# kongruity
|
||||
|
||||
kongruity employs Large Language Model ("LLM") semantic grouping functionality to cluster large volumes of "to dos" or issue tags in development (or other) settings, according to thematic or topical similarity.
|
||||
kongruity pulls in the unstructured artifacts of the creative-engineering process -- to-dos, action items, agile tickets, Jira comment threads, Slack threads, retrospective notes -- and synthesizes them into semantically coherent, prioritized clusters ready for implementation planning.
|
||||
|
||||
(To learn more about this topic, see, e.g., [Kozlowski A., Boutyline A., Semantic Structure in Large Language Model Embeddings Aug. 2025, arXiv:2508.10003v1:04 Aug 2025](https://arxiv.org/html/2508.10003v1)).
|
||||
In kongruity world, these artifacts are "sticky notes." A board full of them looks chaotic. With a click, an LLM analyzes their semantic meaning and groups them into thematic clusters, each with a descriptive header.
|
||||
|
||||
In kongruity world, "to dos", action items, agile tickets... the myriad artifacts of the creative/engineering process, are "sticky notes."
|
||||
An independent embedding-based evaluation scores clustering quality, so the output is data-backed. From there, teams can simply drag-and-rank clusters by implementation priority, turning noise into an actionable workflow.
|
||||
|
||||
kongruity's React/Vite UI displays a board of seemingly chaotic "sticky notes". But with one click, they are transformed into manageable, actionable groups, each with a header that explains that group's semantic relation.
|
||||
## How it works
|
||||
|
||||
The backend is an Express API that serves "sticky note" data and proxies semantic grouping requests to Large Language Models.
|
||||
1. **Ingest** — Sticky notes are loaded and displayed on a board.
|
||||
2. **Cluster** — An LLM reads every note and groups them by semantic similarity (not keywords).
|
||||
3. **Evaluate** — In parallel, a separate embedding model (Voyage AI) generates vector representations of each note. A silhouette-based cohesion score measures how well-separated and internally consistent clusters are. The score is displayed alongside the results.
|
||||
4. **Validate** — Structural checks confirm every note is assigned to exactly one cluster, no clusters are empty, and labels are present.
|
||||
5. **Prioritize** — Clusters appear ranked and are drag-reorderable. Teams set implementation priority by dragging clusters into position.
|
||||
|
||||
Developers may freeely swap in other LLM SDKs and/or APIs... and alter prompt syntax at backend/services/clustering.service.js to compliement their experimentation with any LLM model/platform they prefer.
|
||||
## Dev implementation note
|
||||
|
||||
Developers may swap in other LLM SDKs/APIs and alter prompt syntax in `backend/services/clustering.service.js` to experiment with any model or platform.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- Node.js (v18 or later recommended)
|
||||
- An [Anthropic API key](https://console.anthropic.com/)
|
||||
- PostgreSQL (v14 or later recommended)
|
||||
- An [Anthropic API key](https://console.anthropic.com/) (or other LLM platform, for clustering)
|
||||
- A [Voyage AI API key](https://dash.voyageai.com/) (for embedding-based evaluation)
|
||||
|
||||
## Setup
|
||||
|
||||
### 1. Unzip the project
|
||||
### 1. Clone the repository
|
||||
|
||||
```bash
|
||||
unzip kongruity.zip
|
||||
git clone https://github.com/kjannette/kongruity_
|
||||
cd kongruity
|
||||
```
|
||||
|
||||
### 2. Create an environment file
|
||||
|
||||
The backend expects a `.env` file containing an Anthropic API key in the root `backend/` directory. This file is git-ignored and must be created manually:
|
||||
The backend expects a `.env` file in the `backend/` directory. This file is git-ignored and must be created manually:
|
||||
|
||||
```bash
|
||||
echo 'ANTHROPIC_API_KEY=<your Anthropic API key>' > backend/.env
|
||||
cat > backend/.env << 'EOF'
|
||||
ANTHROPIC_API_KEY=<your Anthropic API key> (or other LLM platform key)
|
||||
VOYAGEAI_API_KEY=<your Voyage AI API key>
|
||||
DATABASE_URL=postgresql://<user>:<password>@localhost:5432/kongruity
|
||||
EOF
|
||||
```
|
||||
|
||||
Replace `<your Anthropic API key>` with your actual key.
|
||||
Replace placeholder values with your actual keys and database credentials.
|
||||
|
||||
### 3. Install dependencies
|
||||
### 3. Set up the database
|
||||
|
||||
Create a PostgreSQL database for the project:
|
||||
|
||||
```bash
|
||||
createdb kongruity
|
||||
```
|
||||
|
||||
Run the migration to create tables:
|
||||
|
||||
```bash
|
||||
cd backend
|
||||
npm run db:migrate
|
||||
```
|
||||
|
||||
Seed the database with the sample sticky notes:
|
||||
|
||||
```bash
|
||||
npm run db:seed
|
||||
```
|
||||
|
||||

# Database — kongruity backend
|
||||
|
||||
PostgreSQL database layer for the kongruity backend. All database modules live in this directory.
|
||||
|
||||
## Prerequisites
|
||||
|
||||
- PostgreSQL v14 or later
|
||||
- The `DATABASE_URL` environment variable set in `backend/.env`
|
||||
|
||||
## Configuration
|
||||
|
||||
### Environment variable
|
||||
|
||||
The connection pool reads a single env var:
|
||||
|
||||
```
|
||||
DATABASE_URL=postgresql://<user>:<password>@localhost:5432/kongruity
|
||||
```
|
||||
|
||||
This is loaded via `dotenv` from `backend/.env` (git-ignored). The pool is created once in `index.js` and shared across the application.
|
||||
|
||||
### Connection pool (`index.js`)
|
||||
|
||||
| Export | Description |
|
||||
|-------------|--------------------------------------------------|
|
||||
| `query` | Execute a parameterized SQL statement |
|
||||
| `getPool` | Return the underlying `pg.Pool` instance |
|
||||
| `close` | Gracefully shut down the pool (`pool.end()`) |
|
||||
| `default` | The pool itself (default export) |
|
||||
|
||||
## Schema
|
||||
|
||||
### `notes` table
|
||||
|
||||
Created by the migration in `migrate.js`. The DDL is idempotent (`CREATE TABLE IF NOT EXISTS`).
|
||||
|
||||
| Column | Type | Constraints / Defaults |
|
||||
|---------------|----------------|------------------------------|
|
||||
| `id` | `VARCHAR(64)` | `PRIMARY KEY` |
|
||||
| `text` | `TEXT` | `NOT NULL` |
|
||||
| `x` | `INTEGER` | `DEFAULT 0` |
|
||||
| `y` | `INTEGER` | `DEFAULT 0` |
|
||||
| `author` | `VARCHAR(128)` | |
|
||||
| `color` | `VARCHAR(32)` | `DEFAULT 'yellow'` |
|
||||
| `source_meta` | `JSONB` | `DEFAULT '{}'` |
|
||||
| `created_at` | `TIMESTAMPTZ` | `DEFAULT NOW()` |
|
||||
| `updated_at` | `TIMESTAMPTZ` | `DEFAULT NOW()` |
|
||||
|
||||
## npm scripts
|
||||
|
||||
Run these from the `backend/` directory.
|
||||
|
||||
### Migrate
|
||||
|
||||
Creates the `notes` table (safe to re-run):
|
||||
|
||||
```bash
|
||||
npm run db:migrate
|
||||
```
|
||||
|
||||
### Seed
|
||||
|
||||
Inserts 50 sample sticky notes. Uses `ON CONFLICT (id) DO NOTHING`, so re-running is safe and will not duplicate data:
|
||||
|
||||
```bash
|
||||
npm run db:seed
|
||||
```
|
||||
|
||||
## Data access layer (`notes.dao.js`)
|
||||
|
||||
| Function | Description |
|
||||
|---------------------------|--------------------------------------------------------------------|
|
||||
| `getAllNotes()` | Returns all notes ordered by `id` |
|
||||
| `getNoteById(id)` | Returns a single note by primary key, or `null` if not found |
|
||||
| `createNote(note)` | Inserts one note and returns the created row |
|
||||
| `createNotes(notes)` | Bulk-inserts an array of notes in a single query and returns rows |
|
||||
|
||||
All functions return plain objects with columns: `id`, `text`, `x`, `y`, `author`, `color`.
|
||||

||||

|

|
||||
## Useful psql commands
|
||||
|
||||
Connect to the database:
|
||||
|
||||
```bash
|
||||
psql kongruity
|
||||
```
|
||||
|
||||
Quick checks:
|
||||
|
||||
```sql
|
||||
-- Row count
|
||||
SELECT count(*) FROM notes;
|
||||
|
||||
-- Preview data
|
||||
SELECT id, text, color FROM notes LIMIT 10;
|
||||
|
||||
-- Full schema info
|
||||
\d notes
|
||||
|
||||
-- Drop and re-seed (destructive)
|
||||
TRUNCATE notes;
|
||||
```
|
||||
|
||||
Then re-seed:
|
||||
|
||||
```bash
|
||||
npm run db:seed
|
||||
```
|
||||
|
||||
## Resetting the database
|
||||
|
||||
To start completely fresh:
|
||||
|
||||
```bash
|
||||
dropdb kongruity
|
||||
createdb kongruity
|
||||
cd backend
|
||||
npm run db:migrate
|
||||
npm run db:seed
|
||||
```
