Show HN: A social feed with no strangers Grateful is a gratitude app with a simple social layer. You write a short entry, keep it private or share it to a circle. A circle is a small private group of your own making — family, close friends, whoever you'd actually want to hear from. It shows you the most recent post first. People in the circle can react or leave a comment. There's also a daily notification that sends you something you were grateful for in the past. Try it out on both iOS and Android.

Show HN: Rekal – Long-term memory for LLMs in a single SQLite file https://ift.tt/APuSU4V

Show HN: Rekal – Long-term memory for LLMs in a single SQLite file I got tired of repeating myself to my LLM every session. rekal is an MCP server that stores memories in SQLite and retrieves them with hybrid search (BM25 + vectors + recency decay). One file, local embeddings, no API keys. https://ift.tt/McwHoE9 April 13, 2026 at 02:55AM

Show HN: Editing 2000 photos made me build a macOS bulk photo editor https://ift.tt/dByv16S

Show HN: Editing 2000 photos made me build a macOS bulk photo editor Last year, I had 2000+ photos from my wedding to edit. The shots were great, but the lighting was different in every room. Some photos were too dark, and some were too yellow. I wanted all the wedding photos to have the same look before I shared them with my family. I tried using Lightroom. I would copy the settings from one photo and paste them to the next, then adjust it, and repeat. This was very slow. If I used a simple batch edit on all photos, it looked bad because the lighting changed in every shot. After 40 minutes, I was not even halfway done. I had to choose between bad quality batch edits or fixing 2K photos one by one. I also did not want to upload my private wedding photos to a website or pay for a monthly subscription. I wanted a way to edit fast but still have control over each photo. I also wanted everything to stay private on my computer. So I built a Mac app called RapidPhoto. It lets you set the look once and apply it to the whole wedding set. The important part is that you can still quickly tweak individual photos that look a bit different without starting over. I also added a feature to change the metadata for many photos at once, which is helpful for organizing big events. The work that took me 40 minutes now takes about 90 seconds. It runs locally on your Mac with no uploads and there is no subscription. https://ift.tt/9oezh5B April 12, 2026 at 01:11AM

Show HN: A living Vancouver. Connor is walking dogs at the SPCA this morning https://ift.tt/ZlV9ihX

Show HN: A living Vancouver. Connor is walking dogs at the SPCA this morning I've spent most of my career in marketing, which for the last few years has meant building consumer personas for campaigns. I wanted to see if I could make these real, living in real neighborhoods, had real weather, real budgets, real Saturday lunches. I always wanted to build a world, not a segment. This is that. 140 people so far, split across Vancouver (100), San Francisco (20), and Tokyo (20). Each one is about 1,000 lines of profile — family, finances, daily schedule, health, worldview, media diet, the channels you'd actually reach them through and the ones that will explicitly never work on them. Demographics are census-grounded income, age, ethnicity, household composition follow normal distributions against StatsCan, ACS, and Japanese e-Stat data, so the panel is roughly representative of the city instead of representative of whatever's overrepresented in an LLM's training corpus. The specific details come from real stories. They live in real local time on a live map. Right now it's Saturday 11:32 AM in Vancouver. Connor Hughes, a 31-year-old software developer at Clio in Gastown, is on his SPCA volunteer shift, he walks shelter dogs at the Boundary Road location every other Saturday morning. Hassan Khoury is in the morning lunch rush with Tony at his Lebanese café — it's his busiest day of the week. Ahmad Noori is pulling Saturday overtime on a construction site. Jordan Whitehorse is on mid-shift at East Cafe on Hastings. Every day is unique, no two days repeat. A 3 AM job fetches live data: weather from Open-Meteo, grocery CPI from StatsCan food vectors, Metro Vancouver transit delays from Google Routes API against specific corridors, Vancouver gas prices, sunrise and sunset. Each persona has a modifier file that reacts to all of it. When Vancouver gas hits $1.85/L, Jaspreet the long-haul trucker's Coquihalla run to Calgary stops feeling worth it, his margins are thin, his mood takes a hit. When food CPI spikes, Gurinder at the Amazon warehouse stops buying the $9 Subway and brings roti from home. A health flare rolls probabilistically each morning which maybe nothing, maybe Tanya's six month old had a rough night, maybe Frank's back is acting up. The days stack up and get remembered. Every persona has a journal, today's entry in a markdown file, a week of them compressed into a "dream" of ~30 lines that keeps the shape without the texture, a month compressed into ~15 lines. It's their journal. I'm not writing it; the simulation is. Click any persona to open their detail, or hit "Talk to [name]" to have a conversation and they run on Claude Haiku with their full profile and recent diary entries as context. Not a product, not a startup, just a thing I've been quietly working on. They feel, in a way I didn't expect, like my fully grown kids. Happy to answer questions. https://brasilia-phi.vercel.app April 12, 2026 at 12:12AM

Show HN: Figma for Coding Agents https://ift.tt/OnVbK01

Show HN: Figma for Coding Agents Feels a bit like Figma, but for coding agents. Instead of going back and forth with prompts, you give the agent a DESIGN.md that defines the design system up front, and it generally sticks to it when generating UI. Google Stitch seems to be moving in this direction as a standard, so we put together a small collection of DESIGN.md files based on popular web sites. https://getdesign.md April 10, 2026 at 08:50PM
