About

Lumo is a privacy-first AI assistant built to deliver the power of generative AI while keeping your conversations completely confidential. Developed by the privacy experts behind Proton Mail and VPN, Lumo ensures that your dialogues remain yours alone, no logs are stored on the server side, and all saved chats are encrypted with zero-access encryption, meaning even Proton cannot read them. Open source by design, the service is transparent and verifiable. 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. Conversations are encrypted end-to-end, and even the AI’s web search capability (if enabled) runs through privacy-friendly engines. Available without signup and deployable via web or mobile apps, Lumo offers both free and plus plans.

About

SecuredAI is a privacy-first AI assistant that protects sensitive information before it is sent to large language models such as OpenAI and DeepSeek. The platform automatically detects personally identifiable information (PII) and other sensitive data, replaces it with context-preserving placeholders, and restores the original values locally on the user's device after the AI generates a response. Its Zero-Knowledge Vault ensures that sensitive information never leaves the device and that encryption keys are never stored on SecuredAI's servers. The platform supports detection of names, email addresses, phone numbers, organization names, account numbers, identifiers, and custom data patterns. SecuredAI is designed to help organizations adopt AI safely without exposing confidential business, legal, financial, or healthcare information.

Pros & Cons from Real Users

Pros

  • Easy to use and ask questions. Answers are easy to understand, helpful and on target. Totally PRIVATE, they are NOT earning money by selling my data - thus I pay for it.

Cons

  • None found yet. Been using only a couple of months - but had tried ChatGPT, and CoPilot before.
