Built for Complicated Workflows
For students and researchers, LeapReader addresses a critical challenge: managing information across dozens of sources over extended timeframes.
Traditional approaches often involve:
- Opening multiple tabs
- Manually copying quotes
- Losing track of reviewed sources
With LeapReader:
- Instantly summarize papers as you browse
- Save important quotes or insights into memory
- Maintain context across multiple documents
When writing, you can recall saved quotes and summaries without searching through tabs or files. This creates a seamless research-to-writing pipeline that maintains continuity throughout your project.
Take for example, you are doing research to write a paper. You have multiple tabs open and want to use quotes for your various sources to add to your paper. LeapReader’s extension can help you look for relevant quotes within the article. When writing the paper, you can ask LeapReader to remind you the quotes and add it into your paper. This can streamline the entire research and writing process. This is only possible with the memory from MemMachine. MemMachine helps to store the chat logs to be referenced for later.
Powered by MemMachine
LeapReader’s persistent capabilities are powered by MemMachine, an open-source memory layer that provides true continuity across browsing sessions.
Unlike traditional AI tools that treat each interaction in isolation, MemMachine retains your research context over time through dual memory systems:
- Episodic Memory — saves browsing history and extracted content
- Profile Memory — learns your reading patterns and preferences
This architecture transforms LeapReader from a simple summarization tool into an intelligent research assistant that evolves with your needs.
The system is model-agnostic, supporting major LLMs while keeping your data under your control through on-premises or private cloud deployment options.
Privacy and Accessibility
LeapReader operates primarily within your browser, transmitting content to AI providers only when you explicitly request assistance. Your reading history and research data remain private and secure. The intuitive side panel and context menu interface provide powerful capabilities without cluttering your workspace.
