Small, sharp tools for people who run social accounts for a living.
Kadenzo is a slow-growing collection of free utilities for social media managers, creators, and agencies. Everything runs in your browser on your own numbers — no login, no scraped data, no “start your free trial” wall between you and the answer.
Tools
All tools →Engagement Rate Calculator
Platform-native metrics, the right denominator, multi-post averaging — and a methodology line you can paste into the report.
UTM Builder
One link or a whole campaign set — consistent vocabulary, GA4 channel preview, CSV export.
Thread Splitter
Sentence-aware splits with the character math each platform actually uses — and posts you can edit before copying.
Content Calendar Template
A dated calendar for your channels and posting days — every slot pre-filled with an idea, hook starter, and format.
LinkedIn PDF Carousel Maker
Paste a long draft, get editable slides, a cover, and your own photos — a square or 4:5 PDF built entirely in your browser.
Character Counter
One paste, every platform: real counting rules, real limits, and the fold points where feeds truncate your post.
How this site works
- Your input only. Every tool works on numbers you type or files you choose — nothing here fetches, scrapes, or monitors other accounts.
- One good page per tool. Each tool ships with the explanation, examples, and benchmarks needed to actually use the output — not a thin widget farm.
- Built slowly.New tools are added when they’re genuinely useful, not to fill a sitemap.
