## Connected Papers

The underlying problem Connected Papers tackles is that a literature review is usually conducted linearly: you find one paper, follow its citations, follow theirs, and gradually lose the thread of the wider field. Connected Papers instead computes similarity across a large scholarly corpus — building on data sources such as Semantic Scholar and Crossref — and lays the results out spatially. Papers that are frequently cited together or that share a large body of references cluster near each other, while the connecting edges show how strongly any two nodes relate. The layout is generated consistently, so the same graph is reproduced on later visits rather than reshuffling unpredictably.

The interface gives you two complementary views. The graph view is for orientation: which papers are central, which are recent, and which bridges connect separate clusters. The list view ranks related works by similarity and citation signals so you can drill into something specific. Common entry points include an arbitrary paper, a DOI, a URL, or a link to a conference proceedings. Prior Works and Derivative Works views are especially useful when you want to trace a field's ancestry or find what later built on a paper.

The service is aimed squarely at graduate students, postdocs and applied scientists who need to get up to speed on unfamiliar territory quickly — whether writing a related-work section, preparing a grant, or sanity-checking whether an idea has already been published. It is an independent research tool, not a publisher or a repository; the graphs are a discovery aid layered on top of existing scholarly metadata.

**Pricing & Plans:** Freemium

- **Similarity graph visualisation:** Each graph places the seed paper among its most closely related works, clustered by how often papers are cited together or share references.
- **Prior and derivative works views:** Separate perspectives show what a paper builds on and what later work builds on it, which is ideal for tracing a research lineage.
- **Multiple search inputs:** Start from a paper title, DOI, URL or proceedings link, so you can enter the graph from whatever you already have at hand.
- **Ranked list alongside the graph:** A ranked list view lets you browse related publications by relevance when you need specifics rather than an overview.
- **Stable, reproducible layouts:** The same graph is generated again on later visits, making it practical to bookmark a field's map and return to it while writing.

**Strengths:** Turns an otherwise linear citation chase into a spatial overview; Prior and derivative views make research lineage explicit; Works from a title, DOI or URL, so entry is frictionless; Free tier is enough to try it on real research tasks

**Limitations:** Requires JavaScript, so it cannot be read or scraped as a plain page; Graph quality depends on how well indexed the field is in the underlying corpus; Heaviest research-grade features sit behind paid plans

## Thunderbit

Thunderbit is an agentic web scraper built for teams that need data out of websites but do not want to maintain selectors or write scraping code. It installs as a Chrome or Edge extension: open any page, click extract, and the AI reads the layout and proposes the fields that make sense — product names, prices, emails, phone numbers, listings, reviews, and more. You confirm or refine the request in plain English, and the agent returns a clean table with the rows you asked for.

For high-volume sites it offers two faster paths. Pre-built templates cover popular destinations such as Amazon, eBay, Google Maps, Zillow-style listing sites, social platforms, and directories, returning the same fields every time without consuming AI credits. Agent mode handles less structured work by following links from list pages into detail pages, pairing each result card with the information on its article or listing so research tasks that would normally take hours finish in one run. AI can also summarize, categorize, translate, or reformat data during extraction, and results export to Google Sheets, Airtable, Notion, Excel, CSV, or through the Web Scraper API.

The product is positioned mainly for sales, real estate, operations, and marketing teams. Typical uses include scraping contact information and turning directories into lead lists, tracking buying signals like hiring or funding changes, aggregating property listings, monitoring competitor prices and SKUs, watching stock availability, and gathering reviews for sentiment analysis. Pricing is freemium: a free-forever tier with limited credits, then Starter, Professional, and Business plans that scale credits and add priority support, with an API and custom enterprise terms available.

**Pricing & Plans:** Freemium. A free-forever plan provides a limited monthly credit allowance, and paid Starter, Professional, and Business plans scale credits and features (yearly billing saves around 20% with credits upfront). A Web Scraper API is available for developer integration, and Business offers custom credits, custom limits, and priority support at custom pricing.

- **One-click AI extraction:** Open a page, click extract, and AI proposes the fields worth capturing and returns structured rows — no CSS selectors or drag-and-drop setup.
- **Pre-built site templates:** For popular sites like Amazon, eBay, and Google Maps, pre-built templates return consistent fields instantly without spending AI credits.
- **Agent mode with linked pages:** Thunderbit can open linked pages and pull details from them, so a results list and its detail pages become a single table in one run.
- **AI data shaping:** Summarize, categorize, translate, reformat, or calculate fields as part of the scrape, so exports arrive ready to use.
- **Direct exports and API:** Send results directly to Google Sheets, Airtable, or Notion, export to Excel or CSV, or connect via the Web Scraper API for developer workflows.

**Strengths:** Works without CSS selectors or coding knowledge; Pre-built templates for popular sites save AI credits; Agent mode follows linked pages for deeper enrichment; Exports directly to Sheets, Airtable, Notion, Excel, and CSV

**Limitations:** Fully free usage is limited by monthly AI credits; Scraping some sites can be affected by anti-bot measures or site terms; AI field suggestions occasionally need refinement for complex or unusual page layouts; Best experience requires the Chrome/Edge extension rather than a fully browser-free workflow
