Frequently asked questions
1Is Pi free to use, or is there a subscription model?⌄
Pi is currently offered as a free-to-use service directly through its web interface and mobile applications. Inflection AI has not announced any premium subscription tiers or paid features at this time, focusing on broad accessibility.
2What are the primary limitations of Pi compared to other large language models (LLMs)?⌄
Pi is optimized for personal, supportive conversation rather than factual recall or complex task execution. Its primary limitation is a less extensive knowledge base for highly specialized or real-time factual queries compared to models designed for search augmentation or detailed data analysis. It also lacks direct API access for integration into other applications.

Yes, Pi is designed with a persistent conversational memory. It can recall context and details from your past interactions, allowing for more personalized and continuous dialogue over time, provided you are logged in. This memory helps maintain a consistent conversational thread.
4Is there a mobile application for Pi, or is it strictly browser-based?⌄
While Pi emphasizes a browser-first experience for web discoverability, it also offers dedicated mobile applications for both iOS and Android devices. These apps provide a similar conversational interface, ensuring a consistent user experience across platforms.
5How does Pi handle user data and privacy?⌄
Inflection AI states that user conversations are used to improve the model, but they emphasize privacy. Users typically have options to delete chat history. Specific details on data retention, anonymization, and security protocols are outlined in their privacy policy, which is accessible from the website.
