Sinapsis IA ejecuta modelos de lenguaje (LLM) directamente en tu iPhone, iPad o Mac. Sin nube, sin cuentas, sin suscripción: descargás un modelo, conversás, y todo lo que escribís, adjuntás o generás se queda en tu dispositivo. CHAT CON MODELOS LOCALES • Catálogo curado de 16 modelos abiertos (Qwen3.5, Gemma 4, Llama 3.2, Ministral 3, Phi-4, LFM2.5, SmolLM) listos para descargar, con su tamaño real y la memoria que necesitan. • Respuestas en streaming, varias conversaciones guardadas, instrucciones del sistema, regenerar y detener. • Los modelos que razonan muestran su pensamiento en un bloque plegable. • Estadísticas por respuesta: tokens por segundo y tiempo hasta el primer token. ADJUNTÁ LO QUE QUIERAS • Fotos y capturas: los modelos con visión (Qwen3.5, Gemma 4, Ministral 3) describen y analizan imágenes. • Documentos: PDF, texto, código, JSON, CSV… el contenido se le pasa al modelo para resumir, buscar o responder preguntas. • Audios: se transcriben en el dispositivo con el reconocimiento de voz de Apple y el modelo responde sobre lo dicho. SERVIDOR LOCAL • API compatible con OpenAI (/v1/chat/completions), como LM Studio, para usar el modelo desde otras apps o desde tu computadora en la misma red Wi-Fi. TODO EN TU DISPOSITIVO • Funciona sin conexión una vez descargado el modelo. • Sinapsis IA no recopila datos, no tiene publicidad ni rastreadores. Las conversaciones nunca salen del dispositivo. • GPU (Metal) en iPhone, iPad y Mac; parámetros de muestreo, contexto e hilos ajustables. • Modo claro y oscuro; interfaz en 10 idiomas. VERSIÓN GRATUITA Y PRO La versión gratuita incluye cinco modelos pequeños para siempre, sin límites de uso. Sinapsis IA Pro es una compra única (sin suscripción) que desbloquea todo el catálogo, la búsqueda de cualquier modelo GGUF en Hugging Face y la importación de tus propios modelos. Los modelos son de código abierto y cada uno tiene su propia licencia, indicada en su ficha. Necesitás un dispositivo con al menos 4 GB de RAM; los modelos grandes requieren iPhone Pro, iPad Pro o Mac.
