Stop re-teaching your AI every morning.

You didn't become a senior developer to spend 45 minutes re-explaining your stack. cachly gives your AI a permanent brain — it arrives pre-briefed, remembers every fix, and never makes the same mistake twice.

Your AI arrives knowing everything

cachly sends a full briefing at the start of every session. Your stack, your open bugs, what your team learned yesterday — all there before you type a word. No re-explaining. No repeated mistakes.

# cachly session briefing
 
▶ brain_recall({ topic: 'auth' })
 
→ JWT refresh race condition fixed
→ NEVER use RS256 in dev (cert overhead)
→ Auth service down Tuesdays 02:00 UTC
→ PR #847 merged: rate-limit middleware
 
✓ 4 memories recalled in 38ms

One command. Everything set up.

Run it once. cachly signs you in, detects every editor, writes all configs, and bootstraps your Brain from your entire git history.

1

Run the setup command

The wizard detects Claude Code, Cursor, GitHub Copilot, Windsurf, Cline, Zed — writes the correct MCP config for each. One browser click to sign in. No credentials in any config file. No OpenAI key required.

2

Your Brain bootstraps from git

cachly reads your entire git history and extracts lessons from every bug fix, revert, and architecture decision. Your AI knows your codebase the moment setup finishes — before you write a single line.

3

Your AI arrives pre-briefed — every session

Sessions start automatically on the first tool call. Every conversation begins with a briefing: what you were doing, what's open, what your team learned. Your AI never asks you to explain your stack again.

Four things no other tool does

Memory is the baseline. These are the superpowers.

causal_trace

30 minutes of git blame. One call.

Describe a problem in plain English. cachly walks your Causal Knowledge Graph — typed edges: fixes, requires, causes, contradicts — and returns the root cause, the failure chain, and the exact fix that worked. Including the date and the command.

▶ causal_trace({ file: 'auth.ts' })
 
Tracing 847 commits across 12 files...
 
Root cause: RS256 cert rotation every 24h
Introduced: PR #203 (3 months ago)
Affects: login, refresh, SSO flows
 
✓ 30 min of git blame in 1.2s
▶ brain_predict({ target: 'deploy' })
 
Analysing 234 past deployments...
 
HIGH RISK: Tuesday deploys fail 67%
→ DB migration timeout at step 4
→ Fix: run migration separately first
 
✓ Predicted before you typed git push
brain_predict

Know what breaks before you deploy.

Before every deploy, migration, or dependency upgrade, brain_predict scans your Brain for matching failure patterns and returns probability-weighted warnings. Catch your next incident before it happens.

learn_from_attempts

Every fix becomes permanent knowledge.

A git post-commit hook (installed by setup, automatically) sends every commit to your Brain. Every fix, revert, and deploy teaches cachly forever. Zero manual effort. You never call session_end. You never forget to save a lesson.

▶ learn_from_attempts({ since: '7d' })
 
Processing 43 commits, 12 reverts...
 
Learned: useEffect cleanup essential
Learned: Prisma batch > N+1 always
Learned: seed DB before Playwright
 
✓ 3 patterns auto-added to brain
▶ brain_recall({ q: 'auth fehler' })
 
Searching across 4 languages...
 
[EN] JWT refresh race condition fixed
[DE] RS256-Zertifikat: täglich rotiert
[AR] مشكلة المصادقة → OAuth2 PKCE
[JA] ログイン問題: レート制限で解決
 
✓ Cross-language hits in 41ms
brain_recall

Write in any language. Remember in every language.

cachly uses semantic embeddings, not keyword matching. A lesson stored in German surfaces when you search in English. A fix documented in Arabic matches a Japanese query about the same bug. Your team's knowledge has no language barrier.

Without cachly, you re-explain your stack for 45 minutes every day.

All four superpowers — causal_trace, brain_predict, and more — are included free, forever.

What developers say

causal_trace found the root cause of an auth bug we had been chasing for 3 days. One call. The exact fix from 3 months ago, with the command that worked.

Marcus K.
Senior Engineer, Berlin

I stopped explaining my architecture to Claude every morning. It just knows. After two weeks I genuinely cannot imagine working without it.

P
Priya S.
Staff Engineer, London

brain_predict warned us about a k8s namespace race condition before our deploy. Saved us a full incident. That alone paid for the subscription.

No. Sessions start and end automatically. The git hook learns from every commit automatically. You never call session_start, session_end, or save a lesson manually — unless you want to. cachly runs entirely in the background.
