FreelanceOS is a free browser-based dashboard that handles the admin side of freelancing. It centralizes client tracking so you can see deal status at a glance without maintaining spreadsheets. The main time-saver is one-click AI follow-up generation — instead of staring at a blank email, you get a draft based on the client context you've already logged. There's also a lightweight note-capture tool for grabbing details during or after calls before they're forgotten. It's a lean tool aimed at solo freelancers who want to stay organized without paying for a full CRM.
