After skill screening, contributors are matched to projects that fit their domain, from coding and math to linguistics and medicine.
No minimum hours and fully remote work, so experts can fit tasks around study, research or a primary job.
Typical work includes writing hard prompts, producing grading rubrics, ranking competing answers and reviewing model reasoning.
Contributors are paid for approved work each week, with rewards that scale with the quality of their output.
Graph, vector and text retrieval for AI agents on your Postgres
Query graph, vector, full-text and hybrid retrieval through one consistent interface instead of stitching multiple systems together.
The open-source pgGraph engine follows relationships across your records, enabling multi-hop and shortest-path retrieval without moving data.
Semantic search over embeddings combines with sparse and full-text matching so queries that mix meaning and exact terms still work.
A dashboard playground, CLI for imports and configuration, and a typed Python SDK make it straightforward to prototype and then ship.
