AI sidebar and browser agent for reading, writing and research
A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab.
Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.

Record your browser work once, and let Spion turn it into an automation that runs without you.
One click starts capturing your actions across tabs, forms and dashboards, with zero configuration and no script to write.
Spion scans the recorded steps, identifies the repeating pattern, and rebuilds it as an optimised workflow with a proper trigger rather than replaying every click.
Finished workflows drop into n8n, Make, Zapier, Workato or Claude as importable files, recipes or prompts, so you keep using the tools you already trust.
Spion also generates an editable, enablement-grade PDF or SOP so colleagues can follow a documented process rather than guess.
