Learn anything. Actually remember it.

You read the whole thing and remember none of it. Axo turns any topic, or any document you paste in, into a short course with a finish line, built on the science of how memory actually works.

A chatbot hands you a wall of text. You skim it, nod, and lose it by Friday. Axo gives you the same knowledge as a Path: four units, sixteen Bites, questions instead of summaries, and a review that comes back right before you would forget.

Attention isn’t broken. It’s just spent on things that don’t pay it back. A five-minute Bite that makes you better in a conversation on Friday pays it back.

What a chatbot gives you

The salary cap is a limit on the total amount of money that teams can spend on player salaries, and it is set each season as a percentage of basketball-related income, which includes national television deals, ticket sales, and merchandise, though the way it is calculated has changed several times through collective bargaining, and teams can exceed the cap through a series of exceptions such as the mid-level exception, the bi-annual exception, and Bird rights, which allow a team to re-sign its own free agents above the cap, while the luxury tax is a separate threshold above the cap at which teams begin paying a penalty for every dollar spent, with repeater rates for teams that stay over for multiple seasons, and the two aprons introduced in the most recent agreement add further restrictions on trades and signings for the highest-spending teams, which is why you will hear analysts say a team is "capped out" or "in the second apron" even though neither phrase appears anywhere in the actual document, and the practical effect for a fan is that roster moves in the offseason are constrained less by whether a player is good and more by whether a contract fits, which is also the reason that draft picks and minimum contracts are so valuable, since they provide production at a cost that does not count heavily against these thresholds, and

You read it. You skim it. By Friday, it’s gone.

Then Keep Sharp brings each idea back right before you’d forget it.

Two doors in. One loop.

Bring the material you already have, or describe what you want to know. Either way, Axo builds a Path with the same shape: four units, sixteen Bites, a capstone, and review that keeps it.

Bring your own.

Paste a document, a PDF, a transcript or your notes. Axo rebuilds it into units, Bites and questions. It never adds a fact that isn’t in your file, and every question names its page.

Over 30,000 words becomes a two-Path series instead of an error. A file it can’t read gets named, not buried.

Say what you want to know and by when. A short chat pins down your goal and your level, then Axo writes a Path that’s current and scoped to you, and tells you what it drew on.

Enough NBA for Friday. HVAC basics for a first job. Contract law for a freelancer. Whatever it is, it ends.

What do you want to know, and by when?

Enough NBA to keep up with my friends. Game’s Friday.

Got it. Casual fan, this season, about two hours. Your Path is ready.

Every Path has an end.

Most online courses finish under 15 percent. Ours are built to be finished: a fixed shape, a visible rail, and a capstone you have to pass.

Step 1
Bring or ask.
Paste what you have, or tell Axo what you want to know and by when.
Step 2
Path is built.
The outline in ten seconds, Bite 1 in twenty. The rest builds while you start.
Step 3
Bites.
Five to seven minutes each. A short read, then questions. XP only for real recall.
Step 4
Finish line.
A capstone across every unit, a badge, a share card, and an honest ending.
Step 5
Keep it sharp.
Spaced review of what you learned, or Go Deeper into a new Path one level down.

A Path: Four units, about two hours. A hard cap. Longer topics become a series, each level finishable alone.
A unit: Four Bites and a unit check of eight to ten mixed questions.
A Bite: Five to seven minutes, three to five ideas, six to ten exercises. One idea per screen.
The capstone: Fifteen to twenty questions across every unit. Score 80 percent to earn the badge. Retries are free and pull new questions.

Learn something about an axolotl in three minutes.

One Bite. Five questions. No sign-up. It’s the fastest way to feel what Axo does, and you’ll leave knowing why scientists are obsessed with this animal.

Start the Bite

Built on how memory actually works.

Retrieval beats rereading. Spacing beats cramming. A little difficulty is what makes memory form. Every exercise and every schedule in Axo traces back to one of eight findings that have held up for decades.

Retrieval practice: Every Bite ends in questions, not a summary. Keep Sharp is all retrieval. There is no “review the text” screen without a question attached.
Spaced repetition: Each concept gets a memory score and a next-review date. Keep Sharp pulls what is due today, across all your Paths.
Desirable difficulty: Fill in the blank comes before multiple choice. Review sessions mix topics. Axo tells you when a question is supposed to feel hard.
Interleaving: Keep Sharp interleaves concepts from different units and Paths. Capstones mix every unit.

All eight principles, and what we refuse to do

How fast you forget, and how spacing changes it.

A model, not a measurement. Each review resets the curve and flattens the next one.
