Show HN: Reelforge – AI tool for generating TikTok & Reels ad scripts
Text
I built a small AI tool that generates short-form ad scripts for TikTok, Instagram Reels, and YouTube Shorts.
You simply enter a product name, choose the platform, and select a tone.
The system generates a hook, main script, and call-to-action.
Demo https://reelforge-ai1.vercel.app/
Built with Next.js and OpenAI.
Would love feedback from the community.

Show HN: Plexicus now has a free tier
We just launched a free tier for Plexicus.
Previously, it was only available through paid plans, but many individual engineers and small teams wanted to try it without going through sales. So we decided to add a freemium option.
Would love to hear feedback from you guys

Knuth Test Using Claude Sonnet 4.6 Problem 1.1.2
Knuth Tests using Claude Sonnet 4.6 problem 1.1.2
Knuth Art Of Computer Programming V1 p9 ----------------------------------------------------------------------- Algorithm E (Euclid's algorithm). Given two positive integers m and n, find their greatest common divisor, that is, the largest positive integer that evenly divides both m and n.
E1 [Find remained] Divide m by n and r be the remainder. (We will know that 0 <= r < n)
E2 [Is it zero?] If r = 0, the algorithm terminates, n is the answer
E3 [Reduce] Set m = n, then n = r, then go back to step E1 -----------------------------------------------------------------------
Prove that m is always greater than n at the beginning of step E1, except possibly the first time this step occurs.
======================================================================== Claude Sonnet 4.6 ========================================================================
Proof
We want to show that m > n at the start of E1, for every iteration except possibly the first.
First Execution of E1
When E1 is executed the first time, m and n are simply whatever positive integers were given as input. There is no guarantee that m > n, which is why the exception exists. For example, with m = 2166 and n = 6099, we have m < n on the first call.
All Subsequent Executions of E1
After the first execution of E1, we reach E3 only if r ≠ 0 (checked at E2). At E3, the replacements are:
m = n n = r
Then we return to E1. So at the start of the next E1, the new values are:
m_new = n_old and n_new = r_old
From E1, we know r is the remainder when m is divided by n, so by definition:
0 ≤ r < n
Since E3 is only reached when r ≠ 0 (E2 would have terminated otherwise), we tighten this to:
0 < r < n
Therefore:
n_new = r_old < n_old = m_new
Which gives us:
m_new > n_new
Conclusion
After the first iteration, the new m is always the old n, and the new n is always the remainder r, which is strictly less than the old n. Therefore m > n holds at the beginning of every execution of E1 except possibly the first, which is what we wanted to prove. □

Show HN: CardRooms, a Competitive Cardgame Platform
Hey HN,
I want to introduce you to Cardrooms.app : a free, guest-friendly, competitive platform for shithead (with plans to expand into other card games).
I based the main game on shithead because it is the best game that combines strategy, memorization, luck, and complexity. If you're not familiar with the rules there is a play through tutorial as well as documentation on how to play on the app,
It's still a really new project (1.5 weeks old at the time of writing) so I suggest trying it out with friends as its really hard to get an open room. It's great to play with your card game buddies especially when you're separated by distance or have no physical cards on you.
If you decide to make an account, there is a robust ELO system to help you track your performance against other players, with a global ranking system and some ingame cosmetics to reflect your progress through the ranks.
Any feedback is much appreciated. I'd also love to hear any ideas you have for promoting it - Discord servers, Facebook groups etc. Not really sure where the big online communities hang out (apart from here).
If you enjoy it, tell your friends!

Show HN: Openboard – Live public metrics page for open startups
We run an open startup and believe in sharing numbers publicly. But our setup was a mess: metrics lived in Stripe and PostHog, we'd pull them manually, paste into our CMS, and embed that on the site. Every update was a chore. Every number was stale. Openboard connects directly to your data sources and generates a live public metrics page. No CMS middleman, no manual updates. Currently supports Stripe (MRR, churn, active subscribers) and PostHog (visitors, signups, retention). Adding more integrations based on what people actually need. The base version is free — sharing should be frictionless. Paid plans unlock more integrations and custom domains. Would love feedback, especially from founders who already run an open page and know how annoying this problem is. openboard.fyi

Show HN: EV range calculator – range circles and charger map (700 models)
I built EV Mapping to answer the question EV owners actually ask: "Can I get there and back without charging?"
You pick your car, drop a start pin, set your current charge %, and hit Compute Reach. You get two circles — outer for one-way range, inner for round-trip — plus all charging stations within reach as pins. Click any pin to open navigation in Google Maps.
Stack: vanilla JS + Leaflet, no build step, hosted on Vercel. Charger data merges OpenChargeMap and OpenStreetMap Overpass with deduplication. 700+ EV presets across 20+ markets (US, EU, India, China, AU, etc.) synced every 12h via a Python pipeline on GitHub Actions.
The catalog pipeline ingests fueleconomy.gov, afdc.energy.gov, cardekho.com, and greenvehicleguide.gov.au, plus region-native seed files. It has anti-regression guardrails and a canary→stable promotion workflow so bad syncs don't silently ship.
https://ev-mapping.vercel.app Source: https://github.com/novelmartis/ev-mapping
Feedback welcome — especially on range accuracy and charger pin coverage in non-US markets.

Show HN: ABES – a memory architecture for belief revision in AI agents
I’ve been building ABES (Adaptive Belief Ecology System), a memory architecture for AI agents based on the idea that memory should manage belief state over time, not only retrieve prior text.
The system models memory as structured beliefs with explicit state, including confidence, salience, contradiction pressure, lifecycle status, memory tier, evidence balance, lineage, user and session scope, and decay behavior. Beliefs can be reinforced, weakened, contested, updated, mutated, or deprecated as new evidence arrives.
The goal is to support longer-running agents that need to deal with stale information, conflicting information, confidence change, and belief revision, rather than only recalling similar prior content.
Current implementation includes a structured belief model, reinforcement and decay mechanics, contradiction handling, tiered memory behavior, session isolation, API support, Docker support, and testing/evaluation infrastructure.
What has been verified so far in the project’s published tests and evals:
822 passing tests
a 1,000-prompt evaluation with an overall score of 825/1000 (82.5%)
reported category scores of 96.8% episodic memory, 94.4% working memory, and 92.8% semantic memory
a 15-block side-by-side evaluation against a raw Ollama baseline, where ABES passed 14/15 blocks and the baseline passed 6/15
a 200-prompt cognitive stress test reported as 3 consecutive runs at 200/200
Two easy verification points:
run PYTHONPATH=$PWD pytest tests/ -q from the repo root
inspect results/side_by_side_eval.json for the block-level comparison output
I do not consider internal tests and project-published evals to be sufficient external validation. The next stages are stronger benchmarking, improved contradiction handling and belief revision, stronger temporal and relational structure, longer-horizon testing, multi-agent shared memory work, and better observability of belief transitions.

Show HN: A simple, auto-layout family tree generator
I built this as a side project because I found existing family tree tools either too bloated or too manual—I spent more time dragging boxes and aligning lines than actually mapping my family history.
My goal was to make it instant: you just add the names, and the auto-layout engine handles the hierarchy and spacing automatically. It runs entirely in the browser and exports high-res PNG/JPGs.
Would love feedback on the layout logic (especially for complex families) and the overall UI flow. Happy to answer any questions!
