an AI assistant for echo360.

open a lecture and ask it anything. it knows what was said.

backbencher open inside an echo360 lecture page
backbencher explaining a lecture concept
ask it anythingit sat through the whole lecture, so it explains any concept in plain english — a clear, structured answer instead of a wall of transcript to scroll through.
backbencher drawing a diagram from the lecture
get a diagramask it to draw something out and it builds a diagram from the lecture content — handy for the stuff that only clicks once you can see how the pieces connect.
backbencher highlighting exam-relevant content
find what's on the examask what actually matters and it pulls out whatever the lecturer flagged as important — so you revise the right things, not all 90 minutes.

hey. i'm nav.

i built this because i was tired of rewatching lectures to find the one thing i missed. echo360's interface doesn't help. the transcript is there, but you can't search it, reference it, or do anything useful with it. and asking a chatbot "what did the prof say about dynamic programming at 40 minutes" when it hasn't seen the lecture is completely useless.

so i built backbencher for myself. sent it to my group chat. now a few hundred students use it. i'm currently studying at La Trobe.

the mascot is kind of me. the student who shows up, sits in the back, and somehow still needs to pass the exam. the name's backbencher because that's who this is for. not just the front-row note-takers, though they use it too (apparently).

this runs on real servers and real AI credits. i try to keep it as affordable as possible because i want it accessible to the students who need it most. if you've found value in it and want to help keep the lights on, here's how:

40 free lectures a month while exams are on, 10 after. resets the 1st. or top up for the price of a Red Bull.

$4AUD
20 credits
about a can of Red Bull
red bull pack
$8AUD
50 credits
about a latte (my fav)
coffee pack
$15AUD
80 credits
about a cocktail

whatever you decide, thanks for using it. i hope it helps.

also: i would genuinely love to hear from you. this is not a corporation. just a dude trying to build something useful between assignments. if something's broken, if you have an idea, or you just want to say hi, please reach out. it really does mean a lot. get in touch here.
