Hearth: AI Chat & Assistant

Hearth is a calm, warm home for the AI models you actually want to use — with your conversations, your assistants and your notes all in one place. FIVE MODELS, ONE APP Pick the mind that fits the moment, or let Hearth pick for you: • Swift — GPT-4.1, fast and capable, the everyday default • Sage — Claude Sonnet 4.6, for careful reasoning and long documents • Muse — Gemini 3.1 Pro, for creative and long-context work • Plus GPT-4.1 mini and GLM-4.6 under "all models" Switch mid-conversation. The thread comes with you. TALK INSTEAD OF TYPING Tap the microphone in any chat and speak. Hearth records your voice, transcribes it securely on our servers, and drops the text into the composer for you to edit before you send it. Hearth asks for microphone access the first time you use it, and only then. Recordings are used to produce the transcript and are not stored. READ A LINK, GET THE POINT Paste any web page or YouTube link and get a clear summary. No wading through a twenty-minute video for one answer. MAKE PICTURES Describe an image and Hearth draws it. Keep the ones you like in your gallery. ASSISTANTS AND TASKS A library of ready-made assistants — a writing coach, a study partner, a recipe helper — each with its own personality. Or start from a task template and fill in the blanks. Make your own assistants too. MEMORY THAT IS YOURS Hearth can remember what matters to you between conversations, and you can read, edit or erase any of it at any time. Compare two models on the same question side by side. Have a reply read aloud. Keep your own documents in a personal knowledge base and ask questions about them. PRIVATE BY DEFAULT Your conversations are yours. Nothing you write is shared with other users — there is no feed, no profile and no public content in Hearth. Delete a conversation, a document, a memory, or your whole account from inside the app whenever you want. RESPONSES ARE AI-GENERATED Hearth's answers come from AI models and can be wrong. Please check anything that matters. Every reply has a Report control if something is offensive or unsafe — tap it and it reaches us directly.
