Text Blaze, a Y Combinator-backed productivity company with over 700,000 users and a 4.9/5 rating, is offering an unusual summer internship: candidates must agree to a complete ban on AI tools for the entire program. The "No AI Summer" internship targets late-college and early-career developers who want to train as full-stack engineers using JavaScript, Python, React, and GCP. The company explicitly believes industry over-reliance on AI has limited junior engineers' growth.

The startup argues that once developers move beyond simple tasks, AI dependence leads to poor quality work and wasted time. Despite the ban, Text Blaze uses AI extensively in its own products and acknowledges tools can deliver double-digit productivity gains for experienced engineers. This creates an intentional constraint: the company wants to train humans, not LLMs, to become excellent engineers who can think critically.

This approach directly challenges industry norms where AI coding assistants have become standard in most tech internships. Applicants submit a five-sentence cover letter describing a coding project, an achievement, and how they'd take advantage of the no-AI summer. The small team offers high impact potential for candidates ready to tackle hard challenges and develop real engineering skills.
