Custom AI Tool or Off-the-Shelf? A Simple Way to Decide
Sometimes a $20 subscription is the right answer. Sometimes it's a custom workflow built around your systems. A plain-English framework for choosing.
By InnoStak Team
"Should we build our own AI tool?" usually comes up after an off-the-shelf tool almost works. The honest answer is often "not yet," and sometimes "yes, and here's the small version."
Start with off-the-shelf when...
- The task is common (email, notes, writing, scheduling).
- Your data already lives in mainstream tools with AI features.
- You're still figuring out what "good" looks like.
- One or two people will use it.
Cost: low monthly fees. Risk: low, since you can cancel.
Consider custom when...
- The task depends on your process, rules or data that no product knows.
- You're copying information between systems by hand every day.
- Several people do the same task differently and quality varies.
- Mistakes are expensive and you need approvals and logs your way.
Cost: upfront build plus upkeep. Risk: higher, so start small.
