## clickworker

clickworker is a data-services company that turns business data projects into structured microtasks carried out by a global crowd. Companies define a task — collecting shelf photos, labeling images, verifying addresses, running surveys, testing an app — and clickworker recruits, briefs and quality-checks the workers who complete it. The crowd numbers more than 10 million registered freelancers across 136 countries.

The core offering is AI training data: image, video, audio and text datasets with human-powered labeling, annotation and validation, delivered in cooperation with parent company LXT. Around that sit adjacent services such as surveys with a verified respondent pool, store checks and display audits at the point of sale, tagging and sentiment analysis, crowdtesting for websites and apps, list building, and SEO copywriting.

Engagements can be self-service, fully managed or delivered through an API and iframe integration. clickworker emphasizes its 20+ years of microtask experience, ISO 27001 certification and GDPR compliance, and works with clients such as OTTO, Bosch and Tennis-Point on large-scale data collection and evaluation projects.

**Pricing & Plans:** clickworker quotes project prices rather than publishing list rates; cost depends on task type, volume, target geography and quality requirements. A self-service option and a managed service are both available, and Clickworkers are paid per completed task.

- **AI training data at scale:** Custom image, video, audio and text datasets with human labeling, annotation and validation, delivered with parent company LXT.
- **Global crowd of 10M+ Clickworkers:** Registered freelancers in 136 countries fill microtasks through web, Android and iOS apps, with flexible scaling up or down.
- **Survey and market research services:** An all-in-one survey tool plus access to a verified respondent pool for external studies and targeted insights.
- **Store checks and crowdtesting:** Real-time point-of-sale data collection, display audits, mystery checks, and usability testing for websites, apps and games.
- **Managed, self-service and API delivery:** Choose a fully managed project, run tasks yourself, or integrate crowd workflows through API and iframe form options.

**Strengths:** Enormous, geographically diverse crowd that can scale projects up or down quickly; Covers the full data pipeline from collection through annotation and validation; ISO 27001 certified and GDPR compliant with documented quality assurance; Multiple engagement models: managed, self-service, API and iframe

**Limitations:** Pricing is quote-based, so smaller projects may struggle to get transparent costs; Quality depends on task design and briefing, which the client must invest effort in; Not a plug-and-play AI API — it is a services business requiring project scoping

## Face Search

Face Search tackles a specific problem that ordinary reverse image search cannot solve. Google Lens, Yandex Images and similar tools match pixels and near-duplicates, so they fail when the subject appears in a different outfit, a later year, or a crop that never existed online before. Face Search instead analyzes facial geometry — eyes, nose, mouth, jawline — to compare one face against images of the same person in entirely different photos.

The flow is deliberately simple. You upload a clear front-facing portrait, the system detects and embeds the face, queries a public-image index, and returns ranked candidate sources with similarity scores and context. A guest preview shows whether matches likely exist before you pay; full unlocked results, direct source links and social-platform coverage come after checkout. The site is explicit that its paid searches are executed through the FaceCheck.id index and that the product's own value is the upload experience, credit billing and results review.

Billing is credit-based rather than subscription-based. Packs are one-time purchases, credits never expire, and there is a 30-day money-back guarantee, so occasional users are not locked into a recurring charge. The team also publishes methodology and ethics pages, and repeatedly warns that a similarity score is a lead to investigate, not proof of identity.

**Pricing & Plans:** Freemium. A free guest upload produces a preview so you can judge whether matches likely exist. Full results require one-time credit packs: Essential $7 for 2 searches, Plus $11 for 7 searches, and Ultra $29 for 20 searches. No subscription, credits never expire, 30-day money-back guarantee, payments handled by Stripe.

- **Facial-embedding matching:** Compares facial geometry rather than pixels, so the same person can be found across different photos, outfits, backgrounds and years.
- **Scored source results:** Each hit comes back as a source URL with context and a similarity score you can use to sort the strongest leads first.
- **Free guest preview:** Upload without an account to see whether matches likely exist before spending any credit.
- **Local photo quality checker:** A built-in checklist and in-browser checker flag size, resolution and framing problems before you search, saving wasted credits.
- **One-time credits, no subscription:** Buy a pack once; credits never expire and there is no auto-renewal, trial or recurring charge.

**Strengths:** Finds the same person across different photos, where pixel-based reverse image search fails; One-time credit packs instead of a subscription, with credits that never expire; Backend is disclosed openly (FaceCheck.id index), which is unusual transparency for this category; Free guest preview and a local photo check before you spend anything

**Limitations:** Results depend on the target having a public photo footprint, so low-profile people may return little or nothing; Credits are consumed per completed paid search, so poor source photos can waste them; Coverage is limited to the underlying public index the service queries
