What does a credit buy?

Ask Sidekick to turn Tuesday's call notes into the engagement letter, to draft the reminder when a retainer invoice runs late, or to answer a question about a client, and that uses credits. Doing things yourself never uses credits. Only the AI's work does. Starter includes 40,000 credits a month and Pro 120,000; extra packs start at $10 for 10,000 and never expire.
