A: Hi naturepharma.me, thanks for reading through the Q&A! Yes, Contral's Build mode can build an app from scratch. Open an empty folder, describe what you want, and it creates the files, writes the code, and can run install and dev-server commands with your approval. Bigger apps may take a few messages. Usage is tracked per feature rather than as one shared credit pool, and each message you send counts once no matter how many steps the agent takes: AI (Build) messages are 500 per day on Tier 1, 1,000 per day on Tier 2, and unlimited on Tier 3. Learn Mode explanations are unlimited on every tier. Teaching cards on Kilo Code or Cline edits follow the same daily numbers (500 / 1,000 / unlimited). Deep dives are 10 / 20 / 200 per day, and codebase analyses are 5 / 10 / 100 per month. Messages that use your own API key are unlimited on every tier. Premium models are included on Tier 3. You can see Build mode in action in our IDE demo: https://youtu.be/LY8v5qWLnb4
