Rewisp gives your Mac a memory. It reads your screen text on-device and remembers it for you. Catches promises like "I'll send it Friday" and reminds you until it's done. Ask "what changed since Tuesday?" and see exactly what's new. Search by meaning, not just words. Tracks numbers like weight or grades over time. Fills forms from your saved details — never passwords. One quiet 9 PM summary each day. Fully private: screenshots never saved, only text stays on your Mac.

On-device screen reading is the right call, but I am curious about the practical cost — what does continuous OCR do to battery on a laptop that is unplugged all day? And can I exclude specific apps entirely (password managers, banking) so they never even hit the local index?
Rewisp
@reallynattu Good catches! The computational cost is little to none. In the 2 weeks of development/testing phase, my computer's battery performed the exact same. I even wrote a benchmark test to get real numbers and on average the program effected my computer's battery level by 1.1%. And also yes, you can blacklist apps and websites on the dashboard so they are blocked before even trying to get stored(the app automatically has some built in but is super customizable).
What does the always-on screen reading do to battery and CPU on a laptop? I like the idea of asking "what changed since Tuesday" but I'd want to know the cost of having it watch everything all day.

@talhakhalidmtk Great question!
It isn't recording, which is the main thing. There's a cheap check twice a second for which window is frontmost, and it only actually captures on a trigger: you switch apps, a URL changes, you stop scrolling, or a 60 second heartbeat. Unchanged screens get dropped by a thumbnail diff before OCR even runs, so most heartbeats cost nothing.
When it does capture, OCR is Apple's Vision framework running on device and hardware accelerated, about a second, and only on the display holding the frontmost window. There's no video encoding anywhere, which is the expensive part of screen recorders. It's text only.
It also fully stops after five minutes of no input, and when the screen is locked or the display sleeps, so it isn't doing anything while you're away.
Measured on mine right now it sits at basically 0% CPU between captures with a short spike during one.
nice idea, do u plan to release a similar version for Windows as well?
Rewisp
@luca_ardito Yes! I'm currently taking feedback and improving my plans and going to make a windows version very soon!
The semantic search feels surprisingly accurate for just text matching, and catching commitments like "I'll send it Friday" actually held up across a few days. The nightly summary at 9 PM is a nice touch without being noisy.

@yorgan47831 Thank you for the kind words :)
Would love a way to mark something as "do not track" when I'm working on sensitive stuff like medical forms or legal docs. A quick keyboard shortcut to pause Rewisp for 15 or 30 minutes would feel really natural and keep the privacy promise even stronger.

@yasinerhalg3oh Thank you for the kind words!
As a fellow solo dev, the privacy-by-construction bit (text-only, screenshots discarded on the spot) is what makes this trustworthy vs a plain screen recorder. One thing I always hit shipping Mac apps though — the screen-recording permission prompt on first launch scares a chunk of users off. How are you handling that onboarding moment so people don't bounce before they get to the value?
Rewisp
@lennoxbeflying This is still an issue I am working on trying to fix. I would love to connect outside of this and discuss/collab more on this issue.
Congrats on the launch and #5th rank on Sunday.
Love the promise-catching idea. that's the stuff that always slips through the cracks. Does it handle commitments made in voice memos or dictated text, or only typed content?
Rewisp
@kbaqeri Thank you!
It currently handles everything that it saw on the screen, no audio/dictated content can be detected yet, but it is in the future improvements.
