Show HN: My friend and I built a word game called subletters
My friend and I have been working on this word game as a side project for about six months, and we’re excited to finally share it beyond our family and friends!
The idea came from a simple game my friend used to play with his kids during long car rides — just using their heads and maybe a pencil and paper. He had such fond memories of it that we decided to bring it to life as a proper game.
We’d love for you to try it out and let us know what you think!
PS This is my first real frontend-heavy project, and clean code was not my priority, so I'm sure there is considerable room for improvement on the technical implementation side (don't judge)!

Show HN: Three Kind Words – Spread kindness one mysterious postcard at a time
Ever wish you could anonymously drip-feed kindness through the mail?
I tried answering that with Three Kind Words (https://threekindwords.com), a vending machine that sends three mysterious postcards over three weeks, slowly revealing a message.
Here’s how it works: you pick a three-word message (like "You are awesome" or "I love you"), and each word is printed on its own postcard, mailed one week apart to your unsuspecting recipient. You stay anonymous until the final card arrives, completing the message and revealing who sent it.
I made this because I love getting real mail and wanted a simple, meaningful way to help people feel more connected.
Under the hood, it's built with Cloudflare Workers and a Hugo static frontend hosted on Cloudflare Pages. Payments are processed via Stripe, and postcard printing and delivery are handled through the PostGrid API. Each set of three postcards costs $5 total, postage included. I store only what's essential to fulfill orders (no addresses are shared or sold) and identifying information is wiped 60 days after an order is completed.
Currently, it's available only in the US. I've received requests to expand internationally, but I'm still navigating the logistics, regulations, and costs involved.
My first experience with Hacker News was unexpectedly wild: a blog post I wrote [0] hit the front page in February [1], but my app broke spectacularly due to a caching issue, right in the middle of my kid's birthday party. I wrote about the experience here [2].
Fortunately, everything's running smoothly now! I've processed over 200 postcards already, and seeing them reach people's hands has been incredibly rewarding. Huge thanks to everyone who's tried it and shared their feedback to help iron out early wrinkles. You can learn more about my progress here [3].
Two recent feature additions:
- Mother's Day Button: Effortlessly send a thoughtful Mother's Day greeting with just a few clicks. We'll choose the right words, designs, and timing to ensure arrival by May 11th (don't forget!).
- Display Name Override: Personalize your greeting with nicknames or custom salutations, while still using the recipient’s formal name for postal delivery.
One of my goals with this project is learning how to grow something from nothing. I'd greatly appreciate insights on reaching potential customers, encouraging repeat visits, and spreading the word genuinely. I've started blogging, created a mailing list, and set up social media accounts with some basic SEO, but haven't ventured into paid ads yet. What's worked best for you when building an audience or gaining early traction for a product like this?
As a thank-you to the HN community, here are five coupon codes for a free postcard set (one per person, please):

Show HN: Agent Heroes – Generate, animate and schedule your AI characters
Hi community :)
I love creating pictures and video on socials using things like ChatGPT and Mid-journey and convert it to video on Replicate and Fal.
But I realized it's super time consuming
So I created a AgentHeroes, a repository to train models, generate pictures, video and schedule it on social media.
Not sure if it's something anybody needs so happy for feedback.
Of course a star would be awesome too
*Here is what you can do:*
* Connect different services like Fal, Replicate, ChatGPT, Runway, etc. * Train images based on models you upload or using models that create characters. * Generate images from all the models or use the trained model. * Generate video from the generated image * Schedule it on social media (currently I added only X, but it's modular) * Build agents that can be used with an API or scheduler (soon MCP): * Check reddit posts * Generate a character based on that post * Make it a video * Schedule it on social media
*Everything is fully open-source AGPL-3 :)*
*Some notes:*
Backend is fully custom, no AI was used but the frontend is fully vibe code haha, it took me two weeks to develop it instead of of a few months.
There is a full-working docker so you can easily deploy the project.
*Future Feature:*
* Connect ComfyUI workflow * Use local LLMs * Add MCPs * Add more models * Add more social medias to schedule to
And of course, let me know what else is missing :)

Show HN: FormReach – LLM form marketing automation for Japan
I developed an AI tool that automates contact form submissions for marketing. Simply select target companies from a list, and our LLM automatically fills out and submits forms for you. I created this because user acquisition was always the most time-consuming part of my previous product development and sales efforts. While currently limited to the Japanese market, I hope it can help those doing business in Japan save significant time.
FormReach features: - No initial costs; you're only charged for successful submissions - AI handles all form completions and submissions automatically - Continuously updated database of compatible contact forms
If you're interested in the Japanese market or have feedback on this approach, I'd appreciate your thoughts.

Show HN: Simpleformapp – A lightweight form and table tool for lead capture
Hi HN,
I built Simpleformapp to replace my Jotform + Airtable workflow. I was paying $58/month just to capture and manage leads — it worked, but felt like overkill.
So I made something simpler: - Create clean forms - View/manage submissions in a table - No bloat or complex pricing
It’s live and I use it daily to run my business. Would love any feedback — UX, performance, feature ideas, or thoughts on positioning.
Thanks!
