HappySupport, The Help Center That Updates Itself

100% free

Create help center articles in seconds with the intelligent step-by-step recorder.

Key features

Self Updating Knowledge Base
Step-by-step recorder
Auto updating UI screenshots

Cons

Pricing climbs steeply for a docs tool: the entry Starter plan is 129 EUR per month yet caps you at one user, 50 articles, and 100 searches, so team access plus multi-repo Git updates forces the 399 EUR Professional plan, with the Scale tier at 899 EUR.
The self-updating and article-flagging capability is built around connecting a GitHub or Git repository to detect UI and code changes, so non-technical teams or those not hosting their product on Git get much less of the core value.
