24 alternatives to LegendKeeper, collaborative maps and notes for game-masters
As a result of the industry I work in (TTRPGs), sometimes I get to do really fun things. Fun things like: Lock myself in a room with a copy of Calendrical Calculations and make a custom timeline maker for fantasy turbo-nerds like myself. Events are represented as integer minutes since the epoch (0, in this case). Then we use a calendar definition to parse those minutes into readable dates, based on the calendar. This allows us to plot events on a big zoomy Gantt timeline, as well as a standard list and calendar view. There's still a few things I want to add: Moon tracking for the calendar…

I've been working on markwhen for a bit as a way to create timelines and calendars from plain text, like markdown. I personally like tools that let you immediately start using them, and I set out to do that here with markwhen. Let me know if you have any questions or feedback!

Hey Hacker News! To test implementing AI (and paywalls tbh) in software for the first time, I made this simple calendar creator (no mail address required) that lets a person create a calendar based on his needs and availability and export it to his calendar app, pdf or receive a daily newsletter with his daily tasks (and more). After wrestling with different models (f.e. with huggingface) and encountering different problems, I decided to use ChatGPT's models, tune them a little and see how the result works out. ChatGPT's low price enables me to give users the opportunity to create calendars…

Hi everyone! Want to share something I'm working on. Here is the brief description: From a single text prompt, craft dynamic worlds (both fictional and real-life, of any kind) filled with interacting NPCs pursuing goals, and control (human-in-the-loop) their behaviour and world state in real-time. Text-to-image to visualise every single step of change in the world's and NPC's state. My main goal was to check if it's possible to use LLMs (GPT-4 currently) to make characters interact with each other but in the end, it ended up with a neat little app where users can interfere with NPC's (and…

Hello HN! I got pretty overwhelmed with Notion, Trello, etc. (Even though they are great tools!) as an indie dev, so I built an app that is simpler to use and perfectly suited for an indie like me :) You can basically divide your projects into multiple milestones (a milestone could be e.g. a new version), and the milestones can have multiple tasks that are either todo, in progress, or done. The progress for each milestone is calculated with those tasks, and you can also prioritize and categorize the tasks using tags (E.g. for me, #ph turns into "High Priority", and #pm into "Medium…

Hi HN, I’ve been working on a tool called AI Timeline Maker (https://timeline-maker.org) to solve a workflow problem I kept running into. Creating timelines for project roadmaps, research, or historical topics is usually very manual. Most tools require adding events one by one, which becomes slow when working with long documents or structured content. The idea behind this tool is simple: Instead of starting from a blank canvas, you start with content. You can input text or upload a document, and the AI generates a structured timeline draft automatically. After that, everything is…
