## Crazyrouter

Crazyrouter positions itself as a unified access layer for AI models. Rather than holding accounts with a dozen providers, you create one API key in the console and route chat, image and video requests through a single endpoint. The platform is explicitly compatible with the OpenAI, Anthropic and Gemini request formats, which means the migration path is usually a one-line change: point your SDK's base_url at Crazyrouter, swap in the key, and start calling. Existing code structure stays intact, and teams can move to the gateway first and then shift individual model choices over gradually.

The advertised catalogue spans mainstream frontier models alongside Chinese and video-generation models — Claude, GPT, Gemini, DeepSeek, Qwen, Kimi, MiniMax, Kling and Sora are among the names it highlights. Pricing is published per model and sorted by input cost, and the site says its rates run below official list pricing thanks to public discounts layered on pay-as-you-go billing. Because billing is metered, costs track real usage rather than fixed seat fees.

On the infrastructure side, Crazyrouter markets multi-node smart scheduling that picks a faster path per request, redundant links and failover designed to absorb a single point of failure, and centralised quotas so calls, prices and limits are visible in one place. It also publishes developer documentation and a model pricing view. Two caveats matter: the platform openly states it is an independent third party with no official authorisation, sponsorship or endorsement from the brands whose models it resells, and that brand names appear only to identify compatible models.

**Pricing & Plans:** Pay-as-you-go / metered billing with no subscription mentioned. Publicly listed per-model rates sorted by input price, described as below official pricing due to standing discounts. Supports Chinese yuan payment, invoicing, and one balance that covers chat, image and video models. Credits are consumed according to the model selected and usage volume.

- **One key, many models:** Create a single API key and call hundreds of text, image and video models without managing separate accounts at each provider.
- **OpenAI/Anthropic/Gemini compatible endpoints:** Requests follow the common formats, so existing SDKs and CLI tools (including Claude Code and Codex CLI) work after changing only the base URL.
- **Published per-model pricing:** A pricing view lists popular models sorted by input cost and links straight to a filtered price page, making cost comparison straightforward.
- **Smart multi-node routing:** Multiple nodes schedule requests dynamically to reduce wait time, with redundant links and failover to limit the impact of any single outage.
- **Centralised quotas and billing:** Calls, prices and limits are managed in one console, with pay-as-you-go metering, CNY payment and invoice support.

**Strengths:** A single key and base URL replace juggling accounts across many providers; Request formats match OpenAI, Anthropic and Gemini conventions, so switching is usually a one-line change; Per-model pricing is published and sortable, which makes cost comparison easy; Supports CNY payment and invoicing, useful for teams that need local procurement

**Limitations:** It is an unofficial third-party reseller, so you depend on an intermediary rather than a provider's own account and SLA; The site's advertised model count is inconsistent (300+ and 600+ both appear), so verify specific models before relying on them; As an aggregator, availability and exact pricing for any model can change without the notice you'd get directly from a vendor

## 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
