## Browserless

Browserless gives developers a browser that already works in production instead of one that crashes, leaks memory, or gets blocked. Rather than running your own fleet of Chrome processes, you connect with a few lines of code over the WebSocket endpoint using Puppeteer or Playwright, or call task-specific REST endpoints for scraping, screenshots, PDFs, and downloads. The platform handles Chrome version upgrades, auto-scaling through traffic spikes, retries, and session queues so your automation code stays unchanged.

Its modern focus is AI agents. A built-in MCP server exposes search, scrape, and crawl tools that Claude, Cursor, or any MCP client can call directly, while Authenticated Profiles let an agent log in once and stay signed in across runs instead of hitting login walls or hard-coding credentials. Stealth fingerprints, CAPTCHA solving, and residential/datacenter proxies are included so agents that work in a demo also work against anti-bot-heavy production sites.

You can run Browserless as a fully managed cloud, a managed private cloud, or on your own hardware, using the same API in every case. The free tier covers 1,000 units per month with two concurrent browsers and no credit card; paid plans and enterprise agreements add concurrency, dedicated workers, SLAs, and compliance coverage such as SOC 2 Type II and HIPAA BAAs.

**Pricing & Plans:** Freemium: a free plan includes about 1,000 units per month with 2 concurrent browsers and no credit card. Paid plans scale units and concurrency, and self-hosted/enterprise options are quoted on request.

- **Puppeteer & Playwright endpoints:** Swap launch() for connect() and point your existing Puppeteer or Playwright scripts at a managed cloud browser — no rewrite required.
- **MCP server & browser agent:** Give MCP clients like Claude or Cursor ready-made search, scrape, and crawl tools, or run Browserless's own stateful agent for multi-step tasks.
- **Stealth, CAPTCHA & proxies:** Automatic anti-bot bypass, built-in CAPTCHA solving, and residential or datacenter proxy rotation to get through blocked targets.
- **Authenticated Profiles:** Log in one time and reuse the session across every run, so agents start signed in without credentials baked into your code.
- **Screenshot, PDF & debug APIs:** Generate pixel-perfect screenshots and PDFs from any URL, with a live debugger, request metrics, and worker health in the dashboard.

**Strengths:** One-line migration from self-hosted Puppeteer/Playwright to managed browsers; Built-in stealth, CAPTCHA solving, and proxies remove the hardest scraping work; Same API across cloud, managed cloud, and self-hosted deployments; Strong fit for AI agents via MCP server and persistent authenticated sessions

**Limitations:** Concurrency and unit quotas mean heavy scrapers can hit plan limits quickly; Pricing scales with usage, so high-volume workloads need cost planning; Advanced enterprise controls like dedicated GPUs and region pinning require sales contact

## Undetectable AI

Undetectable AI focuses on a single practical problem: content that sounds machine-made can be penalized, flagged or distrusted. The platform's detector highlights which sentences a scanner would most likely mark as AI-generated, showing percentages before the humanizer even runs. Once flagged, the humanizer rewrites those segments with varied sentence structure, richer vocabulary and adjusted tone, aiming to keep the original meaning intact while producing writing that reads naturally.

Beyond the core text tools, the product range has expanded into media forensics. There are detectors for AI-generated images, voice, video and deepfakes, plus specialty utilities such as a fake PDF detector, a receipt checker and other document-verification tools. A Chrome extension brings detection and rewriting into Gmail, Google Docs and any other page you are typing on, and an API is offered for teams that want the humanizer embedded in their own workflows.

The platform reports more than 24 million users and supports 50+ languages, though English yields the most accurate results. Business Solutions add stricter data-retention controls, white-labeling and non-expiring credit packs for higher-volume clients. A free tier is available with limited words, and the vendor advertises a money-back guarantee when humanized output is still flagged.

**Pricing & Plans:** Freemium. A free trial covers a limited number of words (currently 250). Paid monthly plans start around $9.99 for 10K words and scale to roughly $42.50 for 50K words, while annual billing discounts those rates by about half (roughly $5.00-$21.25 per month). Custom business tiers add non-expiring credits, redistribution rights and priority support.

- **AI Detector:** Scans up to 5,000 words at a time and highlights the specific sentences most likely to be flagged as machine-written, so you can see your text the way a detector sees it.
- **AI Humanizer:** Rewrites AI-flagged passages with different sentence rhythms, vocabulary and tone, keeping your meaning while making the prose read like human writing.
- **Media authenticity checks:** Detectors for AI images, voice recordings, video and deepfakes, plus specialty document tools for checking whether a PDF or screenshot has been manipulated.
- **Chrome extension:** Detect and humanize directly inside Gmail, Google Docs or any web page without switching tabs.
- **API and business options:** An API lets teams plug humanizing into existing pipelines, while business plans offer white-labeling, higher volumes and non-expiring credits.

**Strengths:** Detector and humanizer live in one workflow, so you can flag and fix text without switching apps; Wide language coverage (50+ languages) with strong English accuracy; Extra media tools (image, audio, video, deepfake, fake PDF) beyond plain text; Chrome extension makes it usable inside the tools people already write in

**Limitations:** Detector results are probabilistic and can disagree with other detectors or with human reviewers; Free tier caps out at roughly 250 words, so any real workload needs a subscription; Word limits still apply even on paid tiers, so heavy publishing volumes require enterprise pricing; Humanized output sometimes needs a light manual edit to preserve nuance and technical accuracy
