## OpenALPR

OpenALPR is the automatic licence plate recognition (ALPR) solution suite built by Rekor Systems, Inc., a publicly traded company (Nasdaq: REKR). It is aimed at organisations that need to turn vehicle sightings into usable data: law enforcement closing cases, property and security teams protecting assets, parking operators processing access and payments, car washes and quick-service restaurants driving loyalty, and software developers embedding vehicle intelligence in their own products.

The suite is built around two core products. Rekor Scout is the vehicle recognition platform that upgrades almost any IP, traffic, or security camera into an ALPR device and surfaces results in a browser, with plans starting at $12 per month. Rekor CarCheck is an API that analyses still images of vehicles and returns plate and vehicle details in JSON, with plans starting at $40 per month. Both are backed by machine learning models that go well past a simple plate read, returning make, model, colour, and direction of travel in real time, with documented, industry-leading read accuracy and recognition across nearly 70 countries.

Operationally, Rekor emphasises fast deployment and low maintenance: a typical installation takes under 20 minutes, software updates are included permanently at no extra charge, and captured plate and vehicle data can be searched by full or partial plate or filtered by attributes, with up to 60 days of retention. A 14-day free trial is available for both products with a credit card, cancellable at any time. For teams needing more control, there is also a vehicle recognition SDK, the ALPR code library, GoSecure deterministic video authentication, and an on-premise licence available on request.

**Pricing & Plans:** Freemium-style trial with paid plans: Rekor Scout starts at $12 per month and the Rekor CarCheck API starts at $40 per month, with flexible plan options and a 14-day free trial that requires a credit card and can be cancelled anytime.

- **Camera-based plate and vehicle recognition:** Rekor Scout reads live video from most IP, traffic, and security cameras and provides real-time vehicle recognition results in any browser.
- **Vehicle recognition API:** Rekor CarCheck accepts still images of vehicles and returns plate and vehicle information as structured JSON for easy integration into your own apps.
- **Full vehicle attributes:** The platform returns plate number, make, model, colour, and direction of travel rather than the plate alone.
- **Searchable vehicle database:** Search a retained database of detections by full or partial plate number, or filter by vehicle attributes, with up to 60 days of data retention.
- **International coverage and fast setup:** Recognition works across nearly 70 countries, updates are free, and typical installs are running in under 20 minutes.
- **SDK and code library:** Beyond the hosted products, Rekor offers a vehicle recognition SDK, the ALPR code library, and GoSecure deterministic video authentication.

**Strengths:** Recognition on almost any existing IP, traffic, or security camera; Goes beyond plates to make, model, colour, and direction of travel; International support across nearly 70 countries; Documented install in under 20 minutes and free software updates

**Limitations:** Now branded as a Rekor Systems product line, so the original open-source project is no longer what the domain sells; Free trial requires a credit card even though it is cancellable anytime; Data retention is capped at 60 days and an on-premise license must be requested separately; Per-camera and per-account pricing scales with deployment size

## 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
