Senior Level Coding
Because most AI coding tools only read part of each file, they miss critical code — the kind that would completely change the right approach, or that causes bugs later because it was never accounted for. Then you're stuck running pass after pass, fixing problems it caused by never reading the file in full. We decided to eliminate this problem entirely.
What's actually different
52.4M context
Large enough to read every file in full to ensure not a single piece of code is missed — most tools only see whichever file happens to be open at the time.
History that follows you
Your conversations are encrypted and synced across every paired device, so you can pick a session back up where you left it.
Nothing ships without your review
45% of developers say fixing AI-written code takes longer than writing it themselves. Every change Quantum makes is shown to you before it's applied, so problems get caught before they cost you time.
