Evie - Offline Family AI

Safe, private voice learning

Free · In‑App Purchases

Read aloud is now one tap under every reply, and follows along sentence by sentence. Fully offline — no sign-up, no cloud, nothing your family says leaves the device. Private AI for families, on-device, free to try. Evie is an AI voice assistant for families, built around a single idea: your child's conversations never leave the device. Speech recognition, the language model, and the neural voice all run on the Apple Neural Engine. No sign-up, no cloud, no analytics, no data sharing. After a one-time model download, Evie works offline forever. NATURAL VOICE CHAT Push to talk and hear a reply that streams sentence-by-sentence, so the voice starts almost instantly. Type instead in quiet rooms — same model, no audio. Replay any answer aloud. AUDIENCE-AWARE PERSONA • Little (Under 5): tiny words, very short replies, slowest pace. • Kid (5–10): short answers, gentle tone, warm vocabulary. • Teen (11–17): more depth, still safe and curious. • Adult: persona-neutral, no length cap. Tone, reply length, and speaking pace are tunable per audience; parents can add extra instructions (Pro). LEARNING MODES • Socratic — answers with guiding questions. • Storyteller — listen, or co-create together (Pro). • Curious Scientist (Pro) — mechanism-first explanations full of wonder. • Calm Bedtime — quiet, slow-paced, winding-down replies. LESSONS A program that teaches how to think, not just facts, across four tracks: Independent Thinking, AI Cognition, Emotion & Responsibility, and Online Life. Each lesson blends reviewed, authored steps with a friendly "say it your way" moment, plus a companion guide for parents. The first lesson in every track is free; the rest unlock with Pro. PARENT MODE Controls sit behind a simple math challenge so kids can't change their own settings. Set daily allowed hours and weekdays, and whether kids can clear their own history. ON-DEVICE SAFETY MONITORING A two-tier classifier flags concerning child utterances (self-harm, possible abuse, fear or threat, bullying, distress, substances, aggression) to the parent only — never to the cloud, never to us. Any reply can be reported for parent review. MULTIPLE PROFILES (Pro) Each family member gets their own history, settings, and safety state. CONVERSATION HISTORY Browse, resume, rename, or delete sessions. Full-text search and export are Pro. THEMES Five looks — Original, Storybook, Playful, Sunshine, Picnic — plus a gentle weather backdrop. EVIE PRO Monthly, Annual, or one-time Lifetime — all unlock the same Pro features: multi-profile, Storyteller co-create, Curious Scientist, the full Lessons catalog, history search and export, and per-audience extra instructions. Everything else — voice and typed chat, all audiences, Socratic / Storyteller / Bedtime, parent mode, allowed hours, safety monitoring, and the first lesson of every track — is free. REQUIRES iOS 18+ and at least 6 GB of memory. iPhone: iPhone 14 or newer, plus iPhone 12 Pro / 12 Pro Max / 13 Pro / 13 Pro Max (iPhone 15 Pro / 16 or newer recommended). iPad: M-series iPads and iPad mini (A17 Pro). Other devices show an "unsupported" screen. ========= Powered by Gemma (Google). Not affiliated with or endorsed by Google. "Gemma" is a trademark of Google LLC.

  • This app hasn’t received enough ratings or reviews to display an overview.

Read aloud, right where you need it. • "Read aloud" is now a button under each of Evie's replies instead of an item tucked inside a menu — one tap to hear an answer, tap again to stop. It dims while Evie is busy, so it's clear when it isn't available. • Fixed: after using Read aloud, asking a new question no longer pulls the chat back to the sentence it had reached. The new answer stays in view. • The age range each profile is set to is now always on screen, so you can tell at a glance which one Evie is answering as. • The way Evie is talking — Thinking, Science, Bedtime or Storyteller — now shows as a small badge on the mode button, so it's visible at any point in a chat, not only when it changes. • Starting a story now shows your own opening line in the chat, instead of Evie replying to a question that was never there. Still 100% offline and private — nothing your family says leaves the device. Thanks for using Evie!
