    Jatter.ai

    Jatter is an AI-powered chat app that keeps every conversation secure and anonymous through client-side encryption, ensuring only you hold the key to read your messages and that the service never retains your chat history. It anonymizes chats by stripping personal identifiers before processing, lets you draft emails, documents, or notes quickly while maintaining full encryption, and provides detailed, personalized answers across technical or creative topics to help you learn faster. When you mention places, Jatter auto-links them to maps for easy trip planning and restaurant or attraction recommendations, and it supports end-to-end encrypted location sharing so you can securely share your whereabouts with friends or collaborators. Built on GPT-4o Mini with integrated maps functionality, Jatter combines robust privacy protections with versatile chat features for private, intelligent conversations.

    Lumo is a privacy-first AI assistant built to deliver the power of generative AI while keeping your conversations completely confidential.

You can ask Lumo anything, from summarizing documents and rewriting emails to coding assistance, translations, brainstorming, and more, without any risk of your data being used to train models or shared with third parties.

Available without signup and deployable via web or mobile apps, Lumo offers both free and plus plans.
