Yes, privacy is Marv’s top priority. Marv uses industrial-grade privacy standards, meaning your data stays secure, is never used for training models or shared with anyone. Plus, if you ever want to say goodbye, just opt out, and Marv will “forget” everything, leaving no trace behind.

Marv is powered by the ChatGPT 4o mini for basic tasks and 4o for more complex ones. He always uses the most recent frontier model from OpenAI so you can be assured that as these models improve, Marv will get better and smarter. His knowledge base is unlimited since he also has access to the web and can search for current information. Marv uses tools and can analyze images using the newest vision APIs.

Marv’s personas are specialized characters that adapt to different tasks. Tag a persona into your chat using it's @name. Got a question about sports? Chat with @marvdogg for the latest on MLB, NBA, or NFL (cricket is joining the lineup soon!). Your messages are automatically added to the main thread, so Marv retains context even when you get specialized knowledge / answers. New personas pop up all the time—jump into our Discord to stay updated or suggest new ideas!

Yes! Marv uses memory to keep track of your preferences and understand you better over time. He will remember what you like and adjust his responses, avoiding repetitive questions and learning when your tastes change. Thanks to a tree-based knowledge graph, Marv minimizes errors and “hallucinations,” keeping his advice relevant and sharp.

You bet. Text your vision, and Marv will bring it to life with AI-generated images tailored to your description. He’s got a knack for filling in the finer details to deliver something unique and on point. For images, we are currently using Flux from Black Forest Labs since it is the greatest. And if you want even more control, you can submit prompts directly to the @dalle, @flux, or @midjourney personas without juggling apps or browsers.

Marv is based on a large language model. These models predict the best response given a conversation, but can make mistakes. We do our best to deliver high quality information using grounding techniques, but you should double check any important information.

You can request reminders and future texts, but Marv will not message you unless you have requested it.

Yes! Marv works entirely via text messages so this will work on any phone and you can take him with you when you get a new one.

Access to Marv is available for a fixed monthly cost of $15.99 USD. This gives you full access to all models and features including ChatGPT, flux image generation, vision and scheduled messages, and any new features. We occasionally will offer discounts and you can find those codes on the discord server.

Marv goes beyond text. Send him a photo, and he can analyze it for you. Need help identifying a plant, translating text from an image, or spotting animals? Marv’s got it covered. Or, if you’re in the mood for laughs, ask Marv to roast your selfie—he’s got a playful side too!

We’re constantly adding fresh personas to keep things exciting. Head over to our Discord community to learn about the latest personas, get tips, or even suggest one of your own. Marv is as flexible as you need him to be!

We are proud of how fully featured Marv is now, but if there is something you would love to see added, join the discussion on discord and request it to shape the roadmap for new features in real time. This is exactly how @tinylogo (a beautiful way to get a high quality logo done immediately) and @marvdogg (our resident sports expert) came into existence. We love building new functionality into Marv and can't wait to hear what you have in mind.
