Smart Content Repurposing Engine

Problem and target customer

Why this exists

Customer problem

Creators and lean marketing teams repeatedly reshape the same long-form material for newsletters and social channels. Copying text into separate tools loses source context, tone constraints, draft lineage, and a reliable final approval step.

Who pays

Solo creators and small content teams that publish one long-form source and manually adapt it into several text-led channel formats each week.

Business model

Monthly subscription with a transformation allowance and higher tiers for longer sources and retained assets.

Editorial note

The source version is the product's anchor. Channel recipes, tone settings, and generated drafts can change, but a reviewer must always be able to see which approved text produced an output and whether later source edits made it stale.

Repurposing should mean structural adaptation, not synonym replacement. A newsletter, thread, short post, and article outline have different constraints, yet each must remain bounded by the same source claims and explicit call to action.

Measure approval work, not generation volume. The meaningful signals are time to approved package, edits per format, unsupported claims, and how often users abandon a draft for an external tool.

Product goal

Who it serves and what it must change

Target user: A solo creator or small marketing team republishing one authoritative article, transcript, podcast, or video across text-led channels.
Problem: Each derivative is drafted in isolation, so claims drift from the source, tone settings are repeated manually, and teams cannot tell which version was approved.
Measurable outcome: One source produces a reviewed newsletter draft, short social post set, thread, and article outline with every output traceable to the source version.

MVP scope

What ships now and what waits

Included

Core entity outline

Entities and business rules

SourceAsset

Represents the imported text, document, audio, or video and its extraction state.

Fields: id, owner_id, kind, object_key, duration_seconds, status, rights_confirmed_at
Relations: has many source versions, has many transformation runs

SourceVersion

Stores one immutable corrected text used to ground outputs.

Fields: id, source_asset_id, version, normalized_text, checksum, approved_at
Relations: belongs to one source asset, grounds many transformation runs

ToneProfile

Defines audience, voice traits, required CTA, prohibited phrases, and claim constraints.

Fields: id, owner_id, name, audience, traits, cta, prohibited_phrases
Relations: belongs to one owner, used by many transformation runs

OutputRecipe

Defines a bounded format with structural limits rather than marketing keywords.

Fields: id, format, instructions, max_length, required_parts
Relations: used by generated outputs

TransformationRun

Freezes source version, tone profile, selected recipes, and stage results.

Fields: id, source_version_id, tone_profile_snapshot, status, created_at
Relations: belongs to one source version, has many generated outputs, has many jobs

GeneratedOutput

Versions one channel draft and its source anchors, review state, and edits.

Fields: id, run_id, recipe_id, version, body, source_anchors, status
Relations: belongs to one transformation run, may be included in one export

ExportBundle

Lists the exact approved output versions delivered to the user.

Fields: id, run_id, output_version_ids, manifest, created_at
Relations: belongs to one run, contains approved generated outputs

Business rules

Generation is blocked until a source version is approved and rights confirmation is recorded.
A transformation run stores snapshots of tone and recipe instructions so later settings changes do not alter its meaning.
Every generated output must reference at least one source section and may not introduce external factual claims by instruction.
Regeneration creates a new output version; user edits never overwrite the provider response.
Only approved output versions can enter an export bundle.

Architecture and data flow

Components, integrations, and controls

Review web application

Handles source correction, recipe setup, draft editing, approval, and export.

Extraction worker

Parses supported documents and transcribes audio or video into normalized source text.

Generation orchestrator

Builds source-bounded requests per recipe and preserves independent retry state.

Relational database

Stores source versions, tone snapshots, recipes, output versions, reviews, and jobs.

Private object storage

Holds uploaded sources and export bundles behind signed URLs.

Integrations

ElevenLabs Scribe or another speech-to-text provider for audio and video sources.
An LLM API for source-grounded channel drafts.
S3-compatible storage for source files and export archives.
Make as an optional post-approval delivery to a CMS, newsletter tool, or scheduler.

Data flow

The browser uploads a source or submits pasted text, then creates an extraction job if needed.
The user corrects extracted text and approval freezes an immutable source version.
The orchestrator creates one job per selected recipe using the frozen source and tone snapshot.
Each provider response is stored as a version with source anchors before the user edits or approves it.
Export reads approved version ids and creates a text package plus manifest.

Failure handling

If extraction fails, keep the source record and offer retry or manual text paste.
If one recipe fails, preserve successful drafts and retry only that recipe with the same frozen inputs.
If the source is edited, mark outputs from older versions stale rather than silently updating them.
If export fails, recreate it from approved version ids without regenerating content.

Security

Use owner-scoped queries, signed object URLs, encrypted provider keys, and retention rules for abandoned uploads.
Treat documents and model output as untrusted text and prevent them from injecting system instructions into other jobs.
Record source-rights confirmation and keep private source text out of analytics and error logs.

Rate limits

Limit source bytes, audio duration, selected recipes, and concurrent runs per plan.
Apply provider-specific backoff and idempotency keys to extraction and generation.
Throttle regenerations per output while preserving user edits.

Deliverables and acceptance

Definition of done for the MVP

Deliverables

Responsive source intake, source review, recipe setup, Draft Studio, and export screens.
Document extraction, media transcription, generation, and export workers with job-state visibility.
Database migrations for source and output version lineage.
Test fixtures for text, failed media extraction, partial recipe failure, stale source, and approved export.

Acceptance criteria

A user can paste an article or upload supported media and approve a normalized source version.
Selected recipes generate independent drafts that identify the source version and survive another recipe's failure.
Editing the source marks existing outputs stale and blocks their export until a new run is reviewed.
Regenerating one draft retains earlier provider and user-edited versions.
An export failure can be retried without calling the LLM again, and the package contains only approved versions.

Data

PostgreSQL

Jobs

BullMQ with Redis

Storage

Cloudflare R2 or S3

LLM API plus ElevenLabs Scribe

The LLM transforms approved source text while speech-to-text normalizes media inputs.

Why this is sufficient

The product earns trust through source lineage and human approval, not one-click volume. Independent jobs and immutable versions make partial failures and corrections recoverable.
