Instacap

What it does

- UNIQUE SELLING POINT: Instacap bridges the “platform gap” that with existing AI-based caption products: current solutions are not mobile-first, but users prefer mobile to store images and post to their social media.
- IMPACT: By lowering the barriers to posting, users will engage more with followers via reacts, comments, DMs. This can help repositioning existing social media from a doom-scrolling service to a more peer-based content feed.
UX DIFFERENTIATORS: Instcap is Progressive Web App (PWA) built on React, to enable a mobile-first experience without app store download. Users can still experience native-like features such as splash screens, hidden browser bars, and fast rendering.
BEST PRACTICES: Uses a serverless architecture enabled by Firebase Cloud Functions and Remote Config. This lightweight approach improves performance by performing intensive operations offboard. At the same time, the developer can update sys. instructions & model configs without redeploys to adapt to the fast-evolving AI space.
- GEMINI API USAGE: Uses few-shot techniques based on a curated caption dataset. Leverages Gemini’s multi-turn conversation ability to append previous context, so that the user does not see duplicate captions in a session.
- V2 features: Consider transitioning from few-shot to fine-tuning based on dataset size, allowing context injection for non-obvious terms (e.g., “New Year’s Eve”), and enhancing account features like saving captions and tracking caption generation.
