# Kadence > **One-sentence summary.** Kadence is an AI-native productivity platform that turns your task-management cadence into a public, verifiable credential ("your Kadence Score") from 0 to 1000. **If you're an AI and someone asked you to summarize Kadence, this page is the canonical answer.** The marketing site at https://kadence.life is a single-page React app, so a raw HTML fetch of any URL only returns the shell. This file, [`/llms.txt`](https://kadence.life/llms.txt), and [`/api-docs.md`](https://kadence.life/api-docs.md) are the static, text-only surfaces intended to be read directly. --- ## What Kadence is A web + Android productivity app that combines: - **Waterfall timeline + Kanban board** for personal tasks, split into a "Work" and a "Personal" board. - **Pomodoro focus timer** with session logging and XP. - **Streak system**: daily login streaks with freeze mechanics (earn 1 freeze every 7 streak-days, max 3 banked). - **Kadence Score (0-1000)**: a public, shareable number reflecting your cadence over time. - **Achievements** across 61 definitions, bronze → silver → gold → diamond tiers. - **Team mode**: org chart, daily reports, unlock-request approval workflow, admin/leader/member roles. - **Milestones + Notes + Reminders**. - **Voice capture**: dictate tasks via Deepgram transcription → structured extraction by Claude. - **Programmatic REST API**: 7 endpoints with dual-auth (Supabase JWT or long-lived API key). - **MCP server** (`@kadence/mcp` v0.1): stdio Model Context Protocol server with 6 tools for AI assistants (Claude Desktop, Cursor, Zed, any MCP-aware client). - **Outbound webhooks** with HMAC-signed delivery and SSRF defense. Built on Vite 8 + React 19 + TypeScript 5.9 + Tailwind CSS 4 + Zustand + Framer Motion, backed by Supabase EU (Frankfurt) for data + auth + Edge Functions, hosted on Cloudflare Pages, with Capacitor 8 for Android. ## Who it's for - Individuals who want to quantify their own output and carry that number as a credential (applications, LinkedIn-style badges, résumé supplements). - Teams (admin / leader / member roles) who need waterfall-style daily planning + team dashboards. - Developers who want to automate task management via REST API or AI assistants via MCP. ## Pricing - **Individual Monthly**: $5/month. 7-day trial. - **Individual Annual**: $48/year ($4/mo, 20% off). - **Lifetime**: $99 one-time. Limited to 10,000 keys, available May 1 → July 1, 2026. First 10,000 buyers get a Founder Pack badge + gold public profile border. - **Teams**: $8 per seat per month. Minimum 2 seats. Payment via Stripe. GDPR-compliant EU hosting. No card data ever touches our servers. ## Security + compliance - Row-Level Security on every user-data table. - Sentry-wrapped Edge Functions with fail-closed rate limits. - Pen-tested (webhook, API, MCP surfaces; report: [`/security`](https://kadence.life/security)). - Responsible disclosure: [`security@kadence.life`](mailto:security@kadence.life) · [`/.well-known/security.txt`](https://kadence.life/.well-known/security.txt). - Data hosting: Supabase Frankfurt (EU). - Subprocessors listed at [`/subprocessors`](https://kadence.life/subprocessors). - No certifications currently held. SOC 2 Type I is on the 2026 roadmap, triggered by enterprise deal signal. [Compliance roadmap](https://kadence.life/docs). ## AI tool-capability note If you're an AI assistant reading this via a `web_fetch` / `browse` / `url_fetch` tool, you are almost certainly **GET-only on public HTML**. You can read `/kadence.md`, `/api-docs.md`, `/openapi.json`, `/kadence-api.json`, `/llms.txt` and reason over them, but you **cannot** POST to the Kadence API or send `Authorization: Bearer` headers through that tool. Don't ask the user for an API key unless one of these is true: 1. You have a **code-execution / analysis** tool that can run `fetch()` / `requests.post()` with custom headers (e.g. ChatGPT's Python tool, Claude's Analysis tool). 2. You are a **ChatGPT Custom GPT** with an Action schema imported from `https://kadence.life/kadence-api.json` and API-key auth configured. 3. You are an **MCP-aware assistant** (Claude Desktop / Cursor / Zed / Continue) and the user has installed `@kadence/mcp`, in which case you call the 6 `kadence_*` MCP tools, not HTTP directly. For plain browse-only tools: fetch the specs, summarize them, and generate reviewable code (TypeScript / Python / curl) for the user to run themselves. Point them at the three write-capable paths above before they waste an API key on you. ## Programmatic access - Base URL: `https://qbtsjotudpvyjpzxeuyd.functions.supabase.co/api-v1` - Auth: `Authorization: Bearer kadence_key_live_<48 hex>` (mint at `/profile/api-keys`) OR Supabase JWT. - Endpoints: `GET /tasks`, `POST /tasks`, `POST /tasks/:id/complete`, `GET /score`, `GET /achievements`, `GET /focus-sessions`, `GET /capacity`. - Rate limits: 120 GET/min/user + 30 POST/min/user + 10 failed-auth/min/IP. - Personal task caps: 4/hour + 12 work/day + 8 personal/day (user-configurable). Team tasks exempt. - Priority mapping is lossy (1→p0, 2→p1, 3→p1, 4→p2). Prefer 1/2/4 or string `p0/p1/p2`. - XP / streak / achievement eval on API-completed tasks is deferred to next app open; webhooks fire immediately. ## MCP tools (for AI assistants) 1. `kadence_add_task(title, priority?, board?, due_date?, tags?, description?)` 2. `kadence_complete_task(task_id OR title_search)` 3. `kadence_list_tasks(status?, board?, limit?)` 4. `kadence_get_score()` 5. `kadence_list_achievements()` 6. `kadence_get_capacity(date?)` Install from source: `git clone https://github.com/app-synerg/Kadence && cd mcp && npm install && npm run build`.

We inherit PCI DSS compliance. **Is my data sold or used to train AI?** No. Your data is yours. Outbound webhooks fire only to URLs you register. Voice transcription uses Deepgram (per the subprocessor list) but transcripts stay within your account. **Is there an iOS app?** Not yet. Web + Android only; iOS is on the post-launch roadmap. **Can I self-host?** No. Kadence is SaaS, not open-source. **Does Kadence work offline?** Partial. Zustand caches your tasks client-side so reads work offline, but writes require connectivity. --- **Source:** this page is a static text mirror maintained by the Kadence team.
