Context

You do not search your workspace anymore. You text it.

Context is a native iOS AI teammate that lives in a messaging interface. It connects to your work tools, understands what changed, and replies like a concise coworker — not like a dashboard.

Why

Modern work is scattered across GitHub, Notion, calendars, Slack, and tickets. The common workflow is still manual: open five apps, scan updates, decide what matters, then act.

Context flips that interaction. You ask:

What should I work on first?

Context reads your workspace, reasons across sources, and responds with a prioritized answer plus tappable source cards.

What Works

• Native SwiftUI chat UI inspired by Apple Messages.
• FastAPI backend with streaming-compatible responses.
• Groq-powered LLM for fast development responses.
• Real GitHub reads for repo metadata, PRs, issues, commits, reviews, and checks.
• Notion page support for launch notes and project context, with demo fallback when unconfigured.
• Real Calendar ICS reads for today's events and meetings.
• Slack connector for team updates, with demo fallback when unconfigured.
• Workspace setup sheet for demo configuration without editing app code.
• Daily brief endpoint that summarizes GitHub, Notion, Calendar, and Slack context without a user prompt.
• Local conversation history so the chat survives app relaunches.
• Thinking states like "Searching GitHub," "Reading Notion," "Checking Calendar."
• Tappable source cards with native iOS preview sheets.
• Safe action drafts for GitHub issues, PR comments, and calendar events.
• Confirmed GitHub issue creation and PR comment posting through the backend.
• New Chat button to start fresh conversations.

Demo Flow

1. Open the app.
2. Context sends a morning brief.
3. Ask: What should I work on first?
4. Context checks GitHub, Notion, and Calendar.
5. Context recommends the highest-priority work with sources.
6. Tap a source card to inspect evidence.
7. Tap Draft issue to prepare an action.
8. Confirm creation only when ready.

Architecture

iOS SwiftUI app
  ├─ ChatView / ChatViewModel
  ├─ Source cards and action preview sheets
  └─ APIClient

FastAPI backend
  ├─ /chat — streaming-compatible response stream
  ├─ /brief — daily workspace brief
  ├─ /connections — configured/demo source status
  ├─ /workspace/setup — runtime demo workspace configuration
  ├─ /actions/draft/github-issue
  ├─ /actions/draft/github-pr-comment
  ├─ /actions/draft/calendar-event
  ├─ /actions/create/github-issue
  ├─ /actions/create/github-pr-comment

  └─ Groq LLM provider

Tech Stack

• iOS: SwiftUI, async/await, MVVM
• Backend: Python, FastAPI, Pydantic
• AI: Groq for development LLM responses
• Workspace APIs: GitHub REST API, Notion API, iCal/ICS calendar feeds, Slack Web API
• Testing: pytest, httpx ASGI tests

How Codex And GPT-5.6 Were Used

Codex

Codex served as the primary engineering teammate throughout the hackathon build:

• Designed and iterated the SwiftUI chat architecture.
• Built the FastAPI backend and streaming-compatible chat contract.
• Implemented real GitHub, Notion, and Calendar connectors.
• Added a lightweight workspace setup flow for demo configuration.
• Created safe action endpoints for drafting and confirming GitHub issue creation and PR comments.
• Wrote backend tests for connectors, orchestration, and action flows.
• Debugged iOS-to-backend streaming and converted it into a stable demo flow.
• Shaped the product narrative, Devpost positioning, and demo story.

GPT-5.6

GPT-5.6 served as the planning and product reasoning partner:

• Refined the "AI teammate you text" concept.
• Prioritized MVP scope under hackathon constraints.
• Reviewed UX copy so Context sounds like a coworker, not a chatbot.
• Identified the strongest demo path: brief → prioritization → evidence → action.

Try The Chat Endpoint

The iOS demo currently points to the local FastAPI backend at http://127.0.0.1:8000.

curl -N -X POST http://127.0.0.1:8000/chat \
  -H 'Content-Type: application/json' \
  -d '{"message":"What should I work on first?"}'
