Over the past few months I have been shipping small, single-purpose web tools. Each one is built with AI-assisted coding (Next.js + Cloudflare Pages) and designed to do exactly one thing. No sign-up, no upload, everything runs in your browser.
Here is the full list in case any of them save you a few minutes.
File and image
- LivePhotoKit converts Apple HEIC images and Live Photos (.livp) to JPG, PNG, WebP or PDF, or extracts the MP4, all locally in your browser.
- iWorkViewer opens .pages, .numbers and .key files on Windows or Android without a Mac, and exports them to PDF.
Calculators
- FreeTDEE is a TDEE, BMR, calorie and macro calculator.
- BabyPercent is a baby growth percentile calculator (WHO/CDC) for ages 0 to 24 months.
Planning
- PlantingCalendar gives vegetable planting dates by USDA hardiness zone.
- ZonePlan is a time zone meeting planner and live world clock.
Everyday
- InvoicePad is a free invoice generator for freelancers, with no sign-up.
- PupVax is a dog vaccine tracker with schedules and reminders.
The stack
Every site is Next.js with static export, deployed on Cloudflare Pages. AI handled most of the coding while I focused on picking the problem, the SEO and the UX. Each tool is intentionally tiny and privacy-first: no accounts, no uploads, and processing happens client-side.
I would love feedback, especially on which ones are genuinely useful versus which are solving a non-problem. What tiny tool do you keep wishing existed?
