How We Build and Verify Every Tool
Transparency is not optional on a site that handles health and finance content. This page explains exactly how every tool on YourToolsBase is sourced, built, reviewed, and maintained.
Our Core Commitments
- Every formula comes from a named, publicly accessible authoritative source
- No tool claims to provide medical diagnosis, treatment, or personalised financial advice
- All health and finance tools carry an explicit disclaimer
- Content is AI-assisted and editorially reviewed before publication
- Sources are displayed on every tool page — users can verify everything independently
- Errors reported by users are investigated and corrected promptly
Our Six-Step Editorial Process
1. Formula & Data Sourcing
Every tool starts with a primary authoritative source. We do not invent formulas — we locate the official definition from a recognised body (e.g. CDC, NIH, IRS, NIST, W3C) and implement exactly that. The source is recorded and displayed on the tool page in the Sources strip so users can verify it independently.
2. Tool Implementation
Tools are built as browser-based JavaScript components. All calculations run locally on the user's device — no inputs are transmitted to our servers. We test each tool against manually calculated results and, where available, against official reference values published by the source authority.
3. Content Drafting
Supporting content (What Is, How To Use, Formula Explained, Case Study, FAQs) is drafted using AI-assisted writing. The AI is given the exact formula, the primary source, and strict instructions to cite only real, verifiable data. No fabricated statistics or invented studies are permitted.
4. Editorial Review
Every page is reviewed by our founder and editor, Muhammad Shahbaz Siddiqui, before publication. The review checks: (a) formula accuracy against the source, (b) that all numbers in examples are realistic, (c) that health and finance pages carry the required disclaimer, and (d) that no unsupported medical or financial claims are made.
5. YMYL Compliance Check
Health and finance tools undergo an additional compliance check before publishing. We verify the disclaimer is present and accurate, that the tool does not claim to diagnose, treat, or provide personalised financial advice, and that the authoritative source cited is current. Tools that cannot meet this standard are not published.
6. Ongoing Updates
We monitor source authorities for changes to guidelines (e.g. IRS tax bracket updates, CDC BMI recalibrations). When an authoritative source updates its data, we update the tool and its content within 30 days. The 'Last reviewed' date on each tool page reflects the most recent editorial check.
Authoritative Sources by Category
The following organisations are our primary reference authorities. When their guidelines change, we update our tools accordingly.
Health & Medical Tools
Finance & Tax Tools
Math & Science Tools
Unit Converters

Health & Finance: Extra Safeguards
Tools in the health and finance categories are classified as YMYL (Your Money or Your Life) content by Google — meaning errors could have real-world consequences for users. We apply stricter editorial standards to these tools:
- •Explicit disclaimer on every health and finance tool page
- •Formulas cross-referenced against official government or clinical guidelines
- •No personalised advice — results are population-level estimates only
- •Clear recommendation to consult a qualified professional for decisions
- •Review cycle of 12 months or sooner when source guidelines change

Who Reviews This Content
All content on YourToolsBase is reviewed by Muhammad Shahbaz Siddiqui, founder and editor. His background spans SEO, content strategy, web development, and digital marketing — giving him the editorial judgement to assess whether tool content is accurate, clear, and appropriately disclaimed.
For domain-specific accuracy (e.g. a specific clinical formula or tax rule), we cross-reference the primary government or clinical source directly and cite it on the page. The cited source — not any individual reviewer — is the authority for that content.
