Similarity

Find notes by meaning—not just keywords.

Similarity helps you uncover hidden connections across your Obsidian vault by understanding what your notes actually say, not just what words they contain.

Runs fully local. No APIs. Your data never leaves your machine.

What it does

Search by meaning

Look up notes based on intent, not exact phrasing.

Browse related notes instantly

Jump through semantically similar notes and explore ideas that are actually connected.

Why this matters

Folders and tags force structure upfront.
Similarity lets structure emerge naturally.

• Discover notes you forgot existed
• Connect ideas across different topics
• Reduce reliance on rigid organization

Features

• Semantic search – find notes by meaning, not keywords
• Related notes view – explore connections instantly
• Fully local – runs entirely on-device
• No external APIs – zero data leaves your vault

Privacy

This plugin is built around one principle: your notes stay yours.

• All processing happens locally
• No internet connection required after install
• No tracking, no telemetry, no external services

Why Similarity

There are many great plugins in this space, each with their own strengths and approaches.

This plugin is built around a different set of priorities:

• Fully local, by design – your data never leaves your device. No APIs, no background calls, no risk.
• Lightweight and fast – minimal overhead, built to stay responsive even as your vault grows.
• Keeping it simple – hiding all the complicated parts so you can focus on writing.
• Focused experience – no fancy AI LLM agents, just practical semantic discovery that fits naturally into your workflow.
• Cross-platform consistency – works on desktop and mobile, with a shared index so you don’t need to reindex per device.
