**Mayd-It · Creator publishing**

Follow known creators on Japan’s note.com community without maintaining your own RSS collector. Bring publisher headlines, opening excerpts and source links into a creator watchlist or campaign report.

**Source scope:** Public creator RSS only. No login, API key or proxy; article pages, paid material, profiles, comments and follower lists are not opened.

## What you get

- Attributed headlines and publisher excerpts with stable note IDs.
- Literal title or excerpt mentions for a defined creator watchlist.
- Saved headline and excerpt comparisons with previous values.

## Try a small run

Copy this exact input into the Actor’s JSON input editor, then run it.

```json
{
  "creators": [
    "info",
    "note_ir"
  ],
  "maxItemsPerFeed": 10,
  "maxResults": 20
}
```

This example selects up to ten entries each from the official `info` and `note_ir` feeds. `{}` uses the same demonstration creators. Supply exact handles in `creators` to replace them with your own watchlist. Review the dataset and `SUMMARY` after the run.


## Understand your run

Open **Run report** in the run’s Output tab for saved-record counts, reported source issues and limits, and suggested next steps. Use **CSV export** to take the saved results into a spreadsheet. The existing JSON results and detailed machine-readable summary remain available.

The report reflects this run’s recorded coverage. A successful run or a saved result does not establish that every possible source record was collected.

## Cost

**FREE / BRONZE: $0.002 per saved observation ($2 per 1,000).** SILVER: $1.60 per 1,000. GOLD / PLATINUM / DIAMOND: $1.20 per 1,000.

The Actor Start event is **$0.00005 per charged start unit**, with one unit per GB of Actor memory and a minimum of one. The Pricing tab shows the rate for your Apify tier. New, changed and ordinarily saved unchanged observations use the same result rate. Skipped unchanged rows, rejected events, duplicates and error diagnostics are not paid result rows. Use `onlyChanges` for repeated monitoring after establishing history.

## A real result

Selected fields from a recorded run on **10 October 2026**. This is an example of the output shape; source content and counters can change.

```json
{
  "noteId": "n7ce9240358d7",
  "title": "仲間と力を合わせて、乗り越えたことは？「#チームだからできたこと」で投稿を募集します。",
  "sourceHandle": "info",
  "creatorName": "note公式",
  "publishedAt": "2026-10-09T02:00:00.000Z",
  "sourceUrl": "https://note.com/info/n/n7ce9240358d7",
  "comparisonStatus": "not_requested"
}
```

The complete row also contains the publisher’s opening excerpt. No translation, generated summary or sentiment is added.

## More examples

### Watch note editorial community posts

Read the editorial community feed through the same bounded RSS workflow.

```json
{
  "creators": [
    "notemag"
  ],
  "maxItemsPerFeed": 10,
  "maxResults": 10
}
```

### Compare saved note investor announcements

Establish history for the investor-announcement feed. Repeat sequentially with `onlyChanges: true` to save only new or changed observations.

```json
{
  "creators": [
    "note_ir"
  ],
  "maxItemsPerFeed": 10,
  "maxResults": 100,
  "comparePrevious": true,
  "snapshotName": "example-note-ir"
}
```

## Input reference

| Field | Meaning |
|---|---|
| creators | Up to 20 exact note.com handles; URLs are not accepted. |
| maxItemsPerFeed | First entries in each feed’s supplied order, before keywords or comparison; default 10, maximum 25. |
| keywords | Up to 20 literal case-insensitive substrings. Any matching title or returned excerpt qualifies. |
| maxResults | Confirmed saved observations; default 20, maximum 500. Skipped unchanged rows do not consume this cap. |
| comparePrevious | Compare against saved observations; default false. |
| onlyChanges | Implies comparison and skips unchanged observations; default false. |
| snapshotName | Named history namespace, 1–40 letters, digits, underscores or hyphens. |
| maxRunSeconds | Default 240, minimum 30, maximum 3600; also bounded by the platform deadline minus 25 seconds. |

## Output reference

Each real observation includes `noteId`, `title`, `excerpt`, `excerptTruncated`, `sourceHandle`, `creatorName`, `publishedAt`, `sourceUrl`, `feedUrls`, `matchedKeywords` and `observedAt`. The note ID comes from the canonical note URL. Publisher display names can be empty if omitted in a source feed. A `thumbnailUrl` is included only when the feed supplies a usable HTTPS image URL; the image itself is never fetched.

Descriptions are publisher excerpts normalized to plain text. Excerpts are capped at 4,000 characters and `excerptTruncated` reports that cap. The Actor does not generate summaries, translate text, infer sentiment or fetch full article content. Keyword matching uses only the returned title and excerpt.

Comparison output is `comparisonStatus` (`not_requested`, `new`, `changed` or `unchanged`), `changedFields`, `previous` and `previousObservedAt`. Watched fields are title, excerpt, truncation flag, publisher date, creator handle and creator display name. Thumbnail URLs, feed membership, matched keywords and observation time are excluded from comparison.

## Saved history and repeat runs

The first comparison run emits initial observations as `new`. Repeat the same bounded source window and `snapshotName` with `onlyChanges: true` to export only new or changed observations. An unchanged repeat legitimately saves zero rows. History records the last saved observation, so unchanged skipped runs do not advance `previousObservedAt`.

Named stores use `maydit-note-feed-<snapshotName>`. History is keyed by post identity within that namespace. Only confirmed saved rows update it. A rejected spending-limit write, filtered entry or unsaved result cannot be marked seen. Existing records are retained when an entry disappears from the recent window; no deletion is inferred.

Run a snapshot namespace sequentially. A reread catches some overlapping writes, but it is not an atomic lock. Use different names for independent workflows. Invalid saved history is reported as an error and preserved; select a new name to start again.

## Coverage and limitations

note’s documented creator RSS contains the latest 25 entries in publication-date order. This version accepts `note.com` creator handles only, not magazine feeds or custom-domain note pro feeds.

An edit is detected only while the post is visible in the selected feed window. A publication date is the source’s publication date, not an edit timestamp. This Actor does not expose engagement counts, follower counts, comments, ranking scores or historical backfill. Feeds can lag or change between requests.

Overlapping feeds are deduplicated by post identity and their `feedUrls` are retained. If the same post has conflicting fields in two responses, the first observation is retained and the conflict is recorded in SUMMARY. Treat that run as partial.

SUMMARY records actual saved and observed counts, per-feed available/selected entries, filter and unchanged skips, failed sources, sources not reached and deadline or spending stops. A selected result/window cap is scope, not an operational failure. Partial runs can contain useful paid observations. All-source failures with no usable output fail rather than producing fake error rows.

Requests respect robots.txt, validate public network destinations, reject redirects and bound response size and retry delays. Robots restrictions or upstream errors are reported. There is no fallback through private APIs or alternate anti-bot routes.

## Source and reuse

The platform documents its feeds here: [official RSS instructions](https://www.help-note.com/hc/ja/articles/4402395202841). This Actor is independent of the platform. Public syndication does not transfer copyright; retain the publisher link and respect the source’s terms when reusing excerpts.

## Development

Node 20.19 or newer; exact `apify` 3.7.2 and `cheerio` 1.1.2, with `basic-ftp` overridden to 6.2.2. Run `npm ci --ignore-scripts --omit=optional`, then `npm test` or `npm start`. Use isolated `CRAWLEE_STORAGE_DIR` directories for local runs. The Docker image uses Node 20. No downloaded code or post content is executed.

## Troubleshooting and support

| If you see… | Check this |
| --- | --- |
| A keyword returns no rows | Keywords match literal substrings in the selected entries’ returned titles and excerpts. Increase the selected window within its limit or use a more specific creator list. |
| An older post is missing | Creator RSS exposes the latest 25 entries. This Actor does not backfill an archive. |
| A repeat saves zero rows | An unchanged `onlyChanges` run can be valid. Check `SUMMARY` for source failures or an incomplete run. |

For help, open an Actor issue or contact **bmay@mayd-it.com**. Include the run ID, selected sources and the relevant `SUMMARY` message. Do not send credentials. This Actor is independent of the platform.
