Being new is hard. Unfamiliar codebase. Unwritten rules. Fear of asking "dumb" questions. diffray gives every new hire a team of patient specialists who teach your conventions, patterns, and best practices — in every PR.
New developers face the same challenges everywhere. It's not about skill — it's about context.
Thousands of files. Unfamiliar patterns. Where do you even start?
You don't want to interrupt seniors with 'basic' questions. Again.
Is this the right way? Or will someone rewrite it in code review?
Documentation is outdated. Slack history doesn't help. You're stuck.
Single-model AI tools try to teach everything and end up teaching nothing well. diffray deploys specialized agents — each an expert in their domain. It's like having 10 senior engineers reviewing every PR.
Secure coding practices
"This query is vulnerable to SQL injection. Here's how we handle user input safely in this codebase..."
Optimization patterns
"This creates an N+1 query problem. Look at how we solved this in OrderService using eager loading..."
Design patterns & structure
"We use the repository pattern here. Let me show you the existing implementation you can follow..."
Team conventions
"We use camelCase for variables and PascalCase for components. Here's the style guide in action..."
Edge cases & error handling
"What happens if the array is empty? Add a guard clause like we do in similar functions..."
Code documentation standards
"Public APIs need JSDoc comments. Here's the format we use across the codebase..."
Every new hire costs months of productivity — theirs and your senior engineers'
New hires take months to contribute independently. That's expensive waiting time.
Your best engineers spend hours answering questions instead of building.
Without knowledge transfer, new developers make the same errors as their predecessors.
Nobody wants to look inexperienced. With diffray, every PR becomes a private learning session. Feedback is educational, not judgmental. Questions are answered with patience, not sighs.
Feedback is educational, not critical. Every comment explains the 'why' with examples from your codebase.
Unlike humans, diffray never gets tired of explaining. Ask the same thing 100 times — same quality answer.
Suggestions reference your actual codebase. "See how we did this in UserService.ts" — not abstract theory.
diffray notices when you apply feedback correctly. Positive reinforcement helps patterns stick.
The best learning happens in context. Every PR is an opportunity to grow.
New developer submits their first pull request, nervous about the review
10+ agents analyze code — security, performance, architecture, conventions, and more
Each comment explains the issue, shows the correct pattern, and links to examples
Developer understands team standards and improves — knowledge compounds with each PR
"Our new engineers used to take 4+ months before contributing real features. With diffray teaching them our patterns in every PR, we're seeing meaningful contributions in 6-8 weeks."

"I was terrified of making mistakes in my first month. diffray doesn't judge — it teaches. I learned more from PR feedback than from any documentation."

Hired 3 months ago
"I used to spend 3 hours a day reviewing junior code and answering Slack questions. Now diffray handles the teaching, and I focus on architecture reviews and mentoring careers."

Documentation gets outdated. diffray teaches in context — when you're actually writing code. It references real examples from your codebase, not abstract best practices. Learning happens at the moment of doing.
No — it amplifies it. diffray handles the repetitive teaching (conventions, patterns, common mistakes) so your seniors can focus on high-value mentoring: career growth, architecture decisions, and complex problem-solving.
diffray learns from your codebase patterns and any custom rules you add via Playbook. It teaches what your team actually does, not generic best practices from the internet.
Team leads can add rules, correct the AI, and flag patterns to avoid. The system learns from your feedback. Unlike static docs, the teaching evolves with your codebase.
Yes, but that's the point — learning is normalized. When everyone sees educational feedback, asking questions becomes part of the culture, not a sign of weakness.
