BrainFog is a private second brain you talk to. Speak naturally once, and BrainFog saves the detail with a timestamp. Later, ask in your own words and hear the answer back. No typing. No folders. No “Where did I write that down?” JUST SPEAK. THEN ASK. Use BrainFog for: • Parking spots, keys, and things you put somewhere “safe” • Appointments, tasks, and reminders • Passwords and other private details • Meeting decisions, follow ups, and ideas • Grocery lists, recipes, and instructions • Money notes, IOUs, and running balances • Doctor instructions, routines, and personal records • Birthdays, gift ideas, and details about people you care about • A private voice diary you can ask about later REMINDERS THAT STAY ON IT Say, “I have an appointment tomorrow at 4. Remind me at 2.” BrainFog suggests a reminder, and one tap sets it. Reminders work offline and keep alerting until you snooze or dismiss them. PRIVATE BY DESIGN Your saved memories stay on your phone. There is no BrainFog database of your life. No account. No sign up. No ads. Add Face ID or fingerprint protection for extra privacy. When AI is briefly used to transcribe or answer, the information is processed for that request and not retained by BrainFog. SPEAK YOUR LANGUAGE Use BrainFog in 50+ languages, including English, Hindi, Urdu, Punjabi, Arabic, Spanish, French, and more. Ask in your language and hear the answer in your language. YOUR DATA, YOUR CONTROL Review your memories in a timeline, favorite important entries, edit or delete anything, have entries read aloud, and export or import your data whenever you need to move or restore it. Your brain is brilliant at thinking and terrible at storing. Let BrainFog carry the little details. TRY IT FREE Explore BrainFog free for three days. A subscription is required afterward.
