What is Sitegeist?
An AI assistant that lives in your browser. Built for collaboration, not autonomy theater. You guide, it executes. Automate repetitive web tasks, extract data from any website, and transform it into whatever you need.
Cookie ingredient calculator? Sure.

How about useful stuff?
Research People and Companies
Search Google, LinkedIn, news sites, and more. Sitegeist navigates multiple pages, extracts relevant information, and compiles everything into a living document with sources.
Extract Data to Spreadsheets
Scrape product listings, GitHub trending repos, search results—anything visible on a webpage. Export to Google Sheets with formatting, download as CSV, Excel, PDF, Word, or JSON, or create an interactive visualization.
Fix Your Grammar and LinkedIn Game
Catch typos and grammar mistakes in emails, social media posts, or anywhere on the web. Polish your LinkedIn posts before publishing. Works in real-time on any editable text.
Summarize Videos, Ask Questions
Extract YouTube transcripts with timestamps, break videos into beats with summaries, or get executive summaries. Ask questions about what's currently shown. Works with any YouTube video.
Automate Social Media Engagement
Check your LinkedIn posts for unanswered comments and get AI-generated reply suggestions. Analyze WhatsApp conversations. All without leaving your browser.
Turn Messages Into Calendar Events
Read direct messages from Bluesky, WhatsApp, or anywhere else. Extract meeting details like date, time, and location. Create Google Calendar events automatically—all without copy-pasting.
Your turn.

The good, the bad, and the 'I can't believe it did that'
It works much better than anything I used before. Amazing job.
ChatGPT Atlas definitely does not feel great, but I watched @badlogicgames's sitegeist and it looks pretty damn cool when it fucks around with the browser. Much better.
Sitegeist is soooo cool! I'm so happy I could get away from Comet.
trying my hardest to crash chrome
ok, damn nice. perplexity comet browser failed after 10 tries. Sitegeist got it first try.
This onboarding is incredible. Even the hiccups it ran into it's been fantastic about trying something else. This is so cool! Plus now I have multiple cookie recipes :) thanks! Will report the bugs I find.
We Don't Want Your Data
Use Your Browser
Works in Chrome, Edge, Brave, and other Chromium-based browsers. No custom browser required, no data mining.
Your Choice of AI
Use OpenAI, Anthropic, Google, OpenRouter, Groq, Cerebras, xAI, Z.ai, or self-hosted and local models via Ollama, LM Studio, llama.cpp, vLLM, SGLM.
Privacy First
Your settings, API keys, and chat history stay on your computer. Only your messages go to your chosen AI provider—configured to not retain or train on your data.
Your Data, Your Control
Export your entire chat history and settings at any time. Import them anywhere. No lock-in, no vendor control.
Track per session and overall cost across models and providers
Skills, Artifacts, and Attachments
Skills
Teach Sitegeist how to interact with any website once, save it as a "skill," and reuse it forever. Skills are site-specific automation libraries that load automatically when you visit matching domains.
Example: Create a skill for your favorite store's search and product extraction. Next time you visit, Sitegeist already knows how to navigate and scrape.
Artifacts
Living documents that persist throughout your session. Create markdown notes, interactive HTML dashboards, images, PDFs, or Excel files. Update them as you work, and download when done.
Example: Start a research note when investigating a topic. As Sitegeist navigates and extracts data, it continuously updates your note with findings and sources.
Attachments
Drop files right into the chat. PDFs, Office documents, images—Sitegeist reads them all. Ask questions about uploaded files, extract data, or combine information across multiple documents.
Pricing
Fair pricing for software. At-cost billing for AI. We're not token merchants.

FAQ
Yes. You'll sign up with sitegeist.ai for license enforcement. We only store your payment info and license information—nothing else.
Desktop Chromium browsers: Chrome, Edge, Brave, and others. Firefox support is coming soon—we're waiting for them to implement required browser features.
Yes. Any OpenAI Chat Completions or Responses compatible endpoint works—Ollama, LM Studio, llama.cpp, vLLM, SGLM, and more.
Everything stays on your computer—settings, API keys, and chat history. Only your messages go to your chosen AI provider. Sitegeist configures providers to not retain or train on your data when supported. Some authentication methods (like Anthropic's Claude Pro/Max OAuth tokens) can't be used directly from the browser due to CORS restrictions. In this case, requests need a proxy. You can use your own, a trusted provider like corsproxy.io, or our default proxy which forwards requests without logging or storing any data. Sitegeist checks in with sitegeist.ai for license verification (your email and subscription status only). We collect zero telemetry and never will.
No, Sitegeist is source available. As a Chrome extension, we must package all code in non-obfuscated form for Web Store reviewers. This means you (or a technical friend) can dissect it too. While Sitegeist is unlikely to become truly open-source, we ensure the sources we ship make it easy to review what Sitegeist is doing. You can also observe any and all network requests it performs.
Malicious websites can hide instructions that trick the AI into taking unwanted actions—like accessing your logged-in accounts. The technical term is prompt injection, and all browser AI assistants face this challenge. Sitegeist implements mitigations, but no system is perfect—we believe transparency matters more than false promises. For safety, use Sitegeist in a separate Chrome profile where you're not logged into sensitive accounts.
