Bringing Brand Consistency to Finance Slides — with AI

An AI-driven tool that helps investment bankers maintain brand consistency in their slide decks. The flow lets a manager upload examples of how the company usually writes, define corporate tone-of-voice, and then the team uses a PowerPoint add-in to make their slide text match that writing style.

/ opportunity

How might we enable finance teams keep presentations on-brand without endless manual reviews?

/ my role

I collaborated with the PM and development team to design and launch an AI-driven tool that helps finance teams keep their presentations aligned with the company’s writing style. I designed the full Tone of Voice and AI prompt set up flow, ensuring smooth hand-off with detailed user flows and specifications for devs.

I led UX flows, UI design, responsive layouts across both the manager dashboard and the PowerPoint add-in used by employees, ensuring a polished and consistent experience.

Step 1: Setting Tone of Voice

Manager uploads text docs that AI analyzes & generates Tone of Voice which employees apply to their presentations.

Step 2: setting up prompts

Manager sets up prompts that help employees refine their slides. Examples of prompts are 'Summarize a text' or proofreading a text.

Step 3: Fine-tuning prompt list

Manager adjusts AI prompts which employees apply to docs

step 4: Applying tone of voice to the slide text

Employees select a prompt to apply tone directly in slides.
