What SlopTotal is
SlopTotal analyzes pasted text or a public URL with 23 AI detection engines and displays each engine’s vote alongside a calibrated score. For URLs, it extracts article content automatically. The engines run in parallel and use neural classifiers, statistical tests, and linguistic heuristics; results appear as each one finishes, and weighted votes contribute to the final score. A separate Site check reports whether a site appears to have been built with an AI app builder. The Free plan costs nothing, requires no account or credit card, and has no scan limits. It includes API access and batch scanning, but no report exports. SlopTotal processes submitted text on its own servers rather than sending it to third-party detection APIs or LLM providers. Reports are automatically deleted after 30 days. The detection backend is open source and can be self-hosted, and a Chrome extension can mark AI-looking results in Google Search and LinkedIn. The maker warns that scores are unreliable below about 80 words and settle at roughly 200 words and above; scores should not decide grades, hiring, or publication without human review.

The full review of SlopTotal
Overview
SlopTotal is an AI-content screening service that checks pasted text and public URLs, with browser and self-hosting options. It suits people who want multiple detector signals without per-scan charges. Its scores can guide further review, but should not stand alone as a judgment.
Key features
SlopTotal runs 23 detection engines in parallel, spanning neural classifiers, statistical tests and linguistic heuristics. It combines their weighted votes into a calibrated score and streams results as each engine finishes, with each vote visible. That transparency makes it easier to see when signals differ, though a consensus score still cannot establish authorship.
Users can paste text or submit a public URL; the service extracts article content from the URL. Site check reports whether a site appears to have been built with an AI app builder. The Chrome extension marks AI-looking results in Google Search and LinkedIn, making it more useful for browsing-based screening than a text box alone.
Submitted text is processed on SlopTotal’s own servers rather than sent to third-party detection APIs or LLM providers. Reports are automatically deleted after 30 days, and the privacy policy says the service uses no cookies, analytics trackers or fingerprinting. Its open-source detection backend can be self-hosted on the user’s hardware, an advantage for users who want to run it independently.
Short text is a meaningful limitation: SlopTotal’s own guidance says scores are unreliable below about 80 words and settle at roughly 200 words and above. That makes it a poor basis for judging brief answers or snippets. The maker also cautions against using a score by itself to decide a grade, hire or publication; in consequential settings, treat it as a lead for human review.
Pricing
The Free plan costs nothing, requires no account or credit card, and has no scan limits. It includes API access and batch scanning, but no report exports. That combination is unusually accommodating for repeated checks and integrations, while the lack of exports may frustrate users who need to retain or circulate formal reports. There is no free trial because the plan is free; no paid tier is given.
Platforms
SlopTotal supports API, browser extension, Linux, macOS, self-hosting, web and Windows. The Chrome extension is specifically described as marking results in Google Search and LinkedIn. The broad platform range and open-source backend make it flexible, although self-hosting is an option rather than a substitute for understanding the score’s limits.
Who it's for
Editors, educators, SEO teams, recruiters, teachers, law firms and e-commerce operations are among the maker’s suggested users. It is best suited to teams screening longer passages or articles who can follow up on suspicious results. Those deciding grades, hiring or publication outcomes should use other evidence and human judgment, not a detector score as the deciding factor.
Pros and cons
- Pros: 23 visible engine votes provide more context than a single opaque score.
- Pros: Unlimited free scans, batch scanning and API access support repeated or workflow-based checks without a per-scan bill.
- Pros: Own-server processing, 30-day report deletion, and an open-source self-hosting option address different privacy preferences.
- Cons: Results on texts under about 80 words are unreliable, limiting use on short submissions.
- Cons: There are no report exports, so users needing portable records will have to work around that gap.
- Cons: The score is evidence rather than a verdict, making SlopTotal unsuitable as the sole basis for high-stakes decisions.
Alternatives
Compare AI Content Detection Software if you want to consider the wider category before choosing a checker.
Choose TrustOriginality.ai instead if you want its Android or iOS access; its free plan allows one text analysis per month, unlike SlopTotal’s unlimited scans.
Trinka is another option for readers comparing writing software with API, extension, desktop and self-hosted platform support.
Choose Ahrefs if your priority is its site data and limited Site Explorer and Site Audit access on the free plan, rather than SlopTotal’s multi-engine text screening.
AI Detect is an alternative for users who want local use on desktop or self-hosted systems, with no API key or usage limits.
Corrector.app is better suited to free grammar and spelling checks, with no account registration and a 15,000-character input limit.
GPTZero may suit users who prefer a monthly free allowance of 10,000 words and 50,000 characters, or want to compare its paid tiers.
AI or Not is an option for users seeking a free plan that includes AI image checks as well as text detection credits.
Hive AI-Generated Content Detection may fit developers looking for access to multiple Hive models, though its free credits require adding a payment method.
Verdict
SlopTotal is a strong fit for editors and teams who want unrestricted access to several detection signals, visible engine votes and the option to self-host. Its central advantage is breadth without a scan cap; its central drawback is that scores are uncertain on short text and cannot settle consequential decisions. Choose it as a screening aid, not an authorship judge.
