Problem — BUSINESS focus

Demonstrating profitability to investors is crucial for the early-stage startup, but

The product faces challenges in converting premium users

1.1 Business Problem

Problem — User Focus

Not everyone is an expert is making slideshows :(

User wants to spend as little in time, effort, and money to create better slides.

1.2 User Problem

Research — Summary

Low Productivity due to time wasted on aesthetic tweaks

To uncover areas for improvement, we conducted contextual inquiries and observational studies of users creating slides. We found that excessive time spent on minor aesthetic changes was a key contributor to unproductive slide creation.

3.1 User Flow Analysis

Research — Problem Statement

“How might we convert users to the premium version by saving them time in aesthetics and detail editing?”

DEsign Goals

User are more likely to pay for product that is

Intuitive to use

Designed to kept users' work at the center and prepare for rapid iteration without disrupting established patterns.

Empowering to use

Designed to empower users to interact with AI tools effectively, aiming to increasing quality and reducing time.

Rewarding to use

Designed to make users feel they've found the right tool, fostering customer loyalty, leading to increased conversions.

Success Metrics

Rapid AI (re)generation

Choosing the right form of visual communication media takes too much time and disrupts the user's workflow.

AI function that generates and modifies visual content based on the presentation context and user commands.

- Reduced Time Spent
- User Satisfaction Generated Content
- Workflow Continuity

AI Mass Edits

Repetitive edits are required when making changes across different pages wasting time and causes emotional distress

Mass editing AI that responds to textual commands to apply changes across multiple elements.

- Reduced Repetitive Edits
- Efficiency of Editing Commands
- User Satisfaction

Ideation — Feature Implementation

4.1 Feature Implementation

User Convenience — Crowded & OUtdated WorkSpace

User needs more horizontal screen real-estate for convenience

As 16:9 decks gain popularity, users are working with wider, shorter slides. Current interfaces, designed for the 4:3 format, feel unbalanced—featuring overly complex toolbars for everyday users and inefficient use of space on the sides and bottom.

5.1 Slide Dimension Changes

5.2 Layout Examination

User Convenience -- De-cluttered Interfaces

Clearing out the stage to let your work shines for convenience

To enhance slide focus and minimize clutter, we optimized for 16:9 by clearing horizontal space. Non-editing commands were moved to the top, while the dense, frequently used editing toolbar was shifted to the bottom. This streamlined layout prioritizes key tools and improves user workflow.

User Convenience — Designed for scaleability

Designing for future scalability without disrupting user habits

To minimize bottom toolbar content, we moved editing actions to a dynamic toolkit that appears with element selection, cleaning up the interface while maintaining ease of use. This approach also supports scalability, allowing the toolbar to adapt as new features are added.

“This tool is convenient and useful, but the AI output is not ideal"

User Autonomy — Back to research

Users seem to believe AI is magic that fixes everything

Ideal Scenario — Rapid iteration with generative AI

6.1 Ideal User Flow

6.2 Ideal User-AI Interaction

Unfortunately, generative AI makes mistakes all the time

Reality — Repeated re-generation loop

This leads to...

User Frustration

Users became extremely upset when unable to generate content, given their high expectations. This quickly led to a loss of trust in the product.

Long Generation Time

Visual content took significantly longer to generate compared to text content. Users were unwilling to wait more than 1-2 seconds, leading to dissatisfaction.

Loss for Business

Each content generation incurs a cost for the business. In our subscription-based model, repeated generation attempts become extremely costly.

User Autonomy — Enhanced Control Via Additional Input

User needs more control over the generated content

Adding one extra step in generation workflow

6.5 Improved User Autonomy Demo

Improve Satisfaction

With refined instructions, AI is able to better understands user needs, resulting in higher satisfaction with the generated content within the first three tries.

Willingness to Wait

Despite users spending more time they receiving better results. The perceived wait time also appear to be shorter for them, and willing to wait longer.

Decrease Operating Cost

Increased user satisfaction has led to fewer generation attempts avoiding the regeneration loop . This decreased operating costs in by over 50%.

User Autonomy — Balance Control and Automation

Users needs suggested choices to make fast decisions

6.5 Smart Choices Demo

Balancing user autonomy and AI automation with AI suggestions

Testing revealed that task speed improves when AI provides snippets, especially for visuals, while users prefer final control. In the mass editing agent, users give text commands, and AI suggests 2-4 options with hover previews. This enhances autonomy, speeds tasks, and reduces repetitive AI use for better outcomes.

“ I felt I saved time on making slides, but it just doesn't look as nice as I wanted to. I don't know where it went wrong!"

User Empowerment — back to research

User tries their best, but still creates mediocre slides.

- User Confidence in Visual Presentation
- Reduced Time Spent on Polishing

Let an expert AI assist in reviewing your slides

7.1 New Feature Implementation

User Empowerment — Solutions

Smart review, and smarter edits

7.2 AI Review Agent Demo

Closing Knowledge Gaps

AI agent offers personalized suggestions and , helping users improve slide design beyond their current knowledge to improve overall productivity.

Accelerating Workflow

AI agent provides targeted feedback which reduces the need for trial and error, significantly cutting down the time spent on slide adjustments.

Enhanced Confidence

User often felt more confident about their slides post usage, leading to more informed decisions, reduced hesitation, and overall improvement to fqulaity

User Empowerment — Rewarding to Use

Rewarding product leads to returning subscribers

Engaging user for longterm conversion

In a competitive market, attracting users is just the start—retention is key. To convert first-time users into loyal subscribers, the product must be engaging and rewarding. In the mass editing agent design, users input text commands while AI suggests 2-4 modification options with hover previews. This enhances user autonomy, speeds up tasks, and reduces repetitive AI usage, leading to a more satisfying experience that encourages users to return.

Retrospectives

Embracing Chaos in the Design Process

While I started with the Double Diamond and Design Thinking frameworks, I quickly realized that real-world design processes are often more chaotic. Research, ideation, and prototyping happen throughout the project, not just at the beginning. Being flexible and adaptive is crucial to avoiding wasted resources and staying effective in a constantly changing environment.

Design’s Impact Is Greater Than I Imagined

When I first entered the industry, I underestimated how much design could influence a project. Faced with challenges like slow and sometimes inaccurate AI model generation, I discovered that design could improve user interaction and satisfaction, even in areas traditionally seen as engineering problems. This experience taught me to always seek creative ways to tackle seemingly insurmountable issues.

User Testing & Behavioral Observation : Unlocking Better Insights

Working under tight timelines often meant relying on guesswork, making user testing essential. Observing both verbal feedback and subtle behavioral cues—like users triple-clicking out of frustration—revealed critical insights into the emotional journey of users. These observations helped me design experiences that truly resonate with users on a deeper level.
