## Gorby

Gorby is built for writers who want feedback while drafting rather than after. As you type, it quietly checks readability and style, marking complex sentences, passive constructions, qualifiers, cliches, redundancies and overused phrases directly in the text. Colour-coded sentence highlighting reveals the rhythm of your prose, showing where your cadence flattens out or where a comma should have been a full stop.

The readability side is unusually thorough for a browser tool. Flesch Reading Ease, Dale-Chall, ARI and SMOG scores tell you the approximate grade level of a passage, so you can match a blog post, a student essay or a technical manual to its intended audience. Extra checks cover acronym usage, article errors, repeated wording and keyword density, and NLP tagging labels nouns, verbs, adjectives and other parts of speech for granular review. Reports bundle statistics, scores and highlights into an exportable PDF.

Privacy is the other half of the pitch. Gorby runs in the browser and states that your drafts are never stored on its servers, and no account is needed to start analysing text. Focus Mode swaps menus and toolbars for a paper-like surface with optional typewriter sounds, ambient audio and a session timer, while writing goals add a progress bar and completion chime. Paid plans additionally include AI-powered rephrasing and synonym suggestions, and there is a desktop app for offline work.

**Pricing & Plans:** A free tier covers core analysis without an account. Paid options listed on the site include Monthly at $12/month, Yearly at $59/year, and Lifetime at $119 as a one-time payment, with 20,000 AI credits on yearly and 35,000 on lifetime, plus a 14-day money-back guarantee. Check the official pricing page for current details.

- **Live style and clarity checks:** Passive voice, complex sentences, qualifiers, cliches, redundancies and overused words are highlighted in context the moment you write them.
- **Readability scoring:** Flesch Reading Ease, Dale-Chall, ARI and SMOG scores show the grade level of your text so you can write for a specific audience.
- **Sentence rhythm visualisation:** Colour-coded sentences reveal where the cadence flattens, helping you vary length and keep readers moving.
- **Focus Mode writing surface:** A paper-like, distraction-free editor with optional typewriter sounds, ambient audio and a session timer for deep work.
- **Privacy-first architecture:** Gorby runs in the browser, needs no account to start and states that your drafts are never stored on its servers.

**Strengths:** Readability metrics such as Flesch, Dale-Chall, ARI and SMOG are built directly into the editor.; Privacy-first design with no account needed to start and no drafts stored on the servers.; Focus Mode plus ambient audio and a session timer supports genuinely deep writing sessions.; Paid plans are affordable and arguably economical, with optional AI rephrasing on top of rule-based checks.

**Limitations:** The rule-based checks can feel noisy if you prefer to edit only after finishing a full draft.; AI rephrasing and synonyms sit behind a paid plan, so the free tier is analysis rather than rewriting.; Some advanced features, such as deeper reports, are best experienced as regular users rather than one-off visitors.

## 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
