What CLARA is
CLARA is a free web-based AI research assistant for exploring, searching, and analyzing archival documents on corporate litigation and climate accountability. It searches more than 1.4 million pages across curated fossil-fuel, chemical and benzene, pharmaceutical, and food-industry collections. Responses include links to specific pages in original documents, allowing you to check cited material. You can upload PDFs, Word files, text files, and images, with a 50 MB limit per file and 200 MB of total storage. A personal Workspace holds research notes and documents; chat prompts can create structured documents there, and version history lets you restore earlier files. Daily research credits reset every 24 hours, do not carry over, and may change. CLARA works in a browser on phones and tablets. It warns that AI responses can be incomplete or inaccurate. Conversations and files remain while the account exists unless deleted.
