Show HN: Pinblocks – Your Chats with Notion-Style Collaborative Blocks

https://pinblocks.io/
1•p2hari•10h ago
Hey HN,

Tired of juggling endless chat threads, scattered links, and disjointed tools for group collaboration? I was too—constantly losing track of surveys, to-do lists, and shared notes in the chaos of WhatsApp or Slack. That's why I created Pinblocks (https://pinblocks.io): the ultimate fusion of Notion's powerful canvases with the immediacy of chat. Pin interactive data blocks right to your messages, and watch as anyone, anywhere, collaborates in real-time without ever leaving the conversation. It's seamless, engaging, and a game-changer for teams, families, and communities!

Imagine Notion meets chat: Each pinned "canvas" becomes a dynamic hub holding multiple blocks where users can edit, vote, brainstorm, or play together.

Take my badminton group: We used to spam surveys in WhatsApp, only for them to get drowned by off-topic messages. Now? Pin a survey block—it sticks at the top, tallies responses instantly, and keeps the energy high without clutter.

Or for my kid's birthday bash: I whipped up a canvas with an event block for RSVPs (track who's coming with ease), a to-do list for party prep (assign tasks like "buy cake" or "grab decorations"), a survey for fun activities, and a text block auto-generating daily jokes or quotes to spark laughs and keep the planning group buzzing with excitement.

Why Pinblocks stands out:

easy block creation for instant magic: /todo for collaborative checklists, /survey for polls that evolve with votes, /event for smart scheduling, /table for editable spreadsheets, /text for notes (with auto-generated daily quotes, jokes, or inspirations), or /tictactoe for quick games to break the ice.

AI superpowers: Our built-in AI generates blocks on demand—command "Create a to-do list for project kickoff" or "Pin a hilarious joke of the day," and it's done, boosting engagement and creativity in every group.

Effortless cross-platform sync: Integrates with any chat app that handles pinning or links; real-time changes flow to all collaborators, no apps to download or accounts to juggle.

On the tech side: Built for speed and scalability with a frontend in React (for buttery-smooth UI), TanStack Router (efficient client-side navigation without bloat), and Tailwind CSS (rapid, responsive styling that looks pro out of the box). Backend? Powered by Supabase Oh, and AI played a starring role in development—I tested various models and IDEs to accelerate coding and ideation. Stay tuned for a deep-dive blog post on that journey!

Still in early days, but Pinblocks is already transforming how groups connect and create. Does this ignite ideas for your workflows? I'd love your thoughts on features, UX tweaks, or wild new block ideas. Dive in at https://pinblocks.io and let's build the future of collaborative chatting together!
