Lateral
Research discovery app that helped search organize and annotate papers which was sunset on June 26 2025 with resources archived for users.
Overview
Lateral provided a unified workspace for academic and market researchers to collect PDFs, extract highlights and search across a personal library. Super Search indexed documents so you could find sections by concept rather than exact keywords and projects organized notes for literature reviews. The team announced a sunset on June 26 2025 to focus on a new direction, leaving guidance for exporting data and contacting support.
Existing users could preserve work by downloading libraries and highlights and many migrated to alternatives in the same space. Lateral’s design influenced how modern tools combine semantic search with citation management and remains a useful reference for product teams building research hubs. If you need an active product today, evaluate successors that offer local indexes, web clipping and AI assisted summaries while supporting standard citation exports to keep your corpus portable.
