Only New Items | Cross-Run Dedupe Ledger for Any Dataset

Run your scraper on a schedule and get back only what you have never seen before. Name the field that identifies an item, pipe any dataset in, and this actor holds back everything already delivered. Records pass through untouched. The ledger is yours, not a database you rent.

Dataset to filter

datasetId

Optional

This run's scraper output. Pipe any actor's dataset straight in; a picked dataset always wins over the sample records below.

Type:string

Inline records

items

Optional

Records provided inline as a JSON array, for trying the actor out before wiring a scraper up. Ignored when a dataset is picked above.

Type:array

File URL

fileUrl

Optional

URL of a JSON or NDJSON file of records.

Type:string

Key fields

keyFields

Optional

The fields that identify an item, e.g. ["url"] or ["jobId"]. Matching is exact after trimming: no case folding, no fuzzy matching. Leave empty to key on the whole record, which makes any changed field a new item.

Type:array

Ledger capacity

ledgerCapacity

Optional

How many distinct items the ledger is sized for. It stays a few kilobytes either way; going far past this raises the rate at which a new item is mistaken for an old one. The run report always tells you where you stand.

Type:integer

Minimum:1000

Default:100000

Previous memory

memory

Optional

An object beginning with "memoryVersion", copied from the MEMORY record in your last run's key-value store (not your records, those go in the fields above). It holds the ledger of everything already delivered.

Type:object

Memory key-value store

memoryStoreId

Optional

Optional: a key-value store in YOUR account. The actor reads the ledger from it before running and writes the update back after, so scheduled runs chain automatically with nothing to copy by hand.

Type:string

RSS Feed Monitor - New Items Only

technicaldost/rss-feed-monitor

Watch any RSS or Atom feed and get back only the items published since your last run. Remembers what it has already seen, so you never process or pay for the same article twice.

Dataset Deduper | Exact & Fuzzy Dedupe for Any Dataset

broomwagon/dataset-deduper

Collapse duplicates in any dataset, in two passes you control. Exact matching ignores case, punctuation, and word order; an optional fuzzy pass catches the near-duplicates normalization cannot. Every decision is explained in an audit trail, and a cross-run ledger remembers what you already got.

AI Dataset Search

dtrungtin/ai-dataset-search

The actor lets you query any dataset using **plain English** instead of code. Point it at a dataset — for example the output of a scraper run — describe what you're looking for ("videos about race day at the Belgian Grand Prix", "items with more than 100k plays"), and it returns the matching items.

Reddit Brand Mention Monitor & Sentiment Alerts

apt_marble/reddit-brand-mention-monitor-sentiment-alerts

Track every new Reddit post and comment that names your brand or your competitors. Each run returns only mentions you have not seen before — with positive, neutral or negative sentiment, the sentence around the mention and a direct link to reply. Built to run hourly or daily behind an alert.
