## Write Brain

Write Brain is a lightweight writing assistant that lives inside your browser as a Chrome extension. Rather than asking you to paste text into a separate app, it attaches a small menu of improvement commands to whichever text box you are already typing in. That means it can help while you are composing a LinkedIn post, replying in Gmail, leaving a YouTube comment, or filling out an online form.

The core idea is speed. You type naturally, then use the extension to clean up grammar and typos, remove fluff, sharpen your wording, or change the tone so it fits the context. Because it works in place, you avoid the copy-paste round trip that standalone grammar checkers require.

Beyond proofreading, Write Brain adds a few creative touches: it can translate text to or from your home language, which is handy for reading foreign comments or answering international customers, and it can suggest emoji for headings and list items. It is a general-purpose helper for people who write a lot on the web and want quick, low-friction improvements rather than a full document editor.

**Pricing & Plans:** Freemium. The extension is free to install from the Chrome Web Store, and the store listing indicates in-app purchases are available for paid features or higher usage limits.

- **One-click grammar fixes:** Automatically spot and correct typos and grammar slips in any text field and fix them with a single click before you send.
- **Conciseness and clarity:** Strip out verbose corporate phrasing and unnecessary words to turn rambling drafts into clear, direct messages.
- **Writing enhancement:** Turn a rough outline into richer, more descriptive prose with quick suggestions on how to phrase your point better.
- **Inline translation:** Translate text in place, so you can read foreign-language comments or reply to customers in their own language.
- **Emoji suggestions:** Get context-appropriate emoji suggested for paragraph endings and as bullets for list items to add personality.

**Strengths:** Works directly inside any website's text fields, no copy-paste required; Covers grammar, conciseness, tone, translation, and emoji in one menu; Fast, one-click improvements suited to short-form and social writing; Lightweight browser extension with a simple learning curve

**Limitations:** Requires installing a Chrome extension before most features work; No dedicated desktop or mobile app; Feature set is narrower than full document editors like Google Docs add-ons; Grammar and rewrite quality can miss nuanced or technical language

## ZeroGPT

ZeroGPT is best known as an AI content detector, but the site has expanded into a full writing and verification toolkit. The core AI/GPT detector lets you paste text or upload a file and returns a highlighted analysis showing which sentences look machine-written, with a percentage gauge and an automatically generated PDF report you can use as documentation.

Around that core sit several companion detectors and writers. The AI image detector and AI video detector extend checking beyond text; the plagiarism checker scans against billions of sources; and the AI humanizer and paraphraser rewrite text into a more natural style. A grammar checker, summarizer, translator, dictionary, word counter, citation generator, and AI email helper round out day-to-day writing tasks. The company says its multi-stage DeepAnalyse model is trained on internet text, educational datasets, and proprietary synthetic AI datasets, covers over 35 LLM families, and reports 98.4% detection accuracy with a false positive rate under 1%.

Access is freemium: the main tools work free in the browser, with MAX and EXPERT subscriptions for heavier use and premium features, and a separate API for organizations that need large-scale integration. ZeroGPT also runs on WhatsApp and Telegram through a bot, letting you chat, detect AI text, summarize, paraphrase, translate, and check grammar without leaving the messaging app.

**Pricing & Plans:** Freemium with paid tiers. Core tools such as the AI detector, summarizer, and grammar checker are usable free in the browser, while MAX and EXPERT subscriptions unlock higher limits and premium features, and API access is sold separately for organizations.

- **AI and ChatGPT detection:** Paste up to 15,000 characters or upload a file and get a highlighted breakdown of which sentences appear AI-written, plus an overall percentage score and a downloadable PDF report.
- **AI image and video detection:** Beyond text, ZeroGPT offers an AI image detector and an AI video detector that performs frame-level analysis to flag generated or manipulated visuals.
- **Plagiarism checking and humanizing:** Compare your text against billions of sources through the plagiarism checker, or rewrite and humanize AI text with the paraphraser and AI humanizer while keeping the original meaning.
- **Writing and productivity tools:** A bundled writing suite covers summarization, grammar and spelling correction, translation across many languages, a dictionary, word and character counting, citation generation, and an AI email writer.
- **API for organizations:** A documented REST API exposes detection, plagiarism, paraphrasing, summarization, grammar, chatbot, and translation endpoints for organizations that need to embed ZeroGPT at scale.

**Strengths:** Free browser access to the core AI detector, summarizer, and grammar checker; Sentence-level highlighting with an overall percentage and exportable PDF reports; Extends beyond text to AI image and video detection, plus plagiarism checking; Broad companion toolkit: humanizer, paraphraser, translator, dictionary, citations, email helper

**Limitations:** AI detectors can produce false positives, so results should be treated as a signal rather than proof; The strongest features sit behind MAX/EXPERT paid tiers and API access is a separate purchase; Character limits apply to the free detection box; No detection tool can guarantee correctness across every model and language
