Drop a technical video. Get a personal knowledge graph you can query from Cursor or Claude. The graph you get depends on what you are looking for.

So you stop re-watching, re-scrubbing, and re-googling the same video.

Source videoLet's build GPT: from scratch, in codeWorks on any technical video. We chose this one because it touches all four brains.

Software Engineer

Looking for the code, the libraries, the how-it-is-built.

19 nodes7 tools

AnchorAdamWTool

›Show me every tool and the attention head implementation.

Code, lifted verbatim

class Head(nn.Module):
    def __init__(self, head_size):
        super().__init__()
        self.key = nn.Linear(n_embd, head_size, bias=False)

ML Researcher

Looking for the lineage: papers, datasets, who proved what.

16 nodes3 papers

AnchorAttention Is All You NeedPaper

›List every paper this references and the result it cites.

Citation with the formula it defines

\mathrm{Attention}(Q,K,V)=\mathrm{softmax}\left(\frac{QK^{T}}{\sqrt{d_k}}\right)V

Attention Is All You Need (2017)

Lineage, not recency: it maps what the work descends from, not the latest headline.

YouTube Creator

Looking for the format: hook, pacing, the production moves.

12 nodes3 techniques

AnchorAndrej KarpathyChannel

›Break down the hook and the editing techniques used.

The opening hook, with its timestamp

“published on the Andrej Karpathy channel

0:00

The anatomy of how this video was made, run on a channel catalog to map the creator.

Journalist

Looking for the people, the stakes, who is on record.

18 nodes5 people

AnchorAndrej KarpathyPerson

›Who is quoted, and where do they disagree?

On the record, attributed and timestamped

LeCun counters that self-supervised objectives matter more than the architecture

8:00

Breadth over verdict: it surfaces who is on record, not who is right.

Same video, four different graphs

Software Engineer leans into 7 tools.
ML Researcher leans into 3 papers.
YouTube Creator leans into 3 techniques.
Journalist leans into 5 people.

The graph the Software Engineer profile builds from this one video. Drag a node to pull it, drag empty space to orbit.

How it works

You set your profile once

The four brains above show what a profile changes. In the product you pick yours once and it shapes every video you process, it is not a per-video switch. Change it any time and new graphs follow.

One video. Your graph depends on you.

Drop any YouTube link and Deepwatch builds the graph your profile calls for, then exposes it to Cursor, Claude Desktop, and Claude Code over MCP.
