Huddlekit
Modern feedback tool for websites and creative assets
About
Huddlekit is a website annotation and QA tool for designers and developers. Pin comments on live pages, inspect CSS instantly, and compare breakpoints side-by-side without leaving the tab. It reduces back-and-forth during reviews so teams catch issues sooner.
Paste any URL to start a review. Switch between Comment Mode, Inspect Mode, and Canvas View to annotate, check styles, and compare responsive breakpoints. Share a single link with teammates or clients to collaborate in real time, with every comment threaded by project.
Share a review link and guests can leave comments without creating an account. Invited teammates get full workspace access, so clients can chime in quickly while your team manages projects in the background.

We don't use Slack here. We consider it a productivity killer. It encourages always-on behavior. What we do is use different tools that help slow down the pace of conversation and facilitate people thinking through things more deeply before they post them.
Async-first with Basecamp and no notifications enables deep work — communication tools should serve the builder, not the other way
Teaching.com runs on Basecamp with notifications disabled by default; Slack is kept only in its free tier (90-day message history) for true emergencies. The intent is to protect large blocks of uninterrupted deep work time. New hires are onboarded into the system with explicit instructions to disable all notifications — a cultural forcing function the company attributes directly to the quality of its products and the longevity of its team.
We experimented to some users actually the threshold was three times a day and then if you try to allow them to watch it more frequently then the retention drops but actually one to three times actually retention and engagement improved it's completely counterintuitive.
Rewarded Video Improved Retention — But Only Up to 3 Times Per Day
Anton's team found that adding rewarded video ads (earn 1 sweatcoin per video, optional) improved retention for about 20% of users — but only when capped at 1-3 views per day. Above that threshold, the effect reversed. This maps directly to gaming industry knowledge around rewarded video mechanics, where the reward loop adds value until it becomes noise. The lesson for non-gaming apps: the right monetization can actually improve engagement metrics, but dosage matters more than availability.
There's a play for whatever you're stuck on.
