7 Micro-SaaS Ideas You Can Build Today With AI (No Coding Required)

Micro-SaaS is the sweet spot between a side project and a real business. Small enough for one person to build and maintain. Focused enough to charge real money for. Here are 7 ideas with high demand and low competition.

1. AI Invoice Generator for Freelancers

Build a tool that generates professional PDF invoices from simple inputs. Add VAT calculation, payment terms, and email delivery. Charge £9/month. Build it with Lovable.dev in an afternoon.

2. Local Business Review Manager

A dashboard that aggregates Google and Trustpilot reviews, flags negatives, and drafts AI responses using Claude. Sell to restaurants, salons, and tradespeople at £29/month.

3. AI Proposal Writer for Freelancers

Input client name, project brief, and budget. Get a polished proposal PDF in 30 seconds. Freelancers spend hours on proposals — they'll happily pay £19/month to save that time.

4. SEO Blog Brief Generator

Enter a keyword, get a detailed blog brief: target audience, subtopics, word count, competitor insights, FAQs, and internal link suggestions. Content agencies pay £49–£99/month for tools like this.

5. Client Onboarding Portal

A white-labelled client portal where agencies can onboard clients, share documents, collect approvals, and track project milestones. Charge £49/month per agency seat.

6. Social Media Caption Scheduler

Input your product/brand voice, get a month of Instagram, LinkedIn, and X captions in one click. Schedule via Buffer API. Small businesses and personal brands pay £19/month for this.

7. AI Terms & Privacy Policy Generator

Build any of these on Lovable.dev and use Claude AI to write the marketing copy, help desk docs, and onboarding emails. The entire operation runs on two tools.
