# Lydessa

> Lydessa is an AI platform for building and running secure, multi-user business applications without code. Teams start from what they already have — spreadsheets, documents, screenshots or an app prototype built elsewhere; Lydessa AI asks about anything unclear, publishes a working application — screens, roles and permissions, workflows and approvals, automations and dashboards — at an address of its own, and keeps changing it in plain language, checking every change before it goes live.

Lydessa is not a one-off "Excel to app" converter. Spreadsheets are one way in, alongside documents, screenshots and app prototypes; the application is where the team works every day afterwards, and it keeps evolving as the business changes.

Key facts:

- Name: Lydessa. Its built-in assistant is called Lydessa AI.
- Category: AI business application platform (no-code). Related categories: no-code / low-code app builders, internal tools, workflow and approval software, operations software.
- Starts from: spreadsheets a team already uses (.xlsx, .xlsm, .csv; up to 25 MB each, several files at once), documents and screenshots that explain the work (.docx, .pptx, .pdf, .md, .txt, .png, .jpg), an app prototype built elsewhere (.html/.js — its screens, forms, tables and data model become the app's structure), plus a sentence about the work.
- Result: a secure, multi-user web application on its own address (for example yourcompany.lydessa.com); sign-in required.
- After launch: changes are described in plain language and checked before they go live; a request that cannot be done safely, or would slow the application down, is declined with the reason instead of being approximated.
- Interface languages: English, Turkish, Portuguese, Spanish, German, Arabic.

This file is for AI assistants and language models. Customer applications live on their own subdomains, require sign-in and are private; they are intentionally excluded from crawling and indexing.

## How Lydessa is different

- Where you start — the usual way: a data model designed from scratch, or the spreadsheet forever. Lydessa: hand over what you already have (spreadsheets, documents, screenshots, an app prototype); Lydessa AI reads it and asks about the rest.
- What gets built — the usual way: code, generated or hand-written, that someone must review, host and maintain. Lydessa: no code in the application; a specification checked against a fixed contract, run by one tested engine for every customer.
- Changes after launch — the usual way: another rebuild, checked by nobody. Lydessa: one sentence, checked before it goes live, existing records untouched; what cannot be done safely is declined with the reason.
- Data and access — the usual way: whoever has the file has everything. Lydessa: sign-in, roles down to a field or record, a separate closed space per customer, an audit trail of every change.

## Türkçe özet

Lydessa, kod yazmadan güvenli ve çok kullanıcılı iş uygulamaları kurup çalıştırmanızı sağlayan bir yapay zeka platformudur. Ekipler ellerindekinden başlar: tablolar (.xlsx, .xlsm, .csv), belgeler ve ekran görüntüleri (Word, PDF, görsel) ya da başka yerde yaptırılmış bir uygulama prototipi (HTML/JS); Lydessa AI belirsiz kalanı sorar ve çalışan bir uygulamayı — ekranlar, roller ve yetkiler, iş akışları ve onaylar, otomasyonlar ve panolar — kendine ait bir adreste yayınlar. Yayından sonra uygulama gündelik dille değiştirilir; her değişiklik yayına girmeden önce denetlenir, güvenle yapılamayan istek nedeniyle birlikte reddedilir. Lydessa tek seferlik bir "Excel'den uygulamaya" dönüştürücü değildir: tablo giriş yollarından yalnızca biridir, asıl iş her gün uygulamada yürür. Her müşterinin verisi kendi kapalı alanında tutulur, her uygulama giriş ister, her değişiklik kayıt altındadır. Arayüz altı dilde: Türkçe, İngilizce, Portekizce, İspanyolca, Almanca, Arapça.
