Circle and label a screenshot, get structured JSON your coding agent can execute
Problem
When revising AI-generated UIs, users often type long descriptions like "move the button top-right a bit left", "make this card bigger", or "the color here is wrong". The intent is clear but text is imprecise about position and scope. Someone already built a small tool that turns annotations into JSON for AI, confirming the pain is real and repeatable.
Solution
Select, drag and annotate components directly on a screenshot or live page, express intent like "shift left 8px" or "increase font size", and get structured JSON or natural-language instructions including element position, relative relationships and change type, ready to paste into a coding agent or send to a designer.
For hourly and salaried workers who want to know when they can coast or quit
Problem
A user built a life-stage financial planning tool in a few hours to figure out how long they must work to coast or retire, and the post drew 40+ comments and 40+ upvotes, showing many people are stuck on this question. Existing calculators are mostly US 401k-style retirement tools and don't fit freelancers, hourly contractors, or cross-border earners.
Solution
Enter current hourly/salary rate, savings rate, expected spending and portfolio return, and get two dates: when you can coast and when you can fully retire. Also shows how changing jobs or taking a pay cut shifts those dates. Save scenarios as snapshots to compare life stages.
Replace Chinese text on web pages with natural English for passive learning
Problem
A developer noticed that embedding English into Chinese web pages helps users passively absorb English. But the Safari version of a similar extension didn't exist, so he built his own. This suggests an unmet need on a specific browser with a user willing to code it themselves.
Solution
A Safari extension that replaces Chinese phrases on web pages with natural English translations, plus a word/sentence collection and review feature. It supports site whitelisting, difficulty tiers, and hover-to-see-original, letting users encounter English during natural reading.
Pay-per-use access to top AI models for infrequent users
Problem
A user says his non-coding friends need top models only occasionally — a few times a month at most. Paying for a Plus subscription isn't worth it, so they're stuck with weaker models. Meanwhile, second-hand account trading for ChatGPT has its own code words, showing real demand with no legitimate low-frequency option.
Solution
A compliant API proxy layer that charges per use or per token, letting users access top models without a monthly subscription. It provides a simple web chat UI, prepaid balance, usage alerts, and targets individuals with occasional needs.
Automate browser interactions and generate visual test reports
Problem
A developer says his company requires front-end interaction test screenshots and API test reports before handing issues to QA. He uses Cursor + Chrome MCP to control the browser, but even simple scenarios take half an hour — most of it wasted on back-and-forth MCP-agent interactions.
Solution
A browser automation tool focused on generating visual test reports. Record human actions, then replay and screenshot automatically. It produces a report with step descriptions, timestamps, and assertion results, ready to paste into issue comments. Optimized to reduce repeated agent round-trips and support parameterized inputs.
Catch design flaws in AI-generated code for non-programmers
Problem
A developer with coding experience watched a non-programmer friend try to vibe-code a product. The friend struggled with Python syntax and Git, then shifted to workflow design. The root issue: AI writes code fast but misses general abstractions, and non-programmers can't spot code that will cause problems later. Another poster jokes about building a vibe-coded app for zero users.
Solution
A lightweight review assistant that scans AI-generated code for common anti-patterns (hardcoding, duplicated logic, swallowed exceptions) and explains in plain language why each will hurt later, with concrete refactor suggestions. It also logs each AI change for easy rollback and comparison.
Turn chart-heavy professional PDFs into queryable structured knowledge
Problem
A developer trying to structure the Chinese medical textbook Internal Medicine found that after splitting by table of contents, he got stuck on parsing images, tables, and flowcharts. AI-generated parsing scripts kept failing. In medical texts these diagrams carry diagnostic logic that is lost if dropped.
Solution
Upload a PDF, automatically split by chapter, extract tables/flowcharts/diagrams as structured fields. Provide disease-centric knowledge card templates and export JSON/CSV for downstream training or retrieval. Mark unparseable diagrams for human review rather than silently dropping them.
A CC0 collection of retro 3D tricks ready to paste into web pages
Problem
Web developers wanting retro 3D effects (like old-school rendering or pseudo-3D animations) must search and piece together code from scratch, lacking a centralized, freely usable snippet library.
Solution
A CC0-licensed online museum of retro 3D snippets that can be pasted into web pages, each with a demo and explanation. Developers can copy and integrate directly without licensing worries.
Generate printable recipe cards for food bloggers and home cooks
Problem

Solution
A lightweight web app that takes ingredients and steps and generates beautifully designed recipe cards, exportable as PDF or images for printing or social media. It includes multiple templates and font choices.
Enable multi-device switching on old Logitech keyboards and mice without new hardware
Problem
Users with older Logitech devices like the first-gen MX Master must flip the mouse to press a bottom button when switching between two computers, and the keyboard switches separately. Logitech's Options+ multi-device switching only supports newer devices.
Solution
A small desktop utility that simulates shortcuts or calls Logitech driver APIs to let legacy devices switch mouse and keyboard to another computer with one key press. It supports custom hotkeys and switch presets across platforms.
Daily-updated LLM API prices, each with official source links
Problem
Developers struggle to compare real-time LLM API prices because they change often and sources are scattered across vendor docs. Budgeting or model selection requires manual verification, risking decisions based on outdated prices.
Solution
A website that automatically checks major LLM API prices daily and records source links. It offers a comparison table, historical price changes, and a cost estimator by token usage, with every price linked to official docs.
Traceable expiry and approval records for CI/CD security exceptions
Problem
Teams frequently use break-glass overrides in CI/CD or Kubernetes to bypass failing security gates, but there's no reliable record to prove the exception was valid six months later. Approvals are scattered across Slack, email, and tickets, making audits painful.
Solution
A lightweight SaaS/CLI tool that automatically logs who bypassed which gate, when, and why, creating a searchable audit trail. It sets expiry reminders and periodic review tasks so every exception has an owner and deadline.
Help overseas devs know which AI coding subscriptions actually work and don't get banned
Problem
Working abroad but company API is internal-only, so side projects need self-funded subscriptions. Devs want to know if Codex Plus is best value, whether Gemini can code, and if Claude bans easily, but info is scattered across forums with no reliable live comparison.
Solution
A community-driven subscription availability board aggregating region availability, ban reports, pricing, and feature comparison for major AI coding subscriptions. Users filter by region and use case (coding/translation/mobile photo), and subscribe to change alerts.
Turn a screen recording into a clean product demo in 20 minutes
Problem
Recording a product demo seems like a 20-minute task, but the whole afternoon disappears checking framing, cutting unnoticed pauses, and re-recording because the mic was muted. SaaS founders need demos for clients or launch pages, but editing is slow and fiddly.
Solution
A lightweight browser-based tool that uploads screen recordings, auto-detects and cuts silent pauses, offers simple trim, auto-subtitles, and export presets. No pro editing skills needed, focused on fast product demo turnaround.
Bring scattered supplier order details from WeChat, email, and chat into one board
Problem
When sourcing overseas, pricing and quantities are agreed on WeChat, the PI arrives by email, spec changes happen in chat threads, and deposit terms are in a different email from two weeks ago. Finding what was decided about packaging means digging through three apps.
Solution
A lightweight board that aggregates manually pasted key info from WeChat, email, and chat by supplier/order. Users forward or paste messages into the relevant order; the tool organizes price, quantity, specs, and terms into a timeline with search and export.
Turn local meeting transcripts into agent-ready context packs
Problem
Developers spend hours in meetings discussing requirements, then have to manually re-explain everything to coding agents. There is no direct bridge between local meeting records and agent sessions, causing repeated context loss.
Solution
A CLI tool that watches local meeting recordings/transcripts, extracts decisions, action items, and key context, and generates structured summaries injected into agent sessions. Supports folder watching and a simple command for agents to pull the latest context.
Help Windows native devs pinpoint crash root causes without wrestling WinDbg
Problem
Windows crash debugging is split between Visual Studio (friendly but limited) and WinDbg (powerful but archaic). Developers waste hours switching tools and interpreting raw stacks just to understand why a program crashed.
Solution
A local-first desktop tool that auto-parses minidumps/crash dumps, shows call stacks, thread states, exception types, and suspicious modules in a modern UI; one-click shareable diagnostic report; auto-flags common crash patterns like null pointers, heap corruption, DLL load failures.
A Chrome extension that uses AI to filter low-quality and AI-generated content on LinkedIn
Problem
The LinkedIn feed is flooded with AI-generated slop, empty platitudes, and low-effort promotion, making it hard to see valuable updates and causing information anxiety.
Solution
A browser extension that identifies and collapses low-quality, repetitive, or AI-generated content using local or lightweight AI, giving users control over their feed with adjustable filter strength.
Capture, inspect, and forward webhooks locally without relying on third-party cloud services
Problem
Debugging webhooks requires a public endpoint to receive and inspect requests, but existing tools either depend on third-party clouds (privacy risk) or are too complex, lacking a smooth local-to-prod workflow.
Solution
A locally runnable webhook relay that provides a temporary public URL to capture requests, view/edit/replay them, and forward to local or private infra (optional mTLS) — no external SaaS required.
Monitor and de-escalate potentially harmful long AI chats to protect vulnerable users
Problem
Long conversations with LLMs can reinforce delusions or paranoia, especially when the model validates harmful ideas. There is a lack of real-time user-facing safety guardrails.
Solution
A local plugin that analyzes user-LLM interactions and gently alerts or suggests a break when signs of delusion, paranoia, or dangerous fixation appear, with mental health resources.
