The problem: Much of professional work is the same task done again and again in one person’s particular way: meeting minutes, client briefs, reports. Generic AI tools don’t know that way, so people spend their time rewriting drafts that sound nothing like them. Their method, the thing that actually has value, stays in their head. It can’t be handed off, scaled or earned from. What Persuna does: Persuna is an AI assistant that lives on your screen and learns how you work. You teach it with your own before-and-after examples, by answering a few questions, or by doing the task once while it watches. It turns that into a skill, tests each version on examples it hasn’t seen, and every correction you make becomes a new rule. It then drafts real work from your notes, PDFs, photos or voice notes and checks every statement against the input. Nothing goes out without your sign-off, and it earns more autonomy only as its record proves it. On Mac and Windows, you hold one key in any app and just talk. Persuna marks the steps on your screen, draws diagrams as it explains, and in Work mode quietly learns your steps and helps when you’re stuck. Once a skill is verified, you can rent it on the marketplace. Others pay for your results without ever seeing your method, so one person’s expertise can do many people’s work. It’s built on Meta’s Muse Spark, SAM 3.1 and the Files API.
