## GPTZero

GPTZero is an AI detection platform for identifying machine-generated text. It combines a text detector with a Chrome extension, a plagiarism checker, writing-process verification, and educator-focused classroom tools.

**Preços e planos:** Freemium plus paid plans. A free tier provides core detection with character limits per scan, while paid individual and institutional plans unlock advanced scan modes, higher limits, writing reports, and classroom integrations. Enterprise and API access are quoted separately.

- **Sentence-level AI detection:** Paste text or upload a document and get an overall AI probability score plus a sentence-by-sentence breakdown of which parts look machine-written.
- **Multi-model coverage:** Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
- **Browser and docs extensions:** A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
- **Plagiarism checking:** Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.
- **Writing process verification:** Writing replay and advanced reports offer evidence about how a document was produced, useful for academic integrity workflows.

**Pontos fortes:** Sentence-level highlighting shows why a passage was flagged instead of only giving a score; Covers text from many different AI model families, not just one chatbot; Integrations with Chrome, Google Docs, Canvas, and Google Classroom fit existing school workflows; Publishes concrete compliance claims (SOC 2 Type II, FERPA, GDPR, CCPA) that institutions can review

**Limitações:** Detection is probabilistic and can flag polished human writing or miss lightly edited AI text; Free scans are capped by character count, and useful reporting features require payment; Lean heavily on a single score without human judgment can lead to unfair accusations

## ScienHub

ScienHub is a browser-based collaborative LaTeX editor with real-time multi-user editing, fast compilation, Git version control and templates, positioned as a free alternative to established online LaTeX suites.

**Preços e planos:** ScienHub states that all features are free for now, with no subscription and no credit card required. The site includes a pricing page, so check it for the current position before relying on free access long term.

- **Real-time collaboration:** Multiple authors edit the same document at once and see each other's changes immediately, which suits research teams and supervisors.
- **Fast in-browser compilation:** Compile in the browser without installing a local LaTeX distribution and preview your typeset output as you write.
- **Git version control:** Track revisions and sync your source properly using Git version control instead of renaming files by hand.
- **Templates for papers:** Start from LaTeX templates instead of a blank document, useful for standard paper and report structures.
- **No installation required:** Everything runs on the web with no setup, so you can write from any machine without configuring a toolchain.

**Pontos fortes:** Real-time collaborative editing removes the file-emailing workflow; Compiles in the browser with no local LaTeX installation; Built-in Git version control for proper revision tracking; Currently free with no credit card required

**Limitações:** Advanced features are stated as free 'for now', so future pricing is not guaranteed; Fewer surrounding scholarly services than the most established LaTeX suites; Community groups were still marked coming soon at the time of review; Smaller ecosystem means fewer third-party templates than larger platforms
