y5s indexes your repositories and business requirements into one shared knowledge base — so every question, review, and decision is backed by your real code and your real rules.
of developers spend 30+ minutes a day just searching for answers
Stack Overflow Developer Survey, 2022lose 8+ hours a week to friction — insufficient docs a top cause
Atlassian State of Developer Experience, 2024The knowledge to fix all of this already exists — scattered across code, Slack, and a few people's heads. y5s puts it in one place your whole team can query.
Product, support, QA, a brand-new hire — anyone can ask y5s in plain language and get a real answer, grounded in the actual code and business rules. No interrupting an engineer. No waiting on a reply.
Link GitLab, GitHub, or Bitbucket with a read-only token. Add your requirements, ADRs, and process diagrams alongside the code.
y5s parses, embeds, and links everything into one knowledge base — in an ephemeral workspace that's destroyed the second it finishes. Webhooks re-index on every push, so it never goes stale.
Ask questions, generate diagrams, enrich knowledge, and get business-aware review on every merge request — from the web, your editor, or any MCP agent.
Most review tools ask "is this code clean?"
y5s asks "does this change break a business rule?"
When a merge request touches your payment logic, y5s pulls the relevant requirements, checks compliance, and posts a review comment before your reviewers even open the diff.
Not linting. Not style. Business-logic verification.
"How are refunds settled?"
Every question an AI coding agent answers by grepping and reading whole files drags thousands of lines into its context window — and you pay for every one of them, on every question, in every session.
Point Claude, Cursor, or any MCP agent at the y5s knowledge base instead. Retrieval runs on y5s — the agent asks one question and gets back a distilled, cited answer, not a pile of source files.
Smaller context. Lower usage bills. Answers grounded in your requirements and ADRs, not just the code the agent happened to open.
Ask in plain language, get an answer assembled from your real code and requirements — every claim linked back to the file it came from.
Each MR is checked against your documented business rules, with findings posted as review comments before a human opens the diff.
y5s is built on one principle: your code is never stored. It exists only as a short-lived process while we index it — then the workspace is destroyed. What remains is enough to answer questions, never enough to reconstruct your codebase.
"so where does our code actually live?"
— nowhere. that's the point.
