See Ace write your course

Every feature in 44 seconds: a path that starts at your level, lessons you can question, hands-on practice, hints, levels that never run out and interview prep.

How it works

Read it, question it, try it, keep going

No pre-written course. Claude writes every lesson for you and adapts to every answer you give.

1

Start where you are

Pick a subject and tell Ace how comfortable you are with it. Your Level 1 starts right there, so you never re-learn what you already know.

2

Learn by doing

Each lesson is a short read you can question, a hands-on warm-up, then adaptive practice. Every answer updates your mastery, so the next lesson targets your gaps.

3

Never stop climbing

Spaced reviews keep what you've learned fresh, and when you finish level 10 Ace designs the next levels. Your path grows with you.

Let Ace show you around

Keep scrolling. Ace zooms in on each screen and explains what you're looking at.

Your path

A path that starts at your level

Tell Ace how comfortable you are with a subject and your Level 1 is pitched right there. The next topic is always one click away.

New

Lessons you can question

Every lesson opens with a short read written for your gaps. Highlight anything you don't get and ask Ace about it.

  • Explain more, example, simplify in one click
  • Or ask your own question in a side panel that knows the lesson
New

Learn by doing

After the reading comes a hands-on warm-up: flashcards you flip, worked examples revealed step by step, and quick “predict what happens” checks.

New

Play with the ideas

Sorting challenges and instant feedback turn passive reading into active learning. Mistakes here are just part of learning.

New

Hints when you need them

Seven question types, graded instantly. Open answers are reviewed by Claude for meaning, not wording. The hint button counts down so you try first.

New

Go back any time

Review any earlier answer mid-lesson, re-read the lesson in a side panel, and get wrong answers back for a second chance at the end.

New

Learning with no ceiling

Ten core levels take you from where you are to expert depth. Finish them and Ace keeps building: deeper internals, specialisations and what's new.

FAQ

Good questions

What do I need to use Ascend?

A Claude Code sign-in (Pro, Max, Team or Enterprise; run claude in a terminal and use /login) or an Anthropic API key, which you can add in Settings. Ascend bundles Claude Code, so there's nothing else to install.

Does it cost anything to use?

Ascend itself is a free download (if it helps you, you can support it via UPI). Lessons, grading and practice run on your own Claude account, so they count towards your plan's usage, or your API bill if you use a key. Settings shows how much it has used, and a lighter model or “Faster” mode stretches it further.

I already know the basics. Do I have to start from scratch?

No. Tell Ace you're “Comfortable” or “Advanced” and your Level 1 starts there, skipping what you already know. You can also test out of any level by passing its checkpoint.

What happens after level 10?

Your path keeps growing. The first 10 levels are the core path; once you finish them, Ace designs the next levels (deeper internals, specialisations and current practice) around what you've mastered and where you're still weak.

Can I use it to prepare for interviews?

Yes. Paste a job description and Ace researches the company, maps your skill gaps and builds a day-by-day plan. Mock interviews (technical, behavioral, system design or rapid fire) are scored like a hiring panel, with ideal answers.

Where is my data stored?

On your computer, in a local file with a daily backup. Settings has export, import and reset. Your prompts go to Claude to generate lessons, exactly as when you use Claude Code yourself.

Why does Windows or macOS warn me when I open it?

The builds aren't code-signed or notarized yet, so your system asks you to confirm the first launch. The download section above shows the one-time steps. Every build is produced by GitHub Actions straight from the public source code.
