Turn hand-editing YAML for chained proxies into a fill-in form
Problem
Users who chain proxies to a static residential IP for Claude/ChatGPT keep hitting Timeout because the dialer-proxy name doesn't match the node name — one wrong character kills the whole chain, and hand-editing YAML is painful for non-experts.
Solution
Users enter only the relay node and residential IP credentials; the tool validates name consistency and generates Clash Verge extension scripts, Shadowrocket confs, and OpenClash overrides, with built-in connectivity self-checks and error hints.
Tame the explosion of AI coding sessions, projects, and context
Problem
Heavy Claude Code / Codex users end up with dozens of sessions and project folders, lose track of which chat holds what, and have to re-explain context every time they open an agent — some say they stop opening the agent at all.
Solution
Locally index agent conversation logs and project folders, auto-cluster by project, and generate one-line summaries with tags; search across all sessions to find where a topic was discussed; export reusable context cards for the next session.
Filters false positives and nitpicks from AI code reviews so engineers only see what matters
Problem
After heavy use of Claude/Codex for coding, PR volume explodes and humans cannot review line by line. Teams try CodeRabbit and Copilot for AI review but get too many false positives, so engineers spend more time triaging trivial comments and PRs drag on for a long time.
Solution
A noise-reduction layer for AI code review: connect to GitHub/GitLab PRs, deduplicate and risk-rank comments from existing AI review tools by confidence, collapse obvious false positives and formatting nitpicks, and surface only high-confidence real defects. Supports custom rules and team preference learning.
Rule-based forwarding of Mac app notifications to your phone when mobile push fails
Problem
Some messaging or work apps stop delivering push notifications to iPhone, yet notifications arrive fine on Mac when it is online, causing missed messages. Existing solutions either lack per-app and keyword filtering or require complex setup, and there is no simple reliable forwarding rule tool.
Solution
A Mac menu bar utility that reads notifications from Notification Center, filters them by app and keyword rules, and forwards to iPhone via existing push services like Bark. It supports multiple rules, quiet hours, tap-to-open source app, and minimal configuration.
Remembers speed, A-B repeat, and progress for online courses and tech tutorials
Problem
Watching online courses and tech tutorials in general-purpose players is awkward: users must reset playback speed for every video, repeatedly drag the scrubber to replay unclear parts, struggle to access courses on NAS, and interrupt playback when switching windows for notes. Learners need a player optimized for studying.
Solution
A cross-device learning player with a global speed setting set once, A-B loop for confusing segments, chapter and timeline thumbnail navigation, per-video progress memory, dual subtitles for language learning, direct WebDAV/SMB playback of NAS courses, picture-in-picture for note-taking, and iCloud progress sync.
Sort iCloud videos by actual file size to find the biggest space hogs in seconds
Problem
iCloud storage is full again, but the Photos app cannot sort by file size, so users don't know which video takes the most space. Manually digging through thousands of videos is slow and error-prone, while third-party cleaners often inject ads or upload data, raising privacy concerns.
Solution
A local-first desktop utility that scans the photo library and ranks videos and photos from largest to smallest by actual bytes, flags byte-identical duplicates, shows space usage by year/month, and lets users one-click select redundant copies for deletion via the system Photos app (recoverable for 30 days). No account, no uploads, no third-party dependencies, extremely lightweight.
One-click diagnosis for intermittently failing payment callbacks so indie devs stop losing orders
Problem
Online payments fail intermittently—about 1 in 10 callbacks throws signature mismatch—while local replay and production packet replay both pass. After three days it turns out a gateway strips a URL path prefix and the verifier re-joins timestamp after parsing, so the signed string differs. Indie devs and small teams have no systematic tool to compare raw payloads, middleware rewrites, and signed strings.
Solution
A local debug workbench: import the gateway's raw request capture and your verification code config, then automatically compare path, query params, timestamp units, empty-value handling, and concatenation order. It outputs a diff report and highlights middleware-modified fields. Ships with signature templates for common gateways (WeChat Pay, Alipay, Stripe, PayPal) and one-click regression tests.
Know whether a redesign will hurt organic traffic instead of launching on anxiety
Problem
Indie founders fear redesigns most when things finally work: one had organic traffic trending up and worried a big visual update would disrupt it, with no data to decide. Builders also stall on launch-now-versus-polish-later, lacking a cheap way to let data decide.
Solution
A minimal landing-page and SEO A/B tool: connect a site, snapshot the current version, split traffic between old and new, track keyword rankings, click-through, and conversion, then recommend ship-or-wait with a rollback record.
Pull Excel rotas, WhatsApp leave requests, and paper contracts into one lightweight board for small cafes and bakeries
Problem
Small food-business owners have no HR or accounting team, so rotas live in Excel, leave requests in WhatsApp, and contracts scattered across email. Hiring surges and off-season gaps make staffing and payslips error-prone, and owners say that admin crunch is their biggest time sink.
Solution
A minimal scheduling tool for single-location food businesses: drag a weekly rota, let staff confirm shifts or request swaps on mobile, auto-tally hours into a payslip export, and surface holiday and contract-expiry reminders. Owners see who is on and who is out on one page.
Find out which 'AI crawlers' are really faking GPTBot to scrape your .env files
Problem
Sites let AI crawlers in to appear in ChatGPT and Perplexity answers, then attackers spoof GPTBot, ClaudeBot, GrokBot, and Googlebot UAs. One server hit a site 66 times in 12 seconds, every request claiming a different bot and asking for a different .env file. The fix is IP verification, not UA trust, but most small teams lack tooling and time.
Solution
A lightweight hosted or self-hosted audit service parses access logs, validates every self-declared AI crawler against official IP ranges, flags spoofed traffic and sensitive-path probing, and generates actionable WAF/nginx/Cloudflare rules plus a daily security brief.
Fix Mermaid subgraph direction and add local snapshots so documentation diagrams stay sane
Problem
Heavy Mermaid users hit a long-standing limit: if any node inside a subgraph connects outside, the subgraph ignores the overall direction and the layout becomes unreadable. The official live editor also keeps no history, so a refresh loses work. One developer had to add new syntax and local-storage snapshots themselves.
Solution
An enhanced Mermaid renderer and local editor that supports stack layout and corrected subgraph direction, improves cross-layer edge routing, and auto-saves every edit to browser local storage as browsable snapshots; export to standard Mermaid or SVG for docs.
Make the screen visibly glitch when your AI agents need you, instead of a notification you ignore
Problem
Developers running multiple coding or automation agents constantly miss the moment an agent asks for confirmation, errors out, or waits for input, because it lands in a muted notification. One builder missed attention requests so often they made a tool that glitches the whole desktop. Account-limit handoffs mid-session have the same visibility problem.
Solution
A tiny desktop daemon polls local agent logs or hooks; when it sees a pending confirmation, failure, or quota warning it fires a full-screen visual effect, menu-bar/taskbar highlight, and custom sound, with one-click jump back to the session. Users can tune intensity per event type.
Offline audit of what your AI tools keep on your machine
Problem
Developers use ChatGPT, Claude, Copilot, and more side by side, leaving chats, code snippets, and uploaded files scattered across vendors with no clear picture of who stores what or how to delete it. Someone built an offline AI Data Footprint Tracker, confirming the privacy anxiety, but users need concrete guidance on which data lives where and how to remove it.
Solution
Ship an offline desktop tool that scans local caches, exports, and configs of common AI tools. Summarize data categories (chats, code, attachments) per tool, provide deletion steps and export paths for each category, and generate a shareable audit report, all processed locally with no uploads.
A local-first drawing library for heavy Excalidraw users
Problem
People who draw with Excalidraw end up with .excalidraw files scattered across folders, making it hard to find diagrams, reuse shapes, or compare versions. Someone built xcalidraw, a local-first desktop app for managing Excalidraw drawings, showing that native file organization is missing and users do not want to upload their diagrams to a third-party cloud.
Solution
Scan local folders and index every Excalidraw file with thumbnail browsing, full-text search, tags, and favorites. Let users extract frequently used shapes into a personal asset library. Store everything locally with optional Git or cloud-drive sync and zero uploads.
Approve and reply to agent sessions from your phone safely
Problem
When coding agents run inside cmux or tmux, developers who step away from the desk get blocked on permission prompts or questions. Someone built Muxer for Android with a relay to the local socket, proving that handling agent sessions away from the desktop is a real, frequent pain, but existing solutions cover only one tool and one platform.
Solution
Offer a lightweight relay (self-hosted or managed) that turns agent permission requests, questions, and plans from terminal sessions into phone notifications. Users can approve, reply, or stop sessions from their phone. Support common session sources like cmux, tmux, Claude Code, and Codex.
AI-customizable budgeting for freelancers earning in multiple currencies
Problem
Freelancers and small business owners often juggle multiple revenue streams, volatile monthly income, and constant relocation across countries, so currencies and spending contexts shift constantly. Someone built Open Accountant precisely because existing tools fail to handle multi-currency, fluctuating income, and mixed business/personal spending in one place.
Solution
Support multi-currency accounts with live FX conversion and scenario-based cash-flow forecasts (conservative vs optimistic). Tag transactions by project or client to separate business and personal spend. Let AI learn the user's habits and propose custom categorization rules, then surface actionable advice like whether a low-rate gig is viable this month.
Track CI spend and build speed driven by coding agents
Problem
Teams increasingly let Claude Code and Codex open PRs automatically, which multiplies CI runs and costs. A recent Ask HN thread asked how fast people's CI is now, noting that CI costs are generally rising in the agent era, and there is no tool that attributes per-build spend to agent-triggered work or shows where to optimize.
Solution
Connect read-only to GitHub Actions or GitLab CI and break down build minutes and cost by repo, branch, and trigger source (human vs agent). Flag redundant builds triggered repeatedly by agents and suggest caching, parallelism, or skip rules. Show daily cost and speed trends in one dashboard.
Warn valet attendants when a table is about to leave, using the POS closing signal
Problem
Valet attendants at restaurants get zero warning before a table actually leaves, so slow nights turn into sudden rushes: attendants scramble and guests wait impatiently for their cars. Both valet and restaurant staff repeatedly cite the same complaint: nothing notifies valet when a table is wrapping up.
Solution
A lightweight alert tool: when a table is about to close (via POS integration or a simple staff tap of 'closing soon'), the valet attendant's phone gets a push with the table and ticket or plate suffix, so the car can be pulled to the curb ahead of time.
Fill your product info once, reuse it across every directory, partner and launch form
Problem
Indie developers re-type the same product details into form after form: product name, website, short and long descriptions, founder bio, LinkedIn, pricing, company size, category. Directories, partner forms, waitlists and launch sites each demand their own version, and Chrome autofill is useless for these custom fields.
Solution
A structured product profile library: enter your product's details once, then fill any launch, directory or partner form in one click via a browser extension or bookmarklet. Supports multiple profiles, field-alias learning and a preview before filling.
A dedicated page per sponsored deal or referral, so old posts keep working when codes and links change
Problem
After a creator posts a sponsored deal or referral, the promo code expires or the target link changes, but the old post and group chat messages can't be updated, so fans hit dead links and conversions leak away. Stuffing every link into a bio page doesn't carry the pitch and code of a single deal either.
Solution
Create a dedicated landing page per deal or referral that holds the description, promo code and outbound link together. Later, edit the code or swap the link in the dashboard and the already-shared short URL points to the new content automatically. Show click and code-copy stats so creators know which deal is worth re-promoting.
