I built AI agents that do the grunt work solo founders hate

Sat, 02/28/2026 - 10:03pm

Hey HN,

I'm a solo founder. Every morning I was spending 2 hours doing the same things: checking competitors, reading AI news, monitoring my Stripe dashboard, looking at Google Trends for content ideas.

So I built Seleci to automate all of it.

What it does: You pick a template (Market Pulse, Revenue Radar, Trend Scout), click deploy, schedule it, and every morning you get a clean markdown report — no code, no Zapier flows, no prompt engineering.

How it works under the hood:

FastAPI backend with an agentic loop (tool-calling LLM with web search, Stripe API, Google Trends) Per-tool rate limiting to prevent runaway agent loops (web_search capped at 3 calls/run) React/Vite frontend, Supabase auth, deployed on Koyeb + Vercel The agent actually executes tools and returns structured results — not a chatbot wrapper What it's NOT:

Not another ChatGPT skin Not a no-code workflow builder (no nodes, no drag-and-drop) Not trying to replace developers — it's for the founder who doesn't have one Live demo: https://seleci.com

I'm applying to YC with this. Would love brutal feedback from HN via Discord — what's missing, what's broken, what would make you actually use this?

Show HN: A visual sitemap editor that forces you to design structure before UI

Sat, 02/28/2026 - 9:49pm

Most web tools start with UI. Templates. Components. AI layouts. But structure — the sitemap, the navigation logic — usually comes later. So I built a tool: https://no-edit.lovable.app A browser-based visual sitemap + navigation editor where you design the hierarchy first, before touching visuals. Core idea: Pages are nodes Navigation is explicit Hierarchy is visible at all times You can’t “accidentally” create structural chaos Instead of designing a homepage first, you design the map. Then the UI sits on top of that structure. What I’ve noticed: Users spend time reorganizing structure before styling Navigation clarity reduces later edits Thinking in hierarchy changes how features are added I’m curious: For those who’ve built CMSs, IDEs, or large web apps — Should structure be a first-class citizen in design tools? Or is it something users only care about at scale? Would love technical feedback on the approach. Link in comments.

Show HN: MCP server that strips injection vectors from LLM input

Sat, 02/28/2026 - 9:39pm

also cuts tokens 93%

Claude Code's WebFetch converts HTML to markdown and runs it through a secondary model before it hits your context — but that pipeline wasn't designed as a security boundary. Turndown strips structural junk (scripts, CSS, nav chrome), but zero-width characters, fake LLM delimiters, base64-encoded payloads, and markdown exfiltration URLs all survive the conversion. And using a small LLM to filter adversarial content is the fox guarding the henhouse.

The problem gets worse outside Claude Code. API-level web_fetch, other coding tools, curl output, cloned repos — raw content flows into LLM context with no sanitization at all.

mcp-safe-fetch is an MCP server with three tools (safe_fetch, safe_read, safe_exec) that sanitize content deterministically before the LLM sees it. Regex + cheerio + turndown, no AI in the loop. Across 4 test sites: 93% average token reduction, zero false positives, all visible content preserved.

Show HN: ChoresMates – Splitwise, but for Household Chores

Sat, 02/28/2026 - 9:32pm

Hey HN, I built ChoresMates to solve a problem every couple and roommate knows: the "I do more around the house" argument.

The idea is simple — every chore gets a point value based on effort (cooking dinner = 8 pts, loading the dishwasher = 2 pts). When you complete a chore, you log it and earn points. A real-time leaderboard shows who's actually pulling their weight. The numbers replace the argument.

A few things that make it work in practice:

Effort-weighted points — Not all chores are equal. Scrubbing the bathroom is worth more than wiping a counter. This prevents gaming the system with a bunch of tiny tasks. Overdue penalties — Procrastinating on an assigned chore costs you points per day. Creates just enough pressure to get things done. Photo proof — Solves the "I did it but you didn't notice" problem. Rotation scheduling — Automatically rotates who's responsible for recurring chores, so there's no negotiation. Comes with 100+ chore templates covering everything from couples to families with kids to college dorms, with sensible default point values and schedules.

Tech stack: Swift/SwiftUI on iOS, Kotlin on Android, Rails 7 API backend on AWS ECS, PostgreSQL. Auth via Sign in with Apple, Google, or email.

Free tier covers most households (1 group, 10 members, 25 chores). Pro is $0.99/mo or $19.99 lifetime.

Would love feedback from the HN community — especially on the point-value system and whether the gamification angle resonates or feels gimmicky.
