Simplicity
OneTab has one button. That's the entire UI. If you want the absolute simplest possible tool and never plan to use AI, OneTab's single-purpose design is genuinely hard to beat.
Sessionat vs OneTab
OneTab has two million users because it nails one thing: one click collapses every tab into a list. That’s still the whole product in 2026. Sessionat does the same thing — then adds auto-save, AI semantic search, chat, and cross-device sync on top.

The trade-off
The honest trade-off
OneTab is local-only by design. No cloud sync, no AI, no auto-save, no search beyond what Chrome’s Ctrl-F does on a plain list. The “no cloud sync” complaint is the single most-repeated feature request in their 14,400 reviews — and they've declined to add it for a decade.
In September 2025 they shipped a UI refresh that got immediate 1-star feedback (the rating dropped a few tenths and hasn't fully recovered). That's the story of OneTab in 2026: a tool from 2012 still doing 2012 things well, with users politely asking for the features Sessionat was built around from day one.
Sessionat matches OneTab's core promise — your tabs stay on your machine — then adds the AI layer OneTab won't build. If you love OneTab's simplicity, Sessionat's free tier is functionally identicalon the local side. You just gain the option to use AI when you want it.

Honest assessment
What OneTab still does better
Audience trust
Fourteen years of continuous operation, 2M+ users, and zero major trust incidents. Sessionat launched in 2024 — we're earning that track record, they already have it.
FAQ
Real questions we get about OneTab.
Can I import my OneTab list into Sessionat?
Yes. Export your OneTab list (right-click the icon → Export), then import the plain text or the JSON into Sessionat from Settings → Import. Each group becomes its own saved session.
Does OneTab send my tabs to a server?
No — OneTab is local-only. That's a feature (privacy) and a limitation (no sync). Sessionat matches the local-only default but adds opt-in AI that sends only the specific tabs you reference for one request.
What happens to my sessions if OneTab gets pulled from the Chrome Web Store?
They're stored in Chrome's local extension storage. If OneTab is removed, the storage stays but becomes harder to reach. Export your data regularly — same advice applies to every local-only extension including Sessionat.
Which one uses less memory?
Both are negligible when idle. OneTab is lighter on install (smaller extension). Sessionat runs a service worker that schedules auto-saves via chrome.alarms (MV3 minimum 1-minute interval), so has a slightly larger memory footprint when active — under 15 MB in practice.
Does Sessionat cost anything if I only want OneTab-style features?
No. The free tier covers unlimited local sessions, keyword search, export, and auto-save. You only pay if you want the AI features (Pro $19/mo for 5,000 credits).
