About this tool
Log every AI task, the model used and whether the answer shipped or had to be redone, then see first-pass rate and time saved.
AI Usage Journal is a running log of the tasks you hand to an AI assistant, scored so you can see how often the output ships untouched and how much time it really saves. Each entry records the task, the model, the number of re-prompts and one of five outcomes — used as-is, light edit, heavy rewrite, redone from scratch, abandoned — which are weighted 1.0, 0.75, 0.4, 0.15 and 0 to produce an effectiveness score out of 100. Useful for anyone who has to justify an AI subscription, choose between assistants, or find the task types where the tool is quietly costing more time than it saves.

A heavy rewrite counts as 0.4 of a completed task, not a success, so the score reflects real rework.
Time saved is reported after subtracting the minutes you spent prompting and re-prompting.

There is no published benchmark, which is exactly why logging your own baseline matters. In this journal a task counts toward the first-pass rate only when it was used as-is on the first attempt, so a rate of 40-60% on well-scoped tasks is already a strong result, while long-form or highly specific work usually lands much lower.
Estimate how long the task would have taken you from a blank page, then record that figure. The journal subtracts the minutes you spent prompting, so an entry with 45 minutes saved and 15 minutes spent nets 30 minutes — if you cannot honestly say the unaided version would have taken longer, record zero.
It is the average outcome weight across all entries, multiplied by 100. Used as-is scores 1.0, light edit 0.75, heavy rewrite 0.4, redone from scratch 0.15 and abandoned 0, so three tasks scored 1.0, 0.75 and 0.15 give an average of 0.633 and a score of 63.3 out of 100.
