Caption Wizard AI

Web application built with Next.js and DeepSeek to generate on-brand social captions in seconds.

Problem

Creators and marketing teams needed consistent content output, but writing fresh captions manually was slow and repetitive. The project goal was to automate caption ideation while keeping quality and brand voice high.

Solution

Built end-to-end in Next.js with a fast responsive UI and server-side API routes for model calls. Integrated DeepSeek to generate caption options from keywords, context, mood, and target platform. Added tone, length, and format controls, plus re-roll and refine actions, caching hints, graceful retries, and safety checks for brand-safe language.

Outcomes

Reduced caption creation time from minutes to seconds. Improved consistency across platforms with stronger tone coherence and variation. Delivered a scalable base for multilingual captions, reusable templates, and future scheduling integrations.
