## Citely

Unlike a plain text generator, Citely is positioned as a verification layer for academic work. The core workflow is simple: paste a reference list, and Citely resolves each entry against scholarly databases, returning a status for every citation. Entries with DOIs that do not resolve, author-year combinations that do not match the record, or venues that do not exist are surfaced clearly, which is exactly the failure mode produced when a language model invents plausible-looking references.

The second half of the product works in the opposite direction. The AI Source Finder takes a claim or a paragraph and searches the same indexes for genuine papers that support it, returning citations with verified metadata. For students writing essays, thesis candidates assembling literature reviews, and editors screening submissions, that combination covers both sides of the problem: proving that a source is real, and finding a real source to support a point.

Citely is a browser-based tool with paid tiers that meter usage in credits. A one-off trial plan unlocks a single verification run, monthly and yearly subscriptions grant a recurring credit allowance plus citation export, and a multi-year "Believer" tier is aimed at long-running research projects. Character ceilings differ between the Source Finder and the reference checker, so the size of a reference list affects how many credits a run consumes.

**Pricing & Plans:** Citely uses a credit-based model with four published tiers: a $9 one-time trial, $19/month billed monthly, $14/month billed yearly, and a $347 one-time three-year Believer plan. Higher tiers raise the credit allowance, extend the character limit for reference verification from 2,000 to 4,000 characters, and add citation export in APA, MLA, and Chicago. Enterprise and larger credit bundles are available on request.

- **AI Source Finder:** Paste a claim or paragraph and Citely returns matching academic papers with verified metadata, ready to cite in APA, MLA, or Chicago style.
- **Citation & Reference Checker:** Submit a reference list and Citely tests each entry against scholarly databases, marking entries that cannot be confirmed or that point to the wrong work.
- **AI Hallucination Detection:** Citely targets the specific errors AI models make when inventing references, including chimera citations, invented DOIs, and citations that drift across years.
- **Multi-Database Verification:** Checks run against CrossRef, PubMed, arXiv, and OpenAlex, so verification reflects real indexed scholarship rather than a single narrow database.
- **Citation Export:** Export verified references in common academic styles so they drop straight into a manuscript or reference manager.

**Strengths:** Verifies references against multiple real academic indexes instead of trusting a single source; Directly targets AI-written citation hallucinations such as invented DOIs and chimera citations; Doubles as a source finder when you have a claim but no reference for it; Exports citations in standard academic styles

**Limitations:** Credit-based billing means heavy reference lists can consume an allowance quickly; Character limits apply per Source Finder (300) and Verify References (2,000) run; Advanced source verification, citation export, and higher character ceilings sit behind paid plans; No native Zotero/Mendeley sync shown on the public site, so library workflows stay partly manual

## 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
