## Kolya_extension

Kolya_extension targets a narrow but interesting problem: watching a YouTube video and wanting a second opinion on whether the speaker is being manipulative, selective with facts, or outright misleading. Rather than asking you to copy a transcript into a chatbot, the extension pulls the transcript, sends it for large language model analysis, and renders the results directly over the video as you watch.

The output is presented as an overlay on the YouTube watch page, with detailed notes attached to the statements made in the video. That in-context placement is the core idea: detection flags sit next to the moment they relate to, instead of arriving as a separate wall of text.

The project is early-stage and clearly a solo effort. The store listing shows version 0.0.1, a tiny 25 MiB package, English-only support, and a small user base. There is no subscription and no separate product website to speak of — the extension is distributed entirely through the Chrome Web Store, and the developer states that no data is collected or sold.

Because the analysis is LLM-generated, it should be treated as a prompt for your own critical thinking rather than a verdict. Models can be confidently wrong about tone, sarcasm, or context, so the overlay is best understood as an attention aid that highlights claims worth double-checking yourself.

**Pricing & Plans:** Free. The extension is offered at no cost through the Chrome Web Store, with no subscription or in-app purchases listed.

- **LLM transcript analysis:** The extension extracts a YouTube video's transcript and runs it through a large language model to look for manipulative framing, unsupported claims, and deceptive statements.
- **On-video overlay:** Findings are drawn on top of the YouTube watch page, so each flag is tied to the moment in the video where the relevant statement occurs.
- **Statement-level detail:** Beyond a simple score, the extension shows notes about individual statements made in the video, giving you something concrete to evaluate.
- **One-click workflow:** There is no transcript copying or prompt engineering: install the extension, open a video, and the analysis appears alongside playback.
- **Privacy-declared, no data resale:** The developer declares that user data is not sold to third parties and is not used for creditworthiness or lending decisions.

**Strengths:** Free to install with no account or payment required; Findings appear in context on the video page rather than in a separate tool; Statement-level detail is more useful than a single opaque trust score; Developer declares no selling of user data to third parties

**Limitations:** Very early release (version 0.0.1) with a very small install base and no ratings; English-language support only; LLM judgments about tone and intent can be wrong, so results need human verification; No dedicated product website, documentation, or support channel beyond a developer email

## 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
