AI answers keep changing, sometimes dramatically, in a single day. $5/mo buys you more accurate answers, less noise, less wasted time & fewer mistakes to explain. Most importantly, we keep watching. When the models change their answer, we tell you, and hand you the receipts, so everyone knows AI got it wrong, not you. Being wrong is expensive.

- Warranty Manager: remembers what you own & what’s still covered

~95% Accuracy. i
95% is 59 right out of 62 hard reasoning questions we held back, nothing tuned for them. Claude Opus 5, the best AI we tested, got 59 right as well, on the 61 it returned an answer for. 62 questions is a small set, so read this as a first result we will keep re-running in public, not a settled score. Where we go further: we show you where the AIs disagree, so you know which answer to check, & you or an expert you hire can settle the one that matters to you.

What these
add i
The Notebook Auto-Organizer sorts 150 entries a month on Pro. Got a backlog? A bigger run clears it in 1 pass. 1-time charge, not a subscription.
- Included with Pro. 150 entries. Enough for a few months of notes as you go.
- $15. 500 entries. For a student or a working professional with a couple of years of notes, project files and saved links to pull together.
- $49. 2,000 entries. For a heavy researcher with years of material across many places: documents, transcripts, saved articles, whole projects. This is the one that clears a career's backlog in a single pass.
The Opus, o3, Fable & GPT-5.6 Sol boost is separate & it is monthly, & the number shown is always the TOTAL, not extra on top: for $4/mo more, Opus & o3 usage goes from 150 a month to 450 a month, & Fable & GPT-5.6 Sol from 10 a month to 20 a month each.
The Out-of-date answers boost works the same way: for $4/mo more, facts watched goes from 50 to 100, total.
