WebBrain vs Yasmine: Features, Pricing & Which Is Better (2026)

A side-by-side comparison of WebBrain and Yasmine — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.

WebBrain

Emre Sokullu

Free

Free, open-source browser AI agent for Chrome, Firefox, and Edge that reads pages, extracts data, and automates tasks with any LLM.

Page Understanding: Reads and comprehends any web page, PDF, article, doc, or dashboard and answers questions from the current page content on the spot.
Full Browser Agent: Clicks, types, scrolls, navigates, and interacts with pages on your behalf to automate repetitive tasks from natural-language instructions.
Read-Only Ask Mode by Default: Starts safe — asks before any consequential action, with stricter rules for sensitive fields, to defend against hijacked pages.
Multi-Provider LLM: Works with local llama.cpp, OpenAI, Anthropic Claude, and OpenRouter so you can pick the model or run fully offline.
Dedicated Vision Model: Pairs a fast text-only planning model with a separate vision-capable model for screenshots — cheaper and faster than a single multimodal model.
Data Extraction: Pulls structured data (tables, lists, links, form contents) out of any page and can export product catalogs, search results, or PDF content.
Smart Context Management: Automatically trims conversation history and limits tool output to prevent token overflow during long sessions.
Optional Profile Auto-fill: Local plaintext bio (name, work email, company, throwaway password) lets the agent breeze through low-stakes signup forms; off by default, stored locally.

Research Summaries: Open a long article, doc, or PDF and ask WebBrain to summarize or answer specific questions grounded in that page.
Form Auto-fill: Have the agent complete government, tax, or signup forms by recalling saved profile fields — then review before submit.
Web Scraping Without Code: Extract product catalogs, price lists, or search results from any page into a clean structured list.
Offline / Private Browsing AI: Run entirely on-device with llama.cpp to keep sensitive pages, credentials, or client data off the cloud.
Dev Workflow Assist: Inspect a localhost preview, propose CSS or code changes, and iterate on your own site from the sidebar.
Video / File Downloads: Locate and save streaming media or attachments from a page you're viewing.
Self-Hosted Corporate AI Browser: IT teams deploy WebBrain to give employees a browser agent that never sends data to a third-party vendor.
