Expanse is an intuitive platform designed to make working with AI as simple and productive as possible. You can seamlessly chat with multiple LLMs, all while generating, saving and organising Roles and Prompts to ensure you get the best AI responses every time.

Who is working on Expanse?

We’re a tight-knit team of artists and engineers on a mission to build a future of AI-powered work that’s both accessible and delightful.

Features

What AI models are available to use?

Expanse gives access to a range of LLMs and image generators. You can view the full list on our LLM Directory

Why isn’t there a web app?

While in Closed Beta, we've intentionally designed our product as a desktop application rather than a web app to prioritize security and privacy. This approach offers two key advantages: it helps protect against bot exploitation, and it ensures all your data remains stored locally on your device only- never on our servers. We understand that this reduces some accessibility, however, a web app is likely to be released shortly after our public launch.

What File Types are supported?

In Expanse you can attach files to LLMs with Vision.

Supported file attachment types

We will continue to grow the types of files you can attach. If there is a specific file type you would like us to support, please let us know!

Does Expanse have memory?

Unlike most LLMs which save all messages to a central memory, Expanse holds memory for each thread; this takes up less data, reduces any misuse of context and also allows the app to run lighter and faster on more devices. We also have a Chat/Focus mode which allows you to toggle the Thread’s memory on/off. This is especially useful to reduce LLMs becoming confused by too much context and hallucinating (creating responses that are not factually correct).

What are the top feature requests?

At Expanse, we prioritise user feedback to inform our product roadmap. You can check out our top feature requests via our Community Discord.

Security & Privacy

Is my data secure?

At Expanse, we don’t store or train on any of your data (the only data we keep is your email) and we have a commercial API for all our LLMs ensuring they don’t store your data either. See our full privacy policy below.

Can I sync my account across multiple devices?

Since Expanse does not store your data, there is currently no way to sync your account’s spaces, roles or prompts across different devices. We know this can be less convenient and will include the ability to sync accounts when our web app is released later this year.
