Features

Every tool, deeply crafted.

Twelve months of iteration across 21 files. Each capability tested against real sites, real edge cases, real users.

01

Structured data extraction

Fire CSS-selector or smart extraction at any page. Pick fields by name and Benzo maps them to the right attribute automatically — href pulls URLs, text pulls readable text, alt pulls alt text.

  • :scope container mapping
  • Auto-detected repeating cards
  • Table → headers → rows inference
  • List <ul> and <ol> fallbacks
02

Full-page screenshots

Uses Chrome DevTools Protocol to resize the viewport to the entire page height, then captures once. No stitching, no repeated headers, no black bands.

  • Background lock during capture
  • Lazy-load sweep before capture
  • Dark and light page support
  • Automatic cleanup
03

Screen recording studio

A full recording workspace in a dedicated tab. Choose quality, bitrate, and format. Mix your mic with tab audio. Pause and resume any time.

  • WebM VP9/VP8 or MP4 H.264
  • Mic + system audio mixing
  • Auto-download when stopped
  • Session list with per-clip actions
04

Three-layer unlock

Right-click, selection, copy, and paste restored on any site. Bypasses inline handlers, CSS user-select:none, overlay traps, and even pages that re-register blockers in JavaScript.

  • MAIN-world event guard
  • Attribute and style stripping
  • Capture-phase stopPropagation
  • Overlay detection and disable
05

Agent engine

A ReAct loop that reads the DOM, plans one action at a time, executes, and reflects. Local rule-based planner by default. Optional LLM planner via your own proxy.

  • Snapshot → Plan → Execute → Repeat
  • Element highlighting during actions
  • Approval gate for risky actions
  • Saved runs replayable with one click
06

Human-in-the-loop

Three approval modes: off, guarded (pause only on risky actions like buy/delete/submit), and paranoid (approve every action). You decide how much control to hand over.

  • Heuristic risk detection
  • LLM-declared risk support
  • Approve or reject any step
  • Reject resumes to next step
