Honesty note on AI detektor:
AI detections havana kuvimbika. Academic research (Stanford HAI, Vanderbilt, University of Maryland) inoratidzwa fake-positive rates of 5–15% on genuine student writing and fake-negative rates that climb above 30% on modern models (GPT-4+, Claude, Gemini). Our score reflects pattern-matching heuristics (perplexity, burstiness, AI-tell phrasing), not ground truth. Don’t use this to accuse anyone of academic misconduct. Use it to audit your own drafts or as one signal among many.

AI Content Detector — FAQ
Free.ai AI Detector inoongorora mazita ezvinyorwa zvema fingerprints eAI generation — yakaderera burstiness, parallel triads, vakasununguka kuchinja, AI-tiudza zvinyorwa se "leverage" / "kushandisa" / "munguva ino yenguva-yenguva" — uye inodzosera 0-100 probability score, per-sentence confidence, uye a labelled list of signals (AI-inoratidzwa kana munhu-inoratidzwa).Pick a text-type pill (general / academic / blog / email / creative / code comments) so that the model applies the right baseline.
Stanford HAI (2023), Vanderbilt (2023), uye University of Maryland (2024) dzidzo zvese zvinoratidza zvisirizvo-positive rates of 5-15% on human writing and false-negative rates above 30% on modern LLMs (GPT-4, Claude 3/4, Gemini). OpenAI yakatidza yavo yepamutemo detector mu 2023 ichiti "yakaderera mwero wechokwadi". Turnitin's yepamutemo documentation inokurudzira kuti yavo AI score haifanire kunge iri chete chikonzero chekutora danho reakademical-integrity.
Three zvakarurama shandisa: (1) Kuongorora yako pachako drafts pamberi kuburitsa — kana yako kunyora scores 85% AI, iwe zvinokwanisika akatarisana ChatGPT uye anofanira rewrite. (2) One chiratidzo pakati pevamwe vashoma pakuvaongorora zvinyorwa — kwete mashoko. (3) Research mukuita-style drift. Illegitimate shandisa: kusungwa vana, gating application basa, flagging emails se "kushaikwa AI". Do not do any of these with ANY detector (paid or free) — the error rates are too high.
GPTZero ndeye $ 10-24 / mo. Originality.ai ndeye $ 14.95 / mo kana $ 0.01 / credit. Copyleaks ndeye $ 10.99 / mo. Turnitin inobatanidza AI detection mu $ 3 + / paper institutional plan. Winston AI ndeye $ 18 / mo. Vose vanoburitsa kuvimbika kwechokwadi kwechokwadi (95% +, 99% +) kuti zvakasiyana neakazvimirira akateedzana edzidzo. Free.ai ndeyemahara uye isu tinotaura zvakajeka: hapana detection inobata 85% kuvimbika pane yakaenzana munhu / AI chinyorwa; vazhinji vanokundikana pasi pe 75% pazvinoitika LLM output.
Tine chinangwa chekuongorora mafingerprints eGPT-3.5, GPT-4, Claude 3/4, Gemini, Llama, uye Mistral. Mamodeli ayo anoburitsa zvakajeka zvakasiyana-siyana zvemitauro (anokumbira neyekuzvimiririra system prompts, tekinoroji tembiricha, kana akagadzirirwa nemunhu kunyora) anowana zvishoma kana kuti ari AI. Mamodeli akagadzirwa nemunhu kuburikidza nechero chirongwa chekuumba munhu (kusanganisira edu pa /text/humanizer/) anowanawo zvishoma.
Pamusoro pe ~ 100 mazwi hapana variance yakakwana kuongorora burstiness (chiratidzo chinosiyana AI's uniformity kubva kune munhu's zvakajairika variation). A two-sentence email inogona kunge iri AI kana nhanho yemunhu mashoko — hapana nzira yekuudza.
Burstiness = kuchinja munguva yekunyora uye kuomarara kwemashoko mubhuku. Vanhu vanonyora mashoko akaomarara: mashoko 40 akaumbwa akatevera mashoko 6 akaumbwa. AI inosarudza mashoko akaomarara, 18-25 mazwi ese, ane kuomarara kwakafanana. Low burstiness + even cadence inoratidza kuti AI ine simba. BUT: zvakajairika zveakademiki uye zvemabhuku epamutemo zvinorevawo kuti mashoko akafanana anowanzoita seanorema, izvo zvinoita kuti nyaya iite.
Best kunyatsonzwisisa muChirungu (vakawanda linguistic tsvakurudzo ndechiEnglish). Decent zviratidzo paSpanish, French, German, Portuguese, Italian. Chinese, Japanese, Arabic basa asi nepamusoro matambudziko rates nokuti AI-tiudza mapepanhau kushandura imperfectly. For low-resource languages, results are essentially random.
Izvi ndezvimwe zvezvikonzero zvakajairika zvekukanganisa kwedetektor. Stanford yakaratidza kuti vanyori vemutauro wechirungu vane mutauro wechirungu vane 61% yenguva vachinzi vanoshandisa AI nekuti nyaya dzavo dziri nechinangwa chekutaura. Kana iwe uchipomerwa kushandisa AI zvichibva pane chero detektor, bvisa pfungwa yako — maturusi aya haasi nechokwadi chakakwana chekutsigira izvi. Screenshot iyi FAQ uye akateedzana ezvinyorwa pamusoro. Kana iwe uchida kuderedza yako score pasina kuchinja pfungwa, /text/humanizer/ inogona kubatsira.

Yeah. POST to /v1/chat/ with the detector system prompt and parse the JSON response in your client. If you're building a product that uses AI detection, READ THE ACADEMIC CAVEATS above — do not build features that make accusations based on detector output alone. Full snippets at /api/.
