Obsidian + Claude + n8n = $8,000+ per month in retainers.

Every company has a wiki. A Google Drive folder nobody opens. A Notion workspace organized once in 2022. A Confluence page where processes die.

The problem is not the tool. The tool does not talk back.

Obsidian connected to Claude talks back. It reads every note, process, client file, meeting summary. Answers like a colleague who read everything and forgot nothing.

Six clients. $2,200 setup each. $1,500 monthly retainer each. $9,000/month recurring plus new setups.

Here is the complete system.

What Obsidian actually is Plain markdown files on the local machine. No cloud. No subscription for core. Claude reads the entire vault for full context.

Storage is easy.

Retrieval is the product.

Personal vault vs enterprise vault

Enterprise version sells itself. Executives see the demo and want it immediately.

How it works technically

Obsidian = knowledge. Claude = intelligence. n8n/Telegram = interface.

Employee asks in chat. Bot pulls files, applies role prompt, answers with source and date.

Building the vault structure

Use this prompt to generate the full tree:

1You are an expert knowledge architect for enterprise Obsidian vaults.
2
3Client: [industry, team size, main pains]
4
5Output this exact hierarchy with purpose for every folder and key file:
6
700_INBOX/
801_COMPANY/ (Mission, Org Chart, Values)
902_PROCESSES/ ([Dept] subfolders with process files)
1003_CLIENTS/ ([Client] folders)
1104_PEOPLE/ (employee profiles)
1205_MEETINGS/ (dated notes)
1306_DECISIONS/
1407_TEMPLATES/
1508_SYSTEM/ (CLAUDE.md + Role_Prompts/)
16
17One sentence purpose per item. Clean markdown tree only.

Then populate each file with this prompt:

1Write the complete first draft of this vault file.
2
3Path: [full path]
4Purpose: [from tree]
5Company context: [details]
6
7Rules:
8- YAML frontmatter: title, last_updated, owner, tags
9- Clear headings
10- Concrete examples and numbers
11- "Related notes" section at end
12- Precise, actionable tone

The system prompt that makes it work Different prompt per role.

Associate example:

1You are the firm’s living memory for [Firm Name].
2
3Full vault access. Always cite source note + last_updated date.
4
5You speak to a junior associate.
6Answer only documented info.
7If missing or >90 days old, flag it and name owner.
8
9Never invent procedures or give legal advice.
10
11Format:
121. Direct answer (max 3 sentences)
132. Source + date
143. Related notes

Ops role prompt follows the same pattern with different restrictions.

The n8n workflow Telegram trigger → identify user role → load system prompt → retrieve vault context → Claude API → save history → reply.
