• PDF.ai — PDF.ai lets students upload any PDF and immediately start asking questions about the content in a chat interface. It works with textbooks, research papers, syllabi, and any other PDF academic materials. The tool highlights the exact source passage in the document that corresponds to each answer for easy verification.
• Scite.ai — Scite displays how academic papers are cited by others, classifying each citation as supporting, contrasting, or merely mentioning the original claim. This helps students quickly assess whether a paper's findings are well-supported or contested in the field. Many university libraries provide institutional access at no cost to enrolled students.
• Glasp — Glasp is a social web highlighter that saves highlights from webpages and YouTube videos and surfaces what other readers highlight in the same content. Students can discover important passages they may have skipped by seeing community-sourced highlights from researchers in their field. The AI generates daily summaries of all saved highlights.
• Consensus Summarizer — Paper Digest delivers daily email summaries of the most impactful new academic papers across selected research fields. Students subscribe to their discipline's digest to stay current with cutting-edge research effortlessly. Each summary is concise enough to read in under two minutes and includes a link to the full paper for deeper reading.
• Liner PDF — Liner PDF extends the Liner highlighting experience to uploaded PDF documents, allowing students to annotate, highlight, and get AI explanations of confusing passages directly within the reading interface. Annotations sync across all devices so highlights made on mobile appear on desktop and vice versa. The note export feature compiles all highlights and annotations into a structured study document.
• Liner AI — Liner is a browser extension that lets students highlight text on any webpage or timestamp YouTube videos, building a personal annotated archive of research materials.

Law students use it to quickly identify key clauses in case law, while all students benefit from understanding the academic policies and agreements they must sign. The PDF upload feature handles most legal document formats.
• Lateral AI — Lateral allows students to upload a collection of research papers and automatically extracts recurring themes, creating a visual matrix showing which papers discuss which concepts.

The export to Notion lets students move directly from research mapping to writing.
• Elicit — Elicit is designed for academic research, helping students find relevant papers, extract key data from studies, and map the literature around any topic.
