The product now centers on a visibility dashboard that runs your chosen prompts across several AI platforms daily, showing where your brand is recommended, cited, or missing compared with competitors. The platform organizes work into what it calls the AI Search Loop: track visibility and citations, prioritize the highest-impact gaps, act through an AI agent that rewrites and structures pages, and measure whether rankings and citations improved. Alongside monitoring, Writesonic still includes an AI article writer, site audits, and outreach drafting for external citations. Positioning is aimed at marketing teams, agencies, and enterprises that want SEO and GEO handled in one place. Self-serve plans start around $79 per month billed annually, with usage scaling by tracked prompts, AI articles per month, and seat count, up to custom enterprise agreements. **Pricing & Plans:** Freemium-style entry with a 7-day free trial and no credit card required. Self-serve plans run roughly $79/month (Starter), $199/month (Basic), and $399/month (Growth) when billed annually, with a 20% annual saving. Enterprise pricing is custom and quoted on request. - **AI visibility tracking:** Monitor brand mentions, competitive rank, citations, and sentiment across ChatGPT, Gemini, Perplexity, Google AI Overviews, and other AI platforms using daily prompt runs. - **Action Center prioritization:** A ranked list of visibility and citation opportunities—missing prompts, content gaps, and technical issues—so teams know which few fixes to make each week. - **AI agents for content and pages:** Agents rewrite pages for GEO, add FAQ blocks, comparison tables, and self-contained passages that AI engines tend to cite. - **AI article writer and site audits:** Generate dozens of SEO/GEO articles per month and run automated site audits covering crawlability, schema, and indexing. - **Outreach and technical fixes:** Surface Reddit threads, YouTube videos, and high-authority listicles citing competitors, draft outreach, and auto-fix robots.txt or schema issues blocking AI crawlers. **Strengths:** Combines GEO/AEO monitoring with the content and outreach work needed to actually improve results; Covers multiple AI platforms including ChatGPT, Gemini, Perplexity, and Google AI Overviews; Includes an AI article writer and site audits, so SEO and GEO can live in one tool; Self-serve entry pricing is transparent, with a no-credit-card free trial **Limitations:** Only three AI platforms are tracked on lower self-serve tiers; all eight require Enterprise; Some headline features such as the full Action Center and Sentiment Analysis are gated to higher or Enterprise plans; Prompt, answer, article, and user counts are capped per tier and add cost as you scale; Teams mainly after a simple writing tool may find the GEO-first positioning heavier than needed [Profile (Markdown)](https://openaitools.app/tool/writesonic.md) ## 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 [Profile (Markdown)](https://openaitools.app/tool/zerogpt.md) ## Frequently Asked Questions ### How do Writesonic and ZeroGPT compare in monthly traffic?
