Threads is Euryka's AI chat surface. Each thread is a persistent conversation with an AI model — scoped to your workspace, optionally tied to a brand and project, and shareable with teammates.
Ways to start a new thread
- Sidebar — click Threads in the left sidebar. A new thread opens automatically.
- Quick Start — type a prompt on the Dashboard and click Create. Euryka creates a thread with your message and files already loaded.
- Quick Actions — click the Thread card on the Dashboard to open a new blank thread.
- Command palette — press Cmd + E (or Ctrl + E), type "threads", and select Create new thread.
Sending your first message
Type in the message input at the bottom of the thread. You can:
- Write a plain text prompt
- Attach files (see file types supported)
- Pick a model before sending
Press Enter (or click the send button) to submit.
Choosing a model
Click the model picker above the message input to select which AI model should respond. Available models depend on your plan:
| Plan | Models available |
|---|---|
| Essential | Gemini, Claude (Anthropic), GPT (OpenAI), Llama (Meta), Mistral, DeepSeek, Grok, Moonshot |
| Pro | Everything in Essential, plus thinking models from Gemini, OpenAI, Anthropic, DeepSeek, Grok, and Moonshot |
| Studio | Everything in Pro, plus Claude Opus and Claude Opus thinking, plus priority access to new models as they launch |
| Enterprise | Everything in Studio, plus priority access to all new models |
You can switch models between messages — the conversation history carries over.
File attachments
Threads accept files alongside your messages. Supported file types:
- Documents: PDF, DOCX, TXT, MD, JSON — embedded automatically so the AI can answer questions about them
- Audio: MP3, OGG, WAV, M4A, AAC — transcribed automatically
- Images: JPG, JPEG, PNG — attached directly for multimodal models
- Spreadsheets and presentations
Maximum 25 MB per file. Maximum 5 files per message (when using Quick Start; standard thread messages may vary).
Adding brand and project context
Use the brand and project picker in the thread input to scope the conversation. The AI is then aware of your brand's guidelines and voice, and the thread is organised under the right project in Brand Hub.
