Scored by a Toolio reviewer after real useOur verdict
This small Chrome add-on gives ChatGPT a save-and-organize layer: keep favorite prompts, swap variables into them, and file everything under named projects instead of scrolling through old chats. It carries just two ratings and a tiny footprint under 125KB. What stands out most is candor from its own maker, who now recommends ChatGPT's native conversation presets and MyGPTs over reinstalling this add-on, since recent updates cover much the same ground.
✓What it does well

Reusable variablesVariables slot into saved prompts so one template covers many situations.
Project foldersPrompts sort into named projects rather than one long unsorted list.
✕Where it falls short
Maker recommends alternativesIts own developer now suggests ChatGPT's built-in Share presets and MyGPTs instead, since they no longer require a separate add-on.
Small user baseOnly two ratings are on record, so there isn't much outside evidence of long-term reliability.
One narrow jobIt does a single thing, storing prompt text, without chat, editing, or generation features built in.
