Introduction to Linkly AI

Today’s AI assistants are becoming increasingly powerful. In our work and studies, we need to provide more and more personal data, notes, knowledge, and documents to AI assistants. We need a simple, efficient, secure, and unified way to accomplish this. Linkly AI was built to solve exactly this problem.

For human users, Linkly AI is a full-text search tool with an exceptional experience

  • Quickly index documents on your computer, creating full-text and outline indexes
  • Find target documents through keywords and natural language
  • Say goodbye to the outdated, inefficient folder-and-tag-based document management — just drop your documents on your computer, and Linkly AI will manage, find, and utilize them for you
  • Currently supports PDF, DOCX, TXT, Markdown, HTML and more formats, with additional formats coming soon

For AI assistants, Linkly AI is a powerful context retrieval and reading tool

  • Delivers documents from your computer to AI assistants in an AI-friendly format, progressively
  • Supports both MCP and CLI for use by AI Agents
  • Provides official Skills to guide AI Agents in installation and usage
It is NOT:
  • Another AI chat application
  • Another note-taking or knowledge base software
You can continue chatting in your favorite chatbot, taking notes in your preferred note-taking app, and then connect everything to any AI assistant through Linkly AI. No frequent imports or switching needed. It can run entirely locally, ensuring data security and privacy from the ground up.
Your computer is your best AI knowledge base.

​
Who Is It For?

Linkly AI is built for all knowledge workers, creators, students, researchers, and small teams who struggle with managing large volumes of documents and fragmented knowledge. If you have ever faced the following challenges, consider using Linkly AI:

Information Fragmentation

PDFs, DOCX files, web pages, notes, and other documents scattered everywhere — you want to find specific content but don’t know where to start

Time-Consuming Organization

Categorizing, tagging, creating folders — enormous effort with high maintenance costs

Inefficient Search

Only able to search documents by file name from memory, while the content you need is buried in the body of some file, and you only remember the gist

Knowledge Hoarding

Content painstakingly collected and organized, yet impossible to integrate or apply — resulting in massive “knowledge inventory” gathering dust.
These problems were never efficiently solved — until the advancement of AI technology. Technologies like LLM, RAG, and Agent have effectively addressed the challenges of knowledge retrieval and utilization. However, when you try most AI knowledge base products on the market, you will find they still have the following issues:
Most AI knowledge bases, constrained by cost and use cases, rely on simple RAG to search document fragments, yielding subpar results.
Most AI knowledge bases run in the cloud, requiring data to be uploaded first. This easily leads to data privacy, security, and sovereignty issues.
Cloud-based AI knowledge bases, constrained by their own costs, can only offer limited free capacity and restricted usage quotas. Users must pay for subscriptions to unlock more capacity and features.
They compete with your existing AI assistants for attention. What was supposed to solve knowledge fragmentation ends up requiring you to spend effort on migration and synchronization first.
