## Prepostseo

Prepostseo is a long-running web toolbox offering 150+ free online SEO utilities and AI writing assistants in one place. It bundles a plagiarism checker, paraphrasing tool, grammar checker, summarizer, AI essay writer, image-to-text OCR, humanizer, domain authority checker and dozens more, with paid Premium plans for heavier usage.

**料金とプラン:** 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.

**強み:** 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

**制約・デメリット:** 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

## Semflow

Semflow is an AI SEO assistant that works inside Webflow and Framer — and, via a Chrome extension, on any website. It audits every page, ranks issues by impact, tracks whether ChatGPT, Perplexity and Google AI are recommending you, and shows client-ready progress reports.

**料金とプラン:** Starter is $14/month (or $10/month billed annually), and Pro is $29/month (or $19/month billed annually). Every plan includes a 7-day free trial, unlimited sites and unlimited audits, and one subscription covers Webflow, Framer and the Chrome extension.

- **Audit and optimize in-builder:** Semflow checks every page of your site, ranks each issue by impact, and walks you through the fix inside your site builder so you always know where to start.
- **AI visibility tracker:** See whether ChatGPT, Perplexity, Gemini and Google's AI answers mention your site, find out what is holding you back, and track visibility as you improve.
- **Continuous monitoring and reports:** Automatic re-audits catch problems before your clients do, with rankings, site score and AI visibility tracked over time in one dashboard.
- **Chrome extension for any site:** A Chrome extension brings full site audits, keyword research and optimization guidance to any website on any platform, not just Webflow and Framer.
- **Client-ready reporting:** Client-ready PDF reports on the Pro plan show exactly what work was done and how results are trending.

**強み:** Fixes happen right inside Webflow and Framer — no context switching; Tracks AI answer-engine visibility alongside traditional rankings; Unlimited sites and audits on every plan; Chrome extension extends it to any platform

**制約・デメリット:** Optimization still requires judgment — it guides fixes rather than doing all SEO for you; Best value is for Webflow/Framer users; general-site users rely on the Chrome extension workflow; Keyword research and reporting are strong but not as deep as some enterprise SEO suites; Team seats and advanced reporting are gated to the Pro plan
