AI THAT HELPS YOU LEARN • Chat: ask questions, attach documents, and get step-by-step math • Agent IDE: describe a change and the agent reads, edits and runs files in your project, with restore points • On-device models are free and work offline EDSGER PRO (OPTIONAL SUBSCRIPTION) • Dijkstra Super Fast 1.0, a faster cloud model for Chat and the Agent IDE, with a monthly AI allowance • Photos in Chat with Dijkstra • Bring your own OpenAI or Claude API key • Push projects to your GitHub account • A custom Chat note and extra colors Pro Plus includes three times the Pro allowance.
