UsefulSaathi ek chhota, independent project hai jo Indian parivaron ke roz ke faislon ke liye free online tools banata hai: kaunsa din shubh hai, baby ka naam kis akshar se rakhein, bigha kitna bada hota hai, school kab shuru karein, shaadi mein kitna kharcha aayega, form ke liye photo se PDF kaise banayein, aur bahut kuch. Har tool English, Hindi aur Hinglish teeno mein hai.
Hamare niyam
- Free aur bina login. Har tool bina account ke chalta hai. Site vigyapan (ads) se chalti hai.
- Aapka data aapke paas. Hisaab, PDF, photo aur text aapke apne browser mein process hote hain. Aapki files hamare server par upload nahi hoti.
- Saaf sources. Jahan nateeja kisi niyam ya rate par nirbhar hai (exam ki age limit, GST, HRA, subsidy), wahan page par niyam aur aakhri baar check karne ki tareekh likhi hai.
- Anumaan ko anumaan kehte hain. Shaadi budget, rent vs buy aur bijli bill jaise paise ke tools anumaan dete hain, financial salah nahi, aur aap apne aankde daal sakte hain.
Hamare tools kaise kaam karte hain
- Panchang, Hindu Calendar aur Naam Rashi surya aur chandrama ki sthiti standard khagol formulas (Jean Meeus ki Astronomical Algorithms) aur Lahiri ayanamsa se nikalte hain. Nateeje Swiss Ephemeris se milaaye gaye hain. Tyoharon ki tareekh har tyohar ke paramparik samay ke niyam se nikalti hai.
- Zameen converter har state ke aam taur par maane jaane wale bigha ke maap use karta hai, aur aap apne ilaake ka maap bhi daal sakte hain, kyunki zilon mein farak hota hai.
- Age & Exam Eligibility official notification ki age limit aur cut-off tareekh ke hisaab se chalta hai. Har exam par aakhri check ki tareekh likhi hai; apply karne se pehle nayi notification zaroor dekhein.
- Document Tools, Photo-to-Text aur Study Notes open-source libraries use karte hain jo aapke browser mein hi chalti hain.
- AI Photo Studio image banane ke liye FLUX.1 schnell model (Cloudflare Workers AI par) use karta hai; background hatana aur photo bada karna aapke device par open models (BiRefNet, Swin2SR) se hota hai.
