Small studio, real software.
Cosmos Factor is a small software studio in Curitiba, Brazil. We build products around AI workflows and automation, software people use at work every day.
We keep the team small so decisions stay fast and the product stays lean. The same people who design the software build it and run it, from internal tools to production SaaS.
The studio is led by founder Luan Estradioto, a Full Stack Developer and AI Engineer who stays hands-on in everything we ship, from code to support.
Products
Two products lead the studio: Contra Glosa, built for physicians, and WiFi Tracker, for anyone who works on a Mac.
Live
Contra Glosa
Contra Glosa is a SaaS that automates appeals for denied medical claims, built for physicians in medical cooperatives and compatible with Unimed Curitiba. It imports denials and statements, drafts each justification with AI and, once the doctor approves, sends the appeal and tracks the outcome. It runs in production today, with paying pilot users.
- AI-drafted appeals with full case context
- Deadline tracking with a priority queue
- Encryption, PII masking and hosting on AWS in Brazil

WiFi Tracker
WiFi Tracker is a lightweight macOS app that logs your work sessions from Wi-Fi presence, so you can stop tracking hours by hand. Everything stays on your machine: local-first and private by design.
- Automatic session tracking from Wi-Fi presence
- Local-first: your data never leaves your Mac
- No timers to start, no timesheets to fill
