The conversion library covers documents (PDF, DOCX, EPUB, RTF, LaTeX), web sources (URL, HTML, YouTube transcripts, podcasts, WeChat, Bilibili, Reddit, LinkedIn, X, TikTok, Xiaohongshu), spreadsheets and structured data (CSV, JSON, Excel), and platform targets such as Notion, Google Docs, Confluence, Slack and Obsidian. The product is deliberately browser-first. Where a format allows it, conversion happens locally on your device, and the site states that files are not uploaded or retained unless you explicitly opt into AI/OCR processing for scanned or complex inputs. A built-in Markdown viewer doubles as an editor with GitHub Flavored Markdown, LaTeX math support, syntax highlighting and export to PDF, HTML or .md. Pricing follows a freemium shape: the core browser-side tools are usable without an account, while Pro and Team plans unlock more AI/OCR credits, higher content-link limits, an ad-free experience, team seats and support. For one-off conversions or non-technical users it is a fast alternative to command-line tools like Pandoc, though it is not a replacement for batch automation in CI pipelines. **Pricing & Plans:** Freemium. Core browser-based converters and the Markdown viewer are free without signup; Pro and Team plans add AI/OCR credits, higher limits, ad-free usage and team seats. Check the pricing page for current tiers. - **37 focused Markdown tools:** Separate converters for documents, web links, spreadsheets, ebooks and platform-specific content, all behind a consistent interface. - **Browser-first and private:** Core conversions run locally where the format allows, so files stay on your device.

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 [Profile (Markdown)](https://openaitools.app/tool/zerogpt.md) ## Frequently Asked Questions ### How do 2MarkDown.io and ZeroGPT compare in monthly traffic? 2MarkDown.io has 8,899 monthly visits, while ZeroGPT has 32,864,541.
