The product answers that with a detector that returns an overall AI likelihood score and highlights individual sentences it considers machine-written, so a reader can see where the suspicion comes from rather than just receiving a single verdict. Over time the platform widened from a single text box into a suite aimed at institutions. Detector results are paired with a plagiarism checker, grammar and writing feedback, and optional process verification such as a writing replay that records how a document was typed. A Chrome extension and Google Docs add-on push detection into the tools students and staff already use, and the company offers classroom integrations plus an API for bulk or programmatic checks. Because the buyers are largely schools, districts, and universities, GPTZero leans heavily on privacy and compliance claims: it states SOC 2 Type II compliance and alignment with FERPA, GDPR, and CCPA, and says student writing is not used to train models. The practical takeaway is that it is positioned as an academic-integrity and editorial-review tool rather than a novelty checker, which also means its more powerful features sit in paid tiers. **Pricing & Plans:** 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. **Strengths:** 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 **Limitations:** 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 [Profile (Markdown)](https://openaitools.app/tool/gptzero-me.md) ## Stenography Stenography tackles a persistent developer chore: keeping code documented. Its central feature, Autopilot, watches your codebase and documents it automatically as you save, so explanations stay close to the code they describe instead of drifting out of date. Under the hood it is powered by an API that accepts a block of code and returns an explanation in plain English. Because that API is public, you can use it beyond the built-in integrations: build your own extension, wire it into a review bot, or explain snippets programmatically. Responses can be enriched with Stack Overflow suggestions and linked documentation from around the web, cutting down on manual searching. Stenography is privacy-conscious by design — it describes a passthrough API that does not store your code. It is the work of Bram Adams, an OpenAI Developer Ambassador, and offers 250 free API invocations per month, making it easy to evaluate before committing to a paid plan. **Pricing & Plans:** Stenography is freemium: the API includes 250 free invocations per month on VSC or your own extension. Paid plans are available for heavier use, and enterprise or custom arrangements are handled by contacting the team. - **Autopilot documentation:** Autopilot documents entire codebases every time you hit save, so documentation keeps pace with your code. - **Code explanation API:** Pass in code and receive an explanation in plain English, customizable to your needs through a public API. - **Stack Overflow and doc suggestions:** Enrich generated explanations with Stack Overflow suggestions and documentation from across the web so you do not have to search manually. - **Editor and tool extensions:** Integrations for editors and wherever code can be found, including the VSC extension. - **Privacy-first design:** A passthrough API that does not store your code, keeping sensitive source on your own system. - **Free monthly usage:** The API includes 250 free monthly invocations to try on VSC or your own extension. **Strengths:** Automates documentation continuously via Autopilot; Public API lets you build your own integrations; Enriches explanations with Stack Overflow and linked docs; Privacy-first passthrough that does not store code **Limitations:** Best value comes from the VSC/editor extensions, so CLI-only users get less; Autopilot quality depends on the underlying models used; The product's marketing and examples date from the GPT-3 era and updates are infrequent; Plain-English explanations still need review for critical code [Profile (Markdown)](https://openaitools.app/tool/stenography.md) ## Frequently Asked Questions ### How do GPTZero and Stenography compare in monthly traffic?
