Custom AI wins when the job is yours: your voice, your workflow, your people, the way your business actually runs on a Tuesday. Off-the-shelf SaaS wins when the job is a commodity, the kind of thing a thousand businesses do identically and nobody needs a personality for (payments, email delivery, taxes, the law).
The test: if a tool showed up in the last couple of years and mostly talks to an AI on your behalf, you can probably create it yourself instead of renting it. Keep whatever earns its keep. Replace the one that hurts to pay for.
The trade: creating your own costs some time at the start, an AI subscription you probably already pay for, and from then on you are your own help desk.
Who's answering: RJ Redden has been coaching people about technology since 1998 and working with AI since 2020. She runs Black Belt Bots™ and NO BS AI™, and she has replaced her own events platform, the tool that makes her newsletter images, her writing desk and most of her studio's admin with AI tools she created herself, without writing a line of code. This page carries her receipts.
"Custom" means an AI tool you create yourself. "Off-the-shelf" means the software subscription.
| The axis | Off-the-shelf SaaS | Custom AI | Who wins |
|---|---|---|---|
| What it costs | A monthly fee, forever, with a tier above you | An AI subscription you likely already have, your hours up front, then pennies per use. My events site costs me about four dollars a month, which is what I pay Cloudflare | Custom |
| What you need before you start | A credit card | An AI subscription, a free afternoon, and the nerve to describe what you want in plain English | Off-the-shelf |
| Fit to how you work | Made for the average customer, or for a company of four hundred | Shaped around how you actually work | Custom |
| Your voice | Theirs, with a few settings to pick from | Yours, tuned sentence by sentence | Custom |
| Who owns the work | Lives on their servers, under their terms | Yours, with a copy on your own machine | Custom |
| Who moves the buttons | They do, whenever they like | You do, and only when you decide to. (The AI behind it can still change. But your tools and your copy stay put.) | Custom |
| Features you'll never touch | Dozens, and you pay for every one of them. Mine had forty | The four you actually use | Custom |
| Time to first use | Today. Card in, logged in | An afternoon to a few days for your first one. After you get a workflow, minutes. | Off-the-shelf |
| Upkeep | Theirs, included in the fee | Yours, when something changes. Mostly small, occasionally an afternoon | Off-the-shelf |
| When it breaks | A help desk, a status page, somebody else's problem | You, your AI, and your people | Off-the-shelf |
| Heavy, regulated jobs | Payments, email delivery, accounting, anything the law cares about. They've spent years on the boring part | Possible, and the wrong hill to die on | Off-the-shelf |
| Walking away | Export what they allow, in the format they allow | The tool is already on your machine. If the AI behind it changes, you swap the AI, and keep the tool | Custom |
Custom AI wins seven to five. Off-the-shelf software is faster to start, easier to keep, and the right answer for anything with a lawyer attached. Custom wins everything that is actually about you.
Custom AI wins when the job is about you: your voice, your workflow, your customers, the way you actually work. You get the four features you use and none of the forty you don't, a tool shaped around your own workflow, a copy on your machine, and nobody who can rearrange it or reprice it next quarter.
Nearly every AI tool sold to small businesses right now is a pretty front door with an AI behind the curtain doing the actual work. The secret is that you probably already have an AI subscription, and making a front door for yourself isn't that difficult.
Off-the-shelf wins when a thousand businesses do the exact same job the exact same way, when getting it wrong has a lawyer attached, or when the vendor's whole value lives in the boring, heavily tested part: payments, email deliverability, accounting, anything with the word compliance standing near it.
Off the shelf software also wins on speed and upkeep. A credit card gets you in today, and when it breaks there is a help desk.
Mine are the only numbers I'll give you, because they're the only ones I've measured. My events site costs me about four dollars a month, which is what I pay Cloudflare to host it.
Before I had my own, I was paying for four different image tools at once, a couple hundred dollars a month between them.
Every time I had an image prompt, I ran it through all four and kept the best one. Now I have one tool, set up the way I want it, and I don't need the other four. It costs me three or four cents an image, so at one a day, call it a dollar and change a month.
Then I made a movie machine. A five minute movie with voiceover, music and sound effects costs me about eight dollars.
Add your AI subscription, your API costs, and your hours, and that's the whole bill. Anybody who quotes you a universal number is selling something, and should be avoided.
Yes. I don't code. Everything I run was created by describing what I needed to an AI, in plain English, and sending it back when it was wrong. That's the process.
More than forty chatbots, an events platform, the tool that makes my newsletter images, a writing desk, a movie studio, and the dashboard I run my whole studio from. Zero lines of code written by me.
A student in my NO BS AI™ class who had just watched my events tool work had his own version running inside an hour. The first tool takes an afternoon to a few days.
Five questions, in order.
Does it hurt to pay for?
Is the hard part behind the curtain the AI, or them?
Do a thousand businesses do this exact job identically?
Would you be furious if they moved the buttons?
Could you and your AI have a rough version running by Friday?
Five yeses = create it. Payments, taxes, or the law = rent it. Works fine, bores you, costs a few dollars = leave it alone and go write something.
My events software wanted seventy dollars a month, forever, for the privilege of inviting my own people. I asked my AI to create the version I actually needed, and events.blackbeltbots.com is mine now.
Eight hundred and forty dollars a year for the subscription, versus about forty-eight dollars a year to run my own (four dollars a month, which is what I pay Cloudflare).
A student who watched it work had his own running inside an hour, then moved his website to cheaper hosting and saved an extra four hundred dollars a year.
The scar that made me stubborn: a set of custom assistants I tuned over months inside a rented AI tool vanished when I cancelled, came back when I paid again, and vanished a second time when the company changed the rules. It's theirs now. I'm still bitter.
Find one person you trust, and take their class. That's my honest answer, and it's the only answer on this page that isn't about software.
The loudest voices in AI right now are the hype bros, who will sell you a course before you've finished the sentence. Then there's the doomsayers, who will tell you that using AI destroys artists.
Neither one has asked a single question about what you make. So skip them both. Look for somebody who has actually created their own tools, uses them every day, and will let you watch. Then sit in their room and create one thing with them, with your own hands.
Bring one subscription with you. The one that hurts, the one you sigh at when you see the bill. A class with no project is a lecture. A class with that subscription in your lap is the first tool you ever owned.
Mine is NO BS AI™, where creatives and entrepreneurs create their own AI tools, no code required, with me riding shotgun.
Take a free week. Day one, you write a one-page document that teaches your AI how you sound and what it may take off your desk. Day two, you create one small tool, no code, yours to keep.
There's a live session on Thursday with me in it. It's a free week on a paid membership: a card goes in at checkout, and on day eight it becomes $97 a month unless you cancel first, which you do yourself, in a couple of clicks.
Whatever you created in the week stays yours either way. You've got nothing to lose.
