Sema is private AI memory for your iPhone. Chat naturally, and Sema can save useful facts locally so later answers have more context. Ask about something you mentioned before, review what was saved, delete memories you do not want, or clear all local data from Settings. WHAT SEMA DOES - Private AI chat - Local conversation history - Automatic local memory for durable facts - Memory overview with source statements - Local memory search for follow-up questions - Permission-gated access for device sources such as Contacts, Calendar, Photos, Location, and Reminders - Apple Foundation Models first on supported devices - Optional on-device Gemma model download when Apple Foundation Models are unavailable - Optional public web search with Sema Pro PRIVATE BY DESIGN Sema has no account and no server-side copy of your chats or memories in this build. Conversations, memories, local search data, and permission history stay on your device. The developer cannot read your chats or memories. Sema may send aggregate product interaction analytics, such as app opens, onboarding completion, model availability, chat sends, response success or failure, and memory created or deleted. Analytics do not include chat text, memory text, names, contacts, calendar titles, locations, prompts, generated answers, or other private content. SEMA PRO (OPTIONAL SUBSCRIPTION) Sema is fully usable for free. An optional auto-renewable subscription, Sema Pro, adds public web search for questions local AI cannot know yet — $4.99/month or $24.99/year. Only sanitized public search queries leave the phone; saved memories and chats stay private in Free and Pro. Subscriptions auto-renew unless turned off at least 24 hours before the end of the current period. Payment is charged to your Apple ID. Manage or cancel anytime in your App Store account settings. IMPORTANT AI answers may be incomplete or incorrect. Verify important medical, legal, financial, safety, or time-sensitive information before relying on it.

Verdict
