Been hoping someone would build this.
The annoying part of cross-posting isn’t resizing content — it’s rewriting the same idea 4 different ways for LinkedIn, X, IG, TikTok, etc. That’s the part that eats hours every week.
A lot of AI social tools still feel pretty shallow to me. Same caption rewritten slightly differently, or decent visuals with generic copy.
What caught my attention here:
different creative directions per platform instead of just reformatting
tying outputs back to source material
carousel support actually built into the workflow
If this consistently saves me from the “adapt this everywhere” cycle, that’s a real workflow upgrade, not just another AI wrapper.
Going to test it this week.

hey everyone, it's Nathan (again)
kraft is our long-form writer. it's the third tool in layerproof, after matte (social post) and chromo (slides).
people have a real idea worth sharing, they sit down to write it up, and the blank page wins. they either post nothing, or let an AI generate something generic that doesn't sound like them.
kraft is built for that messy middle. drop in your scattered notes, pick an angle and tone, set a length. it drafts a full page in your voice. when you're done, it can repurpose the piece into platform-ready posts.
a few things we're particularly proud of:
the tone slider actually changes the writing, not just swap vocabulary
the repurpose flow respects platform conventions (linkedin reads like linkedin, x reads like x)
you can switch themes to match your brand without redoing layout
we'd love feedback. especially curious whether kraft holds your voice through the repurpose step, since that's the part we wrestled with most.

Hey Product Hunt! 👋
I do marketing at LayerProof. I write a lot on LinkedIn and Medium, and Kraft is honestly the tool I wished I had for a while.
My problem was simple: I had the data and the ideas, but making them look good meant jumping between a writing tool, a chart maker, and design tools. By the time it was done, I was exhausted.
Kraft lets me do it all in one place:
Read my source docs and write with full context. No tab-switching, and I control every word
Turn raw data into interactive charts right inside the post - actual charts my readers can explore
Mix visuals and text naturally like the way ideas actually flow when you’re explaining something
A Medium article that used to take me an afternoon now takes under an hour, and looks better. It's for writers that want to write deeper and have better control while riding the power of AI.

🤔 I write a lot of marketing content and honestly, most AI tools make me feel like an editor, now a writer. I spend more time fixing the AI's output than I would have spent writing from scratch.
Kraft flipped that for me. I set the tone and audience upfront, start writing and Kraft fills in around me - structure, flow, transitions. When a paragraph isn't landing, I highlight it and hit rewrite. It feel like pair-writing with someone who really understands and gets my voice.
The best part? I upload my briefs and source docs, Kraft reads them so I don't have to keep switching tabs to pull in references. Everything I need is right there while I write!

It's Bryan here!
I’m a numbers person pretending to be a words person. My content always starts with data - campaign results, market stats, user trends, but turning that into something people actually want to read? That used to be a whole production. So we made @LayerProof Kraft.
Kraft’s interactive charts changed everything for me. I paste in raw data, play around with data directly in chats and drafts, and finally get charts I can embed directly in my post.
That one feature turned my data-heavy LinkedIn posts from “informative but skippable” to something people actually engage with.
Besides interactive charts, my teammates also enjoy other features, such as customize tones, parallel pdf reader, and visual generations.
How about you?

Love the “messy middle” positioning. That’s exactly where most AI writing tools fail: they either stay too blank or jump directly to generic content. The hard part is not generating text, it’s preserving the original thinking and voice while making it publishable. How you measure whether Kraft actually kept the user’s voice after repurposing?
