🌟 Inspiration

Fax machines are long dead — relics from the era of landlines, dial tones, and dimly lit office cubicles. But there’s something undeniably charming about their clunky plastic shells, shrieking modem noises, and jittery printed pages. When Kiroween challenged us to resurrect dead technology, the answer became obvious:

Why bring back a fax machine for business paperwork… when we could bring it back as a supernatural communication portal?

Thus, GhostFax was born — a 1990s fax terminal redesigned to send messages into the afterlife and receive haunted faxes back. It blends nostalgia, horror comedy, AI creativity, and retro UI design into a single ridiculous, spooky, delightful experience.

It turns dead tech into a gateway for… more dead things.

👻 What it does

GhostFax lets users:

📠 Send “faxes” to realms beyond the living, including:

Limbo
The Afterlife DMV
The Underworld
Heaven Triage
The Lost & Found Dimension
The Archive of Dead Startups
The Realm of Obsolete Technology

👥 Choose supernatural recipients, like:

Ancestors
Expired packages
Lost socks
Dead startups
Netscape Navigator Dev Team
Ghosts of old gadgets

🖤 “Transmit” with haunted audio-visual effects

glitchy CRT flickers
distorted modem screeches
static overlays
“piercing the veil…” status messages

📄 Receive AI-generated reply faxes from the afterlife

Each fax includes:

realm-specific letterheads
ethereal seals
glitch artifacts
bureaucratic stamps
spooky tone and lore
full narrative responses

GhostFax takes a form of technology that no longer has relevance in the modern world and reimagines it as a supernatural story engine, wrapped in a retro-accurate 1990s interface.

🛠️ How we built it

GhostFax is built using:

🖥️ Frontend

Next.js 15 (App Router)
TypeScript
TailwindCSS with a custom retro-beige fax theme
WebAudio API for modem screeches & ambient hauntings
CRT screen effects, paper-feed animations, pixel fonts

🧠 AI Layer (powered with Kiro)

We leveraged Kiro heavily for:

Vibe Coding

Brainstorming afterlife realms, personalities, tone, and lore
Generating supernatural bureaucracies and cosmic error messages
Co-creating the “GhostFax Universe”

Spec-Driven Development

Realm definitions
Recipient archetypes
Fax header/footers & ASCII seals
Glitch rules
Narrative response templates

Agent Hooks

Automations trigger when:

a fax is sent
a realm is added
a reply is generated
lore data updates

Hooks handle:

formatting
glitch generation
seal stamping
routing logs
tone enforcement

Steering Docs

We wrote strict steering docs enforcing:

spooky-but-funny voice
retro fax aesthetic
analog-horror style replies
cosmic office humor

MCP Extensions

Custom MCP tools generate:

ASCII glitches
redaction overlays
supernatural seal stamps
noise textures for haunted artifacts

📦 Backend & Storage

Supabase for storage and inbox/archive
AI pipeline for reply generation
PDF renderer for fax-like documents
No real fax providers used (no cost, no dependencies)

Challenges we ran into

1. Making fake faxes feel real

We wanted transmissions to feel like actual documents passing through a supernatural phone line. This required:

glitch simulation
synthetic corruption
timing randomness
audio layering

2. Maintaining consistent narrative tone

With many realms and characters, replies could drift. Kiro steering docs solved this beautifully.

3. Designing believable realms

How do you give a fax from the Underworld a different vibe than one from Limbo? Specs and hooks helped standardize personalities.

4. Balancing horror and humor

We aimed for “playfully spooky,” not “genuinely terrifying.” Fine-tuning prompts took time.

5. Retro UI accuracy

Replicating a 1990s fax terminal required:

CRT distortions
soft shadows
analog noise
pixel-perfect fonts

🏆 Accomplishments that we're proud of

Resurrecting a dead technology in a wildly imaginative way
Creating an AI-powered story engine disguised as a fax machine
Achieving a perfect retro experience, both visually and audibly
Building a completely new use case from an existing app
Designing a multi-realm supernatural world with consistent lore
Leveraging every major Kiro feature (vibe, specs, hooks, steering, MCP)
Creating the most haunted office equipment ever made

The end result is fun, eerie, nostalgic, and unlike anything we’ve ever built before.

What we learned

1. Specs + Hooks = Superpowers

Kiro’s specs let us formalize creative ideas. Hooks automated entire narrative workflows.

2. Steering docs matter for creativity

Tone control is everything when generating stylized AI content.

🔊 3. Audio transforms an experience

Fax noises + spectral distortions = instant immersion.

👻 4. You can resurrect dead tech without APIs

No Twilio. No fax provider costs. Just creativity.

5. Kiro expands imagination, not just productivity

It didn’t just help code. It helped invent worlds.
