## Kafkai

Kafkai originally launched as an AI article writer, but the product has since been rebuilt around a different idea: your AI is smart, but it has no live search data. Kafkai bridges that gap. It installs as an MCP plugin inside Claude, ChatGPT, Claude Code or a custom agent, so when you type a question like "which keywords does this site rank for?" your assistant calls Kafkai's tools and replies with real numbers — position, monthly search volume, link interssects and content gaps.

The workflow stays inside your existing AI. You ask, your assistant decides which Kafkai tools apply, Kafkai looks up and calculates the data, and your AI writes the answer in whatever form you want: a table, a list, a chart or a draft article. A one-time setup takes roughly half an hour. Beyond competitor research, Kafkai can push the article your AI wrote to your WordPress site as a draft, and for domains you have verified it also reads your own Search Console and analytics.

The method underneath is what Kafkai calls the 4C framework — Compete, Catch-up, Consolidate, Complement — which sorts a site's keyword gap against its competitors into four kinds of recommendation. Kafkai Giken has registered it with the Japan Patent Office as Patent No. 7701764. Pricing is prepaid rather than subscription: you buy credits and spend them per call, with new accounts receiving 1,000 free credits and no credit card required.

**Pricing & Plans:** Prepaid credit model with no subscription. New accounts get 1,000 free credits (valid 90 days, no credit card). Credit packs run from ¥1,100 for 1,000 credits up to ¥22,000 for 22,000 credits, with bonus credits (+5% and +10%) on the larger packs. Prices include Japanese consumption tax; 1 credit equals ¥1 before tax.

- **MCP plugin for your own AI:** Installs inside Claude, ChatGPT, Claude Code or a custom agent, so you keep asking questions in the assistant you already pay for and the answers come back with real data attached.
- **Real keyword and backlink data:** Returns the keywords a site ranks for with position and monthly search volume, plus link intersects showing sites that link to your competitors but not to you.
- **4C gap analysis:** Sorts the keyword gap between you and your competitors into Compete, Catch-up, Consolidate and Complement recommendations. Registered with the Japan Patent Office as Patent No. 7701764.
- **Your own Search Console and analytics:** Once you verify a domain, your AI can read your Search Console clicks and analytics data — numbers your competitors cannot see.
- **Research history and WordPress drafts:** Every research run is stored so you can ask what changed between runs, and Kafkai can send finished articles to your WordPress site as drafts for review.

**Strengths:** Answers come from real search data instead of the model's guesses, so both you and your competitors get different quality of output; No monthly subscription — you pay per question, so you can research a site once and read the results for weeks; Works inside the AI you already use, so there is no separate dashboard to learn; Domain verification unlocks your own Search Console and analytics data

**Limitations:** Setup as an MCP plugin takes around half an hour and is not for complete beginners; Prices are denominated in Japanese yen and include Japanese consumption tax; Credits expire after 90 days, so unused balance is lost; Kafkai deliberately does not write articles itself — you still need a separate writing tool or your own AI plan

## 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
