What is OmniDetect?
OmniDetect is an AI content detector that goes beyond a simple score. It shows you which specific passages in your text read as AI, how strongly they do so, and what you might change. The goal is to give you a transparent answer you can act on, not just a mysterious percentage.
You start by pasting up to 50,000 characters, uploading a file, or scanning a URL. OmniDetect reads the whole text, picks the detection engine based on your language using its own benchmarks, and returns a verdict along with the passages behind it. You can then review the evidence, understand the method and its limits, and if revision is supported, change only what needs attention and re-check the draft.
A free preview analyzes the first 2,000 characters without signup. A free account covers the whole document. The site publishes its measured accuracy, including misses, and keeps your documents in history until you delete them. It does not sell your text, and only the detection engines that analyze it see it.

How to get started with OmniDetect

- If revision is supported, apply the suggested changes and re-check the draft.
Tips for better results with OmniDetect
- Paste the full document into OmniDetect rather than relying on the free 2,000-character preview, since the preview only analyzes the opening and may miss flagged passages later in your text.
- Use OmniDetect's passage-level results to revise only the sections it confidently flags, then re-check the edited draft with the same word token balance to confirm the changes reduced AI detection.
- Set the writer and text type options in OmniDetect before scanning, as the tool adjusts its analysis based on your language and context, which can make the verdict and revision suggestions more accurate for your specific use case.
- Review the evidence OmniDetect shows for each flagged passage, including the method status and known limits, so you understand why it reached its conclusion before deciding whether to apply its suggested rewrites.
OmniDetect pricing
OmniDetect has a free way to start, with paid plans for heavier use. Check omnidetect.ai for current limits and prices.
What to check before you rely on OmniDetect
- Check whether the free account covers the whole document or only the preview, since the website says the free preview analyzes up to 2,000 characters but does not clearly state the full free account limits.
- Verify the pricing for paid plans beyond the freemium tier, as the website labels OmniDetect as freemium but does not list specific prices or what features require payment.
- Confirm the export formats for results, since the website mentions uploading.pdf,.docx, and.txt files but does not state whether you can download or export the analysis report in those or other formats.
