Every day, you re-explain your codebase to an AI that forgets. cachly remembers it for you — fully automatically.

Run one setup command. After that, you do nothing: Claude Code, Cursor, Copilot & Windsurf arrive pre-briefed every session and learn from every commit — all in the background. Stop re-explaining. Stop repeating the same bugs.

Your AI walks in already knowing everything

cachly sends a full briefing at the start of every session — your stack, your open bugs, what your team learned yesterday. You never re-explain anything. You never repeat a mistake.

# 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
Zero effort · fully automatic

You don't do anything. That's the whole point.

No commands to remember, no lessons to save, no context to paste. After the one-time setup, cachly runs entirely in the background — your AI just arrives smarter every session.

🧠

Auto-briefed, every session

Each conversation starts with a full briefing on the first tool call — automatically. You never paste context again.

✍️

Auto-learns from every commit

A post-commit hook feeds every fix, revert and decision to your Brain. You never save a lesson or write a note.

🔮

Auto-warns before you break prod

Before risky deploys, cachly surfaces matching past failures on its own — no query, no prompt needed.

Set it up once. After that, doing nothing is doing it right.

The bill nobody talks about

You're paying to re-explain the same context every single session.

Every time your AI re-reads your stack, your files, and yesterday's decisions, you pay for those tokens again. Run agents at scale and that becomes five- and six-figure monthly API bills. cachly remembers instead of re-sending — and its semantic cache returns repeat answers for free. You ship more and pay less.

Cache hits = €0
every repeated answer served from the semantic cache is an LLM call you don't pay for
0 tokens
to re-explain your stack — your AI arrives already briefed
Never twice
you never pay to solve — or re-explain — the same problem again

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.

For you, your team, your whole org

When someone leaves, their knowledge usually walks out with them.

A wiki like Confluence only knows what people remember to write down — and almost nobody does. cachly is a living team brain that learns automatically from every commit, fix, and session. The lessons stay, even after the people don't.

🧠

Knowledge that compounds

One engineer's solved bug becomes the whole team's reflex — searchable in any language, surfaced before it bites again.

🚪

Zero knowledge loss when people go

When a teammate offboards, their hard-won lessons stay in the Brain instead of leaving in their head.

New hires productive in days

New devs — and their AI — arrive pre-briefed on years of architecture decisions from day one.

Start solo, share it with your team, or roll it out org-wide — the same Brain grows with you.

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.

Frequently asked questions

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.

Every session without cachly is context lost.

The average developer burns 45 minutes a day re-explaining their stack — that's €900/month in lost productivity, gone for good. One free command fixes it permanently.
