Scribbble is a screen annotation application specifically designed for Mac users, allowing them to draw, highlight, and annotate directly on their screens. This tool is particularly beneficial for a variety of users including teachers, streamers, YouTubers, designers, and sales teams. The app facilitates live presentations by enabling users to make annotations over any application, such as slides, web browsers, Figma, and video conferencing tools like Zoom and Google Meet, all without the need for additional plugins or setup.
On the business side this is a classic lean indie product: a focused Mac utility in a clear niche (screen annotations) that has already converted paying customers and is growing quickly month-over-month. The combination of early revenue, rapid growth, and a high margin points to low operating costs and product-market fit among a small initial audience. For someone weighing the opportunity, the flip side is the absolute scale today — revenue is still modest — so the path to meaningful ARR will depend on distribution (macOS reach, partnerships, App Store visibility) and repeat purchase or upgrade behavior. Being Mac-only narrows the addressable market but can also allow for tighter product focus and higher monetization per user if executed well.
A judgment from project data — not a user review.
