The problem
You don't need another summary. You need help understanding the hard parts.
The unfamiliar term. The dense paragraph. The figure you can't quite parse. The equation you can read, but not yet interpret.
Without draftn
PDF viewer, chatbot, notes app, Google. You spend too long chasing down definitions across different tabs, and by the time you find the answer, you've lost your original train of thought.
With draftn
"I highlighted 'variational inference' and got a clear explanation at my level right there. No extra tabs, no lost time, no forgotten context."
Without draftn
Copying text into a chatbot strips away the document structure. You get generic summaries with no citations, meaning you have to spend even more time trying to verify what's real.
With draftn
"It showed me the exact paragraph and page it was using. I could click through and verify it myself in seconds."
Without draftn
General AI tools are built for business reports. They oversimplify concepts, ignore equations, and leave you struggling to actually relate the findings to your own research.
With draftn
"I got through 6 papers today. Not generic summaries - I actually understand the methods and findings, and can confidently link it back to my own work."
Without draftn
I can see this figure is the core of the method, but I'm struggling to follow the pipeline and what each stage is doing.
With draftn
"I highlighted the figure and got a clear walkthrough of the pipeline, what each stage does, and how it fits into the paper's method."
How it works
Read. Select. Understand.
Three simple steps to go from confused to confident.
2
Select exactly what you need help with
Highlight a single term, a sentence, or a paragraph. Choose to Explain, Summarise, or Define. You control the scope - the assistant stays grounded in what you selected.
3
Get answers grounded in your document
Every response is derived from the paper itself, with precise page citations you can click to jump straight to the source. Full LaTeX and markdown support for clean notation.
Features
Everything you need to deeply engage with complex material.
Selection
Select exactly what matters - in the paper or in the response
Highlight a single word, a sentence, or an entire passage in the PDF.
Choose to Explain, Summarise, or Define it - and get a response grounded in that exact selection.
The same precision extends to the assistant's responses. See a term in an explanation you don't follow? Select it and ask again. Read, ask, understand, dig deeper - without ever leaving your document.
Attention Is All You Need (2017) — Abstract
The dominant sequence transduction models are based on complex recurrent or convolutional neural networks that include an encoder and a decoder. The best performing models also connect the encoder and decoder through an attention mechanism. We propose a new simple network architecture, the Transformer, based solely on attention mechanisms, dispensing with recurrence and convolutions entirely. Experiments on two machine translation tasks show these models to be superior in quality while being more parallelizable and requiring significantly less time to train.

•
AlphaFold utilizes the Evoformer architecture to simultaneously process multiple sequence alignments (MSAs) and pairwise residue relationships, followed by a Structure Module that uses Invariant Point Attention (IPA) to predict 3D coordinates.
•
The system is trained through self-distillation — incorporating high-confidence predicted structures from unlabeled sequences back into the training set — and a BERT-style objective that masks residues to help the network learn evolutionary patterns.
•
It achieves high accuracy (median 0.96 Å r.m.s.d.95, a measure of average distance between atoms) by using the Frame-aligned point error (FAPE) loss, which ensures atoms are correctly positioned relative to local residue frames.
Citations
Every answer traces back to the source
Responses are grounded in your document, not generated from training data. Every answer includes clickable page citations - click one and the viewer jumps to the exact passage with the relevant text highlighted.
Your conversations are saved per paper. Come back days later and pick up exactly where you left off.
Technical rendering
Equations and notation, rendered properly
Responses display LaTeX, mathematical notation, and formatted tables exactly as they should appear. No broken symbols, no garbled formatting - just clean, readable answers that match how your field actually writes.
Adam: A Method for Stochastic Optimization — Section 2
As explained in section 2, Adam utilizes initialization bias correction terms. Let be the gradient of the stochastic objective , and we wish to estimate its second raw moment using an exponential moving average of the squared gradient, with decay rate . The update at timestep of the exponential moving average = · + (1 − ) · can be written as a function of the gradients at all previous timesteps:

Cryogenic electron microscopy maps are three-dimensional reconstructions of macromolecular structures, such as proteins, created by capturing images of samples that have been flash-frozen at extremely low temperatures to preserve their native state. These maps provide a density visualization that researchers use to determine the precise spatial arrangement of atoms within a biological molecule. In this research paper, the authors note that AlphaFold's high-accuracy predictions have already assisted the experimental community in interpreting these complex maps.
Depth control
Answers that match how much you already know
Switch between undergraduate and graduate-level explanations with one click. New to the topic? Get clear foundations. Deep in your research? Get the full technical detail.
Visual understanding
Click any figure. Ask what it means.
Select any diagram, chart, or figure in the paper and ask questions about it. The AI explains what's shown - architecture diagrams, flow charts, data plots - in the context of the paper it comes from.
No more staring at Figure 3 wondering what the arrows mean.

This diagram from the AlphaFold research paper illustrates how the accuracy of protein structure predictions depends on the amount of available evolutionary information. The y-axis measures accuracy using lDDT-Cα and the x-axis represents MSA depth (Neff).

Built for how you actually work.
🎓
For Students
Make sense of your readings, week by week
You've been assigned a dense 30-page paper the night before your tutorial. You don't need a summary - you need to understand the core argument well enough to discuss it.
Upload the paper, select the passages that lose you, and get explanations at a level that actually helps. Organise readings by unit. Search past conversations when exams roll around.
🔬
For Researchers
Go deeper, faster - without losing rigour
Working through a stack of papers for your literature review. Some are in your field; others are adjacent disciplines where the terminology is unfamiliar.
Import from arXiv. Use page focus to zero in on methodology sections. Toggle to Technical mode when you need the full detail. Export threads as research notes.
📖
For Academics
Stay current across disciplines, not just your own
Reviewing a paper from an adjacent field for an interdisciplinary project, or preparing to teach material outside your core specialisation?
Orient yourself on unfamiliar terminology and methods. Toggle depth depending on whether you need a high-level orientation or a detailed breakdown. Every answer is verified with citations.
Why this is different
Not another generic PDF chatbot.
Most AI reading tools are built for anyone reading anything. We built this specifically for people who read technical, complex material and need to genuinely understand it.
