Stop hoarding links.
Start building knowledge.

Ronin forces you to capture with intent — so every saved page becomes a structured thinking artifact in your Obsidian vault, not another bookmark you'll never revisit.

01 / The shift

A bookmark is a bet you'll come back. Most of the time, you don't.

Read-it-later apps, pinned tabs, drag-and-drop screenshots — they're all storage with no schema. Your future self pays the tax.

Before · The dump

Links pile up. Context evaporates.

A graveyard of titles you won't recognize next week, scattered across four apps and a notes file called "misc.md".

One page. One intent. One structured note.

Ronin asks why you're saving before you save — then writes the note in the shape your future self can use.

02 / How it works

Three keystrokes between hm, interesting and a note worth keeping.

01

Capture anything

Hit ⌘⇧K on any page, selection, or YouTube video. Ronin reads the source, the timestamp, the highlighted text — whatever you've got.

02

Choose intent

Pick why you're saving this. The intent determines the template, the folder, and the questions Ronin will ask.

AI structures & saves

Local LLM (Ollama) extracts the meaningful bits, fills the template, and writes a markdown file straight into your vault. No round-trip.

03 / Features

Everything you need. Nothing you don't.

Full Page Capture

Reader-mode extraction strips ads, nav, and tracker bait. You keep the article, not the chrome.

Text Selection

Highlight exactly the passage you care about. Surrounding context is preserved as a quote block.

YouTube Capture

Pulls the transcript, the timestamp you paused at, and the chapter title. Citations come for free.

Local-first

Local AI (Ollama)

Runs Llama, Mistral, or whatever you've got installed. Your reading habits never leave the machine.

Direct Vault Save

Writes markdown straight to your filesystem. No sync, no API, no middleman to break next year.

Structured Templates

Each intent ships with a schema. Rewrite them in plain markdown — they're your templates.

04 / Two intents

Every save begins with why.

Two built-in intents cover the modes most knowledge workers actually use. Each one shapes a different note.

05 / Voices

From people who already think in markdown.

My vault used to be a graveyard of orphan notes. Ronin made me commit to a reason before saving — now everything I capture connects to something.

The trade journal template alone is worth it. I went from "I read something good" to a structured rationale I can review weeks later.

Local-only, runs against my own Ollama, writes plain markdown. This is the first capture tool I've trusted to keep around.
