How it works

From an idea to a filming plan

The same path the app guides you through, step by step.

1

Pick a niche

Browse the built-in catalog of known niches, with risks and starting searches.

2

Collect a real sample

Run an official YouTube search with your key, or import data you’re allowed to use.

3

Study outliers and sources

See which videos beat their own channel, and open the source of every number.

4

Plan ten videos and a script

Save ten production briefs, then turn one into a structured script draft.

Evidence, not guesses

Every number has a source

Nishio shows what it measured and what it couldn’t. No private analytics, no invented figures.

  • Every figure links back to the video or import it came from.
  • An outlier multiple needs enough comparison videos from the same channel and format.
  • Approximate values are marked; missing metrics stay empty, never zero.
  • CTR, retention, RPM and revenue are never shown — they are private to channel owners.

Stays in a local database you can back up or delete

The only external quota is the one Google gives your own YouTube API key. We never see it.

Private by design

Your research stays on your computer

Stays local

Your account, workspaces, saved videos, notes, plans, scripts and reports live in a local database on your machine.

Goes to YouTube — only when you ask

Official searches are sent to Google’s YouTube Data API with your own key, and only after you confirm.

Optional

Local AI through Ollama and pairing the browser extension are both opt-in and stay on 127.0.0.1.

FAQ

Questions

Is Nishio free?

Yes. Download it for macOS, Windows or Linux and use it without an account in the cloud.

Do I need a YouTube API key?

Only for official online search. The catalog, imports, notes, plans, scripts and reports work without a key. A key is free from Google Cloud; add it in Settings → YouTube.

Where is my data stored?

In a local database in your user folder: ~/Library/Application Support/Nishio on macOS, %APPDATA%\Nishio on Windows and ~/.config/Nishio on Linux. Use File → Open data folder in the app.

Why isn’t the extension on the Chrome Web Store?

It isn’t published there yet. You install it from a ZIP with “Load unpacked” — it takes about a minute and the steps are on the Extension page.

Why does Windows or macOS warn me?

The Windows installer isn’t code-signed yet, so SmartScreen asks you to confirm (More info → Run anyway). On macOS, choose “Always Allow” when the app asks to use the keychain for your encrypted key.

Does it work offline?

Yes for everything stored locally. Online search, opening YouTube and downloading AI models need the internet.
