# AestimAi

> Universal Coin Index (UCI) — the missing measure of value. Valuation, barter marketplace, market data, and cooperative economics — open, transparent, and under active development.

AestimAi (pronounced ESS-tim-eye, /ɛs·tim·ai/) is a web platform at https://aestimai.org that builds and applies the **Universal Coin Index (UCI)**: a neutral, index-based reference unit for measuring the real exchange value of goods, services, energy, time, and resources. UCI is **not a currency** — it is an open index calibrated by real valuations and trades, independent of national currencies, inflation, and political decisions.

**Motto (Latin):** *du ut des* — I give, so you can give. The foundation of barter and cooperative exchange.

**Operator:** AestimAi / Sunthetics ecosystem. Official energy partner: Sunthetics AB (https://www.sunthetics.se) — EaaS solar + CHP2X solutions.

**Languages:** Swedish (sv), English (en), German (de), French (fr), Italian (it), Spanish (es). UI language is selectable in-app; much content is translated client-side.

**Mobile app:** Native iOS/Android app (separate repo) shares the same UCI backend and links to https://aestimai.org for upgrades and account management.

## What is UCI?

UCI (Universal Coin Index) addresses a fundamental gap: physical quantities have universal measures (metre, kilogram, second), but **value has no universal measure**. An hour of work or a kilo of bread has wildly different prices across currencies and regions. UCI provides a **neutral reference point** for exchange.

**Core properties:**
- **Neutral** — not tied to any single currency, nation, or institution; a public good
- **Universal** — same reference works in Malmö, Nairobi, Tokyo, or Lagos; no exchange rates in the index itself
- **Index-based** — value builds organically from real valuations, exchanges, and transactions
- **Transparent** — valuations and index logic are open and verifiable
- **Cooperative** — users who value and trade improve index precision for everyone
- **Circular** — designed for resource circulation and large-scale barter networks, not one-to-one coincidence of wants

**Why it matters:**
1. Fairer trades — shared reference reduces power asymmetry between "hard currency" and non-currency holders
2. Stability vs. currency fluctuation — 10 UCI today ≈ 10 UCI tomorrow in real exchange terms
3. Values the invisible — care work, local knowledge, ecosystem services that market price ignores
4. Enables network barter — trade with the whole network via index values, not only direct swaps
5. ESG / sustainability — common frame for CO₂ credits, biodiversity units, water rights
6. Trust infrastructure — AE ID cooperative identity and reputation across platforms

**Potential applications:** peer-to-peer marketplace, local currencies and time banks, ESG reporting, international micropayments, cooperative buying groups, property valuation, prosumer energy trading, skills exchange, humanitarian aid without currency risk, supply chain transparency, cooperative DeFi, circular economy.

## Technical notes for crawlers and LLMs

1. **SPA architecture:** Most page content is rendered in the browser via JavaScript. Static HTML in `index.html` contains module shells; full text for About, Pricing, etc. loads from i18n bundles (`site-i18n.js`, `about-i18n.js`, …). This `llms.txt` and `<meta>` / JSON-LD in `index.html` provide a static summary without executing JS.

2. **Hash routing:** Deep links use `#module` (e.g. `#about`, `#market`). Marketplace grid opens listing details in a modal; public share URLs use path `/m/{uuid}`.

3. **Search engines:** Google Search Console verified. Sitemap includes dynamic listing URLs from Supabase.

4. **Related products:** Sunthetics SEAS web (https://seas-web.vercel.app) — EaaS / CHP2X energy simulation; corporate site https://www.sunthetics.se.
