Bitwise is a coding interview study app built around short, guided problem-solving sessions. Instead of revealing a finished answer, its Code Builder puzzles ask learners to make decisions one step at a time, then explain how each choice moves an algorithm forward. Users can work through data structures and algorithms, check solutions against examples and tests, and reason about time and space complexity. Hints are available, and completed puzzles return on a spaced schedule for review. The listing describes support for languages including Python, JavaScript, TypeScript, Java, C#, Swift, C, C++, and Go. Three starter puzzles are free; a membership unlocks the full library and ongoing additions. Membership pricing was not captured.
