### [Spike](https://www.g2.com/es/products/spike/reviews)

Spike es una plataforma de comunicación por correo electrónico y en equipo impulsada por inteligencia artificial que combina correo electrónico, chat, reuniones y herramientas de colaboración en un único espacio de trabajo organizado. Está diseñada para profesionales, pequeños equipos y empresas que utilizan el correo electrónico como su canal principal de comunicación, pero que desean una forma más rápida y simplificada de gestionar las interacciones y tareas diarias. Al transformar el correo electrónico tradicional en un formato similar al chat, Spike simplifica cómo los usuarios leen y responden a los mensajes. La plataforma elimina encabezados repetitivos, texto citado y largas cadenas, permitiendo que las conversaciones aparezcan como hilos limpios y continuos. Los usuarios pueden gestionar todas las cuentas de correo electrónico, calendarios y contactos en un solo lugar mientras aprovechan la inteligencia artificial incorporada para resumir conversaciones, redactar respuestas y organizar la bandeja de entrada automáticamente. Spike es compatible tanto para uso individual como en equipo. Los freelancers y profesionales lo utilizan para gestionar clientes y proyectos de manera más eficiente, mientras que los equipos confían en Spike para centralizar la comunicación, compartir archivos y colaborar en tiempo real sin cambiar entre múltiples herramientas. Características principales: Correo electrónico conversacional: Presenta los correos electrónicos como conversaciones naturales similares a chats, manteniendo la compatibilidad total con los protocolos estándar de correo electrónico. Herramientas de productividad con IA: Proporciona resúmenes automáticos, respuestas sugeridas, traducciones y redacción de contenido para acelerar el flujo de trabajo. Bandeja de entrada prioritaria: Utiliza IA para clasificar los mensajes entrantes en categorías relevantes—Prioridad, Otros, Notas y Destacados—ayudando a los usuarios a centrarse en lo que más importa. Reuniones integradas: Permite realizar llamadas de voz y video directamente desde los hilos de correo electrónico para una coordinación más rápida. Notas y documentos colaborativos: Permite a los usuarios crear, editar y compartir documentos en tiempo real dentro de la bandeja de entrada. Bandeja de entrada y búsqueda unificadas: Consolida múltiples cuentas de correo electrónico y calendarios en una sola interfaz con búsqueda entre cuentas. Bandeja de entrada compartida: Ayuda a los equipos a gestionar las comunicaciones con clientes y proyectos de manera colaborativa, asegurando tiempos de respuesta más rápidos. Compatibilidad: Funciona con Gmail, Outlook, iCloud, Office 365, Yahoo Mail y todas las cuentas compatibles con IMAP en plataformas de escritorio, móviles y web. Seguridad y privacidad: Spike está libre de anuncios y nunca vende o monetiza los datos de los usuarios. Todos los datos de los mensajes están encriptados utilizando el estándar AES-256. Spike es adecuado para usuarios que buscan una plataforma de comunicación unificada que mejore la productividad mientras mantiene la familiaridad del correo electrónico. Puentea la brecha entre los clientes de correo electrónico tradicionales y las herramientas de colaboración modernas, ofreciendo un único espacio de trabajo mejorado con IA que ayuda a individuos y equipos a mantenerse enfocados y eficientes.

Audio conferencing applications connect disparate parties of a conversation through a hosted voice connection. It has the capacity to perform small group calls but is more commonly used to facilitate meetings and other professional communications. It is also a good tool for massive communication and can host conversations between multiple, large parties. Audio Conferencing tools aid companies that employ people in remote or work from home roles, as well as companies communicating from separate locations. They also simplify the process of making international calls by providing localized dial-in numbers, eliminating the need for international phone plans. Audio conferencing solutions often integrate with Web-based solutions, such as Webinar or Web-Conferencing for advanced web-based features such as chat, instant messaging, screen and file share.

To qualify for inclusion in the Audio Conferencing category, a product must:

- Provide audio communication for meetings & Collaboration via PSTN or mobile network
- Be capable of multi-user audio conference calls on an audio conferencing bridge
