Read our full methodologyHow to choose knowledge base
The right tool depends on your channels, volume and how much you want to automate. Use this framework to narrow the shortlist above before you start a trial.
- Channels - which of live chat, email, social and voice you actually need to unify.
- Automation - how much you want an AI agent to deflect before a human steps in.
- Integrations - whether it fits your CRM, help center and e-commerce stack.
- Scale and pricing - per-agent versus per-resolution costs as your volume grows.
How much does knowledge base cost
