The Code Review Tool Built by
Developers Who Were Tired of Waiting
We've all been there: It's 5 PM on Friday. You've just opened a critical pull request that needs to ship. And now you wait.
6 hours. 12 hours. Sometimes until Monday.
The $85 Billion Problem
In 2024, engineering teams spend an average of 10+ hours per week per developer waiting for code reviews. Not writing code. Not fixing bugs. Just... waiting.
The traditional code review process is broken. Senior engineers are overwhelmed. Junior developers are blocked. And every PR that sits idle is money burning while your competitors ship.
We tried the existing AI tools. They were fast, sure. But they were also shallow. They'd catch basic syntax issues but miss the architectural problems that cause real outages. They'd spam PRs with false positives while ignoring critical security vulnerabilities.
Why? Because they treat code as text, not as the living, breathing architecture it actually is.
How We Built It Different
We started with a simple question: "What if AI could review code the way a senior engineer does?"
Senior engineers don't just read code line by line. They understand architecture. They see how a change in one file ripples across the entire system. They know which "small" changes hide massive technical debt.
So we built Mesrai with three layers that mirror how expert engineers think:
AST Parsing
Parse code into Abstract Syntax Trees to understand structure, not just text. We see your code the way compilers do—as a graph of relationships and dependencies.
Semantic Chunking
Intelligently segment code while preserving context. Changes don't happen in isolation—we analyze their impact across your entire architecture.
Multi-Agent AI
7 specialized AI agents (Security, Performance, Architecture, etc.) review in parallel—each with deep expertise in their domain, cross-verifying findings to eliminate false positives.
The result? Code reviews that catch what other tools miss, delivered in ~2 minutes instead of 23 hours.

Why Deep Analysis Matters
⚠️The Problem With Surface-Level Tools
Traditional AI code review tools treat your codebase as a pile of text files:
- ×Miss architectural issues that require understanding relationships between files
- ×Can't detect circular dependencies or breaking changes
- ×Generate 10-20 comments per PR, most being false positives
- ×Require manual configuration for each codebase
✓The Mesrai Difference
With AST parsing and semantic chunking, Mesrai understands your code structurally:
- ✓Traces how changes propagate through your entire architecture
- ✓Detects subtle breaking changes and security vulnerabilities
- ✓Provides 2-5 high-value comments that actually matter
- ✓Learns your team's patterns automatically
Built on These Principles
Your Code Stays Private
Zero data retention. Your code is analyzed in real-time and never stored. Complete privacy and security guaranteed.
Speed Without Compromise
~2 minute reviews don't mean shallow analysis. Our parallel multi-agent system delivers both speed and depth.
Signal Over Noise
We filter out false positives through cross-agent verification. Only actionable, high-confidence issues reach your PRs.
Free to Get Started
Start reviewing code immediately with our free tier. No credit card required, no hidden costs—just better code reviews.
Our Mission
To eliminate the wait for code reviews and give every developer access to senior-level feedback— instantly, accurately, and at scale.
We believe great code shouldn't wait. Ships shouldn't be delayed because reviewers are in different timezones. And architectural insights shouldn't be bottlenecked by senior engineer availability.
Frequently Asked Questions
Everything you need to know about Mesrai's AI-powered code reviews
Mesrai uses AST (Abstract Syntax Tree) parsing and semantic chunking to understand your code's structure, not just treat it as text. This means we can detect architectural issues, trace dependencies across files, and provide insights that require deep codebase understanding—the kind of problems only senior engineers typically catch.
Mesrai completes comprehensive code reviews in approximately 2 minutes on average. Our multi-agent system analyzes your code in parallel, delivering senior-level feedback without the 23+ hour wait times typical of manual reviews.
AST parsing converts your code into a syntax tree that represents its structure. This allows Mesrai to understand relationships between functions, classes, and modules—not just individual lines. We can detect issues like circular dependencies, architectural violations, and context-dependent bugs that text-based tools miss.
Yes. Your code is analyzed in real-time and never stored on our servers. We use zero data retention—your code passes through for analysis and is immediately discarded. All processing happens securely, and you maintain complete control over your data and compliance requirements.
Mesrai supports all major programming languages including JavaScript/TypeScript, Python, Java, Go, Rust, C++, and more. Our AST parsing adapts to each language's syntax to provide accurate structural analysis regardless of the language you're using.
Mesrai offers a free tier to get started with no credit card required. Paid plans are available for teams and enterprises with additional features and higher usage limits. Contact us for custom enterprise pricing and volume discounts.
Yes! Mesrai integrates seamlessly with GitHub and Bitbucket. You can set up automatic code reviews on pull requests, customize review rules, and get insights directly in your workflow. Our API also supports custom integrations for advanced use cases.
Mesrai achieves 94% accuracy through our multi-agent verification system. Seven specialized AI agents (Security, Performance, Architecture, etc.) analyze your code in parallel and cross-verify findings to eliminate false positives, ensuring you only receive actionable, high-confidence feedback.
