After long months of work, we are ecstatic to share our vision for the future of email and work communication. Try here: demo.define.app I’d genuinely love to hear what you think, especially if you use email for work! Note: this is a frontend demo with mock data. PS - Reposting this because the previous video included sensitive mock data.

This is what happens when you spend countless hours obsessing over details.

We had so much fun with the holo effect 🃏 Apply for early access to get your own card

Huge respect for GPT-5.6 Sol, but this is on another level.

The `/human-taste` skill is crazy good...

We are *still* cooking 👨‍🍳

Organize your emails easily.

Attachments in define Preview any email attachment by pressing space. There’s also a dedicated Files tab where you can see and search all files from that thread. Try it here: demo.define.app

Product experience starts before login. Our early users aren’t just users.. They’re our first believers. When you request early access, you get your own virtual 3D card. A shareable proof that you were here before the doors opened. Get yours here: define.app

Flexibility is a feature Give users the choice between Focus Mode and Chaos Mode. Productivity isn’t one-size-fits-all. Give users control over how their workspace feels. Try it: define.app

Inbox details 💅

Our email composer speaks markdown • type `#` space → heading • type `-` space → bullet list • type `[]` space → to-do with checkbox • type `>` space → blockquote • type `---` → divider • paste markdown → auto-converts to rich blocks

Email 🤝 block-based editor like Notion /reply → draft a response /auto-improve → improve your block /signature → toggle signature /send → send instantly

Email, but better. • Message bubbles • Files and people in one place • Search across conversations, files, and contacts • A Notion-like editor for email

Email search should be better. How many times have you wasted time trying to find a specific file or message in your inbox? Search at define is multi modal: * keyword search * semantic search (MiniLM-L12-v2 embeddings) * visual search (CLIP ViT-B/32) * federated search across all content types

Drag and drop detail: rotate the ghost while dragging. Moving right → slight clockwise tilt (+2°) Moving left → slight counter-clockwise tilt (-2°) It feels like you're physically holding a card. The rotation gives spatial feedback without being distracting.
