## 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

## String Catalog

String Catalog keeps localization inside source control instead of spreading it across spreadsheets and side tools. You connect the repository you already ship from, choose the branch you release from, and String Catalog proposes translation updates as clean diffs that your team reviews and merges like any other change. Native formats stay native: .xcstrings files for Apple platforms and Android strings.xml both round-trip without hand cleanup or one-off scripts.

The product deliberately covers more than raw strings. App Store and Google Play release notes and store listing copy can be prepared in the same workspace, with platform-specific field limits, locale codes, and exportable output that growth teams can ship directly. Tone guidance, protected brand terms, and glossaries travel with every new language so the result sounds like your app rather than a generic machine translation.

Quality control is built into the loop. Reviewers get secure no-login links, suggested fixes appear in review queues, and low-confidence output can be retried before release week. Pricing is deliberately flat across languages: every plan covers up to 40 languages, so cost depends on string volume and workflow needs rather than how many markets you enter.

**Pricing & Plans:** Paid subscription with a monthly or annual option (annual saves about 20%) and one free language to trial. Published plans are Hobby at $15/month, Pro at $45/month, and Business at $75/month, differing mainly by base string-key limits and review features. All plans include up to 40 languages and no per-language charge. Check the site's cost calculator for current figures.

- **Git-native, reviewable workflow:** Connect GitHub, GitLab, or Bitbucket and receive localization updates as pull requests and clean diffs on the branch you release from, so your repository stays the single source of truth.
- **Native format support:** Round-trip .xcstrings for Apple platforms and Android strings.xml without spreadsheet export, broken builds, or custom scripts.
- **Release notes and store metadata:** Translate App Store and Google Play release notes and store listing copy in the same product, with platform-specific field limits and locale handling.
- **Brand voice and glossary controls:** Protect brand terms, add tone guidance, and reuse glossaries so each new locale keeps the product voice users already know.
- **Human review with secure links:** Share no-login review links, inspect suggested fixes in review queues, and bulk-accept edits when a translation needs more than an automatic pass.

**Strengths:** Stays inside the Git workflow teams already trust, with pull requests and clean diffs instead of silent content mutation; Flat pricing across up to 40 languages removes per-locale cost math and makes adding markets predictable; Covers strings, release notes, and store metadata in one product instead of three separate tools; Human review tooling, protected terms, and tone guidance are included rather than bolted on

**Limitations:** Built primarily around iOS and Android app workflows, so web or backend-only projects may find it a tight fit; Review quality features such as shared review links and accuracy monitoring are limited to higher-priced Pro and Business plans; Base string-key ceilings on each tier mean very large apps need to size plans carefully or move up a level
