AI detection and writing verification built for schools and editors
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.
Flags AI text from major model families including ChatGPT, Gemini, Claude, Llama, and others, rather than training for a single model.
A Chrome extension and Google Docs add-on bring scanning into Gmail, Docs, Classroom, and other surfaces you already work in.
Checks content for copied passages from outside sources so you can separate AI-generation questions from originality questions.
OpenAI's open-source speech recognition model for transcription, translation and language ID
One Transformer handles transcription, speech translation into English, language identification and voice activity detection, selected through special task tokens.
Choose from tiny, base, small, medium, large and turbo checkpoints, with English-only .en variants, to balance accuracy against VRAM and speed.
Multilingual checkpoints transcribe and translate dozens of languages, with automatic language detection on mixed-language audio.
Install via pip with openai-whisper and transcribe files from the terminal or from your own Python code, with ffmpeg handling audio decoding.
Offers broad multilingual AI detection and text humanization, but lacks GPTZero's detailed deep-scan reporting features.

SpecialistCombines AI detection with professional human proofreading and citation tools, but functions primarily as an editing service.
#2
AI transcription and meeting notes in 150+ languages
SpecialistCombines AI detection with robust text humanization tools, but focuses more heavily on rewriting than pure verification.

Provides robust enterprise-grade content integrity and cross-media detection, but can be more expensive for individual users.


Delivers strong fact-checking and comprehensive site-wide plagiarism audits, but has stricter paywalls than GPTZero.

Turn any video or audio into text in seconds

Provides detailed sentence-level analysis for multilingual text, but lacks GPTZero's broad academic brand recognition.
Real-time speech-to-text, text-to-speech and voice agents in one API platform

AI transcription that turns audio and video into searchable text

Excels at scanning both text and images with high accuracy, but offers fewer free daily checks than GPTZero.
AI detector that highlights evidence, not just a score
