtful friend. While it lacks the raw analytical power of the frontier models behind ChatGPT or Claude, Pi fills a unique niche as an AI that prioritizes emotional connection over task completion. Inflection AI, a public benefit corporation now led by CEO Sean White, describes Pi as a personal intelligence partner running on its own stack of fine-tuned models. There is no model picker: Pi runs on Inflection AI's own model and the help centre says no other option is available. Both mobile apps were still shipping updates in the first week of September 2026.
Pi AI Pricing
Completely free. No paid tier, no subscription, and no in-app purchases: Apple's App Store and Google Play both list the app at $0 with nothing to buy inside it, and Inflection AI's terms of service contain no fee or billing terms.
The thing Inflection does not publish is a usage limit. In August 2024 it said it would begin capping message volume for free users, and it has never said where that cap sits, so treat any claim that Pi gives you unlimited messages with caution. Accounts are also 18+ only.

FAQ
What is Pi AI?
Pi is a personal AI assistant created by Inflection AI. It is designed to be empathetic, conversational, and emotionally intelligent. Unlike task-focused AI assistants like ChatGPT, Pi prioritizes genuine conversation, remembering your preferences and adapting its tone to create a more personal interaction.
Is Pi AI free?
Yes. Pi has no paid tier: Apple's App Store and Google Play both list the app at $0 with no in-app purchases, and Inflection AI's terms of service contain no fee or billing terms. What Inflection does not publish is a usage limit. In August 2024 the company said it would begin capping message volume for free users, and it has never said where that cap sits, so treat any claim that Pi gives you unlimited messages with caution.
Who made Pi AI?
Pi is made by Inflection AI, Inc., a public benefit corporation based in Palo Alto, California. It was co-founded by Mustafa Suleyman (a co-founder of DeepMind), Karén Simonyan, and Reid Hoffman. Leadership has changed since then: Inflection's own July 2026 announcement names Sean White as CEO. The company describes Pi today as a personal intelligence partner powered by its own stack of fine-tuned models.
How does Pi AI compare to ChatGPT?
Pi and ChatGPT serve different purposes. ChatGPT excels at complex tasks like coding, analysis, image generation, and web browsing. Pi excels at empathetic conversation, emotional support, and being a thoughtful companion. ChatGPT is more powerful; Pi is more personal. Many users find Pi better for casual conversation and thinking through personal decisions, while ChatGPT is better for work tasks.
Is Pi AI safe to use?
Yes. Inflection AI has built Pi with safety as a core design principle. Pi avoids generating harmful content, refuses inappropriate requests, and is designed to be supportive rather than manipulative. As with any AI, avoid sharing sensitive personal information like passwords or financial details.
Does Pi AI remember conversations?
Yes. Pi remembers things that stay true about you across chats, such as your name, your city, food preferences and allergies, your job, and ongoing goals, and uses them to personalize later conversations. You can see, add, and delete those memories yourself under Settings, then Account, then Manage Memories, or just tell Pi in chat to forget something.
Can Pi AI browse the internet?
No. Pi does not have web browsing capabilities. It cannot search the internet in real-time or access current news and events. For research tasks requiring up-to-date information, consider Perplexity AI or ChatGPT with browsing enabled.
Can Pi AI generate or upload images?
No. Inflection AI's help centre states plainly that Pi does not support generating, uploading, or editing images. There is also no way to pick or switch the model behind Pi: the help centre says Pi runs on Inflection AI's own model and that no other option is available.
What devices is Pi AI available on?
Pi is available on the web at pi.ai, as well as native apps for iOS and Android. It also supports voice chat, so you can have spoken conversations with Pi on your phone. The experience is consistent across all platforms.
