Your creator profile
Your creator profile is the living portrait byline keeps of how you actually write: your voice, your themes, your audience, and the formats that land. It is the first thing every connected tool reads, so your work shows up sounding like you.
What's in your profile
byline distills your profile into a handful of facets, each a plain description of one part of how you work:
- Topics: the subjects you actually cover.
- Voice: how you sound. Tone, word choice, sentence shape, the phrases that are unmistakably yours.
- Recurring themes: the throughlines and beliefs that keep surfacing across your work.
- Audience: who you are talking to, and what they keep asking for, drawn from the real words in your comments.
- Formats: the structures that work for you, from teardown reels to one-idea newsletters.
- Cadence: your posting rhythm, and how an idea tends to develop over time.
Built from your own work
This is not a style prompt you write and maintain by hand. byline reads everything you have published, plus the private notes you send it, then distills the profile from what is actually there. Nothing is invented.
You can correct it, too. Pin a fact you want it to always honour ("based in Lisbon", "never uses emojis", "my course is Cook Lisbon") and every future read of your profile respects it.
Every read shows its receipts
Each facet is backed by the posts that prove it. When byline says your voice is dry and plainspoken, it can point to the exact pieces that show it. You are never asked to trust a claim about your own voice on faith: the evidence is one click away in your dashboard, so you can keep it or push back.
It refreshes overnight
Your profile is alive. Every night byline re-reads a fresh sample of your work and rebuilds it, so as you publish, your voice on file stays current. Most days there is nothing to do. When you would rather not wait, your dashboard has a refresh that rebuilds it on demand.
Write in your voice
Your profile travels with you into the tools you already write in. Connect byline once:
- Open your tool's Connectors or integrations settings (Claude, ChatGPT, Cursor, and others).
- Paste your byline connection link:
https://byline.fyi/api/mcp
- Sign in with your byline account when it asks. That is the whole setup.
From then on, ask in plain language, for example "write this announcement in my voice." The tool loads your profile first, and the draft comes back sounding like you.
See the difference
The fastest way to feel it is the voice diff: the same prompt answered two ways, one generic, one drawn from your own work. The byline version sounds like you, and it shows the posts it leaned on. That difference is the whole point.
How long until it sounds like you
One dense channel is usually enough for a first profile, and it sharpens every time you add more of your work. You are never left guessing how far along it is: byline tells you how much it has read, so you always know where your profile stands.
