Install on a Mac or Windows PC. After setup, with conversation capture on, Claude Code and Codex CLI sessions are saved as notes in your Obsidian vault, filed and linked automatically. Compatible agents can use those notes once they have access to the vault.
Here's what you get
1
Claude Code and Codex CLI conversations are automatically saved as markdown notes in your Obsidian vault
2
Those notes are filed and linked automatically
3
Vault search so a configured agent can search your notes instead of opening files one by one
4
A copy of Claude’s internal project memory in your vault
5
One license covers 3 computers. Optional Mac-only Claude Cowork Bridge, +$5 (total $24)
Vault Search and optional Jev
Jev ranking
Optional add-on
Customers with their own active Jev API key get Jev ranking for better result order. Setup turns it on when it finds your Jev key, and you can turn it off any time. On our tests the right answer landed in the top 5 more often: 61% with Jev vs 47% local only.
Get a key from TypeSafe or OpenRouter. Jev is a third-party service. It is optional and stays off without a key.
One product · your choice of assistant
One product. One machine-based license. The installer does the same work either way — your assistant guides the final checks and choices, and you choose which one. There is no separate Codex add-on or second purchase.
Choose the assistant that checks your setup
Claude Code
Recommended default
Pick this for the most proven path on Mac or Windows. Claude Code is the command-line tool that runs in your terminal—not the Claude desktop app or claude.ai.
Paste the setup prompt into Claude Code, follow its checks, and approve any requested changes.
Codex CLI
Tested on Mac and Windows 10
Pick this if Codex is already your daily coding agent. The installer hands you a Codex version of the same prompt for the final checks and choices.
Tested on Apple silicon Mac and Windows 10 (64-bit) with Claude Code and Codex CLI.
License expectation
The license follows the computer, not the AI tool. Switching between Claude Code and Codex CLI on the same registered computer reuses that machine slot.
Privacy and permissions
Your notes stay in your Obsidian vault. You choose whether to sync that vault to other computers. Activation sends license and device information, and the product checks for updates. Some sensitive text is hidden in captured conversations, but not all. Claude’s project-memory files are copied as they are. Removing helpers does not delete existing vault notes.

Frequently Asked Questions
Do I need to be technical to use this?
No. This page and the installation are built for normal humans. The goal is to help you follow the right order, not turn you into a sysadmin.
Do I need Obsidian Sync?
Not always. But if you want your vault available on more than one computer, it is usually the cleanest path. The guided steps explain when it is worth it and when you can skip it.
How does the install work?
Download the Mac .pkg or Windows .exe. Follow setup to choose or create your Obsidian vault, enter your license, and choose whether to capture conversations. Then paste the finishing prompt into Claude Code or Codex CLI — not ChatGPT or the Claude desktop app.
Can I buy this on my phone?
Yes. To install, open your purchase email on your supported Mac or Windows computer. The installer cannot run on a phone.
How many computers can I install on?
One license covers 3 computers. If you lose the license email, use license recovery. The license still covers 3 computers.
Do I need Claude Code or Codex CLI already installed?
Have access to Claude Code or Codex CLI before the last setup step. Use the command-line version, not the Claude or Codex desktop app. Provider subscription or usage charges are separate and are not included.
What if I get stuck?
Every step is guided, so you can move through the setup in order instead of guessing what comes next.
Can I get a refund?
Yes. If this isn't right for you, we offer a full refund within 14 days of purchase. No questions asked.

Step 3 — What you're agreeing to
- This is a one-time purchase covering up to 3 computers. Activating a computer registers it against that limit; re-running the installer on the same computer reuses its existing slot, and the recovery page can free one.
- Your captured conversations, session notes, and mirrored memory files are written to the vault on your own computer. Their contents are not uploaded to us.
- Activation sends exactly four fields to our activation server: your license token, a device fingerprint, your computer's hostname, and whether the installer is running on Mac or Windows.
- The product may check our fixed version endpoint for a published update. That check does not send your license token or device fingerprint and does not download an update.
- Conversation text is checked for common secrets, but filtering is not perfect. Session-end notes, file paths, and Claude memory copies are not masked.
- Pausing delays exports. When you turn capture back on, saved conversation text from the pause can also be exported. The hourly Claude memory mirror continues even while session capture is off.
- The installer prepares the vault and background helpers. Claude Code or Codex CLI then checks the setup and asks before actions that require your approval, including installing Obsidian or Smart Connections.
- Vault Search runs on your own computer and needs no key. Jev is an optional add-on made by TypeSafe, a third-party company. If a Jev API key is set up (one you add, a key saved for this product, or a TypeSafe key already on your computer; a general OpenRouter key is used only if you say yes), each search can send your question and, for up to the top 30 results, note titles, dates, headings and short excerpts (at most 400 characters) to TypeSafe, directly or through OpenRouter. Without a Jev key nothing is sent to them. You can turn Jev off at any time.

Before you buy: you'll need Claude Code or Codex CLI installed. They're terminal apps — not the Claude desktop app, not ChatGPT. Your assistant guides the final checks and choices after the installer runs. It must be signed in and working. Any assistant subscription or usage costs are separate. Obsidian Sync is optional and is not included.
You'll enter your name, email, and payment details in Stripe. Your account gives you access to free site content, and this purchase unlocks this specific installation.
