It’s been 14 years since my first submission to HN and I am so grateful to this community for all your feedback & help on my first company (Optimizely) and now my second one (Rewind). Today we’re introducing Rewind for iPhone - a truly personalized AI in your pocket. I’d love your feedback!

Browse & search for any word you’ve seen (including screenshots)

- Rewind automatically captures what you read in Safari and imports your screenshots.

- You can preserve & search for anything you’ve seen on your iPhone.

- This opens a new dimension of computing: time.

Summarize and ask any question using AI

- Rewind integrates with OpenAI GPT-4 to allow you to ask any question about anything you’ve seen.

- Create summaries, synthesize information across apps, or remind yourself how you know someone.

Private by design

- Private browsing in Safari is not captured.

- Using GPT-4 is optional and only the relevant text necessary to answer your question is used.

- Your data is not used to train AI models.

- All recordings are stored locally and only you have access to them.

Please let me know what you think!

“Private by design” is a killer feature for me. This kind of app could be absolutely nightmarish if all the data were stored and analyzed remotely. Thank you for building it this way!

It's powered by GPT-4 so it's not "private by design" by standards here:

From the post I replied to:

"Using GPT-4 is optional"

Yeah, if you opt in to using a cloud service, you'll be using a cloud service.

Optional for what? If you use Ask Rewind you currently need GPT-4. AI is the meat of this product.

I think they shouldn't tout privacy as a feature until their models go open source. If they did that what would they say then, "Now we're really private"?

Is a behind-the-scenes engineering blog post of the trade offs you made for iOS when compared to the macOS app available?

> Private by design

How are people supposed to believe you if your product is not open-source?

Wireshark? Little snitch?

(I work at Rewind) We even have a page talking about using Little Snitch for our mac app https://help.rewind.ai/en/articles/6831953-why-does-rewind-m... We'll have to update for our iOS app

Can you say more about what “using GPT-4 is optional” means? What features do I lose by not using GPT-4? How do I opt out?

You would lose all of the natural language q&a (ask X) which imho is the useful piece.

What data leaves my iPhone?
