# PublicAI > Building the human layer of AI PublicAI is a decentralized data infrastructure company for AI training. It lets contributors earn crypto rewards for labeling, annotating, and validating multimodal datasets. PublicAI is a company that builds decentralized data infrastructure for artificial intelligence training, connecting AI builders with a global network of human contributors. Its platform lets people earn rewards for labeling, annotating, recording, and validating datasets used to train and evaluate AI models. It targets AI companies seeking human-verified training data and individuals worldwide looking to monetize data-related skills. The platform addresses the problem of AI models trained on synthetic data losing accuracy and diversity by keeping humans in the loop across both training and inference stages. Contributors complete tasks such as audio recording, text and video annotation, and data validation, while a staking mechanism with slashing is used to incentivize quality and deter low-effort submissions. A consensus layer helps verify accuracy of contributions across text, audio, video, and mapping data formats. Its main offering, the Data Hub, is complemented by a browser extension called Data Hunter for sourcing content and a business-facing service for enterprise clients seeking curated speech and text datasets. Contributors can stake the platform's native token as quality collateral and participate in reward campaigns tied to specific data types. The platform is used by AI developers sourcing training data and by a distributed base of workers, validators, and dataset builders. - Type: Company - Sector: Data & Analytics - Status: Active - Founded: 2023-01-01 - Profile: https://thegrid.id/profiles/publicai ## Products - [PublicAI Data Hub](https://thegrid.id/profiles/publicai): PublicAI Data Hub is a decentralized data collection and validation platform that coordinates human contributors to produce AI training datasets. Contributors complete campaign-based data collection, annotation, and multiple-choice consensus voting tasks, staking PUBLIC tokens as quality collateral and earning rewards when responses match the consensus outcome. A companion Chrome extension lets users earn passively by posting AI-generated replies to social media posts in a chosen tone, capped at a daily limit and paid out monthly in PUBLIC tokens or a dollar-pegged stablecoin. Enterprise clients access curated multimodal datasets, including speech recognition and voice synthesis collections, through an integrated data API suite and vector database. (DePin, Live, Main Product) ## Assets - [PublicAI (PUBLIC)](https://thegrid.id/profiles/publicai): PUBLIC is the utility token of the PublicAI ecosystem. It is used for staking as collateral in data collection campaigns, governance voting, and earning platform rewards. Token issuance is tied to actual platform revenue through a revenue-driven mechanism, aligning token supply growth with data services demand.
