Noah Brier, Alephic's AI use case

Cofounder at Alephic

Uses Claude Code inside Obsidian as a second brain, giving AI access to roughly 1,500 notes so it can retrieve old research, organize ideas, support deep work, and help him resume thinking after interruptions.

The problem

What was broken before AI

Personal knowledge systems can become graveyards. You save articles, notes, links, and old ideas, but when it is time to write or think deeply, finding the right material can be slow enough that you start from scratch. Interruptions make the problem worse: once you lose the thread, it takes real effort to remember what you were thinking, which sources mattered, and where the idea was going.

What changed

What the use case made possible

Noah points Claude Code at the root folder of his Obsidian vault so it can search across the full note archive instead of one narrow project. For a talk or essay, he creates a dedicated folder, gives Claude the working idea, and asks it to pull useful notes, chats, articles, and research into that space. He also uses Claude Code on mobile through Termius and Tailscale, so the same research and editing setup is available away from his desk.

Why this matters

Why this use case is worth studying

Noah’s workflow works because it treats reading and retrieval as first-class AI jobs. The impressive part is not just that Claude can write; it can help reopen old trails of thought. A personal archive becomes more useful when the assistant can search it, assemble the relevant pieces, ask questions, and remind you where you left off. That makes deep work easier to resume instead of easier to avoid.

Use this when

When this pattern applies

Use this pattern when you have a large archive of notes, research, saved chats, or half-formed ideas, but struggle to find and reuse them when a new project starts. It works especially well for writing, talks, strategy work, research, and any deep work that gets interrupted and needs to be resumed later.

Exponential Builder analysis

01

Retrieval is part of the creative process.

The value comes from letting AI search the archive before the blank page moment, so old notes can re-enter active thinking instead of sitting as storage.

02

Project folders give the assistant a useful boundary.

Pointing Claude at the full vault helps it find connections, but asking it to gather material into one project space turns broad access into focused work.

03

Continuity may be the underrated AI use case.

A thinking agent that tracks open questions, progress, and changes helps reduce the cost of interruption, which matters as much as faster drafting for deep work.

What to avoid

Mistakes and warnings

Where this pattern can go wrong if you copy it too literally.

Do not expect AI to make big conceptual leaps from messy notes without guidance.

Avoid dumping every note into a project folder without asking what is actually relevant.

Keep sensitive personal or client notes out of any workflow you do not fully trust.

Do not jump straight to writing if the idea still needs thinking.

Watch for the assistant over-summarizing old notes and flattening the nuance that made them useful.

Public workflow preview

The shape of the workflow

A high-level look at how the use case works, with the reusable pattern made clear.

01

Put the notes where AI can read them

Noah keeps his Obsidian notes in a local folder structure that Claude Code can access.

02

Start in thinking mode

He tells Claude Code to help him think before asking it to write, which slows the model down and encourages better questions.

03

Create a project space

For a talk, essay, or research project, he makes a dedicated folder where Claude can gather the useful material.

04

Search the old archive

Claude looks through roughly 1,500 notes to find relevant ideas, sources, clips, and connections.

05

Use an agent to keep the thread alive

A thinking agent tracks questions, progress, and what has changed so Noah can resume work after interruptions.

06

Bring the setup to mobile

With Termius and Tailscale, he can reach the same Claude Code environment from his phone when he is away from his desk.

Copy the pattern

The reusable idea

Pattern in one sentence

Turn your note archive into an active thinking partner by giving AI access to the material, a clear project folder, and the job of helping you recover the thread.

Reusable idea

Noah’s workflow is a good reminder that your notes become more valuable when AI can work inside the system where they already live. Instead of building a perfect second brain, start by making your existing archive searchable and project-specific. Give AI a folder, a job, and permission to gather the useful fragments. The value shows up when you can return to an idea days later and recover the thread in minutes.

Steal this workflow

Use this for one essay, talk, memo, or research question:

1

Create a project folder with three subfolders: Research, Chats, and Progress.

2

Add a short project brief: working title, current thesis, audience, and what you are trying to figure out.

3

Ask the assistant to search your broader notes for relevant ideas, sources, clips, prior chats, and unresolved questions.

4

Have it copy or link only the useful material into the project folder, with a one-line reason each item belongs there.

5

Ask for a “thinking brief” before drafting: strongest existing material, contradictions, missing evidence, and questions to answer next.

6

At the end of each session, save a progress note: what changed, what is still open, and the next best action.

7

When you return, ask for a catch-up summary from the project folder before writing anything new.

Suggested prompt

“We are in thinking mode before drafting. I’m working on [talk/essay/research question] about [working idea]. Search the rest of my Obsidian notes for anything that may be useful: prior notes, saved chats, articles, PDFs, references, and related ideas. Create or update a project folder for this work. Pull in only the most relevant material, explain why each item matters, list open questions, and end with a short catch-up brief I can use to resume the thread later.”
