## 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

## Gard (imgProof)

Gard — known as imgProof before its rebrand — is instant graphic design review software built with AI at its core. Where standard spellcheckers only see editable text, Gard reads the copy baked into exported images and PDFs: packaging labels, campaign assets, email graphics, posters and print artwork. It uses reasoning to flag potential spelling, grammar, consistency, translation and even measurement-conversion errors in context, so teams catch mistakes before assets go to print or into a live campaign.

The workflow is simple and brief-driven. You drop in an image or PDF alongside a design brief, review the suggested corrections, and share the results. Each suggestion can be confirmed or ignored, and the tool is explicit that its AI can hallucinate — suggestions are there to support a human reviewer, not to auto-approve artwork. It is used in early drafts, revision rounds and final QA, and works for roles from proofreaders and designers to marketers and copywriters.

Gard says it is trusted by more than 4,000 individuals and teams, and its pricing scales by scan volume and creative review features, from a low-cost Lite tier for independent creators up to a Pro plan for teams and agencies. A 14-day free trial is available.

**Pricing & Plans:** Free 14-day trial, then paid plans billed monthly or yearly (yearly saves about 17%). Annual rates: Lite $7/month billed $90/year (300 scans/year, 1 seat); Starter $24/month billed $288/year (1,200 scans/year, 1 seat); Pro $74/month billed $888/year (6,000 scans/year, 5 seats, folder watch, priority email support). A Contact Sales option exists for higher volumes. Confirm current pricing on the pricing page.

- **AI copy proofing inside images:** Scan exported images and PDFs to surface potential spelling, grammar, punctuation, consistency and translation errors in the visible copy.
- **Design brief comparison:** Upload a design brief alongside the artwork so Gard can check offers, prices, dates and mandatory copy against your requirements.
- **Review corrections in context:** Each correction is shown in context with Confirm or Ignore options, so reviewers stay in control of what actually changes.
- **Share and export results:** Share scan corrections by link and export a corrections PDF, so QA, design and marketing teams can collaborate and sign off faster.
- **Batch proofing for teams:** Batch-scan multiple ad variants or SKUs, and on higher plans add folder watch, more seats and priority support.

**Strengths:** Catches copy errors that regular text spellcheckers miss because it reads text inside images and PDFs; Works across packaging, ads, email images and print artwork; Design-brief comparison checks offers, prices and mandatory copy; Shareable links and PDF correction exports fit team QA workflows

**Limitations:** No free tier forever — it is a 14-day free trial, then paid plans; Annual billing is default; monthly costs more; AI can hallucinate, so every suggestion needs human review; Focused on proofreading copy in images, not a full design editor
