Pi AI Review: Memory, Voice, Privacy, and Fit

10 min read · September 1, 2026

This Pi AI review has a different answer than an older review would. Pi now documents memory across chats, with a settings screen where users can see, edit, or clear remembered details. It also remains documented across Android, iOS, and the web with voice access on each. For someone who wants gentle conversational reflection without building a roleplay character, that combination is compelling.

Full disclosure: we make Nola, a competing AI emotional companion. This page is based on Pi and Inflection's own current help pages, policy, and model-training notice. It is a decision guide, not a report of personal use or a comparative performance test.

The Pi AI review verdict

Pi is best suited to gentle conversational reflection with editable cross-chat memory and broad voice access. Inflection calls it a personal AI assistant. The product now keeps selected lasting facts, gives users direct memory controls, and documents voice input and spoken output on the major consumer platforms.

Nola is the better fit when the desired job is emotional support with a next step beyond conversation. Nola remembers relevant context, notices recurring patterns, and can suggest a grounding, breathing, meditation, or sleep tool during the conversation. Pi's official materials establish a personal assistant with conversation, voice, and memory. They do not position it as a purpose-built emotional companion with that linked tool set.

Pi AI compared with Nola

This compares documented features and policies, not conversation quality, memory accuracy, or emotional outcomes.

Is Pi AI still available?

Yes, based on the current first-party record reviewed on September 1, 2026. Pi's help center has current setup instructions for Android, iOS, and web voice. Its memory page is dated July 31, 2026, and the privacy policy is dated August 11, 2026. Those pages describe a live consumer service rather than a historical product.

That is the careful version of an availability claim. We are not inferring store ranking, download volume, regional access, or future availability. A product can change quickly, so confirm the relevant app or web access in your location before depending on it.

Pi AI memory is new, visible, and editable

Pi says its memory focuses on information that remains useful for future conversations: names, family details, food preferences, hobbies, work or study, communication preferences, and ongoing goals or habits. It is designed to skip temporary plans and one-off events.

There are two ways to control it. In conversation, a user can ask Pi to remember a fact or forget one. In Settings, under Account and Manage Memories, the user can add, delete, or update the saved items directly. That visibility matters. Memory is easier to trust when you can inspect the short list the product intends to carry forward.

The documentation also gives a useful limitation: a user may have to repeat an instruction to make a memory stick. Nothing in the official sources supports perfect or complete recall. The right conclusion is that Pi has configurable continuity, not that it remembers everything. Our guide to AI companions with memory compares this approach with other documented memory systems.

Where Pi's memory beats Nola

Pi beats Nola on documented user-facing memory controls. Its help page names a Manage Memories screen and lets users add, update, and delete specific remembered details. Nola supports relevant cross-conversation context, but the approved Nola evidence does not document an equivalent memory editor.

Nola's advantage is what she is designed to do with relevant context. She can notice the third replay of the same disagreement, ask a reflective question about the pattern, and connect the conversation to an appropriate in-app tool. If direct inspection and editing of memory is your first criterion, Pi has the clearer official feature. If pattern recognition within an emotional-support flow is the priority, Nola has the stronger product fit.

Pi AI voice and conversational access

Pi documents voice on Android, iOS, and web. Mobile users grant microphone and speech permissions; web users turn Voice On and confirm the correct microphone and speakers. The help page describes both speaking to Pi and hearing Pi's responses, so this is broader than dictation alone.

Pi also beats Nola on documented spoken access. Nola's supported feature is voice input through a microphone control. The current evidence does not establish two-way spoken conversation. If you want to talk while walking or hear replies rather than read them, Pi's first-party documentation is clearer and broader.

What it does not establish is commercial entitlement. The voice instructions do not say whether voice belongs to a current free plan, a paid plan, or a usage allowance. Access instructions and pricing evidence are different things, and this review does not blend them.

Pi AI pricing: no verified current terms

The reviewed first-party sources do not publish a current Pi free plan, paid plan, subscription entitlement, or dollar price. That may feel surprising because Pi is easy to encounter as a consumer product, but a decision page should not turn product availability into a price claim.

We therefore do not state that Pi is free, do not invent a subscription amount, and do not infer that every documented voice or memory feature has no limit. Check the live interface and any checkout shown to your account. If cost is your main filter, use our guide to confirmed free AI emotional-support starting points.

Pi AI privacy and model-training controls

Pi's August 2026 privacy policy says inputs can include text, voice, audio, and other materials. It says information is used to provide, maintain, and improve the services, including developing and training the models that power them. Users can opt out of model training in Account settings.

The policy also says Pi may use inputs to infer emotional state, tone, sentiment, or other characteristics. A separate account setting lets users opt out of using voice to infer emotions. Those are meaningful controls, but the default collection and use still deserve attention before sharing sensitive material.

Inflection says it does not engage in sales or sharing of personal information or targeted advertising as those terms are defined by US state privacy laws. It lists service providers for hosting, cloud storage, security, content moderation, marketing, measurement, and support, along with disclosures for legal process and corporate transactions. These are company policy statements, not guarantees that Pi is completely private or secure.

For a field-by-field way to review these terms, use our AI companion privacy checklist. Training choice, derived emotion data, message deletion, retention, and third-party processing are separate questions.

Deletion and retention need a careful read

Pi's current privacy policy says users can delete individual messages, which are removed immediately from conversation history. Users can also delete their information through the Account page or by typing !delete in chat. This newer dated policy supersedes an older help answer that said partial deletion was unavailable.

Deletion from the visible history is not the whole retention story. Pi says deleted inputs are generally retained for no more than 15 days, with longer exceptions for fraud, abuse, security, legal requirements, and financial records. It also says outputs are retained indefinitely for limited purposes described in its terms.

That indefinite output statement is the sharpest privacy drawback in the reviewed evidence. An output can reproduce personal information supplied in an input, and the policy itself warns that this can happen. A reader deciding whether to share something highly identifying should consider both the control and the retention language, not just the delete button.

Category limits: Pi is a personal assistant

Inflection describes Pi as a personal AI assistant and chatbot. That category can still support a warm, reflective conversation. It does not mean Pi is incapable of discussing a difficult day. It does mean the reviewed product pages do not establish Nola's narrower design around emotional patterns and linked support tools.

Likewise, Pi is not presented in these sources as a configurable roleplay relationship. If that is what you want, a product such as Nomi or Replika belongs in a different comparison. Our Nola vs Replika guide explains that choice, while Nola vs ChatGPT covers the general-assistant side. Claude belongs in that broad general-assistant category too. Supportive conversation can still be one use of a general assistant.

Who should choose Nola instead

Choose Nola if you want a conversation-first emotional companion that can remember relevant context, notice repeating patterns, ask a useful question, and move into an appropriate tool without making you search a content library. The supported tool set includes grounding, box breathing, physiological sighs, human-recorded meditations, sleep stories, soundscapes, night content, and a timer.

Choose Pi if voice across devices and an editable memory list are more important than that purpose-built emotional flow. Pi's gentle assistant style, current cross-chat memory, and broad spoken access are real strengths. Nola is the clearer choice for the 2 a.m. spiral where words may need to turn into a calming or sleep action.

Nola is free to start, with some tools and unlimited conversations on a paid plan. Nola does not sell conversations or personal information. Nola does not use personal conversations to train generative AI models. Trusted AI infrastructure providers may process text and context to generate replies, and limited authorized human access may occur under the reasons listed in the privacy policy. These are policy statements, not guarantees. See the safety page for clear product boundaries.
