- Starizon is an AI agent in Chrome's side panel. Ask it to compare the products in your tabs, find an article you bookmarked, turn page data into a sheet, or make a plan from the research you saved.
You can combine those steps in one request. For example, ask it to open this week's bookmarked articles, highlight the key points, and save them to your Knowledge Base. Connect an app when you want the result in a Gmail draft, a document or a spreadsheet.
Choose Agent S6 for tasks that need clicks and typing on websites. Replay, schedules and page monitors have their own setup. Scheduled runs and monitors need Chrome to be running. - You can work with the pages, tabs and bookmarks in your browser, then carry the result into the next step. Ask for a comparison, organize the source tabs, and save the notes in the same conversation. Agent S6 adds browser actions in the websites you are signed into.
Your Knowledge Base gives you a place to keep pages, highlighted passages and files on your device. Bring that saved material into a new task, with references to the copy you kept. - Choose Agent S6 in the panel when your task needs browser actions. It opens pages, clicks controls and fills fields using the information you provide, in the browser you already use. Those actions can be part of a larger request involving research, saved material or connected apps.
Follow the progress in the panel and respond when it needs your input or confirmation. Supported browser runs can be saved as Replay. A whole conversation that combines tabs, knowledge and connected apps does not become a Replay. - Save whole pages, highlighted passages and files into a library on your device. You can bring in open tabs, bookmarked pages or a list of links, then organize the material into collections. Pages you can read while signed in can be saved too.
Ask about your saved material, or use it in a comparison, a plan or a draft alongside information from the web. The agent can also save useful results back to your library. Use @ to select a particular collection.
Saved text and the search index stay on your device. When you ask a hosted model to work with that material, the relevant content is sent with your request. References point to the copy you saved. - Starizon is local-first. The extension stores these materials in your browser profile:
- Your conversations. Chat history lives in the browser. The Starizon website cannot display it.
- Your configuration. Agent and Replay setups, skills, schedules, monitors, and the screenshots monitors keep.
- Your Knowledge Base. Saved pages, highlighted passages, files, and the search index that makes them findable. Search runs on your device.
- Your Spaces. Project materials and saved conversations for use in later chats.
AI requests send your prompt and task context to the model service you use. That context can include page text, saved excerpts, conversation content, files or screenshots. With your own API key, model requests go from the extension to your configured provider. Web search, connected apps and notification services receive the inputs needed for their actions.
Starizon uses servers for account, entitlement, billing and credit records. Check the model and connected-service providers' policies for their retention and training practices. The Data Policy goes feature by feature through what each one reads, what stays local, and what is sent. - Every account gets 200,000 one-time credits at sign-up, whatever the plan. Free includes the core product, daily and monthly AI usage limits, 2 active schedules, and 2 active page monitors.
Basic, Pro, and Lifetime include the same feature access. They remove the daily and monthly local caps on Agent S6 steps, scheduled AI steps, Replay runs, Knowledge Base questions, AI highlights and tab organization, and allow up to 20 active schedules and monitors in total. The difference is hosted AI credits and billing:- Basic: 3,600,000 credits each month. $5 monthly or $55 yearly.
- Pro: 12,000,000 credits each month. $15 monthly or $165 yearly.
- Lifetime: 5,000,000 one-time credits for a $49 one-time payment. It has no monthly credit refill.
- Starizon deducts credits when you use hosted AI models or Starizon services such as built-in web search, app actions and email alerts. For hosted AI, usage depends on the model and the amount of input and output. Other services charge per use, such as each search or each email sent.
Basic and Pro credits reset on the first day of each monthly credit cycle and unused monthly credits do not roll over. Sign-up credits, Lifetime credits and any top-ups you buy stay until you use them.
With BYOK, your model provider bills the model request. Starizon cloud services used by the task still consume Starizon credits. - No. Chrome must be running. If Chrome was closed or asleep, reopening it within the recovery window lets Starizon run at most one eligible catch-up. It does not replay every missed run.
Free supports up to 2 active schedules and 2 active monitors, counted separately. Basic, Pro, and Lifetime support up to 20 active schedules and monitors in total.
On Free, a repeating reminder can run every minute. Repeating tasks that run without AI need at least 15 minutes between runs, and AI or Agent tasks need at least 30. One-time tasks are not affected, and paid plans allow shorter intervals. - Installing the extension and opening the panel need nothing. Sending your first message needs one of two things: a free Starizon account, which comes with credits to start, or your own model API key, which sends model requests straight to your provider.
Your own key pays for model requests. Starizon services such as built-in web search, app actions and email alerts still need an account and credits. - Yes. Add a key for OpenAI, Gemini, Anthropic, xAI Grok, or an OpenAI-compatible endpoint in Settings. Model requests go directly from the extension to the provider you choose.
BYOK does not remove the Free plan's daily and monthly local usage limits. It also does not cover Starizon services such as built-in web search, app actions or email alerts, which still use Starizon credits. - Starizon works inside the browser window you already have open, using the session your browser already holds. It does not handle your passwords: when a page needs you to sign in, it stops and hands the keyboard back to you.
Starizon stores your chat history, Knowledge Base and Spaces in your browser profile. AI requests send your prompt and task context to the model service you use, including page screenshots when browser actions need them. With your own API key, model requests go to your configured provider.
It stops for four things: a confirmation, something only you can type, a choice between options, and a page it cannot get past on its own. A task left running while you are away pauses at those same points and waits until you come back.
Tools that write or delete are off until you turn them on, one at a time, and a step that touches a connected app is labelled as writing to an external system before it runs. Anything you cannot undo, such as submitting or paying, waits for your decision. - Ask about the page in front of you, several open tabs at once, a PDF, Word, or Excel file you drop into the panel, a screenshot, or a video page when subtitles are available.
Type @ to point a question at specific tabs or at a Knowledge Base collection. Alt + Shift + P summarizes whatever is on screen without opening the panel first, and Alt + Shift + V starts voice input. - Extraction turns repeated page content into rows, such as product prices, job listings or table data. Name the columns you need, then use the result for a comparison or send it to a connected spreadsheet.
You can include extraction in a larger request. The /extract shortcut is also available when you want to start with page data. - Replay saves supported browser runs and extraction actions for you to run again. You can edit supported workflow steps or schedule a saved Agent workflow. Extraction replays do not currently run on a schedule, and a whole combined conversation cannot be saved as one Replay.
A Skill supplies reusable instructions, such as your preferred writing style or a method you use often. You can add Skills to guide the agent. A saved Replay can also have a shortcut that you choose to run. - A schedule can send a reminder, run Agent S6 browser automation or run a supported browser Replay at a chosen time. A monitor checks a page on a schedule and alerts you when its condition matches. In AI Chat, choose /schedule or /monitor and describe what you want. Review the generated settings before saving.
Browser notifications are the default. You can also enable email, webhook, or ntfy phone push delivery in the task editor. - Yes. Use AI judgment when the condition needs page context, such as "alert me if the refund policy becomes less favorable" or "alert me when this update affects API users." Use keyword, numeric, percentage, or regular-expression checks when the condition is exact.
You can also set how many checks in a row have to agree before it alerts you, and how many before it resets, so a value sitting on your threshold stops bouncing. When the thing you are watching sits behind a login or a filter, browser automation can repeat those steps before each check. AI judgment uses a model and may consume credits based on the content it evaluates. - Ask Starizon to highlight the parts you need, or use /highlight. It marks passages on the article itself. You can review and remove the marks, then ask it to save the useful passages to your Knowledge Base as part of the same task.
You can also highlight passages yourself from the right-click menu or keyboard shortcut. Manual highlighting uses no model and is not metered. - Yes. Ask it to group tabs by topic, find duplicates or bookmark the articles you want to read later. Combine those requests with reading and comparing the pages. The /tabs shortcut is available too.
Review the tabs marked for closing before they close. If you need one again, you can reopen it. - Find Chrome bookmarks by topic, title, folder or the date you bookmarked them. Ask Starizon to open the matches, read the pages, save new bookmarks or move existing bookmarks to a folder you name. It can create a destination folder when needed. Review the reported changes after the task.
Bookmark search uses bookmark details rather than the full text of every linked page. Your bookmarks remain in Chrome. Details needed for an AI task may be included in the model request. Save pages to your Knowledge Base when you want to search their content later. - Toolkits, shown under Apps in the current extension, connect services such as Gmail, Notion, Google Sheets, Google Docs, and Airtable. MCP Sources add tools from a compatible remote MCP server.
Connections are opt-in. Authorize only the accounts and tools you need. Starizon supports remote MCP connections; local stdio MCP servers are not supported. - The supported public release is available through the Chrome Web Store for Google Chrome 120 or newer. Other browsers are not officially supported at this time. Some Chromium browsers can install Chrome Web Store extensions, but Starizon does not currently test or guarantee those installations.
The interface is fully translated into nine languages: English, 简体中文, Deutsch, Español, Español (Latinoamérica), Français, 日本語, 한국어, and Português (Brasil). - You can cancel a subscription from the . Cancellation stops the next renewal; paid access continues through the current term.
