Ponder

Ponder is a web-based AI research workspace for students, analysts, researchers, and creators who need to turn scattered sources into structured, connected knowledge.

Key capabilities include:

• Source ingestion and indexing for PDFs, videos, and web pages, with library management and a 150MB per-file upload limit on most plans
• AI chat over documents to ask questions, extract insights, generate summaries, and draft AI-assisted literature reviews across peer-reviewed papers and uploaded materials
• Knowledge graph and infinite canvas for visual mapping, connecting ideas across sources, and exploring patterns as projects evolve
• Team collaboration and search with shared projects/folders, real-time updates, and semantic search across personal libraries, team libraries, and external databases, ranked by relevance

Pricing: Freemium with Free ($0/month, 50 AI credits/day), Casual ($8/month billed yearly, 800 AI credits/month), Plus ($24/month billed yearly, 2500 AI credits/month), and Pro ($48/month billed yearly, 6000 AI credits/month). All plans include unlimited projects (Ponders).

Notable for combining conversational AI with a visual knowledge graph and infinite canvas in one workspace, plus exports like mind maps (PNG/HTML) and Markdown. It was formerly known as ResearchFlow.
