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 [Profile (Markdown)](https://openaitools.app/tool/capsolver.md) ## Sider Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight. Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel. Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base. **Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans. - **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab. - **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material. - **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move. - **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions. - **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits. **Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks **Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans [Profile (Markdown)](https://openaitools.app/tool/sider.md) ## Frequently Asked Questions ### How do CapSolver and Sider compare in monthly traffic?
