## Omnilert

Omnilert is a physical security company that pioneered visual AI gun detection and layers it on top of an established emergency notification business. Its core proposition is straightforward: most organizations already have cameras watching large indoor and outdoor areas, but those cameras are passive. Omnilert's patented computer vision adds an active layer that scans live video for firearms and active-shooter threats, then escalates far faster than a human doing the same job across dozens of feeds.

The workflow runs in three steps. First, AI analysis rooted in U.S. Department of Defense and DARPA research on real-time threat recognition flags a potential weapon. Second, a human — either Omnilert's UL-certified monitoring operators or your own security staff — verifies the event. Third, the platform automates the response: locking doors, sounding alarms, pushing alerts with time, location and photos, engaging displays and dispatching authorities.

It also functions as a broader emergency communication and security automation platform. Mass notification, security workflow automation and AI camera health monitoring sit alongside gun detection, and an open integration approach connects to more than 50 security partners. Its built-in emergency response management system holds a U.S. Department of Homeland Security SAFETY Act designation, and the company reports supporting more than 1,000 organizations across education, healthcare, government, retail, banking, transportation and more.

**Pricing & Plans:** Omnilert is sold as a quote-based enterprise solution. The vendor asks prospective customers to request a demo or contact sales for pricing, which typically varies with camera count, number of sites and which modules (gun detection, notification, workflow automation, camera health) you deploy.

- **AI gun detection from existing cameras:** Turns passive surveillance cameras into proactive early-warning systems that recognize firearms and active-shooter threats in a fraction of a second.
- **Automated emergency response:** Triggers coordinated actions the moment a threat is confirmed: locking doors, sounding alarms, pushing mobile alerts, engaging displays and notifying police.
- **Human verification options:** Choose UL-certified professional monitoring or human-in-the-loop review within your own security operations center to confirm alerts before response.
- **Mass notification and emergency communication:** Delivers detailed real-time alerts with time, location and imagery across mobile, desktop and on-premise displays, built on long-standing emergency notification expertise.
- **AI camera health monitoring:** Detects more than 120 camera issues — blur, obstruction, rotation, poor lighting and more — that could compromise detection, analytics or investigations.

**Strengths:** Purpose-built for real-world gun threat detection with DARPA-rooted computer vision; Combines detection with automated response instead of only generating alerts; Works with existing security cameras and 50+ integration partners; Only AI gun detection solution with a built-in emergency response system holding a DHS SAFETY Act designation

## 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
