RemixForge AI — One Story. Infinite Remixes.

#devchallenge #sanitychallenge #sanity #ai

Sanity Challenge Path Two Submission

This is a submission for the Sanity Challenge, Path Two: Vibe-Code Something Strange

What I Built

I built RemixForge AI, an AI-powered content remix workflow that turns one piece of content into multiple creative formats.

The idea is simple:

One story. Infinite remixes.

A creator can start with a video, story, article, or other source content. RemixForge AI organizes the content inside Sanity and creates structured remix possibilities such as:

AI summaries
Social media posts
Short-video ideas
GIF moments
Captions
Multilingual content

The interesting part is that AI generation is not treated as the final step.

RemixForge AI creates a structured workflow:

Create → AI Processing → AI Review → Human Review → Approve → Publish

AI creates the first version, while a human remains responsible for reviewing and approving the final content.

The project includes a custom dashboard and public showcase in addition to the embedded Sanity Studio.

Demo

Application

The project contains four main interfaces:

Homepage — introduction to RemixForge AI
Dashboard — AI Content Control Center
Showcase — scenes and AI-discovered GIF moments
Sanity Studio — structured content and workflow management

Sanity Studio
GROQ
Next.js API routes
Sanity Document Actions

How I Used Sanity

Sanity is the structured content and workflow backbone of RemixForge AI.

Instead of storing everything as unstructured text, I modeled the remix process as structured documents.

Remix Project

A Remix Project stores the original content and its high-level state.

It includes fields such as:

title
description
source type
source URL
workflow status
AI summary
mood
target languages
creation time

Scene

Scenes represent important moments detected or selected from the source content.

Each scene contains:

scene number
title
description
start time
end time
mood
GIF-candidate status

AI Output

AI-generated results are stored as their own Sanity documents.

An AI Output can represent:

summary
social post
short-video idea
GIF idea
translation
caption

Each output also stores:

language
confidence score
review status
generation time
reference to its Remix Project

GIF Moment

GIF Moments represent potentially reusable moments from the source content.

They contain:

source scene
start time
end time
AI reasoning
generation status
generated GIF URL
approval information

Workflow Run

The workflow itself is also modeled as data in Sanity.

A Workflow Run tracks states such as:

Draft → AI Processing → AI Review → Human Review → Approved → Published

It also records:

last action
last actor
assigned reviewer
workflow history
timestamps

This means the content and its editorial workflow live together as structured Sanity data.

Custom Sanity Features

I went beyond using Sanity only as a simple CMS.

The project includes custom document actions inside Sanity Studio.

For Remix Projects, there is a:

🤖 Send to AI

action.

This calls the application's AI processing API.

The API then:

Reads the Remix Project from Sanity
Updates the project workflow state
Creates a Workflow Run
Creates multiple AI Output documents
Moves the workflow into AI Review
Updates the project with the AI summary

Workflow documents also have actions for:

👤 Send to Human Review
✅ Approve
🚀 Publish

These actions update the structured workflow data and maintain workflow history.

--- Local: http://localhost:3000

Custom Interface

I also built a custom RemixForge AI dashboard instead of relying only on Sanity Studio.

The dashboard shows:

project statistics
AI output counts
workflow states
recent Remix Projects
generated AI outputs
human approval queue
the complete AI → Human → Publish pipeline

There is also a separate Showcase interface that presents:

detected scenes
scene timelines
AI-selected GIF moments
workflow stages

This gives the structured Sanity content a user-facing creative interface.

Why Sanity?

Sanity works particularly well for this project because the application is not just about storing a final article or video.

The application needs to store the relationships between:

Projects → Scenes → AI Outputs → GIF Moments → Workflow Runs

Sanity allows these pieces to remain structured and connected.

The workflow can therefore be treated as content and data rather than only application state.

What I Learned

The biggest lesson from building RemixForge AI was that structured content becomes much more interesting when the content itself participates in a workflow.

Instead of:

AI → Final Answer

the project explores:

Content → AI Generation → Structured Outputs → Review → Human Decision → Publishing

Sanity became the place where those pieces could be modeled, connected and moved through the workflow.

I also learned that building a working AI-native application involves much more than generating text. The difficult part is making the generated results useful, reviewable and connected to the rest of the application.

Dataset:

production

The Sanity project contains the structured models used by RemixForge AI, including Remix Projects, Scenes, AI Outputs, GIF Moments and Workflow Runs.

Agent Session

This section is optional.

I did not use one of the supported Agent Session CLI transcripts for this project, so I am not claiming an agent session that I do not have.
