The problem
You've been there.
Browser crash
47 tabs. Browser updates. System restart. Everything gone. Hours of context — vanished.
4 GB RAM, 3 windows
You know you should close tabs. But closing means losing context. So you don't.
No project switching
Work, side project, research, shopping — all mixed in one chaotic tab bar.
The transformation
Chaos → clarity, as you scroll.
Every tab below is a real context you're juggling right now. Watch them organize themselves into SeshTab as you scroll.

FAQ
Honest answers.
Will SeshTab slow down my browser?
No. The background script sleeps when inactive. It uses a fraction of Workona's memory — we benchmark publicly.
Is my data safe in the cloud?
The Free tier is 100% local — nothing leaves your device. Pro uses Supabase with Row Level Security and encryption in transit.
OneTab is free. Why pay for Pro?
OneTab has no cloud sync and has caused data loss after browser updates. Pro backs up your sessions in real time.
I've installed 5 tab managers and abandoned them all.
SeshTab shows you value before asking for an account. Install, save your first workspace in 60 seconds, then decide.
Is AI really useful here or just marketing?
It groups your tabs by topic on demand. You can ignore the feature entirely and SeshTab is still worth it.
