Products that do what Pivots and millions later, I built a lambda to start WhatsApp chats does
I've been working on my startup for years to no avail. Raised VC money and burned through millions - now built a simple service that lets you add a "chat to us" button (or can hook to your forms) to launch a WhatsApp chat. The key here is that the button can open chats with different WhatsApp numbers based on rules you can set. These rules can be based on the website visitor's geography, language, time spent on your site or even your business's office hours. Can also hook onto existing forms and use form fields in the rules too. Try it out on our site by clicking the chat to us button and…

Hey Hacker News, I’m excited to share a tiny service that’s very close to my heart - Today Has Been. Here’s how it works: We have a phone number that has WhatsApp Business API enabled. Your messages sent to this number (after you activate your free trial) are added to your journal. It’s a super light weight journaling service - no app download or registration is required. We also send you a daily nudge asking “How did your day go?” and after you have a few posts we send you a random blast from the past. Why I built it: I was an active user and fan of Ohlife - only journalling app that could…

Hi HN – I built an open-source, self-hosted Model Context Protocol (MCP) server for WhatsApp: https://github.com/lharries/whatsapp-mcp It connects to your personal WhatsApp account via the WhatsApp Web multi-device API (using whatsmeow from the Beeper team), and doesn't rely on third-party APIs. All messages are stored locally in SQLite. Nothing is sent to the cloud unless you explicitly allow your LLM to access the data via tools – so you maintain full control and privacy. The MCP server can: - Search your messages, contacts, and groups - Send WhatsApp messages to…

Hello HN! I've been thinking about the idea of a LLM thats a clone of me - instead of generating replies to be a helpful assistant, it generates replies that are exactly like mine. The concept's appeared in fiction numerous times (the talking paintings in Harry Potter that mimic the person painted, the clones in The Prestige), and I think with LLMs, there might actually be a possibility of us doing something like this! I've just released a fork of the facebookresearch/llama-recipes which allows you to fine-tune a Llama model on your personal WhatsApp conversations. This adaptation can…

I connected the WhatsApp and ChatGPT APIs to allow you to connect and speak with ChatGPT over WhatsApp. Have called it ChatsApp. Simply add the number +1 689 267 3467 to your phones contact list, and start chatting with ChatGPT over WhatsApp. Was pretty simple to build. Also had to buy a virtual number online to allow setting up a WhatsApp account with. The WhatsApp servers receive the message from the WhatsApp mobile application, which forward a webhook request to the application server I setup. The request gets forwarded to the ChatGPT API (i.e the OpenAI Chat API), and voila, you are now…
