Someone tells you they're starting a new role, moving away, or going through a rough month. You mean to ask how it goes. Then a few busy weeks pass, and the next catch-up starts over from "so, what's new?" Bondsai is a private relationship journal for exactly those moments. Save the few things you don't want to lose. Bondsai keeps them with the person and brings them back on the rhythm you choose, so you can follow through and pick up where you left off. EVERYTHING STAYS ON YOUR PHONE Bondsai is local-first by design. Your people and notes live on your device. Nothing is uploaded to our servers, because we don't have any. No account, no tracking, no AI reading your life. Backups go straight to your own iCloud. SAVE WHAT MATTERS, IN SECONDS • A note in your own words, kept with the person it belongs to. • The question you want to ask next time, saved as a follow-up. • Birthdays and important dates. • The details a good friend holds onto: family, pets, how you met, what's going on right now. IT COMES BACK WHEN IT COUNTS • Follow-ups return on the date you choose. • "This season" shows what's coming up before it passes. • Gentle reconnect rhythms for each person, set by you. A quiet chance to say hello. • A timeline for each person, so every catch-up can continue from the last one. CALM ON PURPOSE • No streaks, no scores, no red badges. Bondsai doesn't grade your friendships. • You decide who to add, what to save, and when to reach out. • Import from your phone's contacts once if you like. Bondsai reads them a single time and never syncs. • Your data is portable: export and import anytime. Bondsai is a quiet place to keep the threads between conversations, so your actions can reflect the care you already feel.

About

VoiceBrain

VoiceBrain helps you capture ideas the moment they strike. Speak a thought — or type it — and VoiceBrain transcribes it, understands it, and files it as a task, note, reminder, or calendar event, automatically. Just talk (or type): • "Remind me to call the dentist tomorrow at 10" becomes a reminder. • "Buy oat milk and coffee" becomes a task on your list. • "Team sync Thursday at 3" becomes a calendar event. • "Idea: a walking tour app for Berlin" becomes a note. Everything you capture lands in one place, sorted by type, so you act on it later instead of losing it. Features • Capture by voice or text — tap to record, or type it out, and mix both in one entry • Automatic transcription and smart sorting into tasks, notes, reminders, and events • Shared spaces — keep the things you and someone else both need in sync • Live co-editing — edit a shared note together in real time • Apple Calendar integration, so spoken events join the rest of your day • Sign in with Apple, no separate password VoiceBrain is a focused, private tool: no ads, no third-party trackers. Your recordings and transcripts are used only to give you back organized entries.
