About Sachilo

Sachilo is an evidence-first fact-checking platform focused on Nepali public-interest journalism. We retrieve, weigh, and quote sources so readers can defend a verdict for themselves, not because an algorithm says so.

01

What this is

You paste a news article or blog URL. Our system reads the article, isolates the factual statements it makes, and searches Nepali primary sources, established Nepali newsrooms, and international agencies for evidence that supports or contradicts each one.

We do not generate opinion. We do not summarize commentary. We have no chat interface. Each verdict is a structured report you can read, audit, or dispute. Every claim ships with its evidence.

02

How verdicts are generated

A five-stage pipeline runs for every submitted URL:

Stage 01
Reading
Fetch the article and extract readable content from the page.
Stage 02
Extracting
Identify atomic factual claims, separating facts from opinion and framing.
Stage 03
Searching
Query trusted sources for evidence that supports or contradicts each claim.
Stage 04
Evaluating
Score each source by tier and determine its stance on the claim.
Stage 05
Preparing
Aggregate evidence into a structured verdict report with evidence strength scoring.
03

How sources are ranked

Every source we retrieve falls into one of four tiers. The tier influences how much weight a piece of evidence carries when we aggregate verdicts.

TierDescriptionExamplesWeight

Domains ending in .gov, .gov.[country code], .go.[country code], or .int are treated as primary unless evidence shows otherwise.gov.np, ec.gov.np, mohp.gov.np, gov.uk, usa.gov, who.int, gov.au, canada.ca, govt.nz, gov.sg, go.jp, gov.kr, gov.cn, gov.in, india.gov.in, europa.eu, un.org1.0

What we will not say

Words carry weight in journalism. We avoid loaded language that asserts intent we cannot prove. The following terms never appear in our verdicts:

fakefalseliehoaxmisinformationdisinformationpropaganda

Instead, every verdict uses exactly one of six labels:

TrueMostly TrueMixtureMostly FalseFalseUnverified
05

How corrections work

Every verdict has a "Request correction" button. Corrections are reviewed by a human editor. When a verdict is changed or retracted, the original is preserved with a strike-through and a dated correction note.
