UpCat
Free browser extension for Upwork freelancers — drafts cover letters from the job post and fires real-time alerts on new matching listings.
About UpCat
UpCat is a free browser extension for Upwork freelancers that does two jobs: drafting proposals and catching new listings early. The proposal writer reads the job post you are looking at and drafts a cover letter that references the client's actual project, which you then edit into your own voice — the point being to remove the blank page rather than to submit machine text, and the vendor is explicit that generic ChatGPT-style proposals are what it is trying to avoid. The second half is arguably worth more: real-time job alerts fire when a matching listing appears, and on a marketplace where proposal position and response time materially affect win rate, being early to a well-fitting post is a structural advantage over writing a better letter to a crowded one. Two free utilities round it out — an Upwork text formatter, since the platform's proposal field handles formatting idiosyncratically, and a CPM calculator. The extension works in Chrome, Brave, Edge and Opera. It has more than 6,000 Chrome users and a 4.8 rating across 21 reviews. The vendor describes it as always free, which is unusual in a category where every comparable tool is a subscription, and there is a blog covering Upwork tactics.
