Complete guide to Pi AI
Getting started
Go to pi.ai (or download the app on iOS/Android) and start talking to Pi as if it were a normal conversation, by text or by voice. There's no special setup needed: Pi remembers the context of previous conversations and builds up different conversation threads represented as cards in your panel, each with its own topic.
Use cases
Personal reflection and journaling
Using Pi as a conversation space to process the day's thoughts, without looking for a productive or technical answer.
Support for everyday decision-making
Thinking out loud about a personal decision with a conversation partner that asks follow-up questions instead of just giving a direct answer.
Daily check-ins
Having a short, recurring conversation about how the day is going, taking advantage of Pi remembering the context from previous sessions.
Natural voice conversation
Talking with Pi using one of its six distinct voices, for an interaction that feels more like a phone call than a text chat.
Advanced setup
- Conversation cardsEach distinct topic or conversation thread is represented as a separate card in the panel, making it easy to pick a specific topic back up later.
- Real-time web searchPi can search for current information on the web within the conversation itself when the question calls for it.
- Voice selectionYou can choose from six distinct voices for spoken conversations, each with its own personality.
Tips
- Don't expect Pi to be the best option for coding, research, or analyzing documents — it's designed for empathetic conversation, not technical productivity; use Claude or ChatGPT for that.
- Take advantage of conversation cards to keep topics separate (work, personal, decisions) instead of mixing everything into one long thread.
- Try voice mode for conversations you'd normally have while walking or driving, instead of typing.
- It's completely free with no usage limits, so there's no reason to ration conversations for fear of a cost.

Who develops it?
Inflection AI, running on its own Inflection 2.5 model, with performance comparable to GPT-4 but focused on an empathetic conversational style.
Is it good for work tasks like coding or research?
That's not its strong suit — it's designed for reflective, companionship-style conversation, not technical or productivity tasks.
