24 alternatives to A Notion-like platform for building interactive models

Hey HN. I wanted to share an update to our previous thread, “Notion with problem solving capabilities”. The Decipad public beta is now live. You can try it for free here. https://www.decipad.com/ We started building Decipad to make numbers more expressive and playful. It’s a notebook environment where you can combine text, numbers, data and calculations into a story. Our goal is to help people communicate with numbers more effectively and collaborate across diverse backgrounds. It’s feels a bit like Notion, but it’s for building interactive models and reports. A few things…

Decipad is a notebook platform for creating interactive models and reports by combining text, numbers, data, and calculations into narratives.

    Hi, I'm a high school teacher from Australia and I've built what I'd like to think is a pretty nifty ChatGPT powered presentation tool for teachers. I'd love it if you could have a look at it and give me some of your feedback. I don't think there's much overlap with the HN crowd and school teachers, but I've been coming here for many years and thought I'd post here and see what you all think. Check it out if you have a minute and I'd be super happy to hear your feedback too. https://www.slidehero.ai/ You can jump in and have a play with the tool all you like ;) Cheers, Eli

    ThinkPost is an Interactive split-panel diagramming, draggable block-based note-taking, and brainstorming tool. I developed ThinkPost as a side project for few months now. Basic idea is parallel streaming of ideas. It's a desktop web app with a very scaled down mobile version just for support. Whole my career I had been working with startups and specifically early stage ones, and it's a big responsibility to devise a feature on our own, think deeply about it in different streams (logically, security, re-usability, platform APIs etc.) and even present distilled part of it to stakeholders…

    Just finished my second year at college studying Computer Science, and wanted to try and gain experience as a full stack dev this summer, so I made a website that allows users to create stories using openai's API, using embeddings for custom terms users can define, and create short stories and chapters alike. I'm mainly just looking for some feedback on how I can improve it or make it more presentable, so any help/feedback is welcome and appreciated!

    I got the idea of [mindmap.so](http://mindmap.so/) out of my own frustration of managing my personal notes in Notion and Miro in parallel. I have built it 3 months back on top of excalidraw, posted it in Reddit a couple of times, and never looked back (was using it only for personal use). Little did I know that the small and nimble tool that I created has crossed 2000+ users (was so surprised when I saw the dashboard last week). It was all organic and word of mouth . Having 2000+ users trusting a product is no easy feat. That’s when I thought may be I should put some more…

    Hello HN, My name is Deepak. I've created this platform (https://stackcrunch.io) where developers can share their experiences in form of short stories linked to real-world practical solutions on Q&A platforms. This project is currently in early access mode, where you can check out the platform & start writing your stories. Also, please do check out the launch article and how to create a story at https://stackcrunch.io/posts I'd love to hear back from the community. Warm Regards, Deepak

    Hi HN, Rohan and Michael here from Decipher (https://getdecipher.com/). We’re excited to introduce AI-generated session summaries and open source the pipeline. It processes raw rrweb events to produce plain English summaries of what happened leading up to and around an error. You can find the code here: https://github.com/decipherai/session-replay-analyzer We created Decipher because we were frustrated with noisy alerts, time-consuming error triaging, and customer churn due to bugs and session replay analysis is a powerful step forward. Here’s an…

    Solo dev here. Built a platform where people write short story segments starting with "Imagine if..." and others continue. AI generates an image for each part, stories branch based on community votes. Stack: React Native/Expo, FastAPI, MariaDB, FLUX-dev via Replicate, Groq for text. Curious what you think — especially about the cold start problem with collaborative platforms.

    Hi HN! BlockNote (demo @ https://blocknote-main.vercel.app) is my shot at creating an extensible, block-based editor (similar to Notion, Coda, etc.). Featuring different block types, animations (try changing block types, indenting, etc), menus, placeholders, collaboration and more you expect from a good editor. I'm on a journey to build a decentralized, live-programmeable and collaborative block-based editor [1] that syncs over Matrix [2], and unfortunately found that there's still not a great Open Source text editor component on par with something Notion's editor, which is why I…

    I built a mindmap-based discussion platform, but what made the project truly interesting was not the UI — it was building the backend in Common Lisp. Inspired by Paul Graham and his book The Hacker and the Painter, I wanted to experience what it feels like to design a system in a language built for abstraction rather than convention. Instead of relying on a large framework, I combined small libraries and built a minimal internal structure myself.

    Hey HN - my name is Tim and I created Slatebox. Slatebox is a visualization collaboration platform that lets you create editable mind-maps, diagrams, SWOT Analyses (w 100s of other templates) and more -- all based on natural language through AI. It's like Miro but with AI superpowers. Would love to know what you think. I'll be releasing a team pro version soon where teams can auto-diagram their internal ecosystem, including code repositories.
