AI web scraper that turns any website into structured data
Describe the fields you want in plain language and Lection's AI determines how to extract them, no selector configuration needed.
Scrape interactively in your browser, or schedule scrapes to run in the cloud even when your browser is closed.
Follow pagination and infinite scroll, then combine listing pages with detail pages into one unified table.
Export CSV, Excel, or JSON, or send rows straight to Google Sheets, Airtable, Notion, Supabase, Zapier, Make, n8n, Pipedream, or a custom webhook.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.
