In their own words
Auto Browser
Auto Browser is a free Chrome extension that uses an AI agent in the browser’s side panel. It reads a webpage’s accessibility tree and can click, type, scroll, navigate, fill forms, and handle research tasks described in plain English. Pages exposing WebMCP tools can let it use those tools instead of the page DOM. Supported providers include Chrome Built-in AI (Gemini Nano), Google Gemini, OpenRouter, and local OpenAI-compatible endpoints such as Ollama and LM Studio. You can change providers during a conversation without losing its history. Write actions require approval, arbitrary JavaScript prompts for approval, and banking, government, and healthcare origins are blocked by default. The extension is free to install at free; Google Gemini and OpenRouter charge per request using your API key. Chrome 126 or newer is required for basic use. Attachments can be images or audio up to 10 MB each.
UseAgent
UseAgent provides AI coworkers that research, prepare reports, and handle follow-ups using company knowledge and connected tools. Teams can add documents and instructions, review proposed knowledge before sharing it, and optionally use team memory. Agents can run recurring workflows hourly, daily, or weekly and post results to Slack. They can also create editable DOCX, XLSX, and PPTX files for export to Office or PDF. The cloud plan lists Chat, OpenCode, Claude Code, Codex, and Pi as agent engines. Integrations include GitHub, Slack, Linear, Gmail, Notion, HubSpot, Google Drive, MCP servers, and PostgreSQL. GitHub access currently supports reading pull requests, issues, and commits; write operations are marked as coming soon. Agents work in isolated Linux environments, and teams can inspect saved requests, tool calls, approvals, and results. Users can require approval before sensitive actions. Cloud and self-host plans are free, but users supply their own AI provider keys and providers bill for model usage and computer time. Bots and routines are planned for self-host v0.0.4, while the public repository is at v0.0.3.
