3.2 Genspark's Cautions
On the other hand, AI hallucinations and context management issues require attention. For long work sessions, it is important to regularly transition chat screens and to save critical information externally.
Practical Use Case
As a common case, Genspark is the first choice for development involving Web API integration and research into the latest technology trends. Its real-time search function enables development always based on the most up-to-date information.
4. ChatGPT's Features and Strengths
ChatGPT's greatest feature is its balanced versatility. As a conversational AI developed by OpenAI, it offers stability and a proven track record suitable for a wide range of applications.
4.1 ChatGPT's Main Strengths
- Code generation capability: High-quality code generation supporting various programming languages
- Long-term memory function: Remembers user's past conversations and maintains context
- Plugin ecosystem: Rich external integration plugins
- Stable performance: Continuous improvements driven by a large user base
When ChatGPT is Optimal
- General coding tasks
- Maintaining context in long-term projects
- Code generation in various languages
- Document creation and text proofreading
4.2 ChatGPT's Cautions
ChatGPT has a weakness regarding information after its training data cutoff date. When the latest technology or current affairs information is needed, it is effective to utilize plugins or switch to Genspark.
Practical Use Case
As a common case, ChatGPT is frequently used for creating Python scripts and refactoring existing code. Especially in production environments where code quality is crucial, ChatGPT's stability is leveraged.
5. Claude's Features and Strengths
Claude is an AI tool excellent in logical reasoning and large-scale context processing. Developed by Anthropic, it demonstrates high performance particularly in complex problem-solving and long-text comprehension.
5.1 Claude's Main Strengths
- Large context: Ability to process vast contexts at once
- Logical reasoning: Decomposes and solves complex problems step by step
- Accuracy-focused: Provides careful and reliable responses
- Natural Japanese: Very natural and easy-to-read Japanese expressions
When Claude is Optimal
- Development requiring complex algorithm design or logical reasoning
- Analysis of large volumes of documents or code
- High-precision text proofreading and translation tasks
- Academic research and report writing
5.2 Claude's Cautions
Claude has limited external tool integration and does not support real-time information retrieval. Also, its response speed is somewhat slow, which might make it unsuitable for rapid prototyping.
Practical Use Case
As a common case, Claude is used for designing complex business logic and analyzing large log files. Its logical and step-by-step explanations make complex problems easier to understand.
6. Practical Usage Strategies
To effectively use the three tools strategically, a strategy based on development phase and task nature is crucial. Below, we introduce practical ways to use them.
6.1 Strategic Use by Development Phase
| Development Phase | Recommended Tool | Reason |
|---|---|---|
| Requirements Definition / Research | Genspark | Optimal for latest information retrieval and research |
| Design / Architecture | Claude | Strengths in logical reasoning and large-scale context processing |
| Implementation / Coding | ChatGPT | Balanced code generation capability |
| Prototyping | Genspark | Enables rapid development in an integrated environment |
| Testing / Debugging | Claude + ChatGPT | Combination of logical analysis and code correction |
| Document Creation | Claude | High-quality text generation and proofreading |
6.2 Strategic Use by Task Nature
- Research on latest technologies → Genspark (real-time search)
- Standard implementation → ChatGPT (stable code generation)
- Complex logic → Claude (logical reasoning)
- Large data analysis → Claude (large context)
- API integration development → Genspark (integrated environment)
Benefits of Using Multiple Tools Together
By appropriately using three tools in a single project, development efficiency can be significantly improved. For example, a workflow where Claude is used for design solidification, ChatGPT for implementation, and Genspark for incorporating the latest information is effective.
