Are these SEO and text tools free?

Yes. Every tool on this page is free, no sign-up, no rate limits, and runs client-side in your browser wherever possible.

Do the grammar / spell checkers need an account?

No. They call the public LanguageTool API directly from your browser — no API key or login required.

How accurate is the plagiarism / AI content detector?

The plagiarism checker generates verified Google search links for each sentence so you can check the web manually. The AI content detector uses heuristics (sentence burstiness, AI-phrase density, vocabulary variance). Neither is a replacement for paid services like Copyscape or GPTZero.

Does the OCR / image-to-text work on handwriting?

OCR is powered by Tesseract.js and works best on printed text. Handwriting is supported but with lower accuracy.

Is anything uploaded to a server?

No. All processing happens in your browser or goes directly to the relevant public API (LanguageTool, MyMemory). Nothing is stored by this site.

How the toolkit works

Everything you need in one page

Count, rewrite, check, translate — all in your browser

This page bundles 46 free text and SEO utilities that I personally use while writing blog posts, optimising meta descriptions, cleaning up client content and debugging copy-paste issues. Nothing here gets sent to a private server — the tools either run purely with JavaScript or call well-known public APIs (LanguageTool for grammar, MyMemory for translation, Tesseract.js for OCR).

Use the Count & Analyze tab to check word count and reading time, jump to Grammar & Proofreading for spell/grammar/punctuation fixes, or head to the Rewriters tab to paraphrase an article. Fancy Text converts normal text into 𝐁𝐨𝐥𝐝, ᴍᴀʟʟ ᴄᴀᴘs, ⁿᵒʳᵐᵃˡ superscript and ɐɯıʇ-ǝɹǝʍ upside-down styles for social media bios.

FAQ

Frequently asked questions

Are these tools free?+

Yes. All 46 tools are free, no sign-up required, no ads, and nothing is stored server-side by this site.

How accurate is the AI content & plagiarism detection?+

The plagiarism checker splits your text and builds verified Google search queries so you can manually confirm matches. The AI detector uses three heuristics — burstiness, AI-phrase density, and vocabulary uniformity — producing a confidence score. For production use, pair these with paid tools like Copyscape or GPTZero.

Does the OCR work offline?+

Tesseract.js loads its language model on first use (~8-12 MB). After that, OCR runs entirely in your browser even if you go offline. First run takes a few extra seconds.

Is Speech-to-Text supported in Firefox?+

Speech-to-Text uses the native Web Speech API, which works best in Chrome, Edge and Safari. Firefox support is currently experimental.

Why do the rewriters produce similar output?+

All rewriters on this page share a synonym dictionary — they swap words with equivalent alternatives rather than invoking an LLM. It's fast and private, but less creative than a paid AI rewriter. Use the output as a starting draft and polish by hand.
