## Mercor

Mercor started as an AI recruiting marketplace that used machine learning to match candidates with remote jobs faster than traditional hiring. The platform interviews and vets applicants automatically, then routes matched professionals to short-term and long-term engagements that range from software and data work to specialist expert tasks.

Over time Mercor expanded well beyond recruiting. It now positions itself around "organizing human intelligence to power the AI economy," running interfaces for frontier research, AI benchmarks and AI-agent training at scale. Its enterprise arm builds industry benchmarks with partner organizations, sells human evaluation capacity to frontier labs, and lets businesses turn their own workflow data into a new revenue stream through anonymized licensing.

Mercor reports hundreds of thousands of roles created, an average contracted expert rate around $90 per hour and millions in daily payouts. It has raised significant venture funding and works with leading AI labs and large enterprises, serving both experts looking for flexible paid work and companies that need human data, evaluations or AI-ready talent.

**Pricing & Plans:** Free to sign up for experts; Mercor takes no fee from talent. Enterprises and AI labs pay custom, quote-based rates for data, benchmarking and evaluation services — contact sales for details.

- **AI-powered talent matching:** Machine-learning models screen and match candidates to remote roles in hours rather than weeks, based on skills, experience and availability.
- **Automated expert vetting:** AI-driven interviews and assessments validate professional expertise before experts are surfaced to hiring partners.
- **Paid expert engagements:** Experts work on flexible, remote projects with rates reported to average around $90 per hour and fast, recurring payouts.
- **Industry benchmark building:** Mercor collaborates with enterprises to design benchmarks such as legal, accounting and software-engineering evaluations for AI agents.
- **Enterprise data monetization:** Businesses can license anonymized workflow data to Mercor, with automated masking of sensitive identifiers and full control over what is shared.

**Strengths:** Fast, AI-driven matching that shortens time-to-hire dramatically; High reported pay rates and quick, frequent payouts for experts; Broad scope beyond recruiting — benchmarks, evals and data monetization; Works with major AI labs and enterprises, signaling strong credibility

**Limitations:** Enterprise pricing is quote-only, so costs are not transparent upfront; Work is project-based and may be irregular for some experts; Availability depends on demand from AI labs and enterprise partners

## Underpin

Underpin is a lightweight Chrome extension built for people who apply to many jobs and lose track of where they have already applied. Rather than making you log every submission by hand, it watches the pages you use to apply and records each application as it happens, building a personal history of your job search without extra spreadsheets.

The extension's headline feature is duplicate detection. Because it remembers your previous applications, Underpin can warn you when a current listing matches a role or company you have already applied to, so you avoid wasting effort and avoid looking repetitive to recruiters. It also helps you focus on genuinely new openings instead of re-treading familiar ones.

Underpin runs in the background as a popup-driven extension and keeps your data private, with the developer declaring no collection or sale of user data. It is distributed through the Chrome Web Store as a free-to-install tool, making it an easy addition to an existing job-search workflow.

**Pricing & Plans:** Free to install from the Chrome Web Store, with the developer offering it on a freemium basis for extended use.

- **Automatic application tracking:** Detects job application pages as you use them and records each submission automatically, so you do not have to log anything manually.
- **Duplicate application alerts:** Compares new listings against your history and warns you when you are about to apply to a role you have already submitted to.
- **Focus on new openings:** Keeps a running record of where you have applied so you can concentrate your time on fresh opportunities rather than repeats.
- **Popup workflow:** Access your tracked applications through a simple extension popup that opens alongside the site you are already browsing.
- **Privacy-minded design:** The developer states that data is not collected, sold, or shared for unrelated purposes.

**Strengths:** Removes the manual burden of logging job applications; Duplicate-detection warnings directly save time and effort; Free to install as a Chrome extension; Developer declares no data collection or selling

**Limitations:** Only available as a Chrome browser extension; Provides tracking and alerts rather than end-to-end application automation
