## LightFill

LightFill targets a very specific annoyance: you have the document and you have the form, and the only thing in the way is re-typing data that already exists. The extension is designed to close that gap. Instead of copying a passport number or an invoice total across by hand and hoping you did not transpose two digits, you let the extension extract the values with AI-based document processing and fill the form for you in one action.

Its developer describes support for a range of document and form types — identity papers, passports and invoices are the examples given — with the goal of working across the many layouts administrative and purchasing forms come in. Because the extension touches identity documents, the listing emphasises security protocols for protecting personal data, and the developer's disclosure notes that it handles personally identifiable information, financial and payment information, authentication information and website content, while stating the data is not sold to third parties.

It is a small, single-purpose tool rather than a suite: published by an independent developer based in France, listed under Tools, and last updated in 2024. The extension itself is free to install and the store listing notes that it offers in-app purchases. If your work involves paperwork — visa and onboarding forms, expense claims, invoice entry — it is aimed squarely at how much of that day disappears into typing.

**Pricing & Plans:** Free to install from the Chrome Web Store; the listing notes that the extension offers in-app purchases. No standalone public pricing page is published.

- **AI document extraction:** Reads structured values out of ID cards, passports, invoices and other documents instead of asking you to type them.
- **One-click form filling:** Maps extracted values into the fields of the web form you are looking at, so a completed form is one action away.
- **Broad document and form coverage:** Built to handle multiple document layouts and the varied field arrangements of administrative and checkout forms.
- **Time saved on repetitive entry:** Removes the slow, mistake-prone copy-typing that dominates routine paperwork and online purchasing.
- **Security-focused handling:** The developer highlights protection of personal data and discloses which categories of information the extension processes.

**Strengths:** Removes a genuinely tedious, error-prone task with a single click; Handles several practical document types, including ID cards, passports and invoices; Free to install, with the option of in-app purchases as needed; Open about what data categories it processes and states data is not sold to third parties

**Limitations:** Available only as a Chrome extension, so other browsers are not covered; Handling identity and payment documents makes reading its privacy disclosure essential before use; A small independent tool with a limited public track record and no standalone product site

## 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
