A chat app hides your work inside a thread. Run Claude inside a free code editor and keep your whole client book as files you can see, open, and keep, with every edit approved before it saves.
A free code editor plus the Claude extension. No API key, no coding required to use it as a file-based workspace.
A clean table, one row per client property, built from a plain-text list you paste in.
Paste income and expenses and let Claude add them to a running log and flag any shortfalls against the tracker.
Claude reads the tracker and the log and drafts a one-page update as a new file in the same folder, pulling only from what's there.
Update my income log for [month]. Here is what came in and went out: [figures]. Add this as a new section, then compare against the tracker and tell me which properties are short or missing, and by how much.
Nothing is changed silently. You stay in control of every file.
Almost none of the work here is code. The editor is simply a better workspace than a chat thread for files that persist.
