Midday peak
The line makes the heavier stretch of the day visible.
Cognitive load tracker for computer work.
TypeFuel runs passively on the computer you already use for demanding work. It learns your usual keyboard rhythm first, then shows when your cognitive load looks Low, Medium, or High against your own baseline.
See when today got heavier.
The dashboard shows the workday curve first, then the timing drivers that changed against your usual rhythm. If that experience sounds familiar, read why computer work can feel mentally heavier after work.
What changed
Correction rate and typing rhythm show what raised the estimate.
Compared with you
The view reads today against your own usual rhythm.
What is TypeFuel?
TypeFuel is a cognitive load app for people whose demanding work happens at a keyboard. It runs in the background, learns your work rhythm, and keeps the signal grounded in your own baseline.
No wearable
TypeFuel runs where the work already happens: on your computer.
No new gadget
There is no device to buy, pair, charge, remember, or wear.
No journaling
It learns passively while you work, then compares load with your own baseline.
How passive tracking works.
TypeFuel does not ask how you feel or make you log sessions. It learns keyboard timing patterns first, then compares later work rhythm with your usual baseline.
Install once
Grant the desktop permissions and keep working in your normal tools.
Build your baseline
TypeFuel learns keyboard timing, correction rate, typing rhythm, and typing speed.
Track your load
After confidence builds, the dashboard shows Low, Medium, or High cognitive load.
Your work content stays out of it.
TypeFuel tracks cognitive load from timing summaries, not the content of your work. Read The Deal for the full preview data boundary before installing.

The short version before you install.
Yes. TypeFuel is a cognitive load tracker for people who do demanding computer work. It runs passively on your computer and compares your work rhythm with your own baseline.
No. TypeFuel does not need a wearable, new gadget, extra battery, or manual journaling. It runs on the computer you already use for work.
Yes. Use Download to get the macOS or Windows Research Preview installer.
A desktop app that learns your normal work rhythm, shows baseline progress, and unlocks a Low, Medium, or High cognitive-load view after there is enough signal.
The visible Research Preview gauge uses keyboard timing summaries, including correction rate, typing rhythm, and typing speed. Mouse and cursor metrics are shadow research signals, not visible score drivers in v0.1. Read the methodology
Cognitive load is personal. TypeFuel first learns your usual rhythm so the later load view is compared with you, not with a generic population score. Read the methodology
No. TypeFuel stores timing aggregates, not typed words, passwords, app names, URLs, screenshots, files, screen text, or click targets. Read The Deal
No. TypeFuel does not classify apps, websites, projects, or billable time. It tracks cognitive load from timing rhythm and baseline changes. Compare TypeFuel with RescueTime
No. TypeFuel is built for personal cognitive-load awareness, not manager visibility, productivity scoring, surveillance, or employee monitoring.
No. TypeFuel is not a medical device, diagnosis, treatment, burnout detector, or clinical stress score. The Research Preview validates the signal conservatively. See the roadmap
