Photosynthesis
Photosynthesis converts light energy into chemical energy inside the chloroplast.
Light-dependent reactions (thylakoid membrane): water is split, O₂ released, and the energy is stored as ATP and NADPH.
Calvin cycle (stroma): spends that ATP and NADPH to fix CO₂ into G3P, the sugar precursor.
Chlorophyll absorbs red and blue light and reflects green, which is why leaves look green.

How it works

Three steps. That's it.

01
Step 01

Drop in your notes

Paste typed notes, upload a PDF, or write in the editor. Even messy lecture notes work.

02
Step 02

AI builds your kit

One click turns your material into flashcards, practice tests, study guides, and a podcast.

03
Step 03

Review until you've got it

Spaced-rep flashcards, calibrated tests, and a tutor that sees what you're looking at.

Features

Built around how you actually study.

Twelve tools, one subscription. Each one earns its spot: built for a specific study moment, tuned to deliver in one click.

Lecture Recorder

Record class live (or upload a recording you already have). AI transcribes the audio and structures the raw transcript into headings, bullets, and bolded key terms: saved as a fresh note in your library, tagged to the class.

  • Live recording from your laptop or phone: no app to install
  • AI strips fillers, false starts, and off-topic logistics
  • Headings, bullet lists, key terms bolded: reads like notes from a friend
  • Up to ~100-minute recordings at 32 kbps mono
Homework Helper

Snap a photo of any problem. Get a real solution.

Camera, drag-drop, or paste a screenshot with ⌘V. The AI reads the problem from the image: math, chemistry, physics, code, and walks you through each step with the reasoning. Not just the final answer.

  • Phone camera (rear lens), drag-drop, or clipboard paste
  • Identifies the subject and uses subject-specific conventions
  • Numbered steps with titles + reasoning, answer highlighted
  • Image solves don't count against your monthly AI budget
Notes

Your notes do the boring writing for you.

Highlight any sentence and tell Allie to expand, simplify, rewrite, or restructure it. Streams in like ChatGPT: without ever leaving your document.

  • 9 instant AI text actions (expand, shorten, rewrite, …)
  • Per-selection font, highlight, line-spacing that actually works
  • Accept · regen · discard on every AI suggestion
  • Autosave every keystroke
Practice Tests

Quizzes that feel like the real exam.

AI generates multiple-choice, true/false, short answer, and essay questions that test real understanding, not just memorization. Each question targets a different level of difficulty so studying with these maps to how you'll actually be tested.

  • Difficulty ladder: recall → application → analysis
  • Wrong answers that are actually plausible, not throwaway filler
  • Mark questions for review and retry only the ones you missed
  • Honest grading: a 78 stays a 78, no inflation
Allie Assistant

An AI that already knows what's on your screen.

Floating chat one click away. Allie sees your current note, your active essay, your calendar, so you never have to re-explain context. She can also update your calendar for you.

  • Sees the page you're on (no copy-paste context)
  • Reads notes, essays, and tests without you uploading them
  • Can add or edit calendar events on command
  • Smooth streaming output: no burst-shot text
AI Podcast

Your notes turned into a podcast you can actually listen to.

Drop in any note, pick a length, get a two-host conversation that sounds like two people, not robot narration. The transcript scrolls along sentence by sentence as the audio plays, so you can read while you listen.

  • Two real-sounding host voices, not a single monotone narrator
  • Pick 5, 10, or 15 minutes
  • Transcript highlights the current sentence: tap any line to jump there
  • Listen on walks to class instead of re-reading
Syllabus Calendar

Drop in a syllabus. Get a populated semester calendar.

Upload your syllabus PDF or paste the raw text. AI extracts every class meeting, deadline, exam, and project: color-coded by class, viewable as a month grid or daily list.

  • Works with PDFs or pasted text
  • Pulls deadlines, exams, classes, and meetings automatically
  • Color-coded by class so the calendar reads at a glance
  • Smart "What's next" list on your dashboard so nothing slips
Essays

Write the essay yourself. AI helps when you're stuck.

Start with a blank canvas and use the same 9 AI text actions as Notes. Or generate an outline-to-draft if you're starting from zero. Built-in grader with a calibrated rubric: and a slot for your professor's rubric too.

  • Write-yourself OR full AI-generated drafts
  • AI grader with donut score ring + per-criterion feedback
  • Drop in your professor's rubric for accurate scoring
  • Real .docx export (not fake HTML)

Photosynthesis

Light-dependent reactions occur in the thylakoid membrane. Photosystem II splits water, releasing O₂; excited electrons pass down the transport chain to Photosystem I, where NADP⁺ is the final electron acceptor, forming NADPH. The proton gradient drives ATP synthase.

The Calvin cycle then uses that ATP and NADPH in the stroma to fix CO₂ into G3P.

Quiz me on my notesAdd an event to my calendar
Quiz me on the light reactions, then block out a review on my calendar for Thursday night.
On it. Reading your Photosynthesis note now. First question: in the light-dependent reactions, what molecule is the final electron acceptor?
NADP⁺
Correct. It becomes NADPH for the Calvin cycle. Two more coming. And your review is on the calendar:

MayaOK, cellular respiration. Why does anyone need 38 ATP?
JordanBecause every muscle twitch, every thought, spends it. Glycolysis alone only nets two.
MayaTwo! So where do the other thirty-something come from?
JordanThe electron transport chain. Oxygen pulls electrons through it, and that gradient powers ATP synthase.

The New Deal’s Legacy
HIST 210 · 1,120 words · Professor’s rubric attached

Roosevelt’s New Deal is usually judged by whether it ended the Great Depression. That is the wrong question. Its lasting achievement was institutional: Social Security, federal deposit insurance and the SEC still structure American economic life ninety years later.

Expand · streaming
The Works Progress Administration alone employed roughly 8.5 million people between 1935 and 1943,
building 650,000 miles of road and 78,000 bridges. Critics called it make-work; the numbers say
otherwise. The programs did not end the Depression, but they redefined what citizens could expect
from a federal government, a shift that outlasted every individual agency.

(Kennedy, Freedom from Fear, 1999, p. 252)

Built efficiency-first

Same power as the big AI tools. Smaller footprint.

Lecture transcription runs on Groq's LPU hardware, the same Whisper model OpenAI uses, ~10× faster and ~10× more efficient per minute of audio with the same accuracy. Every other AI call is routed to the smallest model that gets it right, and our prompts are tuned to return finished output in one call instead of fifteen. 1% of every subscription goes to verified climate work.
