The idea that would've made the meeting — gone by the meeting.
Your sharpest thinking happens in the gaps: the commute, the walk between calls, the shower before a big review. But if it's not on the calendar, it doesn't exist — and by your next meeting it's gone. Thought Spark catches it in five seconds and turns it into a scheduled next step.
For you, the calendar is the boss
You've made peace with a hard truth: anything not on the calendar doesn't happen. The problem is that ideas don't arrive during a calendar slot — they arrive between them, when your hands are full and your next meeting is in four minutes. So the good ones evaporate, and you find out months later when someone else shipped the thing you thought of first. The gap isn't ambition; it's the ten seconds between having the idea and getting it somewhere real.
Between two meetings, start to finish
Catch it in the hallway
Idea between calls. One tap, say it — "we should pilot async standups with the platform team" — saved and titled in seconds.
Make it meeting-ready
Got a spare few minutes? Clarify structures it into a crisp concept — the what, the who, the why — ready to pitch.
Sanity-check it
Research surfaces prior art and risks with sources, so you walk in informed instead of hand-waving.
Put it on the calendar
Act writes "draft the pilot proposal, Wed 2pm" into Reminders and Calendar — where, for you, things become real.
The step that matters most for you: Act
Most idea tools end at storage — the exact point where your ideas already die. Act is the opposite: it takes a thought and writes a concrete next step and a focused work-block straight into Apple Reminders and Apple Calendar — the tools you already run your day in. Nothing to copy, nothing new to open, nothing to babysit. The idea stops living in yet another app and starts competing for your attention alongside everything that actually gets done.
An idea on your calendar is a plan. An idea in a notes app is a maybe.
Fair questions
I don't want another app to check
Then you'll like the design: the output leaves the app. Your next step lands in Reminders and Calendar — where you already look — so there's nothing new to monitor. Thought Spark is the on-ramp, not another inbox.
How is this different from Otter?
Otter is built to transcribe meetings. This is built for your own between-meeting thinking, and for turning a thought into a scheduled action rather than a transcript. Different job. See the Otter comparison.
Does it really write to Reminders and Calendar?
Yes — Act creates the next step and work-block directly in Apple Reminders and Calendar on your iPhone, so ideas show up next to everything else you track.
Is my thinking private?
Your ideas stay on your device, sent for AI processing only when you run a feature, never used to train models. Details in the privacy policy.
