Watch it see

One signal in, one published post out

No editorial calendar, no blank page, no six-week content sprint. Connect a source and Letterseer handles the watching, the writing, and, if you want, the publishing, end to end.

  1. 01

    It keeps watch.

    Your repos, Notion, the specs you build on, the news and the law: polled around the clock, every 30 minutes for code, daily for regulation.

  2. 02

    It ignores the noise.

    Every change is scored against your positioning. Dependency bumps, typo fixes and off-topic news are dismissed quietly.

  3. 03

    It catches the signal.

    The change that matters clears the bar, with the topics it matched and the reason, so you can see why it fired.

  4. 04

    It writes the story.

    A sharp headline and a full on-brand draft, grounded in the real change. Suggest waits for your nod; Autopilot publishes.

AutopilotPublished to acme.com/blog · 620 words

It starts fresh, with no back-filling of old history. It only writes about what happens once it’s watching.

Six signal sources

Pick a signal. Watch it become a story.

Two kinds of change never stop moving: what happens in your own work, and what moves in your market. Letterseer watches both, and turns the moments that matter into finished posts.

Who it’s for

Built for teams that move faster than their content calendar

Dev tools & OSS teams who ship daily and never write it up.

API-first products building on fast-moving specs and standards.

Teams that want the first take on the news and regulation their market is watching.

Lean marketing teams who want one signal in and one published post out.

Why Letterseer

Your product-market-fit keeps changing. Content should adapt.

Nothing worth writing about gets past the watcher that sees every signal, and turns it into the story.

No blank page

Every piece starts from a real event, not a prompt. The change is the brief.

Never blinks

Around-the-clock watch that never misses a ship, a release, or a headline.

Sounds like you

On-brand voice, grounded in the actual change. It reads like your team wrote it.

Zero busywork

From signal to published in a single hop. No calendar, no drafts to chase.

FAQ

The questions you’d ask first

Does it write the whole article or just an idea?
A full draft. Run it in Suggest mode (you approve the headline first) or Autopilot, where it writes and publishes on its own.
Will it sound like AI?
Letterseer is built on Letterstory’s writing kernels to create beautiful, well-researched content that ranks and performs.
Do I need to expose a private repo?
No. Public repos work with zero setup; private repos connect with a token.
How often does it check?
Continuously, tuned per source, from every 30 minutes for code to daily for regulation.
Can I control what it flags?
Yes. Filter by branch, label, title, keyword, or jurisdiction so only what matters becomes a post.
