Winner CTF

WINNER CTF Field Kit is an offline capture the flag companion designed for both live competitions and structured training. It combines practical utilities, organized workspaces, and built-in challenges into a single focused tool for CTF players. In Event Mode, create a workspace for each competition and track challenges as you investigate and solve them. Add notes, save decoded outputs as snippets, and keep everything organized in one searchable place. Built-in tools such as base encoders, cipher utilities, hash generators, text analysis, and a hex viewer help you process data quickly during gameplay. All tool outputs can be saved and linked to specific challenges. In Training Mode, practice with a large set of offline challenges across categories like cryptography, forensics, web concepts, logic, and simulated reverse tasks. Each challenge includes structured prompts and progressive hints. Flags are verified locally for a self-contained learning experience. A built-in notebook allows you to record observations, document techniques, and build your own reference system. Progress tracking provides an overview of completed challenges and skill development without relying on leaderboards or external accounts. An optional AI Coach can be enabled with your own API key to generate hints and explain concepts for training challenges. This feature is entirely user-controlled and not required to use the app. WINNER CTF Field Kit is fully offline by default. No accounts, no cloud dependency, and no external services are required to use the core features. It is built as an educational and organizational companion for capture the flag participants who value clarity, speed, and structure.
