## GPTZero

GPTZero grew out of the practical problem that teachers and editors faced once generative text became common: how do you tell whether a piece of writing came from a person or a model? 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

## StoryNotes

StoryNotes is a screenplay coverage tool for screenwriters who want a fast, honest read on their draft. A writer uploads a script and receives coverage in about five minutes, organized into stages with letter grades. It avoids vague encouragement, instead citing specific pages when it evaluates a scene, a character function or a tonal shift, and it ends with three concrete rewrites to try.

Coverage covers the craft dimensions that matter most in a spec script. The opening stage assesses genre, tone and the function each principal character is serving, noting where obligations of a genre are honored and where they are not. Later stages examine the premise and core story engine — the structural bets the whole script is making — along with how well those bets pay off. By anchoring every observation to a page number, the tool produces notes you can check against your own draft rather than generic advice.

The service is priced for individual writers: the first stages are free, and full coverage costs $20 one-time per script with no subscription. A public sample analyzing the 1963 screenplay Charade is available on the site, so you can see the depth and format of the analysis before paying. StoryNotes targets writers preparing for contests, agents or production who want a low-cost first reader before investing in human notes or professional coverage.

**Pricing & Plans:** Freemium: the first coverage stages are free, and full coverage is $20 one-time per screenplay with no subscription.

- **Multi-stage AI coverage:** Upload a screenplay and receive structured analysis across genre and tone, premise and story engine, structure, theme and characters.
- **Letter grades per stage:** Each stage comes with a letter grade and clear highlights of what works, plus specific problems to address.
- **Page-level citations:** Feedback points to exact page numbers — for example, citing a scene at a specific page and line context — so notes are verifiable against your draft.
- **Concrete rewrite suggestions:** Rather than abstract advice, StoryNotes proposes three concrete rewrites you can try on your next pass.
- **Free first stages:** The opening stages are free to run, letting you evaluate the quality of the read before committing.

**Strengths:** Fast turnaround — about five minutes for a full read; Honest, specifically cited feedback with page numbers rather than flattery; Concrete rewrite suggestions you can actually apply; Low one-time cost of $20 with no subscription commitment

**Limitations:** Coverage is analytical feedback from an AI, not a human executive's recommendation; Only useful for screenplays — not for novels, stage plays or other prose; Detailed rewrite suggestions cost the one-time fee rather than being fully free; No collaborative or team features advertised
