Question 1

What is the best AI tool for developers in 2026?

Accepted Answer

Cursor is the best AI coding environment for professional developers — its Composer agent, full repo indexing, and multi-file editing are class-leading. For AI assistance alongside your existing IDE, Claude is the strongest model for complex reasoning, code review, and system design. GitHub Copilot is worth considering for teams deeply integrated into the GitHub workflow needing PR summaries and code review within that ecosystem.

Question 2

Which AI tool has the best API for building with?

Accepted Answer

Anthropic's Claude API and OpenAI's API are the two strongest options. Claude's API is preferred for complex reasoning and large context needs (200k tokens), while OpenAI's API has the largest ecosystem, most integrations, and multimodal support. Both offer generous free credits for new developers. DeepSeek's API is an excellent low-cost option for open-weights workloads.

Question 3

Is GitHub Copilot worth paying for?

Accepted Answer

For individual developers, it's hard to justify at $10/mo when Codeium offers comparable autocomplete for free. For teams heavily embedded in GitHub — needing PR summaries, AI code review, and enterprise SSO — Copilot's native GitHub integration makes it worthwhile. Cursor is typically the better upgrade path for individual developers who want maximum productivity.

Question 4

What AI tools do senior engineers actually use?

Accepted Answer

Senior engineers tend to use Cursor for their coding environment, Claude for architecture discussions and complex problem-solving, and custom LLM setups via the Anthropic or OpenAI API for domain-specific tooling. Warp is popular as an AI-first terminal. Many also use Perplexity for quick technical lookups where real-time, cited answers matter more than training-data recall.
