Photosynthesis converts light energy into chemical energy. Chlorophyll absorbs light, and the plant uses water and carbon dioxide to produce sugars. Oxygen is released as a by-product. The light-dependent reactions and the Calvin cycle carry out different parts of this process.
Drop a lecture recording into Cockatoo and get a full transcript with each speaker identified separately.
The text appears in an editable browser window, ready for corrections or export to your notes app.
Canvas, the built-in editor, lets you fix names, add formatting, and click once to generate a summary that pulls out key points.
No separate app to install: edit and summarize in the same tab where your transcript appears.
A two-hour lecture file uploads, transcribes with speaker labels, and opens in Canvas where you can read, search, and edit the full text.
Click the summary button and the AI condenses the transcript into study notes: definitions, key arguments, and action items.
Edit speaker names, fix terminology, then export the cleaned transcript or summary to your notes app or download as a document.
Even the best transcription model will miss a professor's name, a technical term, or a brand mentioned once in passing.
Free auto-captions give you a rough draft that still requires 20 minutes of cleanup per hour of audio, erasing the time you thought you saved.
A lecture summarizer that includes an editor lets you correct those errors in context before you export, so the summary reflects what was actually said.
Photosynthesis converts light energy into chemical energy. Let's look at where each stage takes place.
So the light-dependent reactions happen in the thylakoid membranes, and the Calvin cycle happens in the stroma?
Exactly. Keep those two locations in mind as we follow how energy moves through the process.
Upload a lecture that switches between English and Spanish, or a conference talk in French, and Cockatoo transcribes it without requiring you to select the language in advance.
The engine detects and handles dozens of languages, so you spend time studying instead of configuring settings.
