## Simplify AI (Chrome Extension)

Simplify AI takes a deliberately minimal approach to the reading-comprehension problem. Instead of opening a sidebar, chatbot panel, or separate workspace, the extension lives entirely in the browser's context menu: select the text that is tripping you up, right-click, choose the simplify action, and the rewritten passage is dropped back into the webpage where the original sat. Because the flow never leaves the page, it suits quick, incidental reading moments — a clause in a contract, a paragraph in a technical RFC, a sentence in a research abstract — rather than long editing sessions.

The tool is published on the Chrome Web Store by Calix Huang, an individual developer, and is offered at no cost. Its footprint is tiny (roughly 14 KB), and the listing states that the developer does not collect or use your data, which matters for people who are wary of sending what they read to a third-party service. The extension is in the Workflow & Planning category and lists English (United States) as its language.

It is worth being realistic about its scope. Simplify AI does one thing, and it does not attempt summarization, translation, tone control, or document-level rewriting. The public listing shows a small install base and a modest rating with only a handful of reviews, and the last visible update dates to 2023, so treat it as a small utility rather than a maintained platform. For occasional "what does this actually mean?" moments it is frictionless and free; for anything heavier you will want a fuller writing assistant.

**Pricing & Plans:** Free. The Chrome Web Store listing shows no subscription, in-app purchase, or paid tier — the extension is simply installed and used at no charge.

- **In-place simplification:** The rewritten text replaces the original selection directly on the webpage, so you keep your reading position and surrounding context.
- **Right-click workflow:** Highlight text, open the context menu, and pick Simplify — there is no popup panel or separate app window to manage.
- **Very small footprint:** The packaged extension is roughly 14 KB, so it adds essentially nothing to browser memory or startup time.
- **No data collection declared:** The developer's Chrome Web Store disclosure states that data is not collected or used, which keeps sensitive reading material local to the browsing session.
- **Free of charge:** No account, trial limit, or payment step stands between installing the extension and using it.

**Strengths:** Completely free with no account or sign-up friction; Rewrite happens inside the page, preserving reading flow and context; Extremely small package with a minimal performance cost; Developer disclosure states no data is collected or sold

**Limitations:** Very narrow scope — simplification only, with no summaries or translation; Public listing shows a small user base and a low average rating; Last visible update is from 2023, so ongoing maintenance is not guaranteed

## StealthWriter

StealthWriter is built around two steps: scan and rewrite. The detector highlights sentences that still read as AI-written, and the humanizer then rewrites the text to smooth those passages out. Because you can run the detector again afterwards, it works as an iterative loop rather than a one-shot button, which makes it more practical for longer articles where only a few paragraphs sound robotic.

The tool targets people who draft with large language models but publish under their own name: bloggers, marketers, copywriters and researchers. Output can be tuned by rewriting level and, at the sentence level, by picking from alternative phrasings. Processing is quick — typically a matter of seconds — and the free tier with 10 daily humanizations and 1,000 words per input is enough to test whether the tone matches your writing style. Paid plans raise both the daily allowance and the maximum input length, which matters if you humanize long-form content regularly.

StealthWriter is a service of AiVantage LLC. On privacy, the company states that text submitted for humanizing or scanning is not stored after processing, not shared with third parties and not used for training. It is best treated as a drafting and polishing assistant: it improves how naturally AI-assisted text reads, but you should still review facts, claims and citations yourself before publishing.

**Pricing & Plans:** Freemium. The free plan costs $0 and includes 10 humanizations and 10 AI scans per day with up to 1,000 words per input. Paid tiers are Starter at $20/month (50/day), Plus at $50/month (150/day), Pro at $100/month (350/day) and Scale at $400/month (2,000/day), each allowing 5,000 words per input, with discounts for annual billing.

- **AI text humanizer:** Rewrites AI-generated drafts with natural phrasing, rhythm and flow, and lets you pick light, medium or aggressive rewriting depending on how much change you want.
- **Built-in AI detector:** Scan text before and after humanizing to see which sentences still look machine-written, with colour-coded sentence-by-sentence highlights.
- **Alternative rewrites per sentence:** Click any sentence to see alternative rewrite options and fine-tune the output until it matches your own voice.
- **Fast batch processing:** Returns humanized text in seconds, with word limits per input ranging from 1,000 words on the free plan up to 5,000 words on paid tiers.
- **Volume-friendly quotas:** Daily allowances scale with your plan, from 10 humanizations a day on the free tier up to 2,000 a day on the Scale plan, for high-volume content workflows.

**Strengths:** Free plan lets you test the humanizer and detector at no cost; Detector and humanizer in one workflow makes quality checking easy; Sentence-level alternative rewrites give fine control over tone; Three rewrite strengths suit different content types

**Limitations:** Monthly quotas are metered per day, so bursty heavy users may hit limits; Humanised text still needs a human read-through for factual accuracy; Result quality varies by language and by how obviously AI-written the source is; No built-in grammar or plagiarism checker beyond the AI detector
