PERSONAL FINANCE OPERATING SYSTEM
Your money, with a second pair of eyes.
LedgerLab gives your browser agent a structured view of your mock ledger — so it can spot waste, model a move, and bring the decision back to you.
It's not another budgeting app that nags you — it's a co-pilot that reads your ledger, spots the waste, and hands you a plan to approve.

THE CO-PILOT LOOP
Clarity in. Confidence out.
Structured tools turn a messy money moment into a shared decision — with the person always holding the keys.
🤝
Plan together
The agent simulates a reallocation and hands you a concrete proposal — not an invisible action.
- Compare projected budgets
- Keep the trade-off visible
🛡️
Stay in control
Writes land in the dashboard as they happen — with a human approval gate and an undo button.
- Approve consequential changes
- Reverse the last agent write

Nothing is a one-way door.

TRUST BOUNDARY
Approval is the feature.
The agent can prepare the move. Only you can make it real.
HUMAN CHECKPOINTTool map: reads inform the proposal, simulation creates a reviewable plan, and writes only happen after a human decision.
TRY THE HUMAN-AGENT LOOP
Meet the Agent Playground.
Pick a preset prompt and watch the same tool paths used by an in-browser agent run against fictional LedgerLab data.
This is a preset mock agent — no real AI, no backend, no banking connection.
Choose a preset above to send a structured tool call.
The result will appear here as compact JSON — just like an agent response.
ACTIVITYWaiting for a preset agent call…
This Playground simulates an in-browser agent calling LedgerLab's WebMCP tools. In ChatGPT's in-app browser, the same tools fire from your natural language — no chat box needed here.
FROM THE FUTURE OF FINANCE
Less nagging. More “aha.”
It caught three subscriptions I had mentally filed under “probably fine” — then let me decide what to do.

The proposal card is the magic. I can see the trade-off before I let anything touch my budget.

Finally, an agent that knows “help me” does not mean “make every decision for me.” ✨
