Google's agent-first development platform for building and shipping software with AI agents
A desktop app, a full agentic IDE, a terminal-first CLI, editor extensions, and an SDK let you run Antigravity agents wherever you already work.
Group conversations into Projects and run several local agents at the same time, across multiple workspaces, rather than one at a time.
Agents produce designed artifacts such as plans and comprehensive verification tests so output can be reviewed, not just accepted.
Runs on Google's Gemini model line, including releases such as Gemini 4 Carbon, Gemini 4 Argon, and Gemini 3.8 Flash.
Free AI flashcard and study tools for students
Upload up to 30 files and Kai instantly produces notes, flashcards, summaries, and practice resources from them.
Convert Quizlet, Kahoot, Wayground, and YouTube content, or record live lectures to generate notes and study sets.
Upload class files to get a study plan and exam prediction that highlights what your professor emphasizes most.
Kai quizzes you by voice and can turn any note or flashcard into a podcast for study on the go.

#1
Massive library of shared academic notes paired with AI study tools, but less focused on flashcard creation.

Offers a more mature polished AI-native coding experience, but lacks Google's specific native multi-agent command center ecosystem.

Enables rapid full-stack app building and deployment entirely in the cloud, but offers less granular local agentic control.
Gamified AI study application converting notes into flashcards and quizzes, but with a more playful interface.
Deeply reads entire codebases to execute complex multi-file tasks, though integrated as an IDE plugin rather than standalone suite.
SpecialistComprehensive student study platform specialized in solving complex homework and exam prediction, but less focused on flashcards.
Delivers robust spec-driven engineering and autonomous verification workflows, though configured differently than Google's developer platform.
Cognition's autonomous software engineer that ships real pull requests

Interactive AI learning platform turning course materials into flashcards and quizzes, but with more video explanations.
Converts notes and PDFs into interactive flashcards and audio podcasts, but less established brand presence.
Free / Open-sourceOpen-source development environment running multiple CLI coding agents in isolated git worktrees, but requires manual setup.
