Open-source tools built by the community to advance open science research.

Open Science Assistant (OSA)

The First Modular AI Assistant for Open Science

OSA is an extensible AI assistant platform designed specifically for open science practitioners. Built with modern AI infrastructure, it provides domain-specific assistance for research tools and workflows.

Key Features

Modular Architecture

Extensible design supporting document retrieval, validation, and code execution. Add new assistants and tools as your research needs evolve.

Multi-Source Knowledge

Integrates knowledge from GitHub repositories, OpenALEX, Discourse forums, and mailing lists to provide comprehensive research support.

Production Ready

Built with LangGraph/LangChain and FastAPI, featuring production observability through LangFuse integration.

Supported Research Domains

OSA provides specialized assistance for major open science tools. By end of January 2026, full support will be available for:

HED

Hierarchical Event Descriptors (HED) is a framework for annotating experimental data with standardized, machine-readable vocabulary.

BIDS

Brain Imaging Data Structure (BIDS) is a standard for organizing and sharing neuroimaging and electrophysiology data.

EEGLAB

The most comprehensive and widely-cited open-source software environment for human neuroscience, processing EEG, MEG, and other electrophysiological data.

More Coming

The modular design enables adding support for additional research tools and domains.
