    Hey HN! We’re open-sourcing highlight.io (https://github.com/highlight/highlight), a session replay and error monitoring tool. Highlight.io gives you a high-precision video-like replay of what users are doing when an error or exception occurs in your web app, along with a full-fledged error monitoring experience (similar to bugsnag, rollbar, etc..). The main value prop of highlight.io is that we help you understand the full context surrounding an error and allow you to drill down to the code path that a user invoked (i.e user clicked button X, sent network request Y, and…

    Notate.so▲101

    Hey all :) I noticed the development on the Notion web clipper chrome extension is kinda slow, so I built a better one. It works on any web page, any youtube video, and any PDF. Features: - highlight + note + collections - auto-scrollback to your highlights (page automatically scrolls to the text you highlighted and it works on LLMs web interfaces) - automatic sync to Notion (+page+dbs creation) - reminders: the app pings you with an email to review and delete your already-checked highlights (you set the ping period) Let me know what you think.

    Here's the website: http://markup.io/ We created MarkUp at Medium to help make the QA process better for sites we're working on. Grab the MarkUp bookmarklet, go to some page in your browser, then click it to draw on the page. Publish to make a link you can share. We've tried similar tools like BounceApp, Notable, and Skitch. Everything else we found is screenshot-based or takes us out of the browser. We wanted something that felt quicker than screenshots and more integrated with the browsing experience. Instead of taking a screenshot, MarkUp snapshots the DOM in the current page, strips the…
