The Gap
Why Today’s Browsers Fall Short for Agents
Traditional browsers are passive
Chrome, Safari, and Edge just display pages. They don’t act, automate, or think. Every task requires your manual input.
AI patches are bolted on
Microsoft Copilot and Perplexity Comet add AI as an afterthought. The result? Slow, unreliable features that drain resources.
Developer tools have high barriers
Browser Use and Anchor Browser are powerful — but only if you can write code and pay enterprise prices.
The Answer
Built for Agents, Designed for Humans
Tabbit is not a traditional browser with AI added later. It is an AI-native browser where the agent is the core engine. From the ground up, every interaction is designed around autonomous task execution.
Zero Setup
No API keys. No coding. No configuration. Download and start commanding your agent in natural language.
Truly Free
Unlike ChatGPT Atlas ($20/mo) or Genspark ($25/mo), Tabbit offers core agent features at no cost.
Cross-Platform
Available on macOS and Windows. Not locked to a single ecosystem like Atlas (Mac-only at launch).
Capabilities
What Your Agent Can Do
Agent Mode
Give a natural language command and watch Tabbit navigate, fill forms, extract data, and deliver results autonomously.
Omnibox
One input for URLs, searches, and AI commands. Type @ to reference any tab, screenshot, or file as context.
Skills
Save reusable prompts and automations. Use / to trigger them instantly. Share and discover skills in the community plaza.
Smart Workspace
Vertical tabs with AI-powered grouping. Knowledge-base bookmarks that stay accessible even if the original page goes down.
