I built DosCifras because the tax calculators I found were either generic — one rate for everyone — or made you sign up for something that should take three seconds. Across the Spanish-speaking world, every country has its own rules: VAT works differently in Mexico than in Chile, and Spain's income tax looks like no one else's. I wanted a tool that respected that: your country's calculator, with your country's official rules, free and friction-free. It currently covers Spain, Mexico, Argentina, Colombia and Chile, and keeps growing.

@lijiayouyj I really appreciate it. Thanks for your feedback

"Stop translating. Start creating."

Hey! 👋 I built InfluTools after noticing something obvious once I looked for it: almost every tool for content creators — character counters, engagement calculators, hashtag generators — is built for English speakers. If you search for the same thing in Spanish, you mostly get translated interfaces bolted onto tools that were never designed with Spanish-speaking creators in mind.

InfluTools is my attempt to fix that for the 400M+ Spanish speakers worldwide: three free, no-signup tools built natively in Spanish — a character counter with exact limits per platform, an engagement rate calculator with benchmarks, and a hashtag generator with real Spanish hashtags by niche (not translations).

It's a side project, still early, and I'd genuinely love feedback — especially from anyone who works with Spanish-speaking creators or has hit the same "everything's in English" wall. 🙌
