What I Built
I developed **Electra AI Recon (Hardware Vector Search)**, an AI-powered gadget recommendation engine that helps users find perfect electronic devices based on their exact technical requirements. The app uses Google AI Studio's Gemini API to perform semantic "vector-style" searches, analyzing specifications like RAM, storage, processor, and budget to deliver personalized hardware recommendations with detailed technical analysis.
Key prompts & features used:
- `Act as an expert hardware architect. Perform a semantic "vector-style" deep search...` - Main analysis prompt
- Google Search grounding for real-time market data
- Structured JSON responses with defined schemas
- Follow-up conversational interface for technical discussions
- Comprehensive technical warnings and longevity projections

## My Experience
### What I Learned
Building this application with Google AI Studio was an enlightening experience that revealed several powerful capabilities:
1. **Structured Outputs are Game-Changing**: The ability to define exact JSON response schemas using the `responseSchema` parameter eliminated hours of parsing and validation work. Gemini consistently returns perfectly structured data that integrates seamlessly with TypeScript interfaces.
2. **Grounding with Google Search Adds Credibility**: The `googleSearch: {}` tool integration provides real-time market data, ensuring recommendations aren't based on outdated information. Seeing actual product sources cited in responses builds user trust.
3. **System Instructions Create Specialized Personalities**: By setting clear system instructions (`"You are a high-end hardware consultant"`), I created an assistant that maintains technical expertise throughout conversations, avoiding generic responses.
4. **Context Management is Key**: The stateless chat pattern with explicit context passing showed me how to maintain coherent conversations about specific hardware recommendations across multiple interactions.
### Surprising Discoveries
1. **The "Vector-Style" Metaphor Works Surprisingly Well**: Though not actually using vector embeddings, framing the search as a "semantic vector-style deep search" prompted Gemini to consider multidimensional fitness across all specifications simultaneously, resulting in more balanced recommendations.
2. **Technical Warnings Were More Insightful Than Expected**: Gemini generated specific, actionable warnings like "thermal throttling in sustained workloads," "soldered RAM limits future upgrades," and "proprietary charging ports reduce travel convenience" - exactly the kind of expert insights I wanted.
3. **Price Sensitivity Understanding**: The model demonstrated nuanced understanding of budget constraints, sometimes suggesting slightly older models with better build quality over newer, cheaper alternatives with compromises.
4. **Long-Term Projection Accuracy**: The longevity assessments considered factors like software support cycles, repairability scores, and industry trend alignment that I hadn't explicitly requested.
### Challenges and Solutions
**Challenge**: Maintaining conversation context about specific products
**Solution**: Passing the full analysis result as system instruction context, along with conversation history mapping between UI roles ('assistant') and Gemini roles ('model')
**Challenge**: Getting consistent match scoring
**Solution**: Explicit scoring instructions in the prompt plus schema enforcement ensuring numeric scores between 0-100
**Challenge**: Balancing technical depth with accessibility
**Solution**: Two-tiered output - immediate recommendations with key specs, plus expandable comprehensive technical analysis
### The Power of Google AI Studio
What stood out most was how **production-ready** the tools felt. The combination of:
- Reliable structured outputs
- Built-in web search grounding
- Clear documentation
- Responsive models (gemini-3-flash-preview was impressively fast)
...made this feel less like experimental AI tinkering and more like building with established engineering tools. The TypeScript SDK integration was particularly smooth, with excellent type hints and error messages.
### Final Thoughts
This project convinced me that AI-powered specialized recommendation engines represent a massive opportunity. Hardware purchasing is confusing even for technical users - having an expert-level assistant that considers all specifications, market context, and long-term value changes the game.
Google AI Studio provided the perfect balance of power and structure. The constraints (like requiring schemas) actually helped build a more reliable application, while the flexibility (through prompting and system instructions) allowed creating a truly domain-specific expert.
