OmniDetect positions itself as a transparent, multi-engine AI detection aggregator, differentiating through published accuracy metrics and a consensus-based approach. The platform claims to measure and publish its own error rates by language and writing type, using a frozen, inspectable corpus. It offers a free tier with 3 scans per day (first ~300 characters) using ZeroGPT, while paid plans provide full-text analysis via multiple engines selected per language. Pricing is per-word for the engine that actually reads the text, with a 7-Day Pass at $9.99 and Monthly Pro at $29.99. Key features include an AI Writing Coach, Edit & Rescan loop, sentence-level flagged passages with reasons, and privacy controls allowing users to delete their text anytime. The site emphasizes that it does not sell user data and only shares submissions with detection engines. It also provides comparisons against competitors like GPTZero, ZeroGPT, and Turnitin, claiming to include multiple engines for cross-referencing.
Professional reality: If your primary need is deep, specialized plagiarism detection with a vast database of academic sources, dedicated tools like Turnitin or iThenticate remain more comprehensive.
OmniDetect measures its own accuracy and publishes the numbers — by language, by kind of writing, on a corpus you can inspect. The verdict comes with the error rate behind it, so you know exactly how much to trust the result.
Know the real-world reliability of every scan before you rely on it.
OmniDetect shows what it read, which passages mattered, how the method was validated, and where the answer becomes uncertain. You see the analysed scope, method status, evidence, and known limits instead of receiving a black-box score.
Understand exactly why a passage was flagged and decide the next step with confidence.
Your language decides which engine answers, and the choice comes from OmniDetect's own benchmark rather than a vendor pitch. The free plan uses one engine (ZeroGPT), while paid plans measure and select the best engine per language.
Get the most accurate detection for your specific language and writing style.
OmniDetect keeps your submitted text in your history so you can find it again, and you can delete it whenever you want — with or without an account. They do not sell it, and the only outside parties who see it are the detection engines that analyse it.
Maintain full control over your documents and privacy.
When a result confidently flags specific passages, OmniDetect can propose focused rewrites. You review each change and re-check the revised text with the same Word Token balance — turning detection into a guided editing loop.
Improve only what the evidence supports and verify the revision in one seamless flow.
Guest users get a real analysis of the opening of their document (first ~300 characters) with no sign-up and no credit card. A free account covers the whole document and includes 2,500 Word Tokens after sign-up.
Try a genuine detector result and evidence preview before paying anything.
OmniDetect offers simple, transparent pricing. Start free with 3 scans per day (first ~300 characters) using one detection engine. Upgrade to the 7-Day Pass for $9.99 to get 30,000 word tokens, full-text analysis, and an Authenticity Certificate. Monthly Pro at $29.99 provides 100,000 word tokens, full AI Writing Coach, priority support, and scan history. Billing is per word for the engine that reads your text—no subscription to detectors you never use. Delete your text anytime. Don't guess. Know.

Students can paste the opening ~300 characters of an essay into OmniDetect's free scan — no sign-up or credit card required — to get a real detector result with scope and limits, plus a verdict and evidence preview. The free tier includes 3 scans per day, making it ideal for a last-minute check before class.
During exam week or thesis deadlines, the Complete Check Pack ($9.99/7 days) provides 30,000 Word Tokens to analyze up to 50,000 characters. OmniDetect reads the whole document, shows flagged passages and reasons, and offers targeted rewrite candidates you can review — then re-check the revised text with the same balance.
Freelancers and content teams facing a content audit sprint can use the 7-Day Pass to scan multiple documents, identify AI-flagged sections, and generate evidence-guided rewrites. The per-word billing model means you pay only for the engine that reads your text, not a subscription that bills whether you scan or not.
Monthly Pro ($29.99/month) suits content teams, agency editors, and educators with large classes. It includes 100,000 Word Tokens per month, full-text analysis, AI Writing Coach, priority support, scan history & export, and bulk scan support (coming soon). The shared balance supports a continuous check, understand, improve, and re-check loop.
Create a free account on OmniDetect.ai and verify your email to access the dashboard.
Upload a text document, image, or video file to the appropriate detection module to run your first scan.
Review the generated report, noting the confidence scores and highlighted sections for each detection type.
If integrating into workflows, generate an API key from the settings page and review the API documentation for implementation.
For organizations that need to verify content authenticity across multiple formats—text, images, and video—OmniDetect offers a practical consolidation of tools that would otherwise require separate subscriptions and workflows. The platform delivers the most value to teams that already use or are considering tools like Copyscape for plagiarism and want to add AI detection and deepfake analysis without another vendor. The main limitation is that its plagiarism database is not as extensive as dedicated academic tools. For general business use and content moderation, the API and multi-format support make it a worthwhile investment in 2026.
| Decision Area | OmniDetect | When Another Option Wins |
|---|---|---|
| Pricing model | Pay-per-word with a free tier (3 scans/day of ~300 chars) and a $9.99/7-day pass or $29.99/month Pro plan. No subscription required unless you need steady volume. | GPTZero and ZeroGPT offer flat monthly subscriptions that may feel simpler if you scan very large volumes every day and prefer predictable billing. |
| Detection engines | Aggregates multiple top detection engines, chosen per language based on our own benchmark. The free tier uses ZeroGPT; paid plans use the best engine measured for your language. | GPTZero and ZeroGPT each rely on a single proprietary engine, which can be more consistent if you want one familiar verdict rather than an aggregated result. |
| Transparency & accuracy | We publish our own error rate by language and writing type, on an inspectable corpus, and show the method, scope, and limits with every result. | GPTZero and ZeroGPT are more widely known and have larger public track records, which may reassure users who prioritize brand recognition over published self-benchmarks. |
| Revision workflow | Built-in evidence-guided rewriting: flagged passages get targeted rewrite candidates you review, then re-check with the same Word Token balance. | GPTZero and ZeroGPT focus on detection only; if you prefer to handle revisions in a separate tool, their simpler output may be all you need. |
| Privacy & data control | You can delete your text anytime, with or without an account. We don't sell it; only the detection engines that analyze it see it. | GPTZero and ZeroGPT have their own privacy policies; if you already trust their data handling, switching may not be necessary. |

OmniDetect is an AI content detection aggregator that scans your text against multiple top detection engines in one click. The free plan uses 1 engine (ZeroGPT). For paid plans, the detection engines are measured per language, and the choice comes from OmniDetect's own benchmark rather than a vendor pitch.
OmniDetect publishes its own error rate. It measures accuracy by language and by kind of writing, on a corpus you can inspect. The website states: 'Every detector claims accuracy. We measure ours and publish the numbers — by language, by kind of writing, on a corpus you can inspect.' It also shows the analysed scope, method status, evidence and known limits instead of just a mysterious percentage.
Yes, OmniDetect can detect ChatGPT. The FAQ section includes the question 'Can it detect ChatGPT?' and the site offers a dedicated 'Detect ChatGPT' tool. It also lists 'Which AI models can OmniDetect detect?' as a FAQ, and the detection engines are chosen based on the language of your text.
Bottom Line: OmniDetect is a practical investment for any organization that needs to verify content authenticity across text, images, and video in a single platform, but specialized needs in one area may be better served by dedicated tools.
