## Do Browser

Do Browser is a Chrome extension that turns natural-language requests into real browser actions. Instead of writing scripts or recording macros, you describe the outcome, for example a page you want scraped or a form you want completed, and the agent works through the steps itself: opening pages, locating buttons, entering text and reading on-screen content the way a person would. It advertises support for any website, spanning shopping sites, social platforms and internal business tools.

Beyond clicking and typing, Do Browser can generate and run code in the background to scrape or automate more efficiently, work across multiple browser tabs at once, and deliver collected information as downloadable CSV files or spreadsheets. Typical uses include web scraping, price comparison, drafting social posts, capturing screenshots and working through complicated web interfaces.

The extension uses a subscription model at $25 per month with a 7-day free trial, and it also offers a bring-your-own-key route where you can use your own Gemini API key or Claude subscription at no extra cost. It is published by the team behind dobrowser.io and is aimed at people who want automation but do not want to code.

**Pricing & Plans:** $25/month with a 7-day free trial, cancel anytime. A free option is available if you bring your own Gemini API key or Claude subscription.

- **Natural-language commands:** Describe the task in ordinary sentences and the agent figures out the clicks, typing and navigation needed.
- **Visual page understanding:** The AI interprets pages much like a person does, finding buttons and following flows even on unfamiliar layouts.
- **Data export:** Download the information it gathers as CSV files and spreadsheets ready for further analysis.
- **Background code generation:** Writes and runs code behind the scenes to scrape or automate tasks more efficiently.
- **Multi-tab support:** Works across several browser tabs at the same time for broader tasks.

**Strengths:** No coding required to automate tasks; Works on virtually any website; Exports collected data to CSV and spreadsheets; Free option via your own Gemini key or Claude subscription

**Limitations:** Full subscription costs $25 per month; Rating sits around 3.3 out of 5 from user reviews; Requires granting the extension broad browser access

## Sigma AI Browser

Sigma AI Browser is an AI-first browser built on the Chromium engine and wrapped in privacy features. Its centerpiece is an in-browser AI agent that interacts with websites like a real user — clicking buttons, filling fields, submitting forms, and gathering data — so tasks such as booking, inbox cleanup, bill payment, or spreadsheet updates can be delegated rather than done by hand. Alongside the agent, Sigma AI Chat handles questions, research, text creation, and image generation in one place, while Deep Research mode queues sources, clusters information, and produces structured insights for market or academic work.

A distinguishing feature is Eclipse, a local LLM built directly into the browser. Because prompts are processed on your device, sensitive information stays local, responses are faster, and there is no reliance on cloud processing for everyday questions, summaries, or writing. Privacy extends to the rest of the product: TLS 1.3, HTTPS, and DNS-over-HTTPS secure connections, a built-in ad blocker reduces noise, phishing sites are flagged in real time, and user data and AI chat conversations are end-to-end encrypted. A mnemonic profile gives the browser identity a cryptographic foundation with a 12-word recovery phrase, and private profiles separate work, personal, and account spaces.

Because it is Chromium-based, Sigma keeps the familiar tooling — bookmarks, password managers, history, and support for Chrome-style extensions — with a simpler interface. It adds Web3 integration so wallets and decentralized apps work directly in the browser, plus translate-on-page and chat-with-page conveniences. The browser is available for macOS, Windows, and iPhone, with an Android waitlist and a Linux version announced as coming.

**Pricing & Plans:** Sigma AI Browser is offered as a free download through its website and the App Store; there is a pricing page on the site for plan-related details. Confirm current terms on the official site.

- **Agentic browsing:** Describe a goal and the built-in agent navigates pages, fills forms, and completes multi-step tasks for you.
- **Local AI with Eclipse:** An on-device LLM processes prompts locally, so sensitive data never has to leave your machine.
- **Deep research and chat with page:** Queue sources, cluster information into structured insights, and turn any site into a conversation for instant summaries.
- **Privacy and Web3 built in:** TLS 1.3, DNS-over-HTTPS, ad blocking, phishing warnings, mnemonic profiles, and direct wallet or dapp access.
- **Lean performance:** Independent Speedometer 3.0 testing and memory comparisons position Sigma as lighter and faster than common browsers.

**Strengths:** Free to download with a built-in agent, chat, and local LLM; Local Eclipse model keeps prompts and sensitive data on the device; Chromium base means extensions, bookmarks, and password managers still work; Privacy stack covers ad blocking, DNS-over-HTTPS, phishing detection, and encrypted chat

**Limitations:** Linux and Android versions are not generally available yet; The agentic and local-AI features require a recent, reasonably powerful device for best results
