Will it post every pull request?

No. Housekeeping changes are skipped and every note stays switched off until you turn it on. Nothing from GitHub reaches a post before that.

What about security fixes?

Notes on security or privacy work describe the benefit at a high level and never the weakness that was fixed. You still read each one first.

I don't write the code. Is this for me?

Yes. Pick founder, then tell Prospel you run the business side. You'll get questions about decisions, customers and lessons, and GitHub stays optional.

Will it make up my numbers?

No. Revenue, user counts and other figures only appear when you've given them. Posts with result figures Prospel can't match to your facts are rewritten without them or dropped.

Can I post about more than one product?

Yes. Connect more than one GitHub account or organisation, and Prospel names the product each note is about from the products in your persona.

Prospel for founders

Your commits already tell the story. Prospel writes it up.

Connect GitHub and every merged pull request becomes a plain-English update note. Prospel drafts X and LinkedIn posts from those notes in your voice, so building in public stops being a second job.

#214 Stream CSV exports instead of building them in memory

Update note, in plain English

Big exports now start downloading the moment you click, even at 100,000 rows. Before, they could time out.

Drafted in your voice

Draft for X

Shipped in Acme: exports start downloading the moment you click.

No more waiting on a spinner for a big CSV. I rebuilt it to stream rows as they're read.

Sound familiar?

You ship every week and post once a month.: Your merged work becomes a steady stream of drafts, so the posting keeps pace with the building.
Changelogs read like commit messages.: Notes are written for users, not engineers: what it does now and why it matters.
AI tools invent traction you don't have.: Prospel never makes up users, revenue or features. Your numbers are used as you give them, or not at all.

GitHub to posts

From merged pull request to post, without the jargon

Prospel reads the title and description of each merged pull request on the repos you choose and writes a short note on what changed for the people who use it. You switch on the notes worth sharing, and drafts follow.

Step 1
Connect the repos you pick
Read-only GitHub App access, only to the repos you choose. Anything you leave out stays invisible.
Step 2
Read the update notes
Dependency bumps, tests and refactors are skipped. Each note arrives switched off until you've read it.
Step 3
Get drafts that sound like you
Shipped notes become build updates, lessons and decisions in your voice, each one scored for its platform.

Sounds like you. Never makes things up about you.

Opinions, lessons, tips, frameworks and motivation are most of what good accounts post, and Prospel writes plenty of them. They don't need to have happened. Facts about you do.

What you'll get

What shipped and why it matters
Lessons from what broke
Decisions, including the ones you reversed
Opinions on your market
Plain-English product explainers

What Prospel never invents

Results, revenue or figures you didn't give it
Client names or client results without your permission
Product features you don't have
Promises or guarantees to your readers
Things that happened to you that you never mentioned

Checked in code on every automatic draft. A draft that slips is rewritten once without the claim, or dropped.

How it works

1
Show Prospel how you write
Add a few of your best posts and say who you write for. Prospel builds a style guide you can edit, with a separate voice for X and LinkedIn if you want one.
2
Connect GitHub
Pick the repos. Merged pull requests sync daily, or whenever you press Sync.
3
Approve, and it publishes
Drafts land in your queue in your voice. Edit anything, approve what you like, and Prospel posts to X and LinkedIn at the times you set.

3 X posts and 1 LinkedIn post a day, leading with X. Build-in-public audiences gather on X; LinkedIn is where buyers read the weekly roundup.

Also useful for founders

Build-in-public series: Numbered episodes (S1 E1, E2...) posted in order, at the same time each day or every few days.
X Articles: Long-form launch write-ups on X, drafted from your notes. You read every article before it goes out.
API and MCP: Connect Claude Code, Cursor or your own scripts to your voice, drafts and queue.
Several X accounts: Run a personal and a product account from one place on Authority or Mogul.

Common questions

No. The GitHub App asks for read-only access to pull requests and repository metadata on the repos you choose. Each note is written from the pull request's title and description.

Ship it, then say so.

Connect GitHub on day one and see your first update notes before the trial ends. Cancel before day 5 and you won't be charged.
