🧰 Who is this useful for:

• Business owners automating repetitive research tasks
• Social media managers streamlining content workflows
• Researchers gathering data from multiple websites
• Marketing teams automating competitive analysis

STEP 1: Install and Configure Nanobrowser

Head to the Chrome Web Store and search for "Nanobrowser" or use this direct link, The project is open source and their GitHub repository has over 6k stars.

Once installed, click on the Nanobrowser icon in your extensions menu, then click the settings icon. Navigate to the “Models” section and add a new provider. Choose Gemini as your preferred AI model.

To get your API key, visit Google AI Studio and click "Get API Key." If you don't have one, create a new API key and paste it into Nanobrowser's settings.

STEP 2: Optimize Your Model Settings

For optimal performance, configure your models as follows:

• Model Selection: Choose Gemini 2.5 Pro for the main model
• Planner: Set to Gemini 2.5 Pro for complex task planning
• Validator: Use Gemini 2.5 Pro for result validation
• Navigator: Gemini Flash works perfectly for navigation tasks

These settings ensure the best balance between performance and cost-effectiveness for your automation tasks.

Note: The Gemini 2.5 Pro model might not be available for free users.

STEP 3: Execute Your First Automation Task

Open Nanobrowser's sidebar and try a simple research task to understand how the system works. For example, type: "Find the latest releases by OpenAI and summarize the key features."

Watch as the AI automatically:

• Navigates to OpenAI's website or relevant news sources
• Searches for recent announcements and releases
• Filters through release notes and documentation
• Scrolls through pages to gather complete information
• Validates the results before presenting them

The entire process happens without any manual intervention on your part.

STEP 4: Advanced Social Media Automation

Since Nanobrowser uses your existing browser sessions, you can automate tasks on platforms where you're already logged in. Try more complex tasks like: "Find industry leaders on LinkedIn and save their profiles to a list"

The extension can handle multi-step processes, form filling, and even interaction with dynamic content. It's particularly powerful for tasks that would normally require multiple browser tabs and extensive manual clicking.

Pro tip: Start with simple tasks to understand the AI's capabilities, then gradually increase complexity.
