## Useful for

- Take lecture notes on top of PDF slides directly in the browser
- Export a notes page to PNG or the whole notebook to PDF with vector ink
- Save a notebook to a .brainotes file for backup or sharing

## Why it’s here

- Star-counter measurements on 2026-10-12 (UTC), 01:37–03:04: 3 → 7 stars (+4). This is the change over that interval.
- Estimated end-of-day forecast: about +10 stars, using observed gains and the previous day.
- The repository is 7 days old and already has 7 stars. With less than two weeks of history, there's no usual pace to compare the spike against yet.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 1
- Issues and pull requests: 0
- Watchers: 0
- Average over the last week: 2 per day
- Usual pace: too little history (under two weeks)
- Stars in the last hour (measured): 3

## Stars per day, last 8 days (oldest → newest, today is partial)

2026-10-05 … 2026-10-12: 1, 1, 0, 0, 1, 0, 4, 4

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
