Great help to review books

I imported my kindle highlights, as many others. Now I daily review some highlights (thanks to a dashboard, I am motivated). And where I didn't create highlights, as I only listened to the audiobooks, I get the highlights from others. It also allows to create beautiful quotes. It adds the book cover and matches quote and background with colours found on the book title! Really nice!

👍 Pros: Review books|Beautiful quotes|Dashboard motivates

It's probably time to rethink "Building in public"
I used to "build in public" with my first app 2 years ago, KTool[0] But back then most indie hackers only share numbers in their monthly reports, me included[1]. And it's not just MRR screenshots with no content. Many shared their lessons, experiments, personal struggles... I can't stress enough how helpful this was. To me and to many founders I've talked with. It helps us with the loneliness and we learned from... - Source: Hacker News / 8 months ago
Marketing for Product-Obsessed Developers
- If you collect email addresses, do not promote the main product after at least 3-4 product email updates of that free tool. People _might_ remember your free tool, but almost never remember your main product. Here are 2 examples: 1. I build a tool to send web articles to [Kindle called KTool](https://ktool.io). It supports multiple type of content and so I figured I could build free, standalone tools for each of... - Source: Hacker News / over 1 year ago

Exporting Mac OSX Book Highlights into an Obsidian Vault or Markdown Files
The only highlights that Readwise retrieves semi-automatically are from the books I buy from Kindle, by going into the Readwise app and clicking a button. If I upload them to Kindle or need highlights from the Apple Books app, I have to open the book, go to my highlights, select them all, and then email them to a Readwise email address. - Source: dev.to / 5 months ago
Show HN: I combined spaced repetition with emails so you can remember anything
Readwise also has this feature. I get a daily email with a random assortment of highlights that have been pulled in from multiple sources (Reader, Notion, Kindle, etc.) The product benefit in their case is that it's kind of like Zapier, but for notes. https://readwise.io/. - Source: Hacker News / 6 months ago
