The AI stack for a one-person business in 2026

A one-person business does not need twenty AI subscriptions. It needs a small set of tools that cover the jobs you do every week: thinking and writing, research, organising, automating repetitive steps, making visuals, editing audio and video, and checking your writing.

This guide describes a practical stack for 2026, organised by job rather than by brand. For each tool you will find what it is good for in a freelance business and the plan facts we checked on the official pricing pages on 30 September 2026. Prices and plan limits change often, so always check the pricing page before you subscribe.

Start with jobs, not tools

Before adding anything, list the tasks you repeat every week and how long they take. A typical list for a freelancer looks like this:

• Writing: proposals, emails, client deliverables, posts
• Research: market questions, competitor checks, fact-checking
• Organising: client projects, notes, templates, SOPs
• Admin: onboarding, invoices, follow-ups
• Marketing: social posts, newsletter, case studies, simple graphics
• Media: recording and editing video or podcast content

Then pick at most one tool per job. Only add a second tool when the first clearly cannot do something you need every week.

Thinking and writing: ChatGPT or Claude

A general assistant is the centre of most solo stacks. You use it to draft proposals, rewrite emails, summarise call notes, outline content and review code.

ChatGPT from OpenAI offers a free tier and several paid plans. Check the current plan list on the official pricing page, as tiers and limits have changed several times.

Claude from Anthropic also has a free plan. On the official pricing page, Claude Pro is listed at $20 per month with monthly billing, or $17 per month when billed annually ($200 upfront). Max plans with higher usage start at $100 per month.

Which one to pick? Try both on your real tasks for a week, using the same prompts. Good tests:

• Paste a messy call transcript into the call notes to recap prompt and compare the results.
• Run the line edit prompt on a piece of your own writing and see which keeps your voice better.

Most solo operators end up paying for one and using the free tier of the other as a second opinion.

Research: Perplexity

For research where you need sources, a search-based assistant saves time. Perplexity answers questions with inline, clickable citations, according to its help center, which makes it easier to open and verify each source. It has a free plan with usage limits and a paid Pro plan with higher limits.

Pair it with the research brief prompt, which asks for sources, dates and confidence levels for every claim. Whatever tool you use, open every link before a number goes into a client deliverable. Citations make checking faster; they do not replace it.

Organising: Notion

You need one place for client projects, notes, templates and procedures. Notion has a free plan. According to its pricing page, full Notion AI features are included in the Business plan, while the Free and Plus plans include a limited AI trial.

For a solo business, a simple setup works well:

• A clients database with status, contact, rate and links
• A projects database linked to clients
• A templates page for proposals, scopes and welcome packs
• An SOP page for repeated processes

Use the SOP prompt to turn your rough checklists into procedures you can store there, and the weekly review prompt to keep a running log.

Automation: Zapier

Automation connects your tools so that routine steps happen without you. Zapier has a free plan. Its pricing page lists 100 tasks per month on the free plan and limits it to two-step Zaps, meaning one trigger and one action. Multi-step Zaps require a paid plan. The Professional plan starts at $19.99 per month billed annually, or $29.99 billed monthly, for 750 tasks.

For many freelancers, the free plan is enough to start. Examples of useful two-step automations:

• New booking in your scheduling tool creates a row in your clients database
• New signed contract sends a welcome email
• New form submission creates a project page

Map your process first with the onboarding automation map prompt. It sorts steps into automate, template and keep personal, and tells you which workflows need more than one action step.

Visuals: Canva

Social graphics, proposal covers, carousels and simple presentations are the usual design needs. Canva has a free plan. According to Canva, Brand Kit, where you store logos, colours and fonts, is a Canva Pro feature. If you make branded graphics every week, Brand Kit is often the reason to upgrade.

Audio and video: Descript

If you record videos, podcasts or client training, Descript lets you edit video by editing a text document of the transcript, as its site describes it. Deleting a sentence in the text removes it from the recording. There is a free plan, and paid plans are priced by media hours per month on its pricing page.

It pairs well with the content repurposing prompt: record once, get a transcript, and turn it into posts and a newsletter section.

Final check on writing: Grammarly

Grammarly works inside your browser and apps. Its free plan covers spelling and grammar corrections and shows the tone of your writing, and includes a monthly allowance of AI prompts. A Pro plan adds more features.

Use it as a final pass on client-facing text. It is not a substitute for rereading your work out loud.

Three example stacks

The lean stack (mostly free plans)

• One assistant on its free plan
• Notion free for projects and templates
• Zapier free for two or three two-step automations
• Canva free
• Grammarly free

Good for: new freelancers testing what they actually use.

The writer or consultant stack

• A paid plan on ChatGPT or Claude
• Perplexity for research
• Notion for projects and SOPs
• Grammarly for final checks

Good for: people whose deliverables are mostly written.

The content-heavy stack

• A paid assistant plan
• Descript for video and podcast editing
• Canva Pro for branded visuals
• Zapier for publishing and onboarding automations

Good for: freelancers who market themselves with video or run a podcast.

How to keep the stack small

• Review subscriptions monthly. For each tool, ask whether you used it this month for paid work or for marketing. If not, downgrade or cancel.
• Avoid overlap. Many tools now include some AI features. You rarely need three separate writing assistants.
• Protect client data. Check each tool's data and privacy settings before you paste client material into it.
• Write prompts down. Keep your best prompts in Notion or a document so the value stays with you, not with a specific tool. Prompts like the proposal draft prompt work in any of the assistants above.

The best stack is the one you use every week. Start with the jobs, add tools slowly, and drop anything that has not earned its place.
