The 7 Best AI Image Detectors in 2026, Honestly Compared

Full disclosure up front: FakeRadar is our product. That obviously makes us biased — so this comparison plays by two rules. First, every fact below (free limits, prices, features) comes from each vendor’s own site, checked in June 2026. Second, we tell you plainly where a competitor is the better choice, because there are several cases where one is.

If you just want the short version, here’s the table. Details, strengths and honest weaknesses follow.

Quick comparison

Before you pick: three things no vendor likes to say

1. No detector is 100% accurate. Anyone claiming otherwise is marketing to you. Detection accuracy drops on heavily compressed images, screenshots, and outputs from the newest generators. Treat every score as a signal, not a verdict — that principle is core to how FakeRadar reports results, and it should be core to how you read any tool’s output.

2. “AI detection” is at least three different problems. Fully AI-generated images, face swaps pasted into real photos, and deepfake video are detected with different techniques. A tool that’s excellent at one can be blind to another. A face swap is mostly a real photo — whole-image detectors often pass it. (That’s why FakeRadar runs a dedicated per-face detector alongside whole-image analysis.)

3. Free tiers are how you should test. Every tool below has one (except Winston’s time-limited trial). Run the same 5 images through two or three of them before paying anyone — including us.

1. FakeRadar — ours, so judge accordingly

Free: 1 analysis/day with no account, 3/day with a free account. Pro: $9/mo or $89/yr.

We built FakeRadar because most detectors return a single percentage with no explanation. FakeRadar runs a multi-engine ensemble (multiple commercial detection models cross-checked, no single engine gets the final word), locates every face and scores each one separately for face swaps, and — on Pro — shows the actual forensic evidence: ELA heatmaps, FFT spectrum, C2PA Content Credentials and EXIF inspection. Files are deleted after analysis and never used for training.

Honest weaknesses: No browser extension yet. No audio or music detection — Hive and AI or Not cover modalities we don’t. Video analysis is Pro-only and capped at 3 minutes / 50 MB. We’re the newest tool on this list, launched in 2026.

Pick FakeRadar if: you want per-face face-swap analysis, explained results instead of a bare percentage, or forensic evidence you can put in front of an editor.

2. Hive — the enterprise heavyweight

Free: web demo plus a genuinely free Chrome extension. Paid: enterprise API only, custom pricing.

Hive’s models moderate content for major platforms, and its detection covers more modalities than anyone here: images, video, deepfakes, voice clones, AI music and text. Its standout trick is generator attribution — telling you which model likely made the image. The free Chrome extension (right-click any image) is one of the best free utilities in this space.

Honest weaknesses: there is no individual paid plan and no public pricing — if the demo and extension aren’t enough, you’re talking to sales. The web demo is a showcase, not a workflow.

Pick Hive if: you’re a platform or enterprise needing API-scale moderation — or just grab the free extension as a quick first-pass tool. We mean that: it’s good.

3. AI or Not — best multi-modal value

Free: 20 image checks/month. Paid: from $5/mo with a rollover credit system.

AI or Not covers images, video, voice, music and text under one credit system, identifies the likely generator, and has a clean API. At $5/month it’s the cheapest entry into multi-modal detection, and its media references (NYT, Forbes, WSJ) are real.

Honest weaknesses: 20 free images a month is thin for regular use, and the credit math takes a spreadsheet to love. No localized explanation of why an image was flagged.

Pick AI or Not if: you need voice or music detection alongside images without enterprise budgets.

4. Sightengine — the developer’s choice

Free: 2,000 operations/month (max 500/day) — the most generous free API tier here. Paid: from $29/mo.

Sightengine detects outputs from 20+ named generators pixel-by-pixel (no metadata or watermark needed), covers deepfakes and video, and ranked at the top of an independent academic benchmark on 80,000 images. The API and docs are excellent.

Honest weaknesses: it’s built for developers — operation-based pricing and a workflow that assumes you’re integrating, not casually checking. No heatmap or visual explanation of results.

Pick Sightengine if: you’re building detection into your own product. For API integration at scale, it’s probably the strongest option on this list.

5. Illuminarty — region-level detection

Free: basic image and text classification, permanently free. Paid: from $10/mo.

Illuminarty’s localized detection answers a question most tools can’t: which part of this image is AI? Its heatmap highlights suspected regions — genuinely useful for spotting partial edits, and its API tiers are cheap.

Honest weaknesses: no video, audio or dedicated face-swap detection. The site and models update visibly less often than the leaders, which matters in a field where generators change monthly.

Pick Illuminarty if: your main question is “was part of this image edited by AI?” on a budget.

6. Winston AI — forensic depth, no free tier

Free: 14-day trial only (≈4–10 image scans on trial credits). Paid: from $18/mo, or $10/mo billed annually.

Winston comes closest to FakeRadar’s philosophy of showing evidence: its image scans include EXIF/IPTC reading, C2PA verification, ELA and noise analysis with a heatmap. It bundles AI text detection and plagiarism checking, which makes it attractive for educators and publishers.

Honest weaknesses: no permanent free tier — after 14 days you pay. Image scans burn 200–500 credits each, so the real per-image cost is higher than the headline price suggests. No video or audio.

Pick Winston if: you need text + plagiarism + image forensics in one subscription, and you’ll use it enough to justify the price.

7. WasItAI — the budget pick

Free: ~10 images/month, no account needed for basic checks. Paid: from $3.99/mo — the cheapest API entry anywhere ($3.99 buys 100 images/month).

WasItAI does one thing: AI-image checks with a confidence report, in the browser, no install. It’s transparent about limits (its own docs warn accuracy drops on screenshots) and unusually clear on privacy: images are processed once and not retained.

Honest weaknesses: images only — no video, audio, deepfake-specific or face-swap detection. 8 MB file cap. No explanation beyond the confidence score.

Pick WasItAI if: you want the cheapest possible API or a zero-friction quick check.

Also tested

Decopy AI (free 5–10 checks/month, paid from $6.99/mo) is a serviceable no-signup checker bundled with writing tools, but offers no explanation layer and a very low free quota — fine as a second opinion, hard to recommend as a primary tool.

Which one should you actually use?

• Just want a quick free check: WasItAI or Hive’s Chrome extension, with FakeRadar’s free tier when you want the result explained.
• Verifying for publication (journalism/fact-checking): evidence matters more than a score — FakeRadar or Winston. We built a workflow specifically for newsrooms.
• Suspected face swap (dating profile, “proof” photo, group shot): this is the specific case whole-image tools miss — use a per-face detector.
• Building detection into your product: Sightengine first, Hive if you’re enterprise-scale.
• Audio/voice or music checks: AI or Not or Hive — we don’t do audio, they do.
• Region-level “which part is AI”: Illuminarty.

The honest meta-advice: use two tools, not one. Detection is probabilistic; two independent signals agreeing is worth far more than either alone. Every tool here has a free tier — disagreement between them is itself information.
