## Rayo (Zero by Rayo)

Rayo is an AI assistant company that has repositioned around a product called Zero. Zero is described as an always-on assistant that runs the work you would otherwise hand off to a person: it can read your inbox, find new leads, draft a summary, and email it on a schedule, then ask for confirmation when it is unsure about an action. The pitch is less about chatting and more about a dependable agent that quietly completes recurring jobs in the background.

The product is currently in a pre-launch, waitlist-driven phase, and the site shows a countdown plus logos of teams that have joined the queue. Access to strong underlying models is part of the value proposition, along with auditability and a privacy-first design. Detailed feature documentation is not yet public at this stage.

Rayo also keeps a legacy SEO automation product live for its existing user base, which is a useful reminder that the company has shipped before and is now betting its next chapter on agentic assistants. Because pricing has not been published, teams interested in Zero should expect to learn commercial terms through the waitlist process.

**Pricing & Plans:** No public pricing is listed yet — Rayo is in a waitlist/pre-launch phase, so commercial terms are expected to be shared with early-access participants.

- **Always-on scheduled agents:** Zero runs tasks on triggers and time schedules — for example, reading new leads every morning at 9am and emailing a summary.
- **Multi-step task execution:** The assistant chains actions such as reading an inbox, identifying leads, drafting an email, and sending it, rather than producing a single answer.
- **Confirmation when unsure:** When an action is ambiguous, Zero pauses and asks before doing something irreversible, such as emailing a specific contact.
- **Access to strong models:** Rayo markets frictionless access to capable frontier models as part of the assistant's core value.
- **Auditability and privacy:** The product emphasizes a fully auditable action log and privacy-first handling of the data it touches.

**Strengths:** Positioned around dependable, scheduled execution rather than one-off chat answers; Confirmation steps reduce the risk of an agent taking the wrong irreversible action; Markets access to high-capability models plus auditability and privacy; Backed by a company with a shipped legacy product, not a brand-new unknown

**Limitations:** Still gated behind a waitlist, so hands-on evaluation is not yet possible; No published pricing or detailed feature documentation at this stage

## 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
