Membrane-bound receptors respond to ligand binding through a conformational change in the transmembrane domain.

This conformational change exposes an intracellular binding site, allowing the associated G protein to exchange GDP for GTP and dissociate into its active subunits.

The activated subunits then regulate downstream effector enzymes, producing second messengers within milliseconds...

Clear, natural-sounding narration built on production text-to-speech, with adjustable speed and a choice of voices.

Ask Your Document

Tap any ambiguous sentence mid-audio to instantly ask questions, get analogies, or distill proofs without leaving context.

Pick Up Anywhere

Close the app mid-paragraph and reopen exactly where the audio stopped, on the same sentence.

Active Reader Sync
Bio_Cellular_Signaling.pdf

Primary messenger ligands initiate membrane signal cascades by binding allosteric receptors.

The secondary messenger cyclic adenosine monophosphate (cAMP) activates protein kinase A, amplifying intracellular transcription downstream.

This activation pathway is tightly regulated through phosphodiesterase enzymatic hydrolysis.

Bimodal Learning

Read with your ears,
follow with your eyes.

Dense reading invites mind-wandering, and you lose the thread halfway down the page. LumiNote narrates the text while highlighting each word as it is spoken, so your eyes have something to follow.

Works the same on a medical paper, a law brief, or an end-of-semester textbook chapter — anything you can open as a PDF.

Instant Understanding

Stuck on a paragraph?
Just ask.

Dense jargon shouldn't stall your session. Tap any sentence or formula and LumiNote explains it using the document you uploaded, and shows the page its answer came from so you can check it.

Explain what "heuristics" implies in this cognitive model context?
In this paragraph, heuristics refers to subconscious decision shortcuts utilized under acute cognitive load, trading absolute probabilistic precision for rapid processing efficiency.

Questions

Before you sign up

LumiNote is still in development. Here's where things stand.

When does LumiNote launch?
We're targeting the first week of October on both iOS and Android. Join the waitlist and you'll get one email the day it's live.
What does it cost?
There's a free tier you can study with, Pro at $15 per month, and Ultra at $25 per month for heavier reading loads. Full breakdown is in the pricing section.
What kinds of PDFs work?
Any PDF with a real text layer — textbooks, journal articles, lecture slides, case briefs. Scanned pages without OCR won't narrate correctly.
Does it work offline?
Once a document has been processed, playback works without a connection. The initial processing and the in-document Q&A need to be online.
Is my document uploaded anywhere?
Your PDFs are stored in LumiNote's own cloud storage and nowhere else. We don't sell your documents, share them with advertisers, or use them to train anything. To produce narration and answer questions, the text of the page being read is sent to our speech and AI providers for processing — that's what generates the audio and the answers, and nothing is kept by them beyond that request.
Can I get in early?
Yes. Closed testing needs a group of testers before launch. Join the waitlist and mention you'd like to test — early testers get direct input on what gets built next.
