how the
machine works.
how do you tell if an image is AI? you ask more than one detector, and you don't let any of them sound more sure than it has earned. amige. reads your file, routes it to the detectors built for it, weighs what they say, then calibrates the result into a single estimate — likely AI, likely human, or honestly uncertain. a probability, never a proof.
the short version
amige. doesn't trust one detector. it reads a scan, routes it to the detectors suited to it, and cross-checks it against a panel of independent classifiers — then fuses their scores into one verdict with the per-detector breakdown left visible. the case for a panel is empirical: open AI-text detectors that self-report >95% accuracy fall to 60-80% on RAID (ACL 2024), and none tested topped ~80% accuracy at a 5% false-positive rate on adversarial inputs. one classifier collapses on the slice it never trained for; a mixed panel fails on different slices, so combining them is less brittle than betting on any one.
two fast “quick looks” help steer the scan — a routing hint and a novelty radar — but neither one votes on the verdict. and when the panel splits, amige. says so: likely AI, likely human, or uncertain. a probability, never a proof. it's real? or is it?
more than a panel now
a panel is the floor, not the ceiling. amige. now trains its own eye on the marks different generators leave, and uses it to point each scan toward the detectors built to read that kind of content — so the right specialists weigh in, not just whoever's first in line. that hint is a hunch about where to look; it never votes on the verdict.
the fused result is calibrated and capped, held back to uncertain when the panel splits, and the whole thing keeps watch on itself: as new generators appear, amige. relearns and recalibrates rather than drifting out of date. you can watch a single scan move through it, start to finish.
a panel doesn't make detection accurate. it makes it less brittle.
who reads your file
not every detector runs on every scan. amige. starts by narrowing the roster to the ones suited to your file — an image detector for an image, video and deepfake models for a clip, the text classifiers for pasted text — and to what your plan unlocks. the suited set runs cheapest-and-fastest first.
then the panel checks itself. when the first couple of detectors land confidently on the same side, the scan stops there — a clean image doesn't need a tribunal. when they disagree, or all sit in the muddy middle, amige. doesn't force a call: it brings in another detector, looks again, and keeps going up to a ceiling. it never publishes off a single lonely vote.
no secret blend. a custom scan lets you see every detector by name and pick exactly which ones run, and every verdict shows which ones voted. the roster isn't fixed, either — as new detectors prove themselves on independent benchmarks we add them; as others drift, we rotate them out. the method is the constant: independent detectors, cross-checked, with the disagreement left on the table.
two quick looks that never vote
before and during the scan, amige. takes two fast side-glances at your file. neither one gets a vote on whether it's AI.
the first is a routing hint — a quick best-guess at which generator family an image resembles. its only job is to help pick which specialist detector to call if the panel gets stuck. it's a hunch about where to look, not a claim about what the image is — and any detector it pulls in still has to earn its place on the panel's own evidence.
the second is a novelty radar. it asks one narrow question: is this unlike the things we've seen before — a meme, a screenshot, an odd category? it is not a second opinion on AI-vs-real, and it can only ever make amige. more careful. if the radar lights up and the panel isn't already in strong agreement, the verdict holds back to uncertain rather than guess. a novelty flag can talk amige. out of a confident answer; it can never talk it into one.
how we weigh the signals
each detector returns its own probability that the content is AI. amige. blends them into one number — but not as a flat average. detectors that have earned more trust on representative test sets count for more; the weakest are kept on screen as evidence but barred from swinging a verdict on their own. a loud vote from a detector that's wrong a lot shouldn't drag everyone else with it.
the fused number then passes a calibration step, and that step has one rule: it is only ever allowed to soften an overconfident score, never to sharpen one. an honest “maybe” should not get talked up into a “definitely.” if calibration can't run, amige. uses the raw blend and flags the verdict as running in a reduced mode, instead of pretending nothing is missing.
the verdict lands three ways: likely AI, likely human, or uncertain / AI enhanced. the middle band is wide on purpose. and some signals get special handling — a confident deepfake flag is high-precision and low-recall, so amige. lets it carry the verdict instead of averaging it away when a co-detector whiffed. see it on a Tom Cruise deepfake or a Ronaldo & Messi clip.
the model attribution
the panel doesn't stop at AI or not AI. some classifiers return per-model guesses with their own confidence. when a flagged image comes back tagged as looks like Midjourney v6, that's a best guess from a classifier built to recognize a generator family's fingerprint — the frequency-domain and up-sampling artifacts these detectors lean on. that guess is model attribution: a resemblance, never an identification.
amige. canonicalizes model names across the panel (so midjourney_v6, Midjourney v6, and midjourney all collapse into one row), weights each guess by how sure the detector was, and shows you the top few. a flagged gpt-4o image or an AI-written essay both surface their best-guess model next to the verdict. it's a closed set — a detector can only name models it was built to recognize — and the guess never feeds the AI-vs-human score. it's the receipts, not the ruling.
what ‘confidence’ means
the percentage next to a verdict is the probability of the verdict amige. landed on, not a raw AI score. on a likely-AI verdict, 84% is amige.'s confidence it's AI; on a likely-human verdict, 84% is its confidence it's human; on uncertain, you see the raw middle-band score so you can tell where it fell.
two things you'll never see: 0% and 100%. amige. caps every displayed number short of certainty, on purpose. a detector that says it is 100% sure is making a claim we won't make — it's the exact overclaim regulators have gone after. and amige. reports detector disagreement on its own line instead of blending it into the headline, so a likely AI where everyone agrees reads differently from one where a single detector is screaming alone.
when we hold back
uncertain isn't amige. shrugging. it's a decision.
most detectors are built to always answer — to round every hard case up or down. amige. carves out a band where it would rather say “I don't know” than guess, tuned so that across everything it does commit to, it stays under its own budget for wrongly flagging real content as AI. when a scan lands in that band, it abstains. and when the novelty radar says the input is too unfamiliar to stand behind, amige. drops the call rather than promise something it can't keep.
an answer it can't back is worth less than an honest “uncertain.” that's the whole posture: we'll tell you when we're not sure.
where amige. is weak
can a detector catch text that's been through a paraphraser?
mostly no. a NeurIPS 2025 study measured an average 88% drop in true-positive rate across neural, watermark, and zero-shot detectors after a single paraphrasing pass. if a piece of text has been through a humanizer, no detector — amige. included — will catch it reliably. this is the field's limitation, not amige.'s alone.
does amige. flag non-native English as AI?
it can, and that is the field's worst bias. a 2023 Stanford study (Liang et al.) found AI detectors flagged 61-97% of TOEFL essays by non-native English writers as AI-generated. the detectors' makers say they've narrowed that false-positive rate since — their claim, not ours — but short, simple, formal English is still the hardest case for any text classifier. teachers: please don't use a detector score as a sole accusation.
why do edited or screenshotted photos confuse it?
jpeg re-compression, downscaling, screenshot-of-a-screenshot, and partial inpainting all degrade image detection. a real photo screenshotted off social media can read as AI; an AI image that has been recompressed and resized can read as human. the more an image has been through the wringer, the noisier every detector's signal — ours too. AI-denoised photos are a classic false trigger: denoising strips the sensor-noise patterns detectors lean on.
how well does it catch deepfakes in the wild?
open-source deepfake detectors drop roughly 45-50% in AUC moving from academic benchmarks to real social-media content (Deepfake-Eval-2024). commercial detectors are closer but follow the same curve. amige. trusts a high-precision deepfake flag when it fires; the wider gap on novel deepfakes is the open problem of the field, not amige.'s.
is a missing Content Credential proof an image is AI?
no. when an image or video carries C2PA provenance metadata, amige. reads it and surfaces what it says. but fewer than 1% of news media and almost no user-generated content carries it today, so its absence proves nothing. C2PA is the right long-term answer; adoption is just sparse.
why does amige. reject very short text?
because it is too thin a signal to be honest about. below the floor we set for the active text models, a verdict would be a guess dressed up as a measurement — so amige. declines it before it costs you a credit and a misleading answer.
how to use a verdict
treat the verdict as a signal, not a sentence. a likely AI at 92% with every classifier agreeing is strong evidence. the same verdict with one detector at 95% and another at 51% is two stories at once — and the per-detector breakdown is the part you should read.
ask amige.'s answer what you'd ask a human reviewer: does the model attribution match what you'd expect? is the confidence agreement, or one classifier screaming alone? did it abstain — and is the content the kind this tech handles well (a clean diffusion image, long English text) or badly (a screenshot, an ESL essay, paraphrased chatbot output)? if you want to see how amige. compares, the breakdown is where to start. image or amige?
questions
what kinds of content can amige. check?
images, videos, text, and links to social posts (tiktok, instagram, threads, x, facebook, youtube). drop the file, paste the link, paste the text. text under our minimum length gets rejected before it eats a credit — too thin a signal to be honest about.
does amige. run every detector on every scan?
no. each scan goes to a suited subset — image detectors for an image, video and deepfake models for a clip, text classifiers for text — ordered fastest-first. when the first couple of detectors land confidently on the same side, the scan stops there; when they disagree, amige. brings in another and looks again, up to a ceiling. you can see exactly which detectors ran on every verdict.
what are the “quick looks”, and do they decide the verdict?
no — and that's the point. amige. takes two fast side-glances at an image: a routing hint (a guess at which generator family it resembles, used only to pick which specialist detector to call) and a novelty radar (a check for whether the image is unusual, like a meme or a screenshot). neither votes on AI-vs-human. the novelty radar can only make amige. more cautious — it can push a verdict to uncertain, never toward AI.
why does amige. sometimes refuse to give a verdict?
because a confident wrong answer is worse than an honest “uncertain.” amige. holds a band where it would rather abstain than guess, tuned to stay under its own budget for wrongly flagging real content as AI. if a scan lands in that band, or the content is too unusual to stand behind, you get uncertain on purpose — not a forced coin-flip.
why is the confidence never 100%?
by design. every displayed number is capped short of 0% and 100%. a verdict that reads as absolute certainty is a claim we won't make about a probabilistic estimate — and it's the exact kind of overclaim regulators have penalized. the cap never changes which way a verdict falls, only how loud it's allowed to sound.
is amige. free?
yes. 3 image or text scans per day on the free tier, no card required. the Pass tier ($9/month) lifts the cap and unlocks video; pay-as-you-go scan packs never expire.
does amige. train on my uploads?
no. uploads sit in private storage, get scanned, and stay yours. they are not used to train any model, ours or anyone else's. you can delete any individual scan from /history, and you can export everything we hold for you as a single JSON file.
does amige. detect deepfakes?
yes. when a video or image carries deepfake-specific signals (face-swap artifacts, identity-mismatch fingerprints), the verdict flips to DEEPFAKE / AI FACE-SWAP DETECTED in coral. it is a high-precision signal — when it fires, it means something. the per-detector breakdown shows you which classifier raised it and how loudly.
what does the “AI enhanced” verdict mean?
verdicts split three ways: likely AI, likely human, or uncertain / AI enhanced. the middle band catches the ambiguous cases — when the panel disagrees, or when a real image has been retouched in parts (generative fill, magic eraser, partial inpainting). the per-detector breakdown is the part to read when the verdict lands in the middle.
what if amige. flags my own work as AI?
it happens. short, formal, formulaic prose is the hardest case for any text classifier, and post-processed photos (jpeg re-compression, screenshots of screenshots, heavy denoising) reliably confuse image detectors. check the per-detector breakdown: an uncertain with three detectors near 50% reads very differently from a confident likely AI with every detector agreeing. share the permalink with the breakdown visible.
