Professional Work — Moody's

Drafting credit memos, without locking a bank into one system.

A chat + canvas AI tool that drafts credit memos starting from a bank's own template — designed to work across loan origination systems, and to hand back a polished, bank-branded document at the end, not just an unfinished draft.

This is enterprise work under NDA. The screens below are from a recreated, interactive prototype built to demonstrate the pattern — not real product screens, client data, or Moody's branding.

Writing the same memo, from scratch, every time.

A credit memo justifies a lending decision — ratios, borrower history, a recommendation, in the format a credit committee expects. It's repetitive work: analysts reconstruct a familiar structure by hand for every deal. And banks run different origination systems and already have their own memo templates, so a tool that forced a generic format or worked in only one system would start a fight it didn't need to have.

The agent drafts straight into the bank's own template. Flagged figures block that section from sign-off until resolved.

Chat to direct, canvas to verify.

The chat panel takes plain-language instructions and corrections. The canvas is the actual memo — read and edited section by section, not a wall of text taken on faith. Anything the agent isn't confident about is flagged in place, and that section can't move to sign-off until the analyst resolves it.

Starts from the bank's template

Upload a format or pick a saved one; the agent drafts into that structure.

LOS-agnostic by design

Sits alongside whatever loan origination system a bank already runs.

Two-stage sign-off

Analyst approves first; a credit officer signs off after.

Exports to a finished document

Once approved, the memo compiles into the bank's own branded format.

A plain-language correction in chat resolves a flagged figure directly in the canvas — no separate edit mode.

Prototyping the chat-canvas split itself.

The core question was how to split conversation from document so the analyst always knows where to intervene. Rapid prototyping tested an all-chat version, an all-canvas version, and combinations between — landing on chat-directs / canvas-verifies. The same iteration surfaced a smaller decision: a single uniform flag felt too blunt once tested side by side, leading to distinguishing a routine "needs review" from a genuine data conflict.

A tool that travels with the bank, not the platform.

Being LOS-agnostic — rather than a feature bolted onto one origination system — makes it useful to a much wider set of banks from day one, and keeps the credit team's workflow independent of whatever core system the institution runs.
