Lumo vs Venice

Lumo

• People who want an assistant that cannot read or reuse their chats
• Proton users who already keep files in Proton Drive
• Trying a private assistant without creating an account

Venice

• People who want chat history kept on their own device
• Trying text, image and video models from many labs in one app
• Developers who want an OpenAI-compatible API for many model types

Lumo

• The free plan limits Max model usage, messages, chat history, image generations and uploads, and allows 1 Project; Proton gives no exact numbers.
• The download menu lists iOS and Android apps and a web app; no desktop app is listed.
• Business use is sold separately, as Lumo Professional or as part of Proton Workspace.

Venice

• The Free plan stops at 10 text and 15 image prompts a day and leaves out document uploads, image understanding and custom system prompts.
• Third-party models run in Anonymized mode: Venice hides your identity, but the provider may still process prompts under its own policies.
• TEE and end-to-end encrypted models need a paid plan, and E2EE mode turns off web search and memory.
• Chat history stays in one browser or device unless you use an encrypted backup or a shared link, and no desktop app is listed.

Lumo

Zero-access encrypted chats

Conversations are stored with zero-access encryption so that only you can read them; Proton says it cannot access them.

No training on your chats

Proton states that conversations are never used to train AI models, to target ads or to build a personal profile.

Web search

Built-in web search brings real-time information into answers. It is included in the free plan.

Files and Proton Drive

Link files and folders from Proton Drive to give Lumo context. The free plan uploads individual small files; Plus allows multiple large files.

Image generation

Turns a description into an image and lets you refine it through follow-up prompts.

Open-source code

Lumo's code is published as open source, which Proton says lets anyone verify that it is private and secure.

Venice

Many models in one app

Text, image, video and audio models from providers such as OpenAI, Google, DeepSeek, Mistral, Meta and Black Forest Labs, plus Claude and Grok models, sit behind one account.

Four privacy modes

Each model shows its mode: Anonymized (identity hidden from the provider), Private (prompts not retained), TEE (run in a secure hardware enclave) or E2EE (encrypted on your device).

Local conversation history

Chats are stored in your browser or on your device, not on Venice's servers. Paid plans add encrypted chat backup and restore.

Image, video and audio generation

Generates, edits and upscales images, and creates video, music and speech with models such as Kling, Runway and Veo. Video and music are paid for with credits.

Web search

Brings current results into answers through Brave with zero data retention or anonymized Google search. Web search is included on the Free plan and is disabled in E2EE mode.

OpenAI-compatible API

One key covers text, image, video, music and speech models, with function calling and web search. API calls are metered in credits, separately from the app's plan limits.
