# AI Project Planner - Application Blueprint


## 1. Introduction


This document outlines the blueprint for the "AI Project Planner" web application. The primary goal of this application is to empower users, particularly those less experienced with AI platforms that utilize credit-based systems, by guiding them through effective project decomposition, assisting in crafting clear and efficient AI prompts, providing heuristic feedback on prompt complexity, integrating educational elements, and allowing for the extraction of text from documents for contextual use. This blueprint details the prioritized features, their specifications, and conceptual UI/UX flows.


## 2. Prioritized Features & Detailed Specifications


The features are categorized based on an initial prioritization (Must-Have, Should-Have, Could-Have) to guide phased development. Each feature includes User Stories, Functional Requirements (FRs), Non-Functional Requirements (NFRs), and, where applicable, Textual UI Flow and Element Specifications.


### Category: Core ("Must-Have") Features


#### Feature A1: Guided Project Goal Definition (Wizard-style)
*Description: A step-by-step wizard to help users articulate their main project goal, target AI platform (if known), and desired overall outcomes.*


##### 1. User Stories
* **US-GPGD-001 (Problem Articulation Focus):** As a novice AI user who is unsure how to start, I want to be prompted to describe the core problem I'm trying to solve or the opportunity I want to explore in my own words, before being asked about specific AI solutions, so that I can clarify my underlying need and ensure my project is focused on a real issue, rather than just exploring technology for its own sake.
* **US-GPGD-003 (Understanding AI Capabilities & Feasibility Focus):** As a novice AI user unsure of what the AI can realistically do, I want to receive simple explanations of relevant AI capabilities and limitations as I define my goal, and get an early indication if my broad goal type is well-suited to the platform, so that I can set realistic expectations and align my project with the AI's strengths, avoiding frustration later.
* **US-GPGD-004 (Cost/Credit Estimation Focus):** As a novice AI user concerned about unpredictable credit costs (especially on platforms like Manus AI), I want to receive a rough, heuristic-based estimation of potential credit consumption or complexity related to my defined project goal *during the goal definition phase*, so that I can make informed decisions about project scope and proceed with more confidence, reducing the fear of unexpected charges.
* **US-GPGD-005 (Actionable Output & Next Steps Focus):** As a novice AI user who has completed the goal definition wizard, I want to receive a clear summary of my defined project goal and have a tangible, actionable starting point for the next phase (e.g., task decomposition or first prompt), so that I feel a sense of accomplishment, understand what I've defined, and know how to proceed with my project within the planner.
