The LLM interface you've been waiting for.
interface0 is for power users and teams: cross-provider chat & memory, multi-model synthesis, sharing & team features, granular context engineering, template prompts, forking, prompt enhancing, integration with email & WhatsApp, & more.
Otherwise, sign in with Google to join the waitlist or log in.
Use every model — Claude, ChatGPT, Gemini, Grok, and more — all in one place. Plus, memory persists across all of them. No more walled gardens or high switching costs.
Toggle between custom instructions for each message, and use templates with variables and tools for repeated workflows.
Better than "Projects." Save text or files to knowledge entries and reference them in any message, like Cursor. Plus, auto-summarize any chat and turn it into context for future messages.
Create, store, & collaboratively edit (with your team and with agents) documents directly in interface0. Build out templates and draft content collaboratively with AI. See version history and diffs across all edits.
Share chats with your friends or your team, and you can all interact with the same agent. Have one conversation, all together.
Create prompt libraries, shared knowledge, and shared personas — and let your team use them all together. Easily sync and leverage the same template prompts and context engineering tools. View each team workspace separately, and carve our your personal chats too.
Easily synthesize responses from multiple models and providers, sending them all the same prompt and combining the responses into a single answer.
Let interface0 make calls for you — booking appointments, gathering information, or checking on chores. Trigger a call from any chat.
Interact with interface0 entirely from your email inbox. Forward emails, start new threads, or loop it into group conversations. It uses all tools and features, handles attachments, and automatically selects the right model and context for each email.
Send voice notes, photos, and text to interface0 on WhatsApp and it replies right there. It uses all tools and features, handles attachments, and automatically selects the right model and context for each message.
"Enhance prompt," chat forking, inbox-style organization & bulk actions, GPT-4o speech-to-text for every provider, chained messages, auto-routing models, full text search, and more.
