What's New in AI Note Taking & Voice Memo
1.2.0
August 1, 2026
Two big additions in 1.2: TAKE IT ANYWHERE Type the question you are about to ask any other AI, and Second Brain composes a ready-to-paste prompt from your own notes, with a review list so you choose exactly which facts to include. Your context, in every chatbot. A WARMER WELCOME A new first run helps you set up your Second Brain in a moment and add your first thoughts, so it is useful from day one. Plus polish and fixes throughout. Everything still runs fully on your device. Also new: ask Siri to capture a thought, ask your notes, or take your context anywhere — and find your notes in iPhone Spotlight search, a private on-device index you can turn off. Also fixed: read-aloud could stay silent after you used voice input — it now speaks every time. Also: if a call interrupts dictation, the recording now ends cleanly and keeps what you already said.
