A minimal, extensible terminal coding agent you can reshape
Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
High-quality human data for AI training, evaluation, and research
Filter participants by detailed demographic, professional, and behavioural criteria and reach narrow or representative samples rather than a generic crowd.
Collect human preference data for model fine-tuning, run safety evaluations and red-teaming, and use a feedback API to plug humans into automated pipelines.
Attention checks, honesty screening, and approval workflows help filter out careless or fraudulent responses before you analyse results.
Publish a study and begin collecting responses quickly, with tooling that supports screening, quotas, and longitudinal designs.

Free / Open-sourceThe industry-standard source code editor with flexible plugin support, requiring extensions for advanced agentic coding.

An IDE plugin that reads entire codebases for multi-file tasks, trading terminal minimalism for integrated UI.

Large consumer panel for market research surveys, but lacks Prolific's specialized focus on academic studies and AI tuning.
SpecialistAn autonomous software engineer that handles end-to-end repository tasks, but operates as a cloud service rather than locally.

A terminal-first AI coding agent optimized for open-weight models, offering a similar command-line developer experience.

SpecialistThe environments frontier AI trains on, and the agents that do the recurring work
An AI-powered integrated development environment providing comprehensive project understanding, but operating as a desktop app.

Enterprise-grade data annotation and AI alignment workforce, but less self-serve for academic study recruitment and casual surveys.

SpecialistAI data infrastructure for building production-grade models

SpecialistSpecializes in video-based consumer interviews and AI qualitative analysis, but less focused on quantitative academic survey panels.
