One idea in.
A little you on every app.

Bring a thought, a video, a half-finished blog post. Quillcaster turns it into posts that fit every platform, publishes them for you, and figures out what your people love. You just say the word.

We ditched Redis for Postgres and pg-boss. One less thing to babysit. Here’s why it was worth it.

three easy steps

You do the fun part. We do the rest.

1Toss in an idea

A note, a video, a link, a voice memo. However it falls out of your head. No format required.

2Get a little you

We rewrite it to fit each place. A thread here, a carousel there, always sounding like you, never a robot.

3We post & learn

We publish at the right time, notice what people liked, and leave next week half-drafted and ready for a yes.

say hi to the team

Two little helpers. One tidy feed.

Knackthe ideas one

Knack takes your one idea and reshapes it for every app: a thread here, a carousel there, a hook-first clip over there. It just knows the vibe.

Nudgethe doer

Nudge posts everything at the right time, keeps an eye on what lands, and gives you a friendly nudge when next week’s already drafted and waiting.

the good stuff

Not another scheduler.

Anyone can queue a post. These are the bits that actually save your week.

Native, never copy-paste
Every app gets its own version in its own language, never one caption pasted eight times.
Chops up long videos
One long video becomes a stack of ready-to-post clips, auto-captioned and reframed to fit.
Sounds just like you
It learns your voice from your old posts, so everything reads like you wrote it. No beige.
Drafts your whole week
It reads what’s working and hands you next week half-done. You just approve or tweak.
Loves the little apps
Bluesky, Mastodon, and Farcaster get the same love as the big ones. The others skip them.
Feed it anything
Point it at a blog post, a YouTube video, or a podcast, and out comes a whole week of posts.
one video, lots of clips

Drop a long video. Get a pile of clips.

Knack finds the good moments, cuts them, writes the captions, and reshapes each one to fit where it is going. A whole week of video from a single upload.

good questions

Bits you might be wondering.

What is Quillcaster, in one breath?
You bring one idea; Quillcaster turns it into posts that fit every platform natively, publishes them at the right time, and learns what your audience responds to. One idea in, a little you on every app.
Is this just an AI caption button?
No. It writes a genuinely different post for each app in your voice: a thread here, a carousel script there, a professional reframe for LinkedIn, a hook-first outline for a short. Then it schedules, publishes, and learns what works. The scheduling is the boring part, not the point.
Will everything sound like a robot?
It learns your voice from your own posts, so it reads like you on a good day. Every workspace gets its own brand voice, and you can always edit before anything goes out.
Do I have to approve every post?
You are in charge. Review it, tweak it, or just hit go. Once you trust a channel you can let it run, and the approval workflow is there for teams and agencies that need a second set of eyes.
Which apps can I post to right now?
Three are open and ready today: Bluesky, Mastodon, and Farcaster — connect your account and post. Five more are built and going through each platform’s app review: Instagram, Threads, Facebook, LinkedIn, and Pinterest. Others (Telegram, Discord, TikTok, YouTube, Reddit, and more) are on the roadmap. Official APIs only, no sketchy workarounds.
Can it turn my long video into clips?
Yes. Drop one long video and it finds the good moments, cuts them, writes the captions, and reshapes each clip to fit where it is going: 9:16 for vertical, 1:1 for square, 16:9 for landscape. A whole week of video from a single upload.
How much does it cost?
Free to start while we are in early access, and no card is needed to begin. Paid plans come later, priced per seat or per workspace.
psst, got an idea?

That’s the hard part done. We’ll take it from here.
