Brand memory for creators
byline reads what you've already posted and keeps a profile of how you write. Claude or ChatGPT reads it before drafting, so you edit instead of rewrite, and stop pasting your voice doc into every chat.
$0.99 for your first month, no free trial.
Reads
Read-only, never posts. Instagram connects through Instagram's own login, and byline never sees or stores the password. No LinkedIn import yet.
How it works
A style prompt is a guess you retype in every tool. byline gives Claude and ChatGPT one place to read how you write and search what you've already posted.
01
Instagram, YouTube or your site, or forward your newsletter by email. A substantial channel gives the profile a starting point.
02
Your voice, themes, audience and formats, read from your own work. Edit anything it gets wrong.
03
Add byline to Claude or ChatGPT once. Ask it to check your profile and past posts, and the draft starts from how you write.
What you get
Voice profile · example
How you write
The voice card
Your voice, themes, audience and formats in one profile that Claude and ChatGPT can read. Edit it whenever you like.
Ideas
Ranked ideas from your posts and how they performed, each with the posts behind it. More like this, less like this, or snooze.
Your library
Search everything you've posted by what it's about, jump to the original, and remove anything you'd rather byline forgot.
Deep video read
byline picks up the hook, what you said and how it was shot: the talking points a caption leaves out.
What it reads
Connect Instagram, YouTube or a website, or forward your newsletter by email. Your posts come in with their likes, comments and views. The byline quickstart walks through your first connection.
The difference
Left is stock AI. Right is drafted from a creator's own posts.
Excited to share that a new episode is now live. In this conversation we dig into creativity, productivity, and the habits that help you do your best work. There's a lot of valuable insight packed into this one, so be sure to give it a listen. Link in bio. #podcast #newepisode #creativity #productivity
New one's live, and it's the episode I've wanted to make since I started this whole thing. We get into why most productivity advice falls apart the second real life shows up. And what actually holds. No hacks, no five-step morning routine. Just the messy version, told straight. Pour a coffee, it's a long one. Link's where it always is.
Who it is for
byline is brand memory for creators. It reads eligible work you connect and makes a working profile available to supported AI tools.
Each client gets a workspace. byline reads that client's published work and keeps a profile of how they write.
Brand memory per client, read from their Instagram, YouTube videos, website and newsletter, then served to Claude and ChatGPT. No LinkedIn yet.
Built on our own account first
Same Instagram, my voice on every post. Before byline was a product, it was how I wrote my own account. These are the real 30-day numbers, before and after.
Before
295 views a month.
A personal account with almost nobody watching.
The change
Every draft started from my own voice.
I used byline on myself before anyone paid for it: my AI tools read how I write before they drafted, then I edited.
After
4.5M views a month.
3 months later. Same account, my voice on every post, ideas pulled from what already worked.

Your work, your call
byline reads what you've published. It cannot post, reply or change anything on your accounts. Instagram connects through Instagram's own login; byline never sees your password.
Remove one imported post, or disconnect a source and delete everything it brought in. Your work belongs to your workspace, not a public archive.
byline gives your AI tool context. It does not publish. Every draft is yours to check, change or bin before it goes anywhere.

Questions
byline is brand memory for creators. It reads the work you publish on Instagram, YouTube and your website, plus the newsletters and notes you email to it, builds a voice profile from that work, and makes the profile available in Claude and ChatGPT while you draft.
No. byline is a separate service you connect to Claude or ChatGPT, not a GPT or a pasted prompt. Each connected tool reads the same voice profile, which byline builds from your connected channels.
Yes. Custom connectors work on Free, Pro, Max, Team and Enterprise. Free accounts can add one custom connector. On a Team workspace, an Owner or Primary Owner sets them up. Enterprise has separate permissions.
Claude and ChatGPT, through MCP (the Model Context Protocol), an open standard that lets AI tools connect to outside tools and data. You add one link, https://byline.fyi/api/mcp, and sign in once with your byline account in each tool, with no API key. In ChatGPT, custom connections are on Business, Enterprise and Edu; Pro has a narrower read and fetch connection, and Plus doesn't include it.
Your own Instagram Professional account, a public YouTube channel, a website or blog with a public sitemap, and email text sent to your workspace inbox from you or an allowed sender. It also reads available like, comment and view counts, but not the comments themselves, and it doesn't read email attachments. LinkedIn isn't supported yet.
No. byline reads your published work and gives your AI tool your voice profile and searchable past work. You still write, edit and publish in the tools you already use.
It gives each draft a starting point from your own work, not a guarantee. The voice profile is a model-generated interpretation of your processed work, so check it against your posts, correct what misses, and review drafts before you use them.
It stays yours: the originals stay where you published them, and the copy byline keeps is held under your workspace, not in a public archive. You can remove one imported piece, or disconnect a source to remove what it brought in. Some AI processing runs with providers outside the UK, and the privacy notice says where data is processed and stored.
$0.99 for your first month, no free trial. After that, Creator is $29/month and Studio is $99/month, or $261 and $891 a year charged upfront, with no introductory price on annual plans. Creating an account doesn't start reading your full history; that begins after a paid invoice settles.
Connect your channels once. Claude or ChatGPT read how you write before they draft.
