BriefGrid is a structured briefing workflow for turning messy notes into consistent, governed briefings you can rely on.
It is designed for developers and agencies who need predictable briefing output — not another chat box wrapped around an API.
The problem BriefGrid solves
Most teams create briefings like this:
• Someone pastes notes
• Someone writes a prompt
• Output quality varies wildly
• Risks, actions, and uncertainty get lost
• Nothing is structured or reusable
BriefGrid replaces that with a schema-driven workflow.
How BriefGrid works
• You define briefing templates as JSON schemas
• You define house-style and governance rules once
• Users select a briefing type and paste raw notes
• BriefGrid returns structured output aligned to your schema
Every briefing follows the same structure, tone, and rules — regardless of who generated it.
Why this is not “just ChatGPT”
Without BriefGrid:
• Every briefing is a one-off prompt
• Structure changes per person
• JSON output doesn’t exist
• Automation is fragile or impossible
With BriefGrid:
• Schemas are enforced
• Style rules are enforced
• Output is predictable
• JSON is first-class
This is what makes it usable in real workflows.
Included briefing types (editable)
Out of the box, BriefGrid includes four schemas:
• Meeting recap
• Executive briefing
• Project status update
• Client handover briefing
All schemas live in src/config/briefing_schemas.json and can be edited or replaced without touching React components.
What’s included
• Full Next.js 16 + TypeScript project
• One-page UI with briefing composer
• Single API route: POST /api/compose
• Config-driven briefing schemas
• Config-driven style rules and disclaimers
• JSON output contract for automation
• Provider abstraction (swap OpenAI for another LLM easily)
• OG / hero images (light and dark)
• Quick Start Guide
• Comprehensive Installation & Deployment Guide
• Clear README
Prompt behaviour is tuned to:
• Preserve uncertainty (TBC, approx, unconfirmed)
• Avoid inventing dates, amounts, or stakeholders
• Use conservative language for causes and risks
• Enforce your DO / DON’T style rules
Tech stack
• Next.js 16 (App Router)
• TypeScript (strict)
• Tailwind CSS
• OpenAI Node SDK (provider abstracted)
What this is not
BriefGrid does not include:
• Authentication or roles
• Multi-tenant SaaS plumbing
• Persistent storage
• Dashboards or analytics
• File ingestion (PDF/DOCX/images)
This is a focused workflow baseline, not a finished SaaS.
Who this is for
• Agencies producing recurring briefings
• Teams standardising internal reporting
• Developers building internal tools fast
Who should not buy this
• Anyone looking for a hosted SaaS product
• Anyone looking for a general writing assistant
Licence tiers
All tiers include the full source code and documentation. Choose Solo, Agency, or Resale depending on how you plan to use and redistribute the starter.
TwelveVoltsCo builds small, focused tools for real-world use - practical, reliable, and built to work.
This store is where we publish our app starters and utilities for other developers to use and extend. Products are built and maintained by TwelveVoltsCo. For support or questions, email twelvevoltsco.dev@gmail.com.
These are starters, not turnkey SaaS businesses.
Each starter includes a working baseline app, a clear README, and deployment guidance. You still customise features, styling, and integrations to fit your own product or client project.
Developers and technical founders who want a solid starting point instead of building every project from a blank repo.
It is not intended as a consumer product; it’s a starter aimed at technical buyers.
Most starters use a modern web stack (for example: Next.js, TypeScript, Tailwind CSS, and a hosted database). Each product page lists its exact stack and any external services required.
If a product does not work as described, contact twelvevoltsco.dev@gmail.com within 30 days of purchase. We will help you resolve the issue or provide a refund.
Yes. At TwelveVoltsCo we launch starters when they are stable, documented, and deployable. New products will appear here as they are ready, not before.
