Key features	Selector-free extraction using computer vision and AI code generation Scheduled re-extraction that adapts automatically to page-layout changes Natural-language objective setting instead of scraping rules Automated interactions: opening sites, filling searches, following links Structured output filtering to match specific data criteria	Founded by former Cloudera and Hortonworks leadership Built on the acquired Robocorp Python automation engine Agent-first, reasoning-driven positioning versus legacy RPA Enterprise knowledge-work focus Python-based automation rather than UI-selector scripting
Pros	Selector-free design survives site redesigns that break rule-based scrapers Scheduled, recurring extraction removes the need to re-run jobs by hand Backed by a real pre-seed round and an accelerator vetting process, not a solo side project	Strong enterprise infrastructure pedigree among its founding team Python-based automation is more durable than UI-selector scraping Positioned clearly against the brittleness of legacy RPA approaches
Cons	No free tier, so teams cannot test real workloads before paying $99 a month Young company (2023) with a small public track record next to established scraping platforms AI-driven extraction can misread ambiguous page layouts and needs human spot-checking on critical data	No self-serve free tier or transparent pricing Very new company with a correspondingly short public track record Enterprise-only positioning excludes smaller teams
Company	Jsonify, founded 2023	Sema4.ai, founded 2024
