Announcing RepoMemo RAG|Interactive Codebase Demo

Your codebase has 50,000 lines.
RepoMemo knows every single one.

Stop losing hours to blind grep, stale documentation, or endless context-switching. RepoMemo parses your AST, vectorizes your entire Git tree into pgvector, and gives you precise architectural answers backed by verified file citations.

The Developer Reality

Why is reading code 10x harder than writing it?

Modern software engineering isn't limited by your ability to write loops or functions. It is choked by the lost days spent deciphering 100,000 lines of legacy architecture.

The Exhausting Status Quo

Blind searches, broken assumptions, and wasted sprint cycles

Blind Grep & 400 False Positives

You search for an action name and get buried under lockfiles, mock tests, and type declarations with zero clues about the runtime execution flow.

The Senior Engineer Tax

You hesitate to open a PR because you don't know what hidden side effects might explode. You interrupt senior engineers on Slack, derailing their focus.

Stale Wikis & Dead Docs

The README says to configure a Redis queue that was replaced 6 months ago. The architecture docs were never updated, leaving you to reverse-engineer Git blame.

The RepoMemo Reality

Living, photographic memory grounded in your exact repository

Semantic Graph & AST-Aware Search

RepoMemo understands that UserButton.tsx connects to auth.ts and Prisma session records—even if they share no exact keywords.

Autonomous Onboarding in Minutes

New hires ship their first production pull request on Day 2 instead of Week 3. Ask architectural questions in natural language and receive step-by-step traces.

Always Synchronized to Commit SHA

Never trust stale documentation again. RepoMemo anchors answers to the active Git commit SHA and points you directly to line numbers in source files.

Active Demo Target
Next.js + pgvector

Indexed repository: ishanjarwal/repomemo (145 files, commit sha 94f1c8d)

How does authentication session refresh and client hydration work?
Grounded with pgvector semantic similarity & code AST
Synthesized in 240ms

Better-Auth hydrates initial server sessions into React state and synchronizes with cookies across SSR and client navigation.

Detailed Execution & Flow Trace

  • 1Root layout receives the session server-side via `auth.api.getSession` and passes it through to providers.
  • 2The client-side `UserButton` hydrates session state using `auth.hydrateSession(initialSession)` to prevent layout shift or hydration mismatch.
  • 3Session tokens are indexed in PostgreSQL under the `Session` model with cascade deletion on user removal.

How RepoMemo constructs living repository memory

A resilient, deterministic RAG architecture engineered specifically for source code trees, dependencies, and cross-file relationships.

01GitHub API & Inngest

Tree Ingestion & Commit Anchoring

Point to any public repository or connect a private repo with an AES-encrypted Personal Access Token. RepoMemo fetches the file tree at the active commit SHA, automatically discarding build noise, lockfiles, and binary assets.

•Commit-anchored indexing prevents stale cache
•Encrypted PAT handling in compliance with zero-leak protocols
•Intelligent AST filtering for code, schemas, and configs
02Google GenAI + pgvector

768-Dim pgvector Semantic Graph

Files are summarized and vectorized into 768-dimensional dense embeddings. Stored directly within PostgreSQL using the pgvector extension, creating an architectural spatial graph of your entire codebase.

•Semantic similarity matches intent, not just raw keywords
•Sub-second vector retrieval over thousands of code files
•Relationship modeling across caller and callee modules
03Zero Hallucination RAG

Grounded Synthesis & File Citations

When you ask a question, RepoMemo retrieves the most relevant multi-file code fragments, synthesizes the execution flow, and presents answers complete with exact file paths, line ranges, and follow-up prompts.

•Every claim is linked to source code line numbers
•Generates suggested follow-up queries automatically
•Persists answers to project history for team reference
Tailored Engineering Workflows

Built for developers who value their engineering velocity

Whether you're ramping up on day one, auditing critical PRs, or navigating open source giants, RepoMemo removes the cognitive friction of reading complex code.

The New Hire on Day One

Ship a production PR in Week 1, not Month 2

You just joined an engineering team with a 70,000-line monolithic codebase. No documentation, half the team is in a different timezone, and you need to build your first feature.

Sample Query:

"Where in the application is the Stripe customer portal session generated and what middleware protects it?"

Result: Autonomous onboarding without feeling like a burden to senior mentors.

The Tech Lead & Code Reviewer

Audit PR blast radius before hitting merge

A contributor opened a PR refactoring database schema or updating authentication cookies. You need to know which auxiliary background jobs or webhooks might fail.

Sample Query:

"What background Inngest functions or tRPC routers read the ProjectJob status field?"

Result: Spot regressions and race conditions before code ever reaches staging.

The Open-Source Explorer

Navigate massive 50k-star libraries with ease

You want to fix a bug or add an integration to Next.js, LangChain, or Prisma, but the codebase size is utterly intimidating.

Sample Query:

"How does the custom provider interface register new LLM backends?"

Result: Find the exact entrypoint and file interfaces in seconds without maintainer hand-holding.

The Contractor & Agency Builder

Audit legacy client codebases on a tight deadline

You inherit an undocumented startup repository that three different dev agencies touched over four years. Client expects a feature roadmap in 48 hours.

Sample Query:

"List all external third-party API integrations, secret keys required, and database relationships."

Result: Deliver an architectural audit report on Day 1 that blows clients away.
