An extension of Bee, for students with ADHD

When the plan breaks,
rebound.

Bee hears your day. When something changes, Rebound re-plans the hour, syncs the next step back to Bee, and turns what you learned into quick quizzes and short explainer recaps for your TV, phone or Alexa.

Every app helps you plan your day. None of them stay with you when the plan breaks. And for *6.1 *million kids in the US with ADHD, it breaks every day.

Bee

Bee hears your day.

Bee is the personal AI you wear. It keeps your conversations, photos, facts and todos in its own app.

Rebound reads that same data through the Bee API and does one specific thing with it: helps a student with ADHD act on what just happened.

Hear

Say it out loud.
That's the input.

On the way to class, you ask Bee for email updates. It tells you class is cancelled.

"Oh, my class got cancelled. I don't know what to do with my free time."

You didn't open an app. Rebound heard it through Bee.

Re-plan

The hour,
re-planned.

Your calendar rearranges on its own. The freed hour now holds the thing due tonight: Draft problem set 3. Lunch and lab stay put.

One line, one step, and a Start button. The rest can wait.

Today's calendar rearranged: Draft problem set 3 moved into the freed 10 AM hour
Sync

Back on your wrist.

The new step syncs to Bee as a reminder through the Bee API, so it finds you later without you having to remember it.

Just what's next, waiting where you'll see it.

Learn

Learn from
what Bee saw.

Slides you photographed with Bee and lectures it heard become short quiz rounds, with your own photo as the question.

Rounds are tuned by your Bee facts and by Apple Health: after a short night you get three short questions, slide photo first.

Bee heard the talk.
Rebound made the explainer.

On Friday, Bee sat in on a Meta data science talk and photographed two slides. Rebound turned that memory into a narrated explainer with quick checks built in, ready on the TV, the iPhone and as a podcast episode.

On the couch, in the app,
or out loud.

One storyboard makes two things: the explainer video and the same narration as a podcast episode. Pick whichever fits the moment.

Fire TV

Rebound TV

A Vega OS app for Fire TV. Your recaps is the first row, the newest recap rotates in the hero, captions are on by default, and it ends on "Practice 3 questions on your phone, or call it done for tonight."

Echo · Alexa app
"Alexa, open Rebound review."
Here's your newest recap: Thinking is the bottleneck, from Friday's Meta data science talk.
"Alexa, ask Rebound review to play my ML recap."
Alexa + podcast

Hands free.

The Rebound review skill plays your newest recap, or the newest for a class, and pauses, resumes and skips like any audio.

The same episodes come as a private podcast feed, so they also play in any podcast app, with chapters.

iPhone

In the Rebound app.

Recaps sit in Learn, right under your quests. Watch plays the video full screen with captions and chapters. Listen plays the episode with the screen off, from the lock screen.

The pause in each recap asks a question and counts down five seconds before it shows the answer.

Class and exam recaps

After class.
Before the exam.

Right after a class, tap 90-second recap for the two or three ideas that matter most. With an exam coming up, Exam pack pulls together every session for that course.

Recaps spend their time on the ideas your quiz rounds say are ready to refresh, and give the ones you know well a single line.

When an exam is a week away, a fresh exam pack is waiting at 7 a.m.

How a recap is made

From what Bee heard
to a video, in minutes.

Every model runs on Amazon Bedrock. Claude writes the story; code handles the timings, crops and files.

01 · GATHER

What Bee kept

The talk's ideas and the slides Bee photographed, from the same quiz state that runs your rounds.

02 · STORYBOARD

Claude writes it

Claude Sonnet 4.5 writes one core idea, one analogy from your life, a quick check and a takeaway. A validator checks length, copy and quotes.

03 · VOICE

Nova 2.5 Sonic

Amazon Nova 2.5 Sonic voices each scene. Its own transcript must match the script at 95% or the clip is redone.

04 · VISUALS

Your slide, cropped

Only the slide region that matters is kept. The full photo is deleted, and photos with people are never used.

05 · RENDER

Remotion

Stills first, checked by eye, then a 1080p encode with captions, chapters, a poster and the podcast MP3.

06 · PUBLISH

Everywhere at once

Recap Studio on AgentCore keeps it private with signed links and lists it for Fire TV, the iPhone, the podcast feed and Alexa.

The bee-recap skill

Make one from your own agent.

The same pipeline ships as an agent skill. Ask Claude Code for "a 90-second recap of that talk" or "an exam pack for my midterm", and it writes the storyboard while the script does the rest.

br serve puts the result on Rebound TV and any player on your network.

A photo alone rarely sticks.

Students photograph slides to come back to later. Rebound turns those photos into practice, using four of the best-supported study strategies.

Retrieval practice

Recalling an answer beats rereading it.

Roediger & Karpicke, 2006

Spaced review

Short rounds across days, not one long cram.

Cepeda et al., 2006

Dual coding

Your own slide photo plus words, together.

Mayer, 2009

Sure or unsure?

Confident mistakes, once corrected, stick best.

How it works

Built on Bee.
Running on AWS.

Live Bee data in, one next step out, written back to Bee.

01 · HEAR

Bee stream

bee stream runs on ECS Fargate and passes what Bee hears to the ingest Lambda.

02 · NOTICE

A plan just broke

Claude Haiku 4.5 spots the moment: a meeting running over, a slow start, "where was I?", or "my class got cancelled".

03 · RE-PLAN

Claude in Bedrock

Claude Sonnet 4.5 on Amazon Bedrock re-plans the next hour around what can't move.

04 · SYNC

Back to Bee

The new step lands in Bee as a reminder through the Bee API, and on the iPhone.

Your Bee
stays yours.

Rebound works on top of the Bee app, not instead of it. It reads only what it needs and keeps as little as it can.

Token in Secrets Manager

The Bee token lives only in AWS Secrets Manager. It never ships in the app.

Health stays on the iPhone

Sleep, HRV and steps are read on the device. Only the derived numbers are sent.

Counts, not transcripts

Talk-time features keep counts only. The text is discarded.

Places, not tracks

Arrival cues are opt-in. Only the centre of a place you label is kept, never a location history.

So let's rebound,
in life, with Bee.

Try it on your iPhone. No Bee? Tap Try the demo story on the first screen.
