Do I need a paid Claude.ai plan to try this?

No. The free tier on claude.ai gives you Claude Sonnet, Artifacts in the side panel, web search, and roughly fifty messages a day on a long context window. That is enough to brief a tool, iterate it five or six times, and download what you build. The first time you run a four-corner brief, none of the free-tier walls will bite.

What kinds of admin jobs work best for this?

Anything you would have asked a junior or an admin person to set up. Quote templates, deadline reminder systems, lead-qualification scoring sheets, onboarding checklists, booking-confirmation email generators, simple internal calculators. The pattern is straightforward: a tool a single non-technical user opens in their browser and uses without training.

What if Claude builds something that does not work the first time?

Tell it what is wrong in the next message, in plain English. 'The deadline calculation is off by one day for February.' 'The currency formatting should be R 1 234,56, not R1,234.56.' Claude updates the same Artifact in place. The free-tier daily message limit gives you plenty of room to iterate five or six times before the limit hits.

Can I use this for client-facing work, or only internal admin?

Both, with one caveat. Client-facing output should be voice-checked by a human before it ships. Claude is excellent at building internal tools and first-draft client-facing copy, but the polish that makes a deliverable feel like yours, rather than a generic AI output, still has to come from you. The four corners get you to a draft eighty percent of the way there. The last twenty percent is editorial.
