Features ​

Sapien Chat ​

SapienAI provides a chat interface similar in function to ChatGPT, Claude or other genAI interfaces. You can converse with the AI models, upload images and files, and more. However, Sapien's chat experience ticks a few boxes not found in other options.

• GPT4, o3, Claude 4, Google Gemini 2.5 Pro & Ollama: One interface to access the top publicly available generative AI models or your own self-hosted ones! You can choose which model powers a chat, including changing models mid-chat to take advantage of the different capabilities of each model.
• Realtime audio chat: Have a realtime conversation with SapienAI.
• All data is stored locally on your device: Everything fed into the app, including all messages (sent and received), images (uploaded and generated) and files, remains stored on your device.
• Model hosting flexibility. Models can be accessed directly from OpenAI, Anthropic or Google, or you can connect to these models through Azure, AWS or Google Vertex. With Ollama support, you can also now run models locally on your machine, or connect to services that utilise the same Ollama API format.
• All responses backed by actual academic papers. Reduce the risk of hallucination, improve model accuracy and have direct access to academic papers. SapienAI can undertake a search for relevant academic papers to inform each response.
• Academic focused: SapienAI is prompted to act as a non-biased and highly-intelligent academic advisor. You could think of SapienAI as a highly knowledgeable expert in all domains. With cross-chat memory and the ability to provide customised instructions SapienAI is flexible and always tailored to your needs.
• Semantic search: All uploaded documents are stored and semantically indexed, allowing you to search for content using natural language. Bonus: If you have connected your Zotero account, you can semantically search items stored there as well!

Research Spaces ​

Write your next paper with SapienAI's Research Spaces. Research Spaces are dedicated workspaces for you to upload your project documents and files. An integrated editor allows you to write and edit documents, and the chat interface allows you to ask questions about your documents, summarise them, and more. All uploaded documents are summarised based on the instructions you provide and are semantically indexed, allowing you to easily find information.

• Streamline your writing: Our integrated editor lets you write with as little or as much AI assistance as you desire. Keep it simple and write using Markdown or other text-based formats, or leverage our integrated support for Typst and LaTex for a richer writing experience.
• Organise your research: Keep all your notes, sources, and drafts in one intelligent, interconnected space. All uploaded documents can be semantically searched, and AI-powered literature reviews can be exported in Word and Excel format.
