No credit card required · First booking free

SubSideKick alerts you when a job is posted. RoboSub books it before anyone else can.

An alert is only useful if you see it in time and act faster than every other substitute watching the same board. Nemo removes the race entirely.

The Real Difference

What happens when a job is posted

RoboSub

Nemo detects the job the moment it appears on Frontline, checks it against your school preferences and schedule, and books it automatically — all within seconds. You receive an email confirmation. The job is yours.

SubSideKick

SubSideKick sends you a push notification. You see it, unlock your phone, open Frontline, find the job listing, and tap to book. If another substitute received the same alert and had their phone in hand, the job may already be gone.

Pricing model

RoboSub

$1 per successfully booked job. First booking is free. No monthly fees, no subscription, no charge if Nemo doesn't book anything. Your cost is directly proportional to your earnings.

SubSideKick

SubSideKick charges a recurring subscription regardless of how many jobs you receive or miss. You pay the same amount whether Nemo books you 20 jobs or zero.

Control and transparency

RoboSub

Every scan, job match, and booking attempt is logged in your activity feed. You can see exactly what Nemo is doing in real time, set your preferred schools, block individual dates, and pause Nemo at any time.

SubSideKick

SubSideKick surfaces job alerts. The booking action, timing, and outcome are entirely up to you — there's no audit trail of what you missed or why.

Common Questions

What is the difference between RoboSub and SubSideKick?+
SubSideKick sends you a notification when a Frontline substitute job is posted, but you still have to manually open Frontline and book the job yourself. RoboSub goes further: Nemo, our automated booking engine, books the job the moment it appears — no manual action required. By the time a SubSideKick alert reaches you, a RoboSub user may already have the job confirmed.
Is RoboSub cheaper than SubSideKick?+
RoboSub charges $1 per successfully booked job with no monthly subscription. Your first booking is completely free. You only pay when Nemo actually books a job for you — nothing if nothing gets booked.
Can I switch from SubSideKick to RoboSub?+
Yes. Sign up at robosub.ai, connect your existing Frontline account in Settings, configure your school preferences and availability, and start Nemo. No changes needed in Frontline — RoboSub works alongside your existing account.
What if I still want notifications?+
RoboSub emails you every time Nemo successfully books a job. You get the notification you're used to — plus the job is already confirmed before the email lands.
