## CapMonster Cloud

CapMonster Cloud is a cloud-based CAPTCHA solving service aimed at developers, automation engineers, and businesses that need to get past bot-protection challenges at scale. It works through a simple JSON API with official SDKs for languages such as C#, Python, JavaScript, Go, and PHP, and it also offers Chrome and Firefox extensions for solving CAPTCHAs automatically while browsing. Because everything runs in the cloud, there is no software to install and no local processing infrastructure to maintain.

The service covers a wide range of challenge types, including reCAPTCHA v2 and v3 (standard and Enterprise), Cloudflare Turnstile, Cloudflare Bot Challenge, Amazon WAF, GeeTest, Tencent CAPTCHA, Yidun, Text CAPTCHA, and several additional systems. Documented success rates are generally in the 95–99% range depending on type, and typical solving times are a matter of seconds. Prices are structured per 1,000 solved captchas and vary by difficulty, with reCAPTCHA v2 among the cheapest and more complex anti-bot systems costing more.

CapMonster Cloud operates on a prepaid balance model: you top up an account, receive an API key, and each successful solve deducts the corresponding amount. There is no free ongoing plan, though a small test balance is available on request and ZennoPoster users get free test captchas. A refund is offered within a short window if the service does not meet your needs, and there is an affiliate program as well as volume bonuses for high-usage accounts.

**Pricing & Plans:** Paid, prepaid balance model. You pay per 1,000 successfully solved CAPTCHAs, with rates varying by type (roughly $0.04 per 1,000 reCAPTCHA v2 images up to $1.60+ for Tencent/other systems). Volume bonuses up to 15% and a small test balance on request.

- **Broad CAPTCHA coverage:** Supports reCAPTCHA v2/v3 and Enterprise, Cloudflare Turnstile and Bot Challenge, AWS WAF, GeeTest, Tencent CAPTCHA, Yidun, Text CAPTCHA and more.
- **Simple JSON API and SDKs:** Integrate with official libraries for C#, Python, JavaScript, Go, and PHP, or use the API of other services via compatibility.
- **Browser extensions:** Chrome and Firefox extensions detect and solve CAPTCHAs automatically in the background while you browse.
- **Built-in proxies:** Most challenge types can be solved without supplying your own proxies, simplifying setup.
- **Transparent, success-based pricing:** You are charged per solved CAPTCHA, with published rates per 1,000 tasks and volume bonuses.

**Strengths:** Very broad support across popular and niche CAPTCHA types; Simple API with ready-made SDKs for many languages; High reported success rates (95–99%) with fast solving times; Pay only for successfully solved CAPTCHAs; no software to install

**Limitations:** No free ongoing tier; requires prepaying a balance; Costs scale with volume and by difficulty of the CAPTCHA type; Refund window is short (around 3 days after purchase)

## StealthGPT

StealthGPT targets a specific concern: text produced by AI systems can carry recognizable stylistic or statistical patterns that AI detectors flag. Its core humanizer rewrites that text at the sentence level with more natural phrasing, varied structure and a more personal voice, aiming to reduce detectable AI tells while preserving the meaning. A separate AI Detector checks text for AI-generated patterns and returns a 0–100 score without requiring signup, letting you test a draft before and after humanization. Tone options let you shift the register toward Standard, High School, College or PhD writing to match the audience.

The platform has expanded well beyond a single rewrite button. Stealth Writer generates essays and articles with support for in-text citations and references; Stealth Agent runs a guided research-draft-fact-check-humanize workflow in one pass; and the vendor also offers SEO optimization, summarization, grammar checking, text simplification, formalization and paragraph generation. There is a Chat with PDF tool and a Photo to Answers feature, plus a dedicated set of pages for detecting and stripping the invisible watermarks that Anthropic, OpenAI and Google are described as embedding in model output (such as textGrain and SynthID). The vendor publishes claimed benchmark results against detectors including Turnitin and GPTZero.

Distribution is deliberately broad. A Chrome extension (with a human-typing auto-typer) lets you work inside your browser, and there are API, MCP, Zapier and WordPress plugin integrations for programmatic and editorial workflows, plus an AI Detector API and white-label options for businesses. Business plans add shared seats for teams, agencies and developers. StealthGPT is candid about pricing positioning — the site advertises a low-cost trial entry — with higher tiers unlocking more requests and features such as the Stealth Agent and citations.

**Pricing & Plans:** Paid, with a low-cost trial offer advertised (for example a small fee for a few days of access for new users) and free features such as the no-signup AI detector and several free writing tools. Higher tiers unlock more requests, the Stealth Agent, team seats and API/enterprise access. Confirm current rates on the pricing page.

- **AI humanizer:** Rewrites AI-generated text at the sentence level with more natural phrasing, structure and voice to reduce detectable AI patterns.
- **No-signup AI detector:** Check text for AI-generated patterns and receive an instant 0–100 score without creating an account.
- **Stealth Writer and Agent:** Generate long-form essays and articles with citation support, or run a guided research-draft-fact-check-humanize workflow in one flow.
- **Chrome extension with human typing:** Humanize and generate text across websites in Chrome, with a premium auto-typer that types output with natural, human-like keystrokes.
- **Integrations and API:** Connect StealthGPT to Claude, Cursor and other MCP clients, automate via Zapier or n8n, or use the WordPress plugin and developer API.

**Strengths:** Combines humanization, detection, generation and editing in one platform; Free no-signup AI detector lets you evaluate output before paying; Wide integration surface: API, MCP, Zapier, n8n and WordPress; Tone options and long-form writer cover both short and long content

**Limitations:** Vendor-reported detection results are self-published and should be independently verified; Advanced features and higher request limits require higher-priced tiers; Built around evading AI detection, which raises academic-integrity and policy questions
