Why standard spreadsheets and manual sorting fail on Lead Judge
The Latency & Fatigue Bottleneck
When operations or revenue teams download raw data dumps with 2,000 to 25,000 rows, team members spend an average of 4.5 hours manually skimming rows, applying ad-hoc Excel autofilters, and deleting records. Human decision fatigue sets in after only 200 rows, leading to false positives and accidental deletion of valuable accounts.
Downstream API & Credit Waste
Uploading unfiltered CSVs directly into downstream enrichment platforms (such as Clay, ZoomInfo, or email verification tools) burns credits on contacts you will never reach. At an average of $0.15–$0.40 per enrichment lookup, running a dirty list wastes hundreds of dollars in under five minutes.
RFC 4180 Ingestion
Streams raw CSV bytes into an in-browser Web Worker, automatically removing UTF-8 BOM signatures and preserving multiline quotes.
Natural Language Compile
Gemini Flash compiles your plain-English prompt into structured rule trees, exclusion lists, and weighted signal dictionaries.

Frequently Asked Questions
Does my raw lead list get uploaded to a server?
No. Your CSV is parsed locally in your browser. MiniJudge only transmits the necessary text fields for active judgement chunks.
Can I customize the criteria?
Yes. Write whatever nuance matters to you in plain English — industry, headcount, tech stack, geography, or exclusions.
How many rows can I run for free?
The first 100 rows are always free, with full previews so you can verify our understanding before running your entire dataset.
