I built a second brain in 10 minutes. Here is the exact stack

Granola + Claude. $38/month. Replaces $78K/year of work most operators are still doing by hand.

3 people. Same problem.

1. a founder running a 5-person team sits in 22 meetings a week

2. a consultant logs 40+ calls a month and forgets the one from yesterday

3. a buy-side analyst spends 30 hours a week on data gathering before she does any thinking

The bottleneck is the same in every case:

Your most valuable conversations evaporate the moment they end.

You take notes. You forget to type them up. You search Slack for what was decided. You ask the other person what they said.

You waste 11 hours a week on context recovery that an AI did 6 months ago.

The $38/month stack that fixes it:

▫️ Granola for capture: $18/month

▫️ Claude Pro for thinking: $20/month

Two tools. One MCP connection. A second brain that listens, organizes, and thinks alongside you.

Why now: Granola just raised $125M at a $1.5B valuation in March 2026, with 250% revenue growth in one quarter and enterprise clients including Vanta, Gusto, Asana, Cursor, Lovable, and Mistral.

The category stopped being “AI note-taker.” It became the context layer underneath every AI workflow.

This is the 10-minute build, the 8 prompts that ship the moment it is live, and the ROI math that makes the decision obvious.

The ROI math (do this part first)

Your investment: $38/month. $456/year.

$456 in. Roughly $90K out.

For a 5-person team, the math compounds to $450K/year recovered. For a 50-person SMB, $4.5M.

The math is the article.

Why now: the signal in the numbers

Granola’s Series C is not the story. The growth curve is.

▫️ $1.5B valuation in March 2026, up 6x from $250M one year prior

▫️ $125M Series C led by Index Ventures and Kleiner Perkins

▫️ 250% revenue growth in the single quarter before the raise

▫️ 11 hours per week saved per user (company-reported, consistent with internal benchmarks)

▫️ Enterprise client list reads like the AI Corner archive: Vanta, Cursor, Lovable, Mistral, Asana, Gusto, Thumbtack, Decagon

The thesis underneath:

No meeting bot. Local capture. Clean enhanced notes. MCP-native context any AI tool can query.

Meeting bots failed because nobody wants a third-party recorder visibly joining their Zoom call. Granola runs locally on your device. The other side sees nothing.

That single design decision is why Granola won the category.

The 9-step build (10 minutes, no code)

Step 1: Press record

▫️ Download Granola. Open it. Tap record. Talk.

▫️ Auto-transcribes on Zoom, Meet, Teams, WebEx, Slack Huddles. Works in person.

▫️ No bot joins the call. The other side sees nothing.

Step 2: Clean notes ship automatically

▫️ Do nothing after the call.

▫️ Granola generates summary, key points, decisions, action items.

▫️ Raw transcript preserved alongside.

Step 3: Search across every meeting

▫️ Every conversation in one place.

▫️ Google for your brain. Worth $18/month on its own.

Step 4: Ask your notes questions

▫️ “What did they want?” “What did we agree on pricing?” “Which customer mentioned the integration request?”

▫️ Granola’s chat went agentic in April 2026. Inline citations. Fast search.

Step 5: Sync your calendar

▫️ Connect Google Calendar once.

▫️ Every meeting auto-captures. Notes start the moment the meeting starts.

▫️ Granola stops being a tool. It becomes a layer running underneath your day.

Step 6: Share in one click

▫️ Native integrations push directly to Slack, Notion, HubSpot, Affinity, Attio.

▫️ Sales calls flow into your CRM. Customer interviews flow into Notion. Investor calls flow into Slack.

Step 7: Plug it into Claude via MCP (the unlock)

This is where the second brain becomes a thinking partner.

▫️ Granola → Settings → Connectors → Claude. OAuth in 30 seconds.

▫️ Claude can now read every meeting you have ever had. Find patterns across hundreds of conversations. Generate content from your actual context, not the public web.

▫️ MCP launched February 2026. By March, Granola was live in Claude, ChatGPT, Cursor, Lovable, Figma Make, Replit, Manus, v0, Bolt.new, Duckbill, and Dreamer.

One authentication. Universal access. The USB-C of AI apps.

Step 8: Let Claude organize your entire brain

Read my last 30 days of meetings via Granola MCP.

Organize them into 4 categories:
1. Content opportunities (recurring themes I should write about)
2. Client patterns (what they keep asking, what they push back on)
3. Product ideas (problems mentioned 3+ times)
4. Promises I made and have not actioned

For each, cite specific meetings (date + title) so I can trace 
back to source.

Then suggest the top 3 things I should do this week based on 
patterns you see.

90 seconds replaces 4 hours of manual review.

Step 9: Make it your daily SOP

▫️ Morning → ideas dumped in Granola

▫️ Day → calls auto-captured

▫️ Evening → Claude organizes, suggests next steps

You stop forgetting. You stop rewatching calls. You stop guessing what is next.
