CleverTools.in's answer

1. India-first, not India-as-an-afterthought. Most online tool sites bolt on a generic tax calculator. CleverTools is built around the actual Indian financial year — FY 2025-26 New Regime slabs with the ₹12L Section 87A rebate, post-Budget 2024 capital-gains rates (STCG 20% / LTCG 12.5% / ₹1.25L equity exemption), Section 211 advance-tax instalment schedule with Section 234C interest exposure, and 14 state-wise Professional Tax slabs. Hindi long-tail keywords (gratuity kaise calculate kare, marginal relief kya hai) baked into SEO.

2. Details every other calculator misses.

Surcharge calculator with automatic marginal relief (most tools and even some return-prep software ignore it — costs ₹2-15 lakh near band thresholds) Leave Encashment with the full Section 10(10AA) four-limit rule AND the lifetime ₹25L cap tracked across employers Gratuity with both formulas (15÷26 covered / 15÷30 not-covered) + 5-year-OR-4y240d eligibility (Madras HC Mettur Beardsell ruling) Salary Slip with the statutory ₹1,800 PF cap (12% × ₹15,000 ceiling) auto-applied 3. 100% browser-based — files never leave your device. No server uploads. Your salary, PAN, GSTIN, bank account, PDFs — all processed locally with pdf-lib, jsPDF, pdfjs-dist. Works offline after first load.

1. Tool depth, not link-farm breadth. 80+ tools, but each ships with 4-6 features, 3-4 how-it-works steps, 4-8 FAQs (which generate Google FAQ rich snippets), and 30+ targeted keywords. Compare to most competitors where the "calculator" is a single input + result.

2. Receipt/document generators that actually match Indian payroll/compliance formats.

Salary Slip with 3 templates (Classic Grid / Modern / Minimal), live PDF preview, full WD/WO/PH/PD/CL/PL/SL/LWP working-days breakdown, Actual + Payable columns with auto-prorate on LWP Rent Receipt with sequential numbering, payment-mode line, revenue-stamp prompt above ₹5,000, mandatory landlord-PAN warning above ₹1L/year GST Invoice with auto CGST+SGST vs IGST routing, 5 tax slabs, reverse charge, e-way bill, HSN autocomplete 6. No signup wall, no rate limits, no watermarks. Free tools that stay free — even with file uploads.

1. Modern stack & performance. Next.js 16 + Turbopack, Tailwind 4, strict TypeScript, full dark-mode parity, 156 prerendered pages, dynamic imports per tool so each route ships only what it needs.

2. Honest math, transparent reasoning. Calculator outputs explain why — which limit kicked in, which slab applies, why marginal relief was/wasn't triggered. Not a black box.

Three reasons:

Accuracy on the details that cost real money. Marginal relief, the ₹1,800 statutory PF cap, the four-limit rule for leave encashment, the 4y-240d gratuity eligibility ruling — most calculators miss these and quietly cost users ₹2–15 lakh. CleverTools applies them automatically and explains which limit kicked in. Privacy by architecture. Your PAN, GSTIN, salary, bank account, PDFs — they are processed in your browser using pdf-lib and jsPDF. Nothing is uploaded. Works offline after the first visit. Free, fast, no friction. 80+ tools, no login wall, no rate limits, no watermarks on PDFs. Each tool is a single static page — no spinning loaders, no "buy premium" interstitials.

CleverTools.in's answer

CleverTools was started by Milan Bagiya out of frustration with the state of online Indian tax calculators — most were either ad-laden link farms with wrong formulas, or behind ₹999/month paywalls. The premise was simple: build a focused, free, India-first tool suite where the math actually reflects current law (post-Budget 2024 reforms, latest CBDT notifications), where files never leave the user's browser, and where every calculator explains why its answer is what it is. It started with PDF and image utilities; the financial calculator suite (Income Tax, HRA, Gratuity, Capital Gains, Advance Tax, Surcharge, Professional Tax, Leave Encashment) is the current focus — each one researched against actual sections of the Income-tax Act and Indian state-level rules.

StitchMath's answer:

StitchMath was born from the frustration of "yarn chicken" and poorly fitting hand-knits. We set out to build a precision dev-tool for makers, applying data-driven logic to traditional crafting.
