Built for code.
Not just text.

L2Cache doesn't just store strings. It understands code, extracts errors, and connects context. Scroll through to see each tool in action.

Decode JWTs & Format JSON

Click any raw JWT or minified JSON to instantly decode and format it on-device. No more pasting into random browser tabs.

OCR for Stack Traces

Someone sent a screenshot of an error? Copy it. L2Cache extracts the text instantly using Apple's Vision framework.

Terminal History

L2Cache detects terminal output and automatically extracts the root command (like docker, git, or npm) to tag your clips, making it easy to filter, find, and replay your past commands.

IA Agent Session History

Every Claude Code and Codex CLI session is captured in your clipboard history — prompts, responses, token usage, and cache hit rates. Review, search, and replay your IA coding sessions without leaving your workflow.

IA Data Generation

Select a SQL schema or Swift struct and run an IA prompt directly inside the clipboard to generate mock data instantly.

Programmable Appunti

View Recipes →

L2Cache lets you create custom actions in Bash or Ruby. Target actions dynamically based on content types like SQL, Docker, YAML, or GraphQL. Format, fetch, or filter copied text entirely on-device.

From Raw Data to Usable Code

Ordinary clipboards merely store raw data like unprocessed ore. L2Cache works as a miner, instantly refining that material into polished, ready‑to‑use gold.

Gli appunti
che hai sempre desiderato

Ogni copia salvata, compresa e pronta quando ne hai bisogno.

🧠
Titoli generati dall'IA
I frammenti di codice mostrano cosa fa il codice, non in che lingua è scritto. "Autentica utente e archivia sessione nel Portachiavi" — non "Funzione Swift".Richiede macOS 15.1+ e Apple Silicon. Sui Mac precedenti, utilizza titoli in testo normale.
⚡
Trasformazione intelligente
Copia in modo più intelligente. Trasforma i tuoi appunti mentre copi — rimuovi i blocchi markdown, correggi la grammatica, converti il codice, pulisci gli URL, formatta JSON.Le trasformazioni basate sull'IA richiedono macOS 15.1+ e Apple Silicon. Le trasformazioni istantanee locali funzionano su qualsiasi Mac supportato.
🍎
Apple Intelligenza
Viene eseguito sul dispositivo utilizzando il modello di fondazione di Apple. Privato per impostazione predefinita — i tuoi appunti non lasciano mai il tuo Mac.Apple Intelligenza richiede macOS 15.1+ e Apple Silicon. Le funzionalità principali degli appunti funzionano in ogni caso su macOS 13+.
📝
Screenshot OCR
Instantly extract and copy text from any screenshot or image using on-device optical character recognition.
🛠
SQL Mock Data Gen
Copy a SQL schema and let Apple Intelligenza instantly generate mock CSV or JSON test data directly on your clipboard.
🔍
Cerca tutto
Ricerca full-text su tutti i frammenti. Gli screenshot sono ricercabili in base al loro contenuto testuale tramite OCR. Trova qualsiasi cosa in meno di 100 ms.
🛡
Radar sensibile
Le chiavi API, i numeri di carta di credito, le chiavi private, i codici fiscali e le credenziali WiFi vengono rilevati automaticamente e memorizzati come nascosti. Il contenuto rimane bloccato — sbloccalo con il Touch ID o la password per copiarlo.
🔍
Regex pattern matching
Type standard Regular Expressions to filter your massive clipboard history natively. Instantly find AWS keys, IP addresses, or UUIDs using terminal grep-like syntax.
🗂
Album intelligenti
I frammenti vengono raggruppati automaticamente in album per tipo e contesto — codice, URL, immagini e altro ancora. Sfoglia gli album per trovare immediatamente frammenti correlati.
📱
Generazione di codici QR
Copia qualsiasi URL, testo o dettaglio di contatto e genera un codice QR con un solo clic. Condividi all'istante senza app aggiuntive.
🖼
Rinominazione degli screenshot
Gli screenshot vengono rinominati automaticamente tramite l'IA — non più "Screenshot 2025-06-18 at 10.34.02". Trova i tuoi screenshot in base al loro contenuto effettivo.
Wall of Love

Developers love L2Cache

Don't just take our word for it. Here is what engineers are saying.

★★★★★

"This is hands down the best clipboard manager for engineers. The ability to pipe my clipboard directly into a Ruby script without leaving my IDE is mind-blowing. It replaced Maccy for me."

S

Sarah J.

Senior Backend Engineer

★★★★★

"The Smart Actions are a game changer. Being able to extract a JWT payload or pretty-print JSON with a single shortcut saves me so much context switching every day."

M

Michael T.

Fullstack Developer

★★★★★

"Finally, a native macOS app that respects developers. It's incredibly fast, the SQLite search is instant, and the UI is absolutely gorgeous. Worth every penny."

D

David R.

iOS Engineer

FAQ

Common Questions

How much does L2Cache cost? +
L2Cache is a $4.99 one-time purchase with lifetime access. Pay once, own forever — all future updates are included with no recurring subscriptions.
Does L2Cache keep my clipboard history private? +
Yes. L2Cache stores your clipboard history locally on your Mac and its IA runs entirely on-device using Apple Intelligenza. No clipboard content is ever sent to any server.
What Macs does L2Cache work on? +
L2Cache runs on macOS 13 Ventura or later. Core clipboard history and search work on any supported Mac; the on-device IA features (smart titles, Trasformazione intelligente) require macOS 15.1+ on Apple Silicon.
How is L2Cache different from the built-in macOS clipboard? +
macOS only keeps the last copied item. L2Cache keeps unlimited history with full-text search, OCR search inside screenshots, smart albums, regex grep, JWT/JSON decoding, SQL data generation, custom scripts — and works back to macOS 13.
