Meet InkFlow — turn any font into an animated write-on
Type a word, pick a font, and watch it get written on-screen, letter by letter — then download it as a Lottie, video, or GIF and drop it into your project. Free, in-browser, and nothing you type ever leaves your device.
Animated text that writes itself onto the screen is everywhere now — in app intros, logo reveals, title cards, Instagram stories, YouTube openers. It looks great. It's also usually a pain to make: open a heavy motion-design app, hand-trace every letter with the pen tool, tweak the timing, render, repeat. For a single word.
We wanted that effect without any of that ceremony. So we built InkFlow — the newest addition to the Sadapanna lineup, and the first one you can use right now, no download, no sign-up.
What it does
InkFlow takes two things — your text and a font — and produces a smooth animation of that text being drawn on, stroke by stroke. You control how it moves; it hands you a ready-to-use file at the end. That's the whole idea.
There are two ways it can draw your letters:
Outline + Fill
The letter's outline is traced by a moving stroke, then the fill fades in behind it. Works with any font you
upload — .ttf, .otf, or .woff.
Handwriting
True single-line pen strokes in real writing order, using classic engraving fonts. Letters draw one after another, like an actual hand moving across the page.
You're in control of the feel
The default looks good, but the fun is in the dials. InkFlow gives you the knobs that normally live deep inside a motion-graphics timeline:
- Easing — 14 presets, from a crisp snap to a slow, lazy glide.
- Timing — set how long each letter takes, and how much one letter overlaps the next (0 to 120%), so the writing can feel measured or rushed.
- Look — font size, stroke width, stroke and fill colors, when the fill starts fading in, and a transparent or solid background.
- Playback — an end-hold pause, frame rate, and a built-in player with play, pause, scrub, loop, and preview speed.
The goal was simple: get from "I have a word" to "I have a video of that word being written" in under a minute — without opening anything you'd have to learn first.
Export it your way
An animation is only useful if it fits where you're taking it. InkFlow encodes everything right in the browser and lets you leave with whichever format your project needs:
Lottie JSON
Tiny, editable in After Effects, and plays natively on web, iOS, and Android.
MP4
Encoded in-browser at 0.5×, 1×, or 2× resolution — ready for any video edit.
GIF
The universal drop-anywhere format, for chats, docs, and quick shares.
WebM
Keeps a transparent background — perfect for overlaying on top of other footage.
Private by design
This is the part we care about most, and it's the part that's easy to miss. InkFlow has no backend. Your text, the fonts you upload, every frame it renders — all of it stays on your machine. Font parsing, animation, and video encoding happen locally in your browser.
Nothing is uploaded, anywhere. Upload your brand's private font without a second thought — it never touches a server, because there isn't one.
That's the same rule we hold every Sadapanna product to: store your data on your device wherever possible, collect only what's genuinely needed, and never sell it. A free tool that quietly harvested your fonts and text would fail that test on the first line.
Who it's for
If you make things — motion designers, indie app builders, content creators, marketers, or someone who just wants a nice animated title for a video — InkFlow is meant to save you the tedious middle part. Bring a word and a font; leave with a finished animation.
InkFlow is one of a handful of things we're building at Sadapanna, and the first we've been able to just hand people, no waiting. We'd love to hear what you make with it — reply anytime at hello@sadapanna.com.
