Brain Master: Private AI Notes

Brain Master is a private AI notes app and reminder app that runs entirely on your device. Take notes, set reminders, and even ask your notes questions — offline, with no account, and your notes stay on your phone. A truly private notepad and second brain.

★ WHY BRAIN MASTER? ★

🧠 On-device AI notes — Semantic search, an "Ask your notes" AI chat, and note summarization run on your phone; your notes are not sent to the cloud for these features.

🔒 Private notes, no account — No sign-up, no server. Your notes, reminders and images stay on your device. You can optionally back up to your own Google Drive if you choose.

📴 Works fully offline — On a plane, on the subway, or with no signal, your notes app and AI features keep working.

⏰ Natural-language reminders — Type "dentist tomorrow at 9" and Brain Master sets the reminder for you. A fast reminder app for everyday life.

🔎 Semantic note search — Finds the right note even when your words don't match exactly — far smarter than a normal notepad search.

🖼️ Image-to-text (OCR) — Turn text in a photo into an editable note in seconds.

🏷️ Topics & priorities — Organize notes with tags and priority so your second brain stays tidy.

★ WHAT IS "ASK YOUR NOTES"? ★
Ask a question in plain language and Brain Master finds your relevant notes and answers using on-device AI — showing you the source notes. Like a private AI chat for your own notes, working offline on your phone.

★ PERFECT FOR ★
• Quick notes, to-do lists and daily reminders
• A private, offline diary or journal

• Building a personal knowledge base and second brain
• Anyone who wants a private notes app that keeps data on-device

★ PRIVATE & OFFLINE ★
Looking for a private, offline alternative to cloud note apps like Google Keep? Brain Master keeps your notes on your device — not on our servers. Free.
