Pluno Browser Agent

Pluno Browser is a Chrome extension that lets users describe outcomes in plain language and then executes those tasks by talking directly to web app APIs — bypassing the need to click through user interfaces. The product is positioned as a faster alternative to browser-based AI agents like Claude's browser extension, and is built by Pluno AI, a company founded in 2021 by two AI engineers who previously built a support automation prototype called AwesomeQA.

What It Is

Pluno Browser is an AI-powered browser extension that acts as a personal operator across SaaS tools. Rather than automating UI interactions element by element, it communicates with each web app's underlying API, which the company claims makes it faster and more resilient to UI changes. Users install it from the Chrome Web Store, open it as a widget or sidebar on any web app, and type natural-language instructions to get tasks done.

How the API-First Approach Works

The core differentiator Pluno highlights is that it bypasses the browser UI entirely and routes actions through each tool's API. This means:

• Configuration changes (e.g., muting notifications after 7pm) happen without navigating settings menus
• Bulk actions (e.g., reassigning 200 HubSpot contacts) run programmatically rather than through repeated clicks
• Data exports, cleanups, and reporting tasks execute in seconds rather than minutes
• The extension includes self-learning so it improves task completion speed with each interaction

The product page states it has "deep knowledge on more than 50,000 tools" and can learn any new tool shown to it in seconds.

Benchmark Claims

Pluno publishes a vendor-produced benchmark comparing task success rates across browser agents. According to the company, Pluno achieved a 90.4% task success rate measured across 312 real-world tasks in 24 tools (including HubSpot, Notion, Stripe, and Linear) in July 2026. The company claims this outperforms Notte (77.2%), Browser Use with Opus 4.8 (73.5%), Stagehand + Browserbase (69.1%), Skyvern (63.8%), Perplexity Comet (57.6%), Claude extension (56.1%), and ChatGPT Atlas (54.4%). These figures are vendor-published and have not been independently verified.

Target Audience

The product page identifies three primary user groups:

• Ops & RevOps teams who work across HubSpot, Salesforce, and multiple other tools
• Founders and managers who need to operate software without deep product expertise
• Anyone buried in SaaS who prefers describing outcomes over hunting through settings

Security and Compliance

Pluno Browser includes several security controls the company highlights:

• User approval required before any action is executed
• No model training on user data
• Sensitive data and credentials are stripped before being passed to any LLM
• GDPR compliant by design
• SOC 2 Type II certified (independently audited)
• Extension can be paused per-site or removed entirely in one click

Supported Tools and Setup

The extension works on Chrome, Edge, and other Chromium-based browsers (Brave, Arc). Setup involves a single install from the Chrome Web Store with no configuration required. The product page lists integrations with Gmail, Notion, Linear, Jira, HubSpot, Dropbox, Google Calendar, Stripe, Shopify, Figma, Asana, GitHub, Zendesk, Airtable, Intercom, and Trello, among others.
