BIRTHDAY PARTY: Lemonade πŸ‹

πŸ† 2ND Place Winner - HackIsland 9.0 Lenovo Spring 2026

Lemonade is an AI-driven web application that empowers creators to build high-impact pitch decks and assists reviewers in evaluating them through an objective, data-backed framework.


πŸš€ Project Overview

Lemonade is a comprehensive pitch-refinement ecosystem designed to bridge the gap between a great idea and a successful presentation.

πŸ‹ The Problem

  • Ineffective Pitches: Roughly 80% of presentations fail to deliver their objective, and 99% of startup pitch decks fail to receive any funding.
  • Complexity: Aspiring creators often struggle to build effective decks, and existing company trainings can take hours to complete.
  • Reviewer Bottlenecks: Busy managers are often overwhelmed, leading to delayed reviews and decisions made based on assumptions.

πŸ’‘ Our Solution

Lemonade streamlines the pitching process by serving as an intelligent bridge between the Creator and the Reviewer.

The application is built on three core pillars: AI-Guided Creation, Video Performance Analysis, and Comparative Review.


✨ Key Features & Benefits

Feature Description Benefit to the User
Guided Pitch Builder Continuous interaction between the user and the LLM to collect information. Walks you through building a perfect pitch without needing hours of training.
PITCH+H Framework Grades pitches against a rubric: Premise, Idea, Clarify, Tell, Help, and Heart. Ensures all critical narrative elements are present for maximum impact.
Review Weights Allows reviewers to toggle the importance of specific rubric categories (e.g., weighing 'Heart' over 'Premise'). Tailors the evaluation to the specific goals of the organization or event.
Video & Speech Analyzer Reviews uploaded videos to judge speech, pauses, word count, and tone. Provides feedback on the 50% of investor attention that relies on oral delivery.
Context-Aware Refinement Uses project-specific context and previous drafts to suggest deeper improvements. Moves beyond generic advice to provide highly specialized technical or creative feedback.
Shareable Review Sessions Generates unique links for reviewers to collaborate on evaluations. Streamlines the decision-making process for hiring committees or judging panels.
Local State Persistence Utilizes local storage to save progress, draft states, and session data. Ensures no progress is lost if a tab is closed or a connection is interrupted.

By leveraging the Gemini API, Lemonade ensures that whether you are launching a fintech disruptor or a community-driven nonprofit, your pitch is tailored, reviewed, and critique viewed to your specific mission.
