## 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.

**料金とプラン:** 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.

**強み:** 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

**制約・デメリット:** 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

## Postdit

Postdit is an AI influencer generator that lets you design a fictional character — woman or man — lock their face with a 12-angle turnaround, give them a voice, and produce consistent photos, motion clips and lip-synced talking reels.

**料金とプラン:** Freemium with 250 free credits, no card required, then monthly subscriptions at $19/month (Starter), $49/month (Creator) and $129/month (Studio), plus credit top-ups.

- **12-angle character locking:** Generate a full turnaround — face, profiles and full-body front, side and back — so the identity stays identical across every future render.
- **Photo shoots up to 2K:** Place your character in gyms, beach clubs, penthouses, streets and other scenes and export high-resolution images ready for posting.
- **Motion clips and talking reels:** Animate any still photo into a 5–10 second 9:16 clip, or render a lip-synced talking reel from a script with word-timed captions.
- **Designed voices in 14 languages:** Give each character a consistent voice for reels and personal voice notes to fans, across 14 supported languages.
- **Muse, the built-in AI director:** Ask for scene ideas, scripts and fixes in plain words, or let it plan and run a shoot cycle for the character on your behalf.

**強み:** Solves the identity-drift problem with a reusable 12-angle locked character sheet; One character spans stills, motion clips and lip-synced talking reels; Fourteen ready-made fictional personas make it easy to start immediately; Clear content policy and AI-labelled exports remove ambiguity about what is allowed

**制約・デメリット:** Newer, narrower product than general-purpose social schedulers — it builds AI characters rather than managing your existing accounts; Credits are consumed quickly by motion clips and talking reels; Strict policy limits: fictional adults only, no real-person cloning, no explicit content; Prompt design and character consistency still take iteration to get right
