Right now, we're living in one of the best times to start a solo business. With AI automation, low-code platforms, and software as a service tools, you can build a profitable online business without needing a massive team or investment. But what should you actually build? This is often the hardest part to figure out.
So, in this post, I'm going to be sharing seven powerful SaaS ideas that you can start building right now as a solo founder without writing a single line of code. Some of these can be built using AI tools, automation platforms, or simple APIs, and they all have huge potential for recurring revenue.
1. AI-powered writing assistant
Our first tool is an AI-powered writing assistant. The market opportunity here is pretty huge as the demand for AI-generated content continues to explode and businesses are constantly looking for ways to streamline their content creation. But the idea is we can create a niche-focused AI-powered writing assistant.
Instead of competing with ChatGPT, we can focus on specific industries. For example, it might be a legal AI writer that helps lawyers draft contracts, policies, and legal templates. It could be a real estate listing generator using an AI-powered tool that generates engaging property descriptions, or an SEO-powered blog generator where we're creating long-form, search-optimized articles in bulk based on keywords.
Our tech stack here could be using GPT-4, Claude, or open-source LLMs with a simple web app using tools like Bubble.io or Webflow with integrations. It's going to work because businesses always need industry-specific AI tools that produce more accurate and compliant content.
And the existing tools out there are good, but often they're not specific enough. And as AI improves, some of these tools that were created 2 or 3 years ago are no longer up to scratch with customer expectations for instant results.
2. Automated cold email and LinkedIn outreach tools
Our next SaaS idea is an AI-driven tool that automates personalized cold emails and LinkedIn messages. The market opportunity is massive because anything to do with sales and marketing that drives revenue is going to be big.
Sales teams and founders spend hours reaching out to leads manually. We can integrate AI to analyze a prospect's LinkedIn profile and then craft a unique email based on their LinkedIn description and any post they've made recently. We can then also create automated follow-ups to increase our reply rates and even add lead scoring to show which prospects are most engaged.
Our tech stack here might include OpenAI's API or Claude, but we could also lean on tools like Clay, which already do this very well. It isn't quite accessible to everyone, especially sales teams who might find it a little tricky. We also want to incorporate a web scraper and LinkedIn integration to pull it all into a single platform.
The reason this works is it saves time and increases sales conversions, which is a massive pain point for businesses. And compared to tools like Clay and other AI SDR tools out there, if we create a very specific point solution that solves one key problem—such as ensuring the copy is absolutely nuclear and converts every single time when someone clicks on an email—then you're going to be rewarded with buyers.
3. AI-powered video editing and repurposing tool
Number three on our list is an AI-powered video editing and repurposing tool. Video content is absolutely booming, but editing continues to be hugely time-consuming and existing products out there like Opus Clip or Captions don't allow a huge amount of customization or catering to how individual editors like to edit their own clips.
Our idea here and unique selling point is building an AI tool that automatically repurposes long-form content into Shorts clips, but unlike tools like Opus Clip, it actually maps it to the way that we like to edit ourselves. We're training that on a custom AI where we're uploading the format, the structure, and things like hooks.
So, as well as doing things like auto-cutting and captioning and AI-generated viral hooks, as well as social media auto-rolling, we might want to add in things like our own custom assets that people can upload their own files to. Then it becomes hugely personal and customized to the way a specific video editor works.
We can also make it a lot faster than the competition and compete on pricing where those tools can be quite expensive initially.
Our text stack will use a combination of tools here, including transcription AI tools like Whisper AI, as well as FFmpeg for video processing and OpenAI's API for text summarization and diarization. The reason this works is that content creators and businesses always need faster ways to repurpose content across multiple platforms.
And the existing AI SaaS tools out there often don't cater to the needs of an individual editor. So, if you double down into a niche—let's say educational YouTube videos or tech YouTube videos—and really structure editing around those particular content types, you're going to win in that niche and then you can expand outside and tackle more problems and more creator types.
4. No-code AI chatbot for small businesses
Number four on our list is a no-code AI chatbot for small businesses. Now, most small businesses don't have chat support and they tend to lose leads because of slow responses, and existing tools like Intercom or Gleam aren't that good at personalizing things and they're also quite expensive.
Our idea here is a plug-and-play chatbot that's able to answer FAQs automatically using AI and pulling information from a company's website or their knowledge base. It could also do things like booking appointments and align with marketing and sales. It could also be an omni-channel tool that integrates with WhatsApp, Facebook Messenger, and other websites using APIs.

Our tech stack could be something like OpenAI's API. We could also use Typeform for collecting information, the WhatsApp API, and other APIs that could plug in here. The key benefit here is that a lot of small businesses just can't afford to handle the volume of customer inquiries.
Our USP is that small businesses can't afford full-time customer support but still need to handle inquiries fast. The AI's ability to respond in the tone and language of that business is absolutely critical for ensuring customers are happy and you're not losing out on any business.
5. AI-powered resume and cover letter generator
Number five on our list is an AI-powered resume and cover letter generator. Job seekers struggle to craft compelling resumes that pass ATSs, also known as applicant tracking systems. There are a lot of these AI tools out there. What we want our tool to do that stands out is the ability to scrape and scan job descriptions and then tailor the resume and cover letter automatically.
We want to be able to suggest powerful action verbs and achievements and also check grammar, structure, and formatting. Most importantly, compared to other tools out there, we don't want this to sound AI-generated.
We want to train automatically on the person’s tone of voice, which is absolutely critical because a lot of hiring managers are simply complaining that they can spot AI-generated resumes in a second. So what we're doing here is plugging in Claude or OpenAI's API and then using something like a RESTful API for parsing PDFs to text, as well as tools like Canvas API for creating beautiful templates, which again stands out against the competition.
The reason that this works is that the job market is incredibly challenging at the moment and more and more people are looking for jobs and want to stand out. By building this tool, it's giving job seekers a competitive edge and personalizing things while avoiding AI detectors.
6. AI-powered subscription cancellation and refund assistant
SaaS number six is a really great one: an AI-powered subscription cancellation and refund assistant. There's a huge problem here with people spending billions on subscriptions that they just forget to cancel.
Our idea is a one-click cancellation tool that detects all active subscriptions you might have or that a company has, by scanning things like emails or bank transactions from those companies. It then automates cancellation requests to their customer support and negotiates refunds on behalf of users automatically, where people might not think to do that.
Our tech stack includes email parsing using Gmail's API, Stripe's API, and customer-service automation using OpenAI's API and Claude. This works because people hate dealing with customer service and nobody really wants to lose money on unwanted subscriptions, but they might miss the opportunity to request a refund or simply not know how to do it.
7. AI-powered niche marketplace
Number seven on the list is an AI-powered niche marketplace. The market opportunity here is huge, with Airbnb, Uber, and Etsy proving that niche marketplaces work, but most require high startup costs. Our AI SaaS idea here is to create an AI-driven micro-marketplace in a specific niche.
This might be something like AI tutors where you connect learners with AI-powered language tutors, a freelance AI editors marketplace for AI-assisted content writers and editors, or AI-powered event planning where AI helps people find venues, caterers, and photographers rather than working with an expensive human.
The tech stack here might be something like Sharetribe, a no-code marketplace builder, and AI APIs for personalization. It's going to work because the future is AI-powered marketplaces that make service discovery much easier.
Bonus tip
As a quick bonus point here, a lot of the ways to win are in the execution and validating the need for your idea. Here's how to do that.
First, set up a landing page in something like Webflow or Carrd, or even Typeform, that allows us to collect information from users. Then set up a waitlist form and use tools like ConvertKit or Typeform to collect emails from people who land on that waitlist to gauge interest.
What I've done in the past is run a small Facebook or Google ads campaign, locking in total spend to around $200 over a weekend and driving an ad that focuses on the people we might be selling to.
So, for example, for our AI video editing tool, we might target small one-person video editors or one-person solo creators and run that aggressively with our USP that stands out against tools like Opus Clip, CapCut, or Captions, or whatever else you're going up against.
Once you've validated that idea and you've got a waiting list of, I would say, at least 200 people on there, we can start building out our MVP. Starting off with a no-code tool, you could use tools like Bubble.io or Airtable and Zapier with some automation linked up. And then if people sign up and begin to engage, you've got your winning SaaS idea. Then it's all about doing as many customer interviews as possible, optimizing that user interface, and then adding pricing to see if people are willing to pay.
