ChronoCast: Multi-Platform Content Calendar for Video Teams

Problem and target customer

Why this exists

Customer problem

Small video teams plan cross-platform posts across YouTube, TikTok, and Reels using spreadsheets, chat threads, and memory, which causes missed publish dates and unclear approvals.

Who pays

3-person creator teams and marketing teams publishing weekly video content across YouTube, TikTok, and Instagram Reels.

Business model

Monthly subscription with a paid workspace tier for multi-seat collaboration and approval history.

Editorial note

ChronoCast replaces the spreadsheet-plus-chat workflow with one shared calendar where every video has a platform, an owner, a reviewer, and a publish date.

The MVP is intentionally narrow: plan, approve, and track cross-platform video posts, not auto-publish them.

Color-coded platform cards and a quick-add sidebar keep the editorial workflow visible without burying it in menus.

Product goal

Who it serves and what it must change

Target user: 3-person creator teams publishing weekly video content across YouTube, TikTok, and Reels.
Problem: Cross-platform video planning is split across spreadsheets and chat, causing missed publish dates and unclear approvals.
Measurable outcome: A 3-person creator team plans a full month of cross-platform content in under 30 minutes and tracks every video from idea to publish without using a spreadsheet.

Business rules

A content job must have a platform, an owner, a reviewer, and a publish date before it can leave Draft
Only the assigned reviewer can move a job from In Review to Scheduled or Changes Requested
A Scheduled job cannot be edited without returning it to Draft
Activity log entries are append-only and record every status change with actor and timestamp

Architecture and data flow

Railway-hosted ChronoCast API

Postgres database

Object storage for draft thumbnails

Object storage for draft thumbnails

Make scenario runner

Make scenario runner

Integrations

Calendar API for surfacing publish dates in external calendars
LLM API for summarizing reviewer comments into a short note
Object storage for draft video thumbnails
Make for exporting approved jobs to a platform checklist

Data flow

Creator submits content job form from Lovable to Railway API
Railway persists the content job and writes an ActivityLogEntry
Reviewer action updates status and triggers a Make scenario
Make writes the approved job to the platform export checklist and notifies the owner

Failure handling

If Make is unavailable, the approved job stays Scheduled and is retried on the next run
If the LLM summary fails, the raw reviewer comment is stored and shown instead
If object storage is unreachable, the content job still saves with a placeholder thumbnail

Security

Workspace-scoped authentication on every API route
Role checks for owner, reviewer, and admin actions
Signed URLs for draft thumbnail access
Append-only activity log to preserve audit history

Rate limits

Per-workspace limits on content jobs created per day
Per-user limits on reviewer comments per content job
Make scenario runs throttled to once per approved job

Deliverables and acceptance

Definition of done for the MVP

Deliverables

Lovable calendar UI with quick-add sidebar
Railway API with content job and approval endpoints
Postgres schema for workspaces, content jobs, and activity log
Make scenario for approved job export checklist
Activity log view per content job

Acceptance criteria

A 3-person creator team plans a full month of cross-platform content in under 30 minutes
Every content job shows platform, owner, reviewer, publish date, and current status
A reviewer can approve or request changes and the status updates within one second
Approved jobs appear on the platform export checklist within five minutes
The activity log records every status change with actor and timestamp

Implementation

S3-compatible object storage for draft video thumbnails

Why this is sufficient

Lovable handles the editorial calendar UI, Railway runs the durable content job records and approval state machine, Make bridges approved jobs to external checklists, and object storage holds draft thumbnails referenced by each content job.
