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.
All-in-one AI PDF tools to edit, convert, compress and translate documents
Modify text and images directly inside a PDF and translate document content into many languages while keeping the original page layout intact.
Shrink, merge and split PDFs so large documents are easier to store, share and organise, with compression that aims to preserve visible quality.
Convert PDFs to Word, Excel, PowerPoint and JPG, and convert Word, Excel, PowerPoint, JPG and EPUB back into PDF.
An AI grammar checker that finds grammatical errors and spelling mistakes across multiple languages, plus a paraphrasing tool for fast rewriting.

#1
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.
Deeply reads entire codebases to execute complex multi-file tasks, though integrated as an IDE plugin rather than standalone suite.
Free online OCR that turns any image into editable text in seconds
Delivers robust spec-driven engineering and autonomous verification workflows, though configured differently than Google's developer platform.
A free, AI-powered PDF editor for every device
Cognition's autonomous software engineer that ships real pull requests
AI-powered PDF editor for Windows, Mac and iOS

Free AI-powered PDF editor, converter and reader for every device
AI translation for text, images, documents and speech in 100+ languages

Cross-platform PDF editing with GPT-powered AI for reading, translating, and signing documents
