NVIDIA, Scale AI, and Brex trust Greptile for PR reviews that flag real issues, not just generic advice. Unlike tools that merely read code, TREX executes changes in a sandbox, returning screenshots and logs to prove what broke. This shift matters: 70% of AI-generated code requires verification, creating bottlenecks.

Greptile’s CLI runs locally before PRs, catching flaws early. The problem? LLMs lack native memory—each call starts fresh. Platforms simulate memory by appending context to prompts, but this hits limits.

A 40% cost increase occurs when context windows exceed 8k tokens, and latency balloons. The solution? Tiered memory systems, mirroring OS caching. Greptile’s integration with Claude Code ($0 for open source) shows how structured data-first architectures prevent slopocalypse.

Trusted by engineering teams, it bridges AI’s knowledge gaps with auditable, persistent memory.
