An AI-native calendar that handles the heavy lifting and calculations, so you can put your intentions and reflections first.
Other AI calendars auto-book your day and hope you don't notice. TimeBox works with you — suggesting, reasoning, and never overriding your intentions.
Ask why your Tuesdays always run late, where your focus time went this week, or what's realistic to fit before Friday. AI answers from your actual history.
AI suggested something wrong? Accidentally deleted that dentist appointment? One tap and it's back — no stress, no scrambling.
Every change you make in TimeBox becomes a commit. Browse what you scheduled, moved, or deleted — and roll back to any point in your own timeline.
Log what actually happened: meeting ran 20 min long, skipped the gym, commute was brutal. A truthful record of where your time went.
AI chats get saved locally. Reflections write to plain markdown files you can open, edit, or back up without TimeBox ever running. Your thinking is yours.
TimeBox's code is closed source — but your data isn't locked in. It's just plain files on your disk. Show them in the terminal, back them up, or open them in any editor. Your data stays portable — even if TimeBox isn't running.
AI calls still hit remote LLM servers. Bringing more control over where AI runs is on the roadmap.
Link your Google Calendar in one click. Keep using the apps you already use.
Add, edit, and move events like normal. TimeBox quietly saves every version in the background.
At the end of the day, mark what ran long, what got skipped, what actually happened.
Made a mistake? Lost something? Roll back to any previous state, instantly.
You set intentions in the morning. By 6pm, half of them bent to meetings, moods, and life. TimeBox lets you close the loop — log what actually happened, see the gap, and notice the patterns.
The AI can reason about what it sees: "Your focus blocks rarely survive Monday afternoons" or "You consistently underestimate commute days by 25%." Insights, not orders. You decide what to change.
AI should help you think about your time — not make decisions for you.
Starting simple and local. Growing into something anyone can use.
Downloadable Mac app. AI sidebar that reasons about your calendar. Edit history with one-tap undo. Syncs with Google Calendar.
"Block 2 hours tomorrow afternoon for the product doc, before my 4pm." Type or speak — AI turns your intent into events you confirm before anything lands.
Stronger local-first guarantees: calendar data stays on your device, more control over where AI calls run, and nothing touches your calendar without you hitting "apply."
Edit your calendar by voice. Rewind from anywhere. Accessible beyond Mac desktop.
Smart suggestions about how you actually spend your time — and what to change.
Shapers are the early cohort: small batches, high-touch 1:1 onboarding with the founder, then hands-on with the MVP so we can build a great product. Drop your email and I'll be in touch when the next batch opens.
