The AI category is the noisiest corner of software right now, and the hardest to shop in. A product calling itself "AI-powered" might be a fine-tuned model with real evaluation behind it, or a prompt template with a pricing page. Both look identical from the outside.
What we list here splits roughly three ways. Model APIs and infrastructure — the layer you build on, billed per token or per call. AI-native applications — products where the model is the whole point, not a bolted-on sidebar. And AI features inside conventional tools, which we usually file under whatever the tool actually does instead.
The useful question is not whether a product uses AI. It is what happens when the model is wrong. Tools that answer that question well tend to show their working: confidence scores, source citations, an obvious path to a human. Tools that dodge it are asking you to trust a black box with your workflow. If you are building in this space rather than buying, our piece on vibe coding covers what the flood of AI-generated software means for anyone trying to stand out in it.
What to look for
- Where the model actually runs
Hosted API, self-hosted weights, or on-device changes everything downstream — your latency, your per-unit cost, and whether your customers' data leaves your infrastructure. Products that are vague about this are usually reselling someone else's API.
- Pricing that survives success
Token and credit pricing is fine until volume arrives. Model the cost at ten times your current usage before you commit. Our breakdown of SaaS pricing models covers why usage-based billing punishes exactly the customers you most want.
- Evaluation, not demos
A polished demo proves the happy path works. Ask what the failure rate is on your kind of input, and whether the vendor measures it. Teams that run evals will tell you the number; teams that do not will tell you about the demo again.
- Model lock-in
If the product wraps one provider with no way to swap, you inherit that provider's outages, price changes, and deprecations. Portability is worth paying a little more for.
