The Complete AI Stack for a One-Person Business (2026)

Running a one-person business means doing the work of three people. The right AI stack doesn’t replace the work — but it compresses the time required dramatically.

This is the exact stack we’d build for a solo consultant, freelancer, or solopreneur starting from scratch today.

The Stack at a Glance

Total monthly cost: £26–66/month depending on tiers.

Why This Stack

Every tool in this stack was chosen because it solves a real problem that solo operators face:

• Claude: The core intelligence layer. Writing, analysis, research, drafting, summarising.
• Notion AI: Your second brain. Meeting notes, project docs, knowledge base — all searchable by AI.
• Zapier: The automation backbone. Connects your tools so repetitive tasks happen without you.
• Grammarly: The safety net. Catches errors and tone issues before they go to clients.
• Canva: Visual content without a designer. Social graphics, presentations, basic branding.

Tool 1: Claude Pro (£18/month)

Claude is the workhorse. In a typical week, we use it for:

• First drafts of client proposals, emails, and reports
• Summarising long PDFs and research documents
• Generating outlines and content plans
• Answering questions about our notes and docs (via Projects)
• Proofreading and tone-checking documents

Setup: Sign up at claude.ai, create a Project for your business, and upload your brand guidelines, tone of voice document, and a few example pieces of your writing. Claude will use these as context for every conversation in the project.

Tool 2: Notion + Notion AI (£8/month add-on)

Notion is the knowledge layer. We use it for:

• Client project docs and notes
• Meeting notes with AI summaries
• Content calendar and publishing tracker
• SOPs (Standard Operating Procedures)
• CRM-lite for client contact management

Setup: Start with Notion’s free tier. Build out your core databases (projects, clients, content). Then add the Notion AI add-on at £8/month. Connect Notion to Zapier to automatically create project pages when you onboard new clients.

Tool 3: Zapier (Free → £29/month)

Zapier is the invisible thread that connects everything. Start with the free tier (100 tasks/month) and build these automations first:

1. New client inquiry → Notion project page (via Tally or Typeform)
2. Published article → Social media post (your CMS → Buffer or Hootsuite)
3. New invoice paid → Thank you email (Stripe → Gmail)
4. Weekly content calendar → Slack digest (Notion → Slack)

Start with just one automation. Get comfortable. Then add more.

Tool 4: Grammarly (Free)

The free tier of Grammarly is all most solo operators need. Install the browser extension and it works everywhere — Gmail, Notion, Google Docs, LinkedIn. It catches typos, tone issues, and clarity problems before they reach clients.

If you write a lot and want the advanced style suggestions, the paid tier is reasonable — but start free.

Tool 5: Canva (Free → £11/month)

Canva’s AI features — Background Remover, Magic Write, and Magic Design — are genuinely useful for solo operators who need professional-looking visuals without a designer. The free tier covers most needs. The paid tier at £11/month is worth it if you produce a lot of visual content.
