Instead of scrolling through a shared album, each guest uploads a single selfie and OPIC's face recognition returns a personal gallery of every image they appear in. Because it runs in the browser, guests do not need to install an app — they scan a QR code or open an event link and are done in seconds. For hosts, the platform is more than a gallery. Events can be shared with branded QR themes, and access is governed by privacy levels such as Guest, Full Access, Photo Selection, and VIP, so a couple can limit certain images while still giving attendees easy access to the rest. Hosts also get analytics covering guest engagement, photo views, and downloads, along with visit tracking and notifications by WhatsApp and email. That combination suits professional photographers who want to offer a polished client experience without building their own delivery portal. OPIC is positioned for weddings and anniversaries, trips and adventures, parties, business meetups, graduations, family and group photos, and baby showers or birthdays. It advertises unlimited events and high-resolution uploads without size restrictions, and offers free storage to new accounts, making it a low-friction option for organisers who want guests to find photos themselves rather than request them. **Pricing & Plans:** A free option with included storage is advertised for new accounts, and larger plans are available. Check the site's pricing page for current tiers and limits. - **AI face recognition:** Guests upload a selfie and instantly receive every photo they appear in, no manual album browsing. - **Flexible privacy levels:** Set Guest, Full Access, Photo Selection, and VIP levels so each audience sees only what you intend. - **Branded QR sharing:** Share events with pre-built themes using QR codes, links, or direct social posts. - **Event analytics and alerts:** Track guest visits, photo views, and downloads, and receive alerts by WhatsApp and email. - **No size limit, unlimited events:** Upload high-resolution images without size caps and run as many events as you need. **Strengths:** Guests find their own photos via selfie, which removes the usual back-and-forth after an event; No app install needed — it works from a browser link or QR code; Granular privacy levels let hosts control access to sensitive images; Analytics and WhatsApp or email alerts give hosts visibility into engagement [Profile (Markdown)](https://openaitools.app/tool/opic.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 OPIC and ZeroGPT compare in monthly traffic?
