## Overleaf Copilot

Overleaf Copilot solves a very specific friction: academic writers who want ChatGPT's help with their prose, but not the copy-paste loop of opening a chat window, pasting a prompt, pasting their paragraph and pasting the result back into the LaTeX source. The extension attaches a panel to the Overleaf editor, so polishing, grammar checking and translation happen on the text you have selected, in the context of the project you are already working in.

The feature set is aimed squarely at research writing. Besides general polishing, it can follow a stated revision instruction, offers a library of academic prompts that can be shared with colleagues, provides writing suggestions for improving a draft, and handles translation with an academic register rather than a conversational one. Results are written straight to the clipboard, and both shortcuts and panel layout are configurable so the tool can fit different writing habits.

It is important to be clear about what this is: an independent third-party extension developed by a small team of computer science students, not an official Overleaf product. The developers say user content is not stored and merely passed through to the model. The free tier requires the user's own OpenAI API key, while paid tiers supply access to GPT-3.5 or GPT-4 directly. It reports around 4,000 Chrome users and a 4.8 rating across 22 reviews, and is used at 50+ universities according to the vendor.

**Pricing & Plans:** Freemium with a free trial: the Free plan costs nothing forever and uses your own OpenAI API key with practical default agents and prompts. Premium is about $3.9 (¥24.9) per 30 days for unlimited GPT-3.5 and unlimited agents, and Premium+ is about $9.9 (¥59.9) per 30 days for GPT-4 access. Payment runs through Stripe with card, Alipay and WeChat Pay support, and team licences are available on request.

- **One-click academic polishing:** Select a passage and have ChatGPT revise it in place, with the option to state the specific revisions you want.
- **Bilingual grammar checking:** Checks grammar in both English and Chinese, useful for authors writing in a second language.
- **Academic-style translation:** Translates text while preserving academic register and discipline-specific terminology rather than producing generic output.
- **Prompt library and custom prompts:** A library of curated academic prompts that you can browse, reuse and share, plus fully custom prompts for your own style.
- **Shortcuts, layout and clipboard automation:** Assign keyboard shortcuts to each function, adjust the interface layout and have results copied to the clipboard automatically.

**Strengths:** Removes the copy-paste step between ChatGPT and the LaTeX editor; Free tier works with your own OpenAI API key, so there is no mandatory spend; Academic prompt library plus fully custom prompts and shortcuts; Reports 4.8 stars from 22 ratings and use across 50+ universities

**Limitations:** Requires a paid tier or your own API key to get the most useful models; Only works inside Overleaf, so it is useless for other LaTeX setups or Word documents; Unofficial third-party tool, so long-term maintenance depends on a small independent team; Not intended for use in exams or where AI assistance is disallowed

## 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
