amige. vs
Copyleaks.

Copyleaks is the enterprise plagiarism + AI bundle sold to schools and corporate compliance, with the deepest LMS-integration network in the category and 30+ language coverage. founded 2015 by two ex-IDF engineers, originally a plagiarism product for academic-integrity offices, they pivoted into AI detection when ChatGPT broke through. ten years of selling to procurement teams has given them the most enterprise-flavored footprint in the category.

amige. doesn't play the same game. Copyleaks is a tool you deploy across a university or a corporate compliance department. amige. is a tool you open in a tab when you see something on the internet and want to know if it's real. these are different products for different jobs.

where Copyleaks is stronger

plagiarism. their original product is plagiarism comparison against a large web corpus and institutional databases. for academic-integrity offices, the plagiarism + AI bundle in one tool is the actual buying decision, and amige. doesn't compete in plagiarism at all.

source code. Copyleaks detects copied or AI-generated source code across dozens of languages (Python, Java, C++, C#, JavaScript, Go, Rust, more). this is uniquely theirs in the category and matters in CS-classroom and code-review contexts.

enterprise + LMS distribution. Canvas, Moodle, Blackboard, Brightspace, Schoology, Sakai, Edsby. SMU and University of Michigan-Dearborn switched from Turnitin to Copyleaks in 2024 and 2025. if you're an institutional buyer, this network effect is real and amige. has none of it.

multilingual breadth. 30+ languages claimed, with a 0.03% multilingual FPR figure on their own evaluations. amige. text detection is English-focused.

API for high-volume integration. their public API is volume-priced and built for production embedding. amige. doesn't ship a public API yet.

where amige. is stronger

image and video authenticity. Copyleaks's image support is OCR-for-text-from-images billing (1 credit per image). they are not in the image-authenticity or deepfake-detection business. amige.'s panel is built around exactly that.

model attribution. a flagged image on amige. comes back with the likely generator family ranked by confidence. Copyleaks gives you a percentage and a list of plagiarism-matched URLs. the two outputs answer different questions.

per-detector transparency. amige.'s headline is the verdict-class probability and the per-detector breakdown sits next to it. before the panel weighs in, a trained model reads the marks a generator leaves and routes each scan to the detectors strongest for it; the reads are then fused, calibrated, and the confidence is capped, and amige. returns ‘uncertain’ rather than guess when the panel conflicts. Copyleaks is a single classifier with a single score, so a wrong verdict leaves you nothing to inspect. the full machine is laid out in the machine.

consumer-grade UX and price. Copyleaks is sold to procurement. amige. is sold to a person. $13.99 per month after a 2,500-word free tier versus $9 per month after 3 free scans per day with no signup required.

accuracy: what the numbers show

Copyleaks markets 99% accuracy and 0.2% false-positive rate. these are their own headline numbers. independent reviewers report real-world FPR closer to 5% in some content classes, several times their headline, with non-native English writing the worst case. Copyleaks-authored research finding 60% of GPT-3.5 outputs contain plagiarism has been cited in OpenAI class-action filings, which is an unusual cross-pollination for a detection vendor and a signal of how seriously courts have taken their methodology. false positives on ESL writing are the sharpest risk in the school context where Copyleaks sells.

amige. doesn't headline a single accuracy number. most detectors in this category claim 99% and measure 65% to 90% in independent tests, with ESL writing the worst-affected category. we'd rather show our panel arguing than one confident percentage that overpromises.

AI in code, and inside the LMS

Copyleaks detects AI-written source code and runs across 30+ languages, sitting inside the plagiarism and LMS stack a university already uses. amige. doesn't touch code or plagiarism; it checks whether an image, video or passage is AI and names the likely model.

who each is for

pick Copyleaks if you run an academic-integrity office, a corporate compliance function, or a CS department. you need plagiarism + AI + source code in one product. you need Canvas / Moodle / Blackboard integration. you need an API for production embedding. you have a procurement budget.

pick amige. if you want to check whether an image is AI in twenty seconds. you want to know which model produced a deepfake video. you want a shareable permalink to send to your skeptical group chat. you want to spend $9 a month or zero. you do not want to talk to a sales team.

these are different products. if you're a buyer for an institution, Copyleaks is the right shape. if you're a person with a question about a piece of content, amige. is.
