Overview
Chorus is a Mac desktop app for using multiple AI models in one place. Its homepage describes it as a fast, lightweight interface for chatting with models such as o3, Claude, Gemini, DeepSeek, and local open-source options.
The product is organized around a unified chat workflow rather than a single-model assistant. Public pages highlight URL and PDF parsing, full-text search, custom prompts, and support for bringing your own key, with pricing that includes a free Hobby plan and paid Plus and Frontier plans.
Features
Side-by-side model access
Use the app to compare answers from different models in the same conversation flow. The product positioning emphasizes having several models available at once.
URL and PDF parsing
Work with links and documents through URL parsing and PDF parsing. These capabilities help bring source material into the conversation instead of only prompting from memory.
Full-text search
Search across prior conversation content with full-text search. That makes it easier to revisit earlier prompts and responses.
Custom prompts
Create reusable prompts with custom prompts support. This is useful for recurring workflows and more consistent prompting.
Bring-your-own-key access
Bring your own key on the free Hobby plan and use Chorus with supported model access from your own accounts. The pricing page also notes open-source status.
Use cases
Model comparison
Compare outputs from several models in one session when you want different perspectives on the same prompt. Chorus is built to keep those responses in a unified chat flow.
Reading source material
Bring URLs or PDFs into the conversation when you want to discuss source material rather than paste excerpts manually. The site specifically calls out URL and PDF parsing.
Repeatable prompting
Reuse prompt patterns for recurring tasks by saving or applying custom prompts. This is useful when you want a consistent structure across repeated chats.
Retrieving past context
Search through prior chats or responses to find earlier context quickly. Full-text search makes the app more practical for ongoing work across multiple sessions.
Testing and light usage
Use a free or bring-your-own-key setup if you want to try the app without immediately committing to a paid subscription. The Hobby plan is described this way on the pricing page.
