## search-tune

search-tune sits between you and Google and quietly upgrades the query you are about to run. The workflow is deliberately minimal: type your natural phrasing into the Google search bar, tap the '/' key twice, and the extension sends your text through GPT to produce a more effective set of search terms. There are no menus to learn and no dashboards to manage.

The extension is especially useful if English is not your first language or if you frequently translate an idea from Chinese into an English query. It accepts Chinese input and returns English search terms, which helps surface English-language sources that a literal translation might miss. Because it works inside the native search bar, the change in behaviour is small enough to become a habit quickly.

It is published by an independent developer, free to install, and the developer has stated that it does not collect or use your data. It is a narrow, single-purpose utility rather than a full research suite, which keeps the interface simple but also limits what it can do beyond query rewriting.

**Pricing & Plans:** Free to install and use from the Chrome Web Store; no paid tiers are advertised.

- **Double-slash trigger:** Type your query, press '/' twice in the Google search bar, and get a refined search term.
- **GPT-powered rewriting:** Uses GPT to analyze and rework your phrasing into a more effective Google query.
- **Chinese to English search:** Enter your query in Chinese and receive optimized English search terms.
- **Works inline with Google:** Lives in the existing Google search bar instead of adding a separate interface.
- **No data collection:** The developer declares that no data is collected or used.

**Strengths:** Free and extremely quick to set up; Minimal, keyboard-driven workflow inside the Google search bar; Useful for Chinese speakers searching English content; Developer states that no data is collected

**Limitations:** Very small user base and no ratings, so community feedback is thin; Only rewrites queries; it does not provide research or results analysis; Requires a working GPT-backed service behind the scenes

## WriteHuman

WriteHuman is an AI humanizer built for people who write with large language models and want the output to read like a person wrote it. The workflow is deliberately short: copy AI-generated text from ChatGPT, Claude, Gemini, Grok, DeepSeek or another assistant, paste it into the humanizer, and click Write Human. Within seconds the tool returns a rewrite that varies sentence length, swaps rigid phrasing for everyday word choices and restructures prose, while keeping the original facts and claims intact.

The product is more than a single rewriter. A built-in detector scores drafts sentence by sentence with an AI probability, flagging anything above roughly 60% as likely machine-written and anything under 40% as reading human, so you can see exactly which lines need another pass. There is also an AI image detector, a word counter, a Chrome extension that works in any tab, mobile apps, and an MCP server so AI agents can call the humanizer directly. This makes WriteHuman usable for long-form articles, marketing copy, client deliverables, business communications and newsletters rather than just short snippets.

WriteHuman operates a freemium model. The free tier gives 3 humanization requests a month at up to 250 words each with basic quality, while Basic, Pro and Ultra plans raise request limits, word caps, output variations and detector checks, and add priority support. A separate API tier is priced per word for teams building on top of the engine. WriteHuman describes itself as an independent tool and is not affiliated with the detectors it is compared against; results depend on how those third-party detectors score text at any given moment.

**Pricing & Plans:** Freemium. The free plan allows 3 humanizer requests/month up to 250 words with basic quality and 10 detector checks. Paid plans bill annually at $12/mo (Basic, 80 requests), $19/mo (Pro, 200 requests, MCP access) and $39/mo (Ultra, unlimited requests, 1,000 MCP calls/mo); monthly prices are $20/$29/$59. A word-priced REST API is sold separately. Cancel anytime and switch plans freely.

- **AI humanizer:** Paste text from any AI writing tool and get back a rewrite with more natural rhythm, varied sentence lengths and less formulaic word choices, while keeping the original meaning intact.
- **Built-in AI detector:** Score your draft sentence by sentence so you can see which lines read as human, which are borderline, and which still read as machine-written before you publish.
- **AI image detector and word counter:** Check whether an image looks AI-generated, alongside a word and character counter for quick draft checks.
- **Chrome extension, mobile apps and MCP:** Humanize and fix writing in any browser tab with the Chrome extension, and use mobile apps plus MCP access to reach the same engine from your phone or your AI agents.
- **Developer API:** A REST endpoint with word-based pricing, 40+ language support and code examples in JavaScript, Python and cURL for automated pipelines.

**Strengths:** Very short workflow: paste text, click once, get a publishable rewrite; Sentence-level AI probability scores make it easy to spot problem lines; Broad integration surface as a Chrome extension, mobile app, API and MCP server; Covers 40+ languages for multilingual content teams

**Limitations:** AI-detector outcomes are never guaranteed, since detectors keep updating their models; Free tier is only 3 requests per month with a 250-word cap and basic quality; Output quality varies by language and by how formulaic the source text is; Unlimited plans still cap the words per single request
