You don't need another £50/month subscription gathering dust.
Most founders pick AI tools the wrong way. They see a demo, get excited, sign up, then realise it doesn't fit their workflow. Money wasted. Time wasted.
Here's how to choose an AI tool that actually works for your business.
Start With One Problem, Not a Platform
Don't look for an "AI platform" that does everything.
Pick one specific problem you want to solve. One task that takes too much time or causes friction.
Examples:
- Writing social media replies takes 2 hours a day
- Reviewing CVs for each role takes 4 hours
- Drafting client emails eats into billable time
If you can't name a single clear problem, you're not ready to buy an AI tool yet.
This is how we built ReplyIQ at Marvanova. We didn't create a social media management suite. We focused on one pain point: generating smart replies fast. That's it.
Map Your Current Workflow
Before you search for how to choose an AI tool, write down how you currently do the task.
What steps are involved? Where does it slow down? Which part could automation handle?
Let's say you're screening tenancy documents. Your workflow might look like:
- Open the document
- Skim for red flags
- Check specific clauses manually
- Flag issues for follow-up
- Write notes for the client
An AI tool should slot into this process, not replace it entirely. In this case, steps 2 to 4 could be automated. That's where a tool like TenancyAI fits.
If you can't see where AI fits in your workflow, the tool won't stick.
Test Before You Commit
Never pay for an annual plan upfront.
Look for tools with free trials or monthly plans. Use them in real scenarios, not hypothetical ones.
During the trial:
- Use it for actual work, not toy examples
- Track how much time it saves (be honest)
- Note any friction points (does it slow you down?)
- Check if it integrates with what you already use
If a tool doesn't offer a trial, that's a red flag. Move on.
At Marvanova, we offer demos and trial access for PropFlow because we know it has to fit your process before you spend money.
Calculate the Real Cost
The price on the website isn't the full cost.
Factor in:
- Setup time (how long to configure and learn?)
- Integration work (does it play well with your existing tools?)
- Maintenance (do you need to keep training it or tweaking settings?)
- Opportunity cost (what else could you spend that money on?)
A £20/month tool that takes 10 hours to set up isn't cheap. A £100/month tool that works instantly might be.
Ask yourself: if this tool saves me 5 hours a month, what's that time worth?
If you bill at £100/hour, a tool that saves 5 hours pays for itself at £500/month. Anything under that is profit.
Ignore Features You Won't Use
Marketing pages love feature lists. You don't need them.
Most tools have 20 features. You'll use 3.
Focus on whether it solves your one problem well. Ignore the rest.
Example: if you need an AI tool to shorten candidate CVs for faster review, you don't care if it also writes job ads or schedules interviews. That's scope creep.
Lucuma, our recruitment shortlisting tool, does one thing: scores and ranks CVs against job descriptions. We didn't bolt on 15 other features. That's intentional.
More features often means more complexity and more cost. Stick to what you need.
Check Who Built It
This matters more than you think.
Is it built by a solo founder who uses it themselves? Or a VC-backed startup burning cash to grow fast?
Solo founder tools tend to stay focused and affordable. VC-backed tools often pivot, raise prices, or shut down when the money runs out.
Look for:
- Active updates (when was the last feature release?)
- Responsive support (can you reach a human?)
- Clear pricing (no "contact us for a quote" nonsense)
At Marvanova, we build tools we'd use ourselves. That's why they stay simple and solve real problems.
Start Small and Stack Later
You don't need 5 AI tools on day one.
Pick one. Use it until it's second nature. Then add another if needed.
Stacking tools too early creates complexity. You spend more time managing subscriptions than working.
Our advice: solve your biggest time drain first. Let that tool prove its value. Then move to the next problem.
If you're a letting agent, start with PropFlow to manage tenancies. If you're a recruiter, start with Lucuma to shortlist CVs. Don't try to automate everything at once.
Know When to Walk Away
Not every problem needs an AI tool.
Sometimes a spreadsheet works fine. Sometimes you just need a better process.
If you've followed this framework and still can't find a tool that fits, don't force it. Save your money.
The wrong tool is worse than no tool. It creates busywork, confuses your team, and drains your budget.
Be willing to walk away if it doesn't click.
Final Checklist
Before you buy, ask yourself:
- Does this solve one clear problem?
- Can I test it with real work first?
- Does it fit my workflow without major changes?
- Is the cost justified by time saved?
- Do I trust who built it?
If you answer no to any of these, don't buy.
Choosing how to choose an AI tool isn't about features or hype. It's about fit.
Pick tools that slot into your life, not ones that demand you rebuild your process around them.
