Build with AI Claude

The 6-tool stack I'd use to start a business today

Hey, it's Cindy ๐ŸŒฑ You commented MYSTACK, so here is the full breakdown: the six tools, what each one is genuinely for, what it actually costs.
btw the waitlist for AI System Club is now open! If you're keen on using AI to automate your content, video editing, job search, business or build AI agents, feel free to sign up (only if you want to hehe). Ps. the waitlist gets first dibs:)
๐Ÿ’ก Pick a hub before you pick tools. Most stacks fail because there is no centre: your notes are in one app, your numbers in another, your meetings in a third, and you are the integration. Claude is the hub here, and every other tool in this list either feeds it or gets fed by it. If you only do one thing from this guide, do that.

The whole stack on one page

Six tools, and every one of them except Claude Code has a real free tier you can start on. Read this as layers rather than logos: a brain, a pair of hands, a renderer, a memory, an ear, and the plumbing. If you understand what each layer is for, you can swap any individual tool later without rebuilding your setup.

๐Ÿง  Claude, the hub Writing, analysis, planning, and the connector layer that talks to everything else. One place, one context, one bill.Free to start, around $20 a month for Pro
๐Ÿ‘ฉโ€๐Ÿ’ป Claude Code, the hands Turns the repeating jobs into commands that produce real files: reports, scripts, renamed folders, whole websites.Included with a paid Claude plan
๐ŸŽจ Nano Banana, the renderer The image model for ad creative, thumbnails, slide visuals and product shots. Claude writes the art brief, this draws it.Free tier in Google AI Studio, limited usage
๐ŸŒฑ Notion, the memory Notes, tasks, content calendar and client records in one place, and Claude can read and write it directly.Free for one person, $10 per member a month on Plus
๐Ÿ’Œ Fathom, the ear Records and transcribes your calls so nobody takes notes, and every meeting becomes text Claude can work with.Free for unlimited recording, from $16 a month for AI action items
๐Ÿ“ฎ Google Workspace, the plumbing Email, calendar, docs and file storage. Unglamorous, unbeatable, and Claude connects to all three of the parts that matter.A personal Google account works to start

tool one

Claude, the hub

Everything else in this list is a spoke. Claude is where the thinking happens and where the other five tools plug in, which is why the setup order matters: get this right and the rest is twenty minutes of clicking.

The single highest-leverage move is a context file. One document that says who you are, what you sell, who you sell it to, and how you write. Put it in a Claude Project and every conversation inside that project starts already knowing your business, so you stop re-explaining yourself five times a day.

  1. ๐Ÿ†• Make the project. In the Claude app, click Projects, then New project, and call it your business name. Projects are on the Free plan too, capped at a small number, so you can test this before paying anything.
  2. ๐Ÿ“„ Write the context file. Use the prompt below. Claude interviews you, then produces the document. Save the result into the project's knowledge, not into a chat, because chats disappear and project knowledge does not.
  3. ๐Ÿ”Œ Add the connectors. Open Customize, then Connectors. This is where Notion and Google Workspace get wired in, covered further down.
  4. ๐Ÿ” Work inside the project from now on. Every client email, every ad, every analysis. That is the whole habit change, and it is the difference between a chatbot and a hub.
๐Ÿง  build my business context file
I'm setting you up as the hub of my business, so I want one context document you will use in every future conversation.

Interview me first. Ask me one question at a time, and no more than ten questions total, covering: what I sell and to whom, what makes my offer different, my pricing, my customer's three biggest problems in their own words, my tone of voice, the things I never want said in my writing, and what a good week looks like in numbers.

Then write the document itself, organised under clear headings, in plain language, no longer than two pages. End it with a short section called "how to work with me" that tells you how to respond to me by default: how long, how direct, and when to push back on my ideas instead of agreeing.

tool two

Claude Code, the hands

This is the tool most people skip because the name sounds like it is for engineers. It is not. Claude Code is Claude running on your own computer, with permission to read and write actual files, which means it does the jobs a chat window physically cannot: rename four hundred photos, build the weekly report from a spreadsheet, publish a landing page, run the same process every Monday without being re-briefed.

It is included with a paid Claude plan, so this is a second surface on a subscription you already have rather than a new bill. The upgrade that makes it worth it is turning a repeated task into a saved command you can trigger by name.

  1. ๐Ÿ’ป Install it. Follow Anthropic's setup guide, then make a folder for your business, open your terminal in it, and type claude.
  2. ๐Ÿ“„ Give it the same context. Save your context file from tool one into that folder as CLAUDE.md. Claude Code reads it automatically every session, so both surfaces know the same business (how memory files work).
  3. โŒจ๏ธ Turn a chore into a command. Use the prompt below. It writes a saved slash command into .claude/commands/, and from then on you type one word instead of a paragraph (slash command docs).
  4. ๐Ÿ” Add one command a week. After a month you have a small operations team made of text files: the report, the invoice chase, the content repurpose, the inbox triage.
โŒจ๏ธ turn my weekly chore into a command
I do this task every week and I want it to become a saved slash command I can run in one word: [describe the task, for example "turn my raw sales notes into the Monday client report"].

First ask me the three or four things you need to know to do it exactly my way: where the input lives, what the output format is, who reads it, and anything you must never include.

Then write the command file into .claude/commands/ with a short lowercase-hyphenated name, and make the instructions specific enough that a stranger could follow them and produce the same output I would. Finish by running it once on my real input so we can see where it needs tightening, and tell me plainly what you were unsure about.
๐Ÿ’ก The test for whether something belongs in Claude Code rather than the chat window: does it need to touch files, folders, or the same process repeated? If yes, it belongs here. If it is thinking, writing or deciding, the chat window is fine and faster.

tool three

Nano Banana, the renderer

Ad creative, thumbnails, product shots, slide visuals and social graphics all come out of one place instead of four subscriptions. Nano Banana is the image model people reach for when they want edits that actually hold: changing one element while the rest of the picture stays put. You can try it on the free tier in Google AI Studio, where free usage is capped and heavier or automated use is billed through the API, so check your quota before you plan a batch. If you would rather not use a Google product, Reve is the swap I use for anything where text has to render cleanly inside the image.

The connection here is not technical, it is editorial. Claude writes the art brief, the image model draws it. Most people's AI images look generic because they typed nine words. A real brief is a paragraph, and it names lighting, palette, framing and mood.

๐ŸŽจ write my art brief
Using my business context, write image prompts for [what you need, for example "three ad creatives for my launch" or "a thumbnail for this week's video"].

Each prompt must be a single paragraph of 60 to 100 words that an image model can use with no other context, and it must name the lighting (direction and warmth), the colour palette as actual colours, the framing and depth of field, the surface textures, and the mood in three words. Keep my brand palette consistent across all of them so they read as a set.

Give me three variations that differ on concept, not on wording, and under each one write a single line explaining what that version is testing. End with the aspect ratio [4:5].
๐ŸŒฑ Save the prompts that work into your Notion workspace as a small prompt library. The images are disposable, the prompts are the asset. Six months from now you will regenerate the same visual identity in a minute instead of rebuilding it.

tool four

Notion, the memory

Notes, tasks, content calendar, client records, SOPs. Free for one person and $10 per member a month if you bring in a team (Notion pricing). What makes it the fourth tool rather than just an app you already have is the connector: Claude can read your pages and write to them directly, so "log that call in the client database" becomes a sentence instead of ten minutes of copying.

  1. ๐Ÿ”Œ Connect it to Claude. In the app, open Customize, then Connectors, then Add custom connector, and paste https://mcp.notion.com/mcp. Sign in through the pop-up and choose which pages Claude may see. Custom connectors work on every plan, with Free capped at one (connector docs).
  2. ๐Ÿ’ป Or connect it in Claude Code. Run claude mcp add --transport http notion https://mcp.notion.com/mcp, then type /mcp and complete the sign-in (Notion's MCP docs).
  3. ๐Ÿ—๏ธ Let Claude build the workspace. Do not hand-build databases at 11pm. Use the prompt below and it creates the structure, the properties and the views for you.
  4. ๐Ÿ”’ Scope what it can touch. During sign-in, share only the pages Claude needs. Give it your operations hub, not your entire personal life.
๐ŸŒฑ build my operations workspace
Using the Notion connector and my business context, build me a simple operations hub in Notion and tell me what you created as you go.

I want four linked databases: clients or customers, projects with status and owner, a content calendar with platform and publish date, and a tasks database that rolls up to both projects and content. Add the properties that actually get used and skip the decorative ones, then create one dashboard page that shows this week's tasks, anything overdue, and what is publishing in the next seven days.

Keep the structure as small as possible while still answering the question "what needs doing this week", and explain in two lines how I should add things day to day so it does not rot.

tool five

Fathom, the ear

It joins your Zoom, Meet or Teams calls, records, transcribes, and summarises them, so you can hold eye contact through a sales call instead of typing. The free plan genuinely includes unlimited recordings and transcriptions plus instant summaries. The AI action items and follow-up emails sit on Premium at $20 a month, or $16 a month billed annually, which is the honest gate to know about before you plan a workflow around it.

Here is the thing worth knowing: even on the free plan this is a Claude tool, because the transcript is text. Paste it in and every call becomes a follow-up email, a proposal, a task list and a record in Notion.

  1. ๐Ÿ“… Connect your calendar. Sign up at Fathom and connect the calendar you actually run meetings from. It joins bookings on its own from then on, so there is nothing to remember mid-call.
  2. ๐Ÿ—ฃ๏ธ Say it is recording. Not optional. Recording laws vary by country and state, and in plenty of places every participant has to consent. One sentence at the top of the call covers it and nobody has ever minded.
  3. ๐Ÿ“„ Move the transcript to Claude. After the call, copy the transcript and paste it into your Claude project with the prompt below. This is the step that turns a recording into work that is already done.
  4. ๐ŸŒฑ File the output. Ask Claude to write the summary and the actions straight into your Notion client page through the connector, so the record exists without you touching it.
๐Ÿ’Œ turn the call into finished work
Here is the transcript of a call with [who they are and what the meeting was for]. Work through it and give me four things.

One, a five-line summary of what was actually decided, not everything that was discussed. Two, the action items split into mine and theirs, each with an owner and a due date, and flag anything where the owner was never actually agreed. Three, a follow-up email in my voice that confirms the decisions, restates their deadlines, and asks the one question that unblocks the next step. Four, the objections or hesitations they raised, quoted in their own words, because that is the language I want in my marketing.

Then write the summary and the action items into this client's page in Notion.

tool six

Google Workspace, the plumbing

Email, calendar, docs and drive. It is the least exciting item on the list and the one you would miss first. A personal Google account is fine to start, and a business plan gets you your own domain on email, which quietly changes how people read your first message.

Claude connects to Gmail, Calendar and Drive as pre-built connectors, available across plans, with Team and Enterprise needing an owner to switch them on first (Anthropic's Google Workspace docs). Claude mirrors the access you already have, so it cannot see anything you could not, and by default it asks before it sends anything.

  1. ๐Ÿ”Œ Switch them on. Open Customize, then Connectors, and connect Gmail, Google Calendar and Google Drive from the gallery. Sign in once through the Google pop-up for each.
  2. ๐Ÿ“– Start read-only. Give it a week of asking questions before you let it draft anything outbound. You want to trust its judgement on what matters in your inbox before it writes on your behalf.
  3. โœ๏ธ Move to drafts. Claude asks for approval before sending by default. Keep it that way. Drafts you approve is the right amount of automation for anything a customer reads.
  4. ๐Ÿ“ Point it at Drive. Keep your proposals, brand assets and templates in one Drive folder, and Claude can pull the right template into any job instead of you hunting for it.
๐Ÿ“ฎ run my morning triage
Every weekday morning I want the same briefing, built from my Gmail and Google Calendar.

Give me: anything from a client or prospect that is still waiting on a reply from me and how long it has been sitting, anything with a deadline attached in the next three days, my meetings today with a one-line note on what each one needs me to have ready, and the three things that would most move my business forward today based on my business context.

Then draft replies for the waiting emails, in my tone, short, and leave every one of them as a draft for me to approve rather than sending anything. Tell me at the end what you deliberately ignored and why, so I can check your filter.

the actual point

Wire it into one weekly loop

Six connected tools beat sixty disconnected ones because work moves on its own between them. This is what a week looks like once the connectors are in, and none of these steps need you to open more than one app.

  1. ๐Ÿ“ฎ Monday, the triage. Run the morning triage prompt. Claude reads Gmail and Calendar, drafts the replies, and writes the week's priorities into your Notion tasks database.
  2. ๐Ÿ’Œ During the week, the calls. Fathom records everything. After each call, one paste turns it into a summary, an owner-tagged action list, a follow-up email and a Notion record.
  3. ๐ŸŽจ Midweek, the making. Claude writes the art briefs from your context file, the image model renders them, and the winners go into your Notion prompt library so the look stays consistent.
  4. ๐Ÿ‘ฉโ€๐Ÿ’ป Friday, the command. Claude Code runs your saved report command: it pulls the week's numbers, writes the client update in your voice, and files it.
  5. ๐Ÿง  Every month, the review. Ask Claude what it kept having to be told twice, and add those answers to your context file. The stack gets sharper without you managing it.
๐Ÿ’ก Add one tool a week, not six on Sunday. Every connector is a new place your business data travels, and every one deserves five minutes of "what can this actually see". Connect Claude and Google first, live with it for a week, then Notion, then the rest. A stack you trust beats a stack you built fast and quietly stopped using.

the honest total

What this really costs

You can run this entire stack for nothing while you are figuring out whether the business is real. Claude has a free plan, Claude Code needs a paid one, Nano Banana has a free tier in AI Studio, Notion is free for one person, Fathom records unlimited calls free, and a personal Google account costs nothing. The first thing worth paying for is Claude Pro at around $20 a month, because it unlocks Claude Code, which is where the repeatable work lives. The second is Fathom Premium, and only once you are on enough calls that action items matter. Everything else can wait until it hurts.
