How we picked these ai chatbots
We evaluated each candidate on three fronts: feature depth, pricing clarity, and fit for the startup use case. Feature depth meant looking at whether the tool could handle more than just chat — like code generation, research, or integrations. Pricing clarity mattered because startups need to budget carefully; we favored tools that either offer transparent pricing or a free plan. Fit for the use case was about how easily the tool could be adopted and scaled, from browser extensions to team plans. We also considered reliability, preferring tools with strong ratings and proven track records. None of these picks require a lengthy setup, and all can grow with your team.
