Launch your plugin like you have a PR team.
SignalChain is the all-in-one workspace that turns a plugin, soundset, or sample-library launch into a guided press campaign — a curated database of the audio-press outlets that matter, AI that writes the exact pitch each one wants, plus press releases, social copy, a launch checklist, and ad assets.
Launching a plugin shouldn't mean a spreadsheet of 50 emails — or a $3k agency.
You can build the DSP. The marketing is the part no one teaches: who to email, what each outlet actually wants, when to send, what a press release should say, and how to keep track of it all. Most indie devs wing it from forum threads — or pay a retainer they can't justify. SignalChain is the system in between.
Everything a plugin launch needs, in one workspace
Each module maps to a real step in getting your release covered.
Curated outlet database
A vetted, stage-organized list of audio-press outlets — news sites, magazines, review blogs, and YouTube reviewers — each with its contact method and what it wants. The chain walks you from day-one submissions to paid amplification.
Per-outlet AI pitches
Describe your product once; SignalChain writes the specific pitch each outlet expects — a KVR news item, an editorial story angle, a review request with NFR offer — grounded in your scraped product page, never a generic blast.
Press releases
Generate a full, industry-format press release from your product facts, edit it inline, and export a clean PDF with your brandmark letterhead.
Social copy
Platform-native posts for Facebook, X, Reddit, Threads, Instagram, Mastodon and more — tuned to each network's limits, tone, and link rules, with a Reddit self-promo guardrail.
Launch checklist
A drag-to-reorder launch playbook per project so nothing slips between beta and launch day.
Ad & banner generation
Exact-size vector banners with crisp text via Claude, plus optional photoreal raster heroes — download as SVG/PNG or save to the project.
From product page to press campaign in three steps
Describe your product
Paste your product URL or fill in the details. SignalChain scrapes the page so every generation is grounded in real facts about your plugin.
Generate outlet-specific outreach
Pick an outlet and generate the exact pitch it wants — plus social posts, a press release, and ad assets — all in your voice, not a template.
Track your outreach to launch
Move each outlet through the chain, check off your launch tasks, and keep every generated asset in one place through release day.
Pitch the outlets that actually review audio software
SignalChain's curated database covers the audio-press tier indie devs struggle to reach — organized into launch stages, each with the contact method and angle that works.

Questions indie developers ask
What is SignalChain?
SignalChain is a release-ops tool for independent audio-software developers. It helps you run press and social outreach for a plugin or sample-library launch using a curated outlet database, AI-generated outlet-specific pitches, press releases, social copy, launch checklists, and AI ad generation.
Who is it for?
Indie audio-software developers and small plugin companies who make VST/VSTi plugins, soundsets, sample libraries, or standalone music apps and need help marketing and getting press coverage for a launch — without hiring a PR agency.
Is it free?
Yes — you can start free with a guest mode or a free account. You add your own AI provider key (Anthropic, OpenAI, or Google) for the AI generation features, so you control cost and provider.
Do I need a PR agency to launch a plugin?
No. Most indie plugin launches are won with targeted, personalized outreach to the right audio-press outlets — exactly what SignalChain structures and automates, at a fraction of an agency retainer and fully in your control.
Which outlets does it cover?
A curated set of audio-software press and review outlets — news sites, magazines, review blogs, and YouTube reviewers — organized into launch stages, each with its preferred contact method and the kind of pitch it wants.
