Tell Sieve what you're building. It reads every tab against that goal — silently, locally, instantly. What doesn't serve the work gets blocked.
No cloud · No account · No blocklist · Just your goal
How it works
One sentence in plain English. "Fixing the payment bug." "Reading about ML." Whatever the work actually is.
Open tabs the way you always have. Sieve runs in the background without changing how you work.
A local AI reads the content of every tab against your goal. No URL lists. No categories. Actual judgment.
Off-goal pages are soft-blocked with a reason. You can always override — Sieve advises, you decide.
Current goal
Calibrate Sieve to match how the day actually feels.
Sieve steps back. Browse freely until you're ready to focus.
Lenient. Good for research where you need to follow threads.
Blocks pages that don't serve the goal. You can always override.
Strict. Fails closed. A 5-minute break-glass is always available.
