Challenge
WellSaid Labs turns scripts into human-quality voiceover modeled on real, licensed voice actors — built for teams producing training, marketing and product audio at scale, with commercial rights included. The main delivery challenge was to give users sensitive health information presented calmly, clearly, and without adding cognitive load, while keeping Script, Voice, and Direct consistent across the complete journey. We framed the engagement around the smallest production-worthy flow first, then expanded the scope without weakening the underlying component and data model.

How we built it
We began by mapping the user journey and the boundaries of the AI: what context it receives, what it may return, and where deterministic application logic must stay in control. We then built Script, Voice, and Direct as small end-to-end slices, connecting the interface to the data and model layers early so the team could test real responses instead of static mock-ups. Prompt, validation, and fallback behaviour were refined alongside the product UI. The main implementation used Next.js (App Router), React, TypeScript, and Tailwind CSS, with typed contracts keeping the JavaScript stack consistent across the product.
03
Delivery
The delivered scope brought Script, Voice, Direct, and Refine into one coherent production-ready product experience. Model output, product logic, and user feedback are separated clearly, which makes the AI easier to evaluate and evolve. For WellSaid Labs, the practical result is a product that communicates its value quickly while giving the team a maintainable base for continued delivery in health & wellness.
