Voice → the gist
Walk. Talk.
See the gist.
Speak your thinking out loud. ThoughtSift sifts the noise into the gist — a clean, readable set of the key points of what you said. Want a picture? Turn it into a hand-drawn diagram on demand.
How it works
From a ramble to a diagram in three steps
Talk it out
Tap record and think out loud — on a walk, in the car, between meetings. The screen can lock; the thought keeps going.
Sift the noise
ThoughtSift transcribes on-device, then clusters the rambling into clean threads.
See the gist
A hand-drawn diagram of your thinking, with the one idea worth keeping.
The gift
One thought, drawn seven ways
ThoughtSift picks the shape that fits what you said.
Private by default
Your voice never leaves your phone
- Transcription runs on-device by default.
- Only the text transcript builds your sift — never the audio.
- Nothing is public until you create a share link.
Share
Send the sift, not the recording
Every sift becomes a link. Whoever opens it reads the gist — no app needed — and the link unfurls as a proper preview card in WhatsApp or iMessage. Made a diagram? It travels with the link too.
Your transcript stays off the share unless you switch it on. Add a PIN if it’s for one pair of eyes.
- Include still image on
- Include transcript off
- Protect with PIN off
Capture
Thoughts don’t wait for the app to open
Start anywhere
The iPhone Action Button, a home-screen widget, or the app — one press and you're recording.
Screen locked, still listening
Lock the phone mid-thought. Recording carries on until you're done.
Pause now, resume later
Half a thought is still a thought. Drafts survive relaunch — append to them and re-sift.
