## Liars.AI

Liars.AI markets itself as the first AI-powered lie detector app. It is deliberately framed as a fun, exploratory tool: you record or upload a video of someone speaking, and the system scans for cues that may suggest deception. Beginners and casual users can point, shoot, and record straight from the phone browser without installing anything, then get an analysis within seconds.

Under the hood, Liars.AI uses a proprietary analysis pipeline trained to interpret facial expressions, body language, and tone of voice as indicators of deception. The team says it keeps improving the model with better datasets and reinforcement learning from human feedback, using ratings from users to refine results. The site also states the insights are inspired by widely discussed lie-detection theories and should be treated as informative and thought-provoking rather than definitive.

The service is web-first and works on any device, including iPhones and iPads through the browser, with an iOS app described as in development. The platform states it has already analyzed more than 10,000 videos and offers an affiliate program paying 20% commission. Payments run through Stripe, results can be shared by link, and videos are kept private unless you choose to share a specific analysis.

**Pricing & Plans:** Liars.AI is a paid service with a free trial path: invite three friends and, if all three sign up, you receive 15 seconds of free video analysis. Full pricing is shown in the sign-up pricing table. Payments are handled by Stripe and include major cards plus many regional methods, though PayPal and cryptocurrency are not accepted. Subscriptions can be upgraded, downgraded, or cancelled anytime; refunds are generally not offered because analysis incurs GPU costs immediately.

- **Video-based truth analysis:** Record a clip in the browser or upload an existing file, and the pipeline returns a plain-language summary of whether the speaker appears to be lying.
- **Multi-signal cue detection:** The platform reads subtle cues from facial expressions, body language, and vocal tone to flag moments that may signal deception.
- **Readable result reports:** Get a clear, easy-to-understand breakdown of the analysis rather than raw data, so you can interpret the outcome at a glance.
- **Shareable analysis links:** Share any analysis result with a link, or download the video and result to pass along in whatever channel you prefer.
- **Privacy-first by default:** Uploaded clips stay private by default and are only made public if you explicitly choose to share that specific analysis.
- **Affiliate program:** Join the affiliate program and earn a 20% commission on payments from customers you refer to the platform.

**Strengths:** Simple browser workflow — shoot or upload a video and get an analysis in seconds; No install required since it runs on any device through the web browser; Clear, easy-to-understand summaries rather than raw technical output; Analysis results can be shared with a link or downloaded freely

**Limitations:** Deception detection from video cues is not scientifically reliable and results are explicitly framed as informative rather than definitive; No PayPal or cryptocurrency payments accepted; No refunds offered once analysis runs, since GPU costs are already incurred; Videos of minors are strictly prohibited, limiting some use cases

## Scribbr

Scribbr was built around a simple promise: help students submit work they feel confident about. The core of the service is human proofreading and editing, delivered by a hand-picked pool of academic editors who go through an in-house training programme before they are allowed to take orders. Documents are returned with tracked changes, in-text comments and a short personal letter explaining the reasoning behind the main edits.

Alongside the human service, Scribbr offers a growing library of AI writing tools. The Academic Check bundles together grammar and language review, citation checking, plagiarism scanning and AI-content detection into a single upload, which is convenient when you want one pass over an entire paper rather than juggling separate tools. Individual utilities such as the citation generator for APA, MLA, Chicago, AMA, IEEE and ACS, the paraphrasing tool and the text summarizer can be used on their own without paying for an edit.

The platform also maintains a large free knowledge base of academic writing guides that has become one of the more popular ways students discover the brand. Pricing depends heavily on document length, chosen turnaround time and add-on checks, so the practical way to get a number is to upload a file and select services in the order flow.

**Pricing & Plans:** Freemium model. Free tools include the citation generator, grammar checker and summarizer. Human proofreading and editing, the plagiarism checker, AI detector, AI proofreader and Academic Check are paid per document, with the final price depending on page count, delivery speed and any add-on checks such as structure or clarity review.

- **Human proofreading and editing:** A vetted academic editor reviews your paper within hours and returns tracked changes, comments and an explanation letter.
- **Plagiarism checker:** Scans your document against a large web and publication database to surface potentially unoriginal passages before submission.
- **AI detector and AI humanizer:** Flags text likely generated by large language models and offers a rewriting mode aimed at making AI-assisted drafts sound more natural.
- **Citation generator:** Creates and verifies references in APA, MLA, Chicago, AMA, IEEE and ACS styles from a URL, DOI or title search.
- **Academic Check bundle:** Runs grammar, citations, clarity, plagiarism and AI-detection checks in a single upload of the whole document.

**Strengths:** Combines human editors with AI tools rather than relying on one alone; Strong editorial vetting process and a large pool of academic specialists; Free citation generator and knowledge base are genuinely useful on their own; Transparent turnaround options starting from a few hours

**Limitations:** Paid services are priced per document, which adds up for long theses; AI detector verdicts can still be disputed by institutions; Some premium checks require you to buy them alongside an editing order
