Features
Everything between “merged” and “announced”
Signal watches your repos and trackers, drafts the story, and delivers it everywhere your customers listen.
Release notes, drafted for you
Merge a pull request and Signal writes the customer-facing version — plain language, grouped by feature, tone-matched to your brand. You approve, it publishes. A week of shipping becomes a story in one click.
A changelog worth linking to
A fast, hosted, branded changelog on your own domain — custom colors, your logo, clean URLs, RSS built in. Every release gets a permalink your team can drop into support replies and sales threads.
What's New, inside your app
One script tag adds an in-app widget that badges unseen updates. Dark mode, your fonts, zero iframe jank.
Feedback where it lands
Reactions, comments, and feature requests on every update — routed back to your tracker with full context.
Delivered everywhere
Email digests, Slack posts, and RSS go out with every release — each channel on its own schedule.
How it works
From merge to megaphone in three steps
No new workflow to learn — Signal sits at the end of the one you already have.
Connect your sources
Authorize GitHub, Linear, or Jira in two clicks. Signal starts listening to merges, closed issues, and shipped tickets immediately.
Review the draft
Each release arrives pre-written in plain customer language. Edit anything, drop what's internal, and match your voice once — Signal remembers.
Publish everywhere
One click sends it to your hosted changelog, the in-app widget, email, Slack, and RSS. Every channel, one source of truth.
The widget
Drop “What’s New” into your app
One script tag. Your users get a badge when something ships, a feed when they click, and a place to react — without ever leaving your product.
Paste before the closing body tag

Loved by product teams
The changelog stopped being a chore
“We shipped for two years without telling anyone. Signal turned our merge history into a changelog our customers actually bookmark — support tickets asking “did you fix X?” basically vanished.”
Mara Chen
Head of Product, Northwind
“The drafts are shockingly good. It reads the PR, skips the refactor noise, and writes the sentence I would have written — twenty minutes of dread down to one approve click.”
Eli Ambrose
Engineering Lead, Lumeo
“The widget pays for itself. Feature adoption on new releases doubled once What's New started badging inside the app instead of dying in an email nobody opens.”
Priya Raghavan
Founder, Basecoat
FAQ
Answers, before you ask
Everything teams check before switching their changelog to Signal.
Does Signal publish without my approval?
Never by default. Every release lands as a draft you review, edit, and approve. Teams that trust the pipeline can turn on auto-publish per project — it's one toggle, and it's off until you say otherwise.
What does it connect to?
GitHub, Linear, and Jira today, with GitLab in beta. Signal reads merged pull requests, closed issues, and shipped tickets — it never needs write access to your code.
Can I keep my existing changelog URL?
Yes. Point your domain or subdomain at Signal and we serve the hosted changelog there, certificate included. Existing URLs can be redirected release-by-release so old links keep working.
How customizable is the widget?
Colors, fonts, corner radius, position, and dark mode are all configurable from the dashboard — no rebuild, changes apply live. It ships as one small script tag with no iframe.
Where does the feedback go?
Reactions and comments attach to the release, and feature requests can be routed straight into your tracker as issues with the customer's context attached — so the loop closes where your team already works.
Is there a free plan?
Yes — one project, the hosted changelog, and the widget, free forever. Paid plans add AI drafting, email and Slack delivery, custom domains, and more teammates.
