Buddy 2.0, your screen, explained. Asking while Buddy is still talking: in 1.5 you held Control and Option again, which stopped the answer; in 2.0 you just say: Wait, why does high start at the length of the list?

Download Buddy for Mac

macOS 14.2 or later Apple silicon and Intel 9.8 MB download Free and open source, MIT

Ask about anything on your screen. Buddy explains it out loud and draws on it while it talks.
2.0 is the biggest release yet: learn, get things done, fix errors, review your work, and remember all of it.

Talk over it

While Buddy explains, just speak. No keys, nothing to switch on.

Say Buddy
"Wait, why does high start at the length?" Stops and answers your question
"Hold on" Pauses mid-sentence
"Go on" Carries on from where it stopped
"Slower" Slows the rest of the answer
"Go back" Says the last sentence again
"Say that again" Replays the whole answer, free

Note

The microphone is open only while an answer plays, and the notch shows a mic whenever it is. Esc or Stop closes it. Buddy's own voice is filtered out, so it never cuts itself off.

Learn anything from scratch

Say "teach me TCP from scratch" and the screen turns into a whiteboard. Buddy teaches it part by part, over as many questions as you like.

A whiteboard titled How tcp works: client and server boxes, the three-way handshake as a group of three steps, a table of data segments, and the Today's board card with the part being taught

Teach it back

Say "let me explain binary search back to you" and explain it out loud. Buddy draws what you said in purple, exactly as you said it, then marks the gaps in red.

The board titled You explain: binary search. The student's explanation drawn in purple; takes linear time ringed in red with logarithmic time, log n beside it; the stopping rules they left out in dashed red

You said Buddy marked
"You keep halving, so it takes linear time" Ringed, with logarithmic time, log n beside it
Nothing about when it stops Middle equals target: found, stop and range empty: not found, dashed

What you got right counts as remembered; what you missed comes back sooner on the map.

Explain the error you just hit

When an error appears in a terminal or editor, a soft red glow shows under the notch. Tap Control + Option, or hover and pick Explain this error, and Buddy rings the line that caused it. Nothing is sent anywhere until you ask, and the same error is never offered twice.

On errors written after the recognizer was built
Errors recognized 20 of 20
False alarms on output that only looks like an error 0 of 18
Rings the right file and line 17 of 17

Knows what the lecture said

Watching a video lecture? Ask "what did she mean by that?" and Buddy knows the last minute of what was said, from the page's transcript, or from the video's own sound once you allow it. Never your microphone, never calls or meetings, kept in memory only.

A notebook that writes itself

Every lesson becomes a page: its drawing, a sharp picture of what it marked on your screen, what Buddy said, and links to teach it back. Search it, and export a day, a range or everything as a PDF in the background.

The Notebook window: lessons down the side grouped by day, and the page Binary search high bound with its trace card of searching for 10 in 3, 7, 9

A map of what you know

Every idea Buddy has taught you, joined to related ideas, coloured by how well you still remember it: Strong, Fading, or Time to review. Click one for a quick recap or to teach it back.

The Map of what you know: ideas such as idempotency keys, transactional outbox, off by one error and binary search bounds as capsules joined by lines, in two named clusters

Answers the size of your question

You said Before 2.0 Now
"hello buddy" Started describing your screen and ringing things "Hey Rajeev, good to see you."
"what's the time complexity of binary search?" Sized as a long answer Two sentences, one ring on the line that halves
"what all can you do?" A vague list A card of all five areas, each with one thing to try

A card titled five things, on whatever you have open: learn, get it done, fix, review and remember, each with a phrase to try, and a note saying interrupt me anytime, just talk

A new look

The notch, Settings and setup are rebuilt. Settings is eight controls with nothing to scroll. Hover Spent today to see what Claude, Gemini and Deepgram each cost, and what for. Setup ends by checking your shortcut and microphone for real. How to use Buddy now opens the guide.

Also in this release

Area What changed
First word sooner The screen is read while you are still talking
Point at what you mean Select text, or rest the pointer on a line while you hold the keys, and that is what "this" means
Marks follow Rings stay on their line when you scroll, move or resize the window
Draws only when it helps Short answers no longer come with a card
Replay Plays the last answer again, voice and drawing, at no cost
Steadier Recovers from sleep, a changed microphone or speaker, and a slow model; a stalling model is set aside for longer each time it keeps failing
Fixed A crash when an error offer appeared; a crash on an answer of only drawing tags; a lesson could overwrite an unrelated idea in memory
