About Starizon AI: AI Agent for Auto Browse & Automation
🔥 Starizon is an AI assistant built into your browser's side panel, combining web page understanding, browser automation and personal knowledge management. Describe your goal, and Starizon clicks, types and fills in forms for you in the browser you're already signed in to. It draws on page reading, tab and bookmark management, your Knowledge Base, web search and your connected apps to plan and complete multi-step tasks on its own.
Shortcut: Alt+Shift+S (Command+Shift+S on Mac).
✨ What's new in 5.0
✔️ One unified assistant: Features that previously required separate commands such as /tabs, /bookmarks and /highlight now share a single entry point. Describe a task in natural language, and Starizon selects the features it needs and determines the order in which to run them.
✔️ Introducing Spaces: Keep a project's web pages, files, Knowledge Base content and conversations in one place, and reuse them across conversations.
💪 Key features
1️⃣ Cross-feature tasks in a single request
Starizon brings the capabilities of your browser together in one assistant. Describe the outcome you want, and Starizon plans the path, chooses the right capability for each step and passes each step's result directly to the next, so you never have to switch between tools and commands.
✔️ Capabilities it can combine:
· Browser automation: Click, type, fill in forms and page through results on sites you're signed in to
· Page reading and highlighting: Read the pages you have open and highlight key points in the original text
· Tabs and tab groups: Open, group, deduplicate and close tabs in bulk
· Bookmarks: Find bookmarks and open them directly, or bookmark pages into a folder of your choice
· Knowledge Base: Save pages, highlights and answers, then get answers grounded in your saved material, with sources cited
· Web search: Search and read public web pages for up-to-date information
· Writing assistance: Summarize, extract key points, rewrite, proofread and compare alternatives
· Apps: Work with connected services such as Gmail, Notion and Google Sheets
· MCP tools: Call tools from the MCP servers you have added and enabled
✔️ Example requests:
· Price comparison: “Find this product on two other shopping sites, open the three lowest prices in one tab group, and save the comparison to my Knowledge Base.” (Browser automation + Tab groups + Knowledge Base)
· Reading digest: “Open the articles I bookmarked this week, highlight the key points in each, then save them to my Knowledge Base.” (Bookmarks + Highlighting + Knowledge Base)
· Trip planning: “Plan a day-by-day Italy itinerary from the pages I've saved and put it into a Gmail draft.” (Knowledge Base + Gmail)
· Competitor analysis: “Read the competitor pages in this tab group, build a comparison table of pricing, features and limits, and add it to my Google Sheet.” (Tab groups + Page reading + Google Sheets)
· Tab cleanup: “Close duplicate tabs, bookmark the articles into a ‘Read Later’ folder, and group the rest by topic.” (Tabs + Bookmarks)
✔️ Adaptive planning: Starizon decides each next step based on the actual result of the previous one. When the current page lacks the information needed, it searches the web automatically. When it reaches a login, a human verification check or another step that needs you, it pauses, hands control to you and resumes once you're done.
✔️ Your personal context: Reference a Space's project materials in the same request, or invoke a Skill to apply your preferences and working methods.
✔️ Full transparency: Every step and its result appear in the conversation in real time, including the pages read, the tools used and interim conclusions.
✔️ Confirmation for key actions: Actions that change your browser, such as closing tabs or creating bookmark folders, require your confirmation first. Closed tabs can be restored with Undo.
✔️ Slash commands still supported: Commands such as /tabs and /bookmarks remain available as shortcuts.
2️⃣ Spaces: Project context in one place (New)
✔️ All materials together: Add web pages and tabs, uploaded files and images, Knowledge Base items and past conversations to the same Space.
✔️ Project notes: Add a description to a Space to record budgets, preferences and decisions already made. It is provided as context whenever you use that Space.
✔️ Reuse across conversations: Reference a Space with @ in the input box to use its materials in a new conversation. Once pinned, the Space is included with every follow-up question.
✔️ Create from a conversation: Choose “Save as Space” below a reply, or save the materials pinned in the input box directly as a Space.
✔️ Archive your results: Save files generated by tasks to a Space and continue working on them later.
✔️ Page reading preference: For each Space, choose whether to read the latest version of a page first or use the saved snapshot.
3️⃣ Understand pages and documents
✔️ Page Q&A: Answers are based on the actual content of the current page, not on the model's prior knowledge.
✔️ Multi-page comparison: Select several tabs or an entire tab group to compare prices, specifications and viewpoints side by side.
✔️ File and image Q&A: Upload PDF, Word or Excel files, or paste a screenshot, and ask about the content.
✔️ Video summaries: Reads YouTube and Bilibili subtitles to summarize videos and answer questions about them.
✔️ AI highlighting: Highlights key points directly in the original text, with an optional focus such as “pricing terms only”. You can also select text and add highlights from the context menu or with Alt+Shift+H. Highlights can be saved to the Knowledge Base together with the page link.
✔️ Web search: When the current page isn't enough, Starizon searches and reads public web pages and cites its sources.
✔️ Writing assistance: Summarize, extract key points, rewrite, proofread and compare alternatives.
✔️ Image generation: Create images from a text description (not available when using your own API key).
