Does it connect to the tools you already use — your editor, browser, Slack, Google Workspace or API?

When free is enough
10 of these 11 ai search engine tools offer a free or freemium plan (Liner is the one we'd start with). Free tiers suit light or occasional use, testing a workflow, or personal projects — though they usually cap usage, features or output quality.
When to go paid
For heavy or professional ai search engine work, a paid plan like Kagi's buys higher limits, team collaboration, priority support and advanced features. If a tool is core to your daily work, the subscription usually pays for itself in time saved.
