Pros and cons

Google Antigravity

Pros

  • Free Individual plan with unlimited Tab completions and Command requests.
  • Offers Gemini, Claude and GPT-OSS models in one tool.
  • Parallel agents and background subagents in isolated Git worktrees.
  • Artifacts (plans, diffs, browser recordings) make agent output reviewable.
  • Available as app, CLI, IDE extensions and Python SDK on macOS, Windows and Linux.
  • Enterprise controls include SSO, VPC Service Controls and regional data residency.

Cons

  • Pricing page gives no numeric rate limits or credit amounts, so quotas are hard to predict.
  • Prices for Google AI Pro and Ultra are not shown on the Antigravity pricing page.
  • Weekly and five-hour limits apply, with Gemini and Claude/GPT usage tracked separately.
  • Product surfaces and release cadence are fast-moving, and some enterprise IDE features are still in Preview.

Gemini Notebook

Pros

  • Answers cite the uploaded sources, so claims can be checked against the original text
  • Free Standard tier with 100 notebooks and 50 sources per notebook
  • Wide range of outputs, including Audio Overviews, Video Overviews, mind maps, flashcards, quizzes and slide decks
  • Accepts PDFs, websites, YouTube videos, audio files, Google Docs and Google Slides
  • Available on web, iOS and Android, and synced with the Gemini app

Cons

  • Works from the sources you add and is not built for live web news search
  • Higher limits require a Google AI subscription; Ultra starts at $99.99 per month
  • The cloud computer for code execution started with Ultra and Workspace AI Ultra Access customers, with Pro rollout still described as upcoming
  • No public API for the consumer product, and the renamed brand can make older guides and app listings confusing
