## CapSolver

CapSolver is a CAPTCHA recognition service built for developers, data teams, and automation engineers who need to get past anti-bot challenges programmatically. Rather than relying on manual solving, it pairs AI image recognition and OCR models with solving infrastructure to return valid tokens for common challenge types such as reCAPTCHA, hCaptcha, and Cloudflare Turnstile.

Integration is designed to be low-friction: you send a request describing the target challenge, and the service responds with a solution token you can inject into your workflow. Alongside the HTTP API, browser extensions and automation-tool integrations let teams embed solving into scraping pipelines, QA suites, and browsing sessions without rebuilding their stack.

Access is credit-based. New users get a free trial to validate accuracy and integration, then top up a balance that is consumed per solve, so cost tracks actual volume. Because solving reliability varies by challenge type and target site, teams typically monitor success rates and fall back to alternatives when a specific deployment proves difficult.

**Pricing & Plans:** Free trial available for evaluation, followed by pay-as-you-go credit top-ups consumed per successful solve. Exact rates depend on the challenge type and volume, so check the dashboard for current pricing.

- **Broad challenge coverage:** Handles popular challenge types including reCAPTCHA, hCaptcha, Cloudflare Turnstile, and image or OCR-based recognition.
- **Simple API integration:** A straightforward HTTP API lets developers submit challenges and receive solution tokens programmatically.
- **Browser extensions:** Extensions and browser-automation hooks make it easier to solve challenges inside real browsing sessions.
- **AI and OCR recognition:** Image recognition plus OCR models are applied to text and picture CAPTCHAs as well as interactive puzzles.
- **Pay-as-you-go pricing:** Credits are consumed per solve, so costs scale with actual usage rather than a fixed seat license.

**Strengths:** Handles a wide range of CAPTCHA types through one API; Free trial lets teams validate accuracy before paying; Pay-as-you-go credits keep costs proportional to usage; Extensions and automation integrations speed up setup

## 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
