SynthQuery for Teachers — AI Detection, Plagiarism, Citation
Teachers need to assess student writing fairly in a world where AI assistance is one click away. SynthQuery gives you sentence-level AI detection across the models students actually use, plus plagiarism checking and readability scoring — all in one subscription with a free tier for evaluation.
What gets in your way
Detector accuracy varies wildly across models
Many free detectors were trained on GPT-3-era outputs and miss recent Claude, Gemini, and Llama writing. SynthQuery publishes per-model accuracy so you can see realistic numbers, not marketing claims.
False positives put honest students at risk
A single tool's flag isn't proof. SynthQuery shows confidence scores at the sentence level, so you can review specific passages rather than a single document-level percentage.
Stacking tools gets expensive on a school budget
Detector + plagiarism + grammar + citation as separate subscriptions costs $50+/month. SynthQuery bundles all four in a flat $29/mo Pro plan, and the free tier is usable for occasional checks.
Students are already using humanizers
Pretending humanizers don't exist doesn't help. SynthQuery's detector is tuned against humanized output, and we publish accuracy on humanized text so you know what to trust.

FAQ
- Is SynthQuery FERPA-compliant?
- We don't sell or share submitted text. Always check your district's data-handling policy before submitting student work to any third-party service. SOC 2 Type II is in progress.
- Can I trust a single detector flag?
- No — and we don't ask you to. Use detector confidence as one signal among several (plagiarism check, in-class writing samples, conversation with the student). Sentence-level highlights help you focus on specific passages rather than a black-box percentage.
- What about students who use humanizers?
- Our detector is trained on humanized output as well as raw AI output. Per-model accuracy on humanized text is published on the methodology page.
- Is there a free tier for teachers?
- Yes. The free tier is suitable for occasional checks. Pro at $29/mo is sensible for teachers running checks weekly across multiple classes.
- Can I export results for academic integrity reports?
- Yes — every check produces a PDF report with sentence-level highlights, plagiarism sources, and citation matches that you can attach to integrity-board submissions.
