FAQ
Frequently asked questions
How does ChooseOS pick the best ai assistants tool?
We don't. Instead, we publish a fixed rubric — pricing, features, integrations, security, implementation and total cost of ownership — and score every ai assistants vendor against it using primary evidence. The 'best' answer changes with your company size, industry and use case, which is why every comparison page lets you set your context.
Are ChooseOS's ai assistants comparisons paid for?
No. Vendors can pay to maintain their profile, publish an official perspective and add product videos and CTAs. They cannot pay to change scores, verdicts, criteria or rankings. Every commercial arrangement is labelled on the page.
How often is this category updated?
Pricing is re-verified quarterly. Feature availability, security posture and integrations are reviewed at least twice a year and after any significant vendor release. Each page shows its last-reviewed date and change history.
How do I request a new comparison?
Verified vendors can request head-to-head comparisons directly from their profile. Buyers can suggest comparisons free — the strongest signal is buyer intent, so tell us which two products you're actually evaluating.
