## Prepostseo

Prepostseo is one of the older and broader free toolboxes on the web, and it has grown into a directory of more than 150 utilities aimed at webmasters, students, teachers and SEO specialists. Its bread and butter is text: a plagiarism checker, paraphrasing tool, grammar checker, summarizer, article rewriter and a growing family of AI generators for essays, emails, stories, slogans and cover letters.

Alongside the writing tools sits a deep SEO and website-management section — domain authority and age checkers, keyword density, backlink maker, sitemap generator, DNS and IP lookup utilities, minifiers, encoders and more. There is also a practical file-handling corner: image-to-text OCR, PDF and Word converters, barcode and QR scanners. Everything runs in the browser without installing software.

The service follows a freemium model. Most tools are usable for free with no account, which is why it attracts millions of visits each month, while a Premium plan raises limits and unlocks more detailed reports and heavier AI usage. Because the site mixes free, ad-supported pages with paid features, the experience is functional rather than polished, but the breadth of tools in one place is hard to match.

**Pricing & Plans:** Freemium. The majority of the 150+ tools — including the plagiarism checker, paraphraser, grammar checker, summarizer and image-to-text — are free to use. A Premium subscription adds higher usage limits and advanced features.

- **Plagiarism checker:** Compare your writing against billions of indexed sources to catch copied or unoriginal passages before publication.
- **Paraphrasing tool:** Rewrite sentences in multiple modes to improve flow and avoid repetition while keeping the original meaning.
- **Grammar, summarizer and readability:** Fix spelling, punctuation and tense errors in one click, with summaries and readability scores to tighten long drafts.
- **Image to text and file conversion:** Extract editable text from images and scanned documents, and convert between formats like PDF, Word and Excel.
- **SEO and domain utilities:** Check domain authority, keyword density, backlinks, page speed signals and more for fast on-page audits.

**Strengths:** Very large selection of SEO and writing tools in one place; Core tools like the plagiarism checker and paraphraser are free; No installation needed — everything runs in the browser; Covers text, SEO, file conversion and OCR in one site

**Limitations:** Ad-heavy pages and upsells can make the interface feel cluttered; Best results on plagiarism and AI-detection often sit behind the paid Premium tier; With 150+ tools the navigation and quality vary between individual utilities; Free limits on longer documents and advanced modes

## 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
