## Lection

Lection is built around a simple idea: instead of mapping CSS selectors or writing scraping scripts, you tell the tool in plain language what data you want from a page, and an AI agent figures out how to collect it. The Chrome extension handles interactive, one-off extractions, while the cloud component runs the same scrapes on a schedule so your data stays current without you keeping a tab open.

The product is designed for end-to-end data workflows rather than just pulling a table once. It follows pagination, infinite scroll, and detail links, then joins listing data with detail-page data into a single table. From there you can export to CSV, Excel, or JSON, or push rows directly into Google Sheets, Airtable, Notion, Supabase, and automation platforms like Zapier, Make, n8n, Pipedream, and custom webhooks, with Slack, Discord, and Microsoft Teams notifications for finished runs.

Lection ships with a library of prebuilt templates for common jobs, including Instagram posts and followers export, Twitter (X) followers export, GitHub contributors, LinkedIn connections, YouTube search results, and Google Maps business search. It is widely used for sales prospecting, market research, and operations data collection, and the site also publishes comparisons against alternatives such as Browse AI, Web Scraper.io, and Octoparse.

**Pricing & Plans:** Lection offers a free path to get started via the Chrome extension, with paid tiered plans for cloud runs, scheduling, and higher volume. Exact plan limits and prices are listed on the Lection pricing page.

- **Natural-language scraping:** Describe the fields you want in plain language and Lection's AI determines how to extract them, no selector configuration needed.
- **Chrome extension plus cloud runs:** Scrape interactively in your browser, or schedule scrapes to run in the cloud even when your browser is closed.
- **Pagination, scroll, and linked pages:** Follow pagination and infinite scroll, then combine listing pages with detail pages into one unified table.
- **Direct integrations and exports:** Export CSV, Excel, or JSON, or send rows straight to Google Sheets, Airtable, Notion, Supabase, Zapier, Make, n8n, Pipedream, or a custom webhook.
- **Ready-made scraper templates:** Start from prebuilt templates for Instagram, X/Twitter, GitHub, LinkedIn, YouTube, Google Maps, and marketplaces like Amazon and Walmart.

**Strengths:** Plain-language setup removes the need to write or maintain scraping code.; Chrome extension and scheduled cloud runs cover both one-off and recurring jobs.; Broad integration list, from spreadsheets and databases to Zapier, Make, n8n, and webhooks.; Library of ready-made templates and guides speeds up common scraping tasks.

**Limitations:** Some sites with aggressive anti-bot protection may still block automated extraction.; Cloud scheduling and higher volumes require a paid plan.; Advanced custom logic may feel constrained compared with fully code-based scrapers.

## Sider

Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight.

Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel.

Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base.

**Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans.

- **AI sidebar on any page:** 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 and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material.
- **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move.
- **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions.
- **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits.

**Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks

**Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans
