AI performance reviews and goals that actually get run
Raw feedback from reviews is distilled into individual and company-wide reports that are ready to present, cutting the administrative work of each cycle.
Run 360s, peer reviews, upward reviews, self-assessments, probation check-ins and annual reviews with customizable forms and flexible workflows.
Set company, team and individual goals with auto-calculated progress, then include them automatically in review cycles.
Reminders and review tasks arrive where employees already work, with email automation for those who prefer it.
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.
