Quest personal AI advisor: memory that knows you

Key facts

What is Quest and who launched it?

Quest is a personal AI advisor you talk to as “Q.” New Quest AI Inc., a Delaware company based in San Francisco, makes it (Quest privacy policy). Founder Vincent Nallatamby launched Quest on 5 November 2026; Launch Archive preserved the X launch post, and Les Echos covered the same day at 18:00, naming cofounder Thomas Girardier and describing both as French entrepreneurs formerly at Google.

Les Echos quotes Nallatamby: people will have several AI agents, and Quest is the mentor that knows the user by heart (Les Echos). The product site frames Quest as your most personal AI: it studies you to write Your Memory, design Your Relationship Map and craft Customizable Mini-Apps, with its Own Phone, Proactive Advisor role and the ability to Manage AI Assistants (new.quest).

How do you talk to Quest and what does it connect to?

iMessage, text and voice

The App Store listing describes Quest as a personal AI advisor: you talk to Q. like anyone else, in iMessage, through text or voice messages. Quests can be big or small — learn to surf, finish a half marathon, or remember the trash — and Quest makes a plan, tracks progress and checks in as much or as little as you like. It can message you proactively when something happens, such as visiting a new place or finishing a workout.

Apps you choose

Quest connects to apps only after you opt in. The privacy policy lists email and calendar (Gmail, Google Calendar, Google Drive, IMAP), health (Apple Health, Oura, Hevy), meetings and notes, tasks and work tools, money apps, media and social, messaging on Quest’s phone, Muse and Instinct, websites via Quest’s browser, and one-time imports such as YouTube history (privacy policy). Location and Apple Health are off by default.

Own phone and other assistants

Messaging apps such as WhatsApp, Messenger, Instagram and TikTok run on Quest’s own phone. Quest can also supervise Muse and Instinct on that phone: Muse through its app, Instinct through your WhatsApp account (privacy policy). That “manage AI assistants” pitch is part of the product homepage (new.quest).

What do Memory, Relationship Map and mini-apps mean in practice?

When you connect an app, Quest reads available data — including history — and builds facts, anecdotes and hypotheses about your personality and goals into Your Memory. It also learns about people you interact with from email, calendar and chats you share (privacy policy). The Relationship Map and Customizable Mini-Apps are called out on the homepage as core surfaces (new.quest).

The founder launch post, as checked by The Independent AI, used strong marketing lines such as studying you like a profiler, radical transparency and “100+ wiki files.” Independent AI rated the overall pitch “partly fact”: personal-agent functions and policy controls are documented, while implied dependable life guidance from promotional examples is not established. We treat those launch claims as marketing, and rely on the App Store, site and privacy policy for product facts.

How does Quest handle privacy and approvals?

The privacy policy (last updated 3 November 2026) is unusually specific: opt-in per app, no selling data, no ads, no training AI models on your data, and never purchasing or signing up without permission (privacy policy). For messaging, Quest sends only in chats you choose; it can manage a conversation within your instructions but still asks before sharing anything confidential or sensitive about you.

Disconnecting an app stops new reads; learned Memory may remain unless you ask Quest to correct or delete facts. Terms reviewed by Independent AI state that AI output may be inaccurate and is not a substitute for medical, legal, financial or mental-health advice (Independent AI). That approval-first habit fits our health routine coach and habit check-ins patterns — with you still deciding anything sensitive.

How much does Quest cost and who can use it?

The App Store lists Quest as Free, designed for iPhone, iPad and iMessage, requiring iOS 18.0 or later (iPadOS 18+, with Mac and Vision compatibility notes on the listing). The developer is New Quest AI Inc. (App Store).

Paid subscription pricing beyond the free download is unknown. Independent AI also marks cost beyond download as not verified in its 5 November 2026 check (Independent AI). We do not invent prices on the Quest profile.

How does Quest compare with Meta Muse and Instinct?

Meta Muse is Meta’s personal agent you can message on WhatsApp and its own apps, with a free tier and paid plans. Instinct is a highly funded, invite-only personal agent you text or call. Quest sits in the same personal-agent category, with an iMessage-first advisor pitch, deep Memory/Relationship Map marketing, its own phone for social apps, and an explicit ability to supervise Muse and Instinct (new.quest; privacy policy).

What should you watch next with Quest?

Watch whether a paid plan is published, how Memory controls evolve when you disconnect apps, and how the Muse/Instinct supervision feature behaves as those products change (privacy policy; Independent AI). Also watch App Store regional availability beyond the US listing we checked.
