AI mention inbox
Business and FinanceBuild a lightweight brand-mention monitoring assistant: users enter a brand name, competitor names, and product keywords, and the system collects public mentions from communities and the web. It sorts them into task cards for potential customers, complaints, competitor comparisons, and media opportunities, then generates editable reply drafts. The core is not a large social-listening dashboard. It is an inbox that users open each day to see which mentions need immediate attention.
Baggage-fee booking checker
Travel and TransportationBuild a single-page tool where users enter a route, airline, fare class, whether they are checking bags, and their carry-on bags. The tool returns the baggage-fee items that may apply to that combination, along with links to official rules and a checklist that users can save. In the typical summer family-travel scenario, a parent compares flights on Google Flights, Kayak, or an airline website and views the low fare and baggage needs in one table. This differs from existing approaches by preserving the checking process and official-rule evidence instead of only displaying a flight price or a static fee chart.
Google Tasks client follow-up board
Business and FinanceBuild a lightweight planner centered on Google Tasks. After users connect their Google account, it automatically organizes scattered client follow-ups, quotes, and delivery tasks from their task lists into boards for today, this week, and overdue. Users can drag tasks to change dates, add notes in bulk, and generate a one-page weekly plan. It suits small agencies and service businesses that do not use full project management software.
OpenWrt configuration manager
TechnologyBuild a local-first web tool that connects to an OpenWrt router, reads its configuration automatically, and generates rollback-ready snapshots, migration checklists, and security check reports. A typical scenario is a part-time network administrator replacing a router, changing Wi-Fi, or enabling a guest network for a small office: they back up the current state, follow the checklist, and then export a delivery report for the customer. The tool focuses on configuration migration, backup, and handoff records, which remain largely manual.
Student loan gap calculator
Business and FinanceBuild a single-page calculator for families to enter school costs, aid already received, the amount the family can pay, student status, and enrollment timing. It estimates how much remains after federal loans are applied under the new borrowing rules. The results page provides a downloadable family budget sheet, a draft inquiry email for the school’s financial aid office, and official links to verify. It focuses on the enrollment funding gap rather than loan applications, private-loan offers, or every repayment plan.
Chinese consumer-rights email assistant
Law and GovernmentBuild a single-page application for everyday consumers: users upload order screenshots, customer service chats, and merchant policy pages, then choose a scenario such as "refund denied," "subscription cancellation," or "flight or hotel after-sales support." The app automatically organizes a timeline, an evidence checklist, and copyable email or live-chat scripts. The first version does not send messages on the user’s behalf or promise a successful outcome. It only removes the burden of organizing materials and finding the right wording.
Independent app trust check
TechnologyBuild a single-page tool where users enter an app website, store page, or download link. It automatically checks details that affect first-time trust: whether the domain and email match, whether a privacy page is missing, whether screenshots are outdated, whether social links are empty, and whether the download page looks like a phishing page. It outputs a prioritized fix list for prelaunch self-checks. Unlike general security or performance tools, it focuses on the credibility gaps that can stop someone from trusting an independent app on their first visit.
Build a one-page tool for U.S. Medicare beneficiaries and their family members. After users answer questions about their insurance type, treatment purpose, prior diagnoses, and doctor’s prescription, it generates an eligibility assessment, a prior authorization materials checklist, and question scripts for the doctor and pharmacy. The product only organizes information and cites official links. It does not replace medical advice.
Small-office printer rescue
TechnologyBuild a single-page troubleshooting app for nontechnical office owners. An employee opens the webpage and follows prompts to check the system print queue, default printer, network connection, paper, and error lights, then generates a repair report that can be forwarded. The owner or outsourced IT provider can immediately see whether the problem is the computer, network, driver, or printer itself, with fewer back-and-forth requests for screenshots. Unlike existing tools focused on print management or connectivity, it produces a lightweight diagnostic package for a single incident.
Student loan plan transition reminders
Business and FinanceBuild a single-page tool for US student loan borrowers. Users select their loan servicer and enter or upload the SAVE transition notice they received. The tool extracts key dates, required actions, and official links, then generates calendar reminders and a one-page checklist. A typical borrower receives a notice related to RAP and does not know whether to log in, when to act, or which materials to prepare. Unlike existing approaches, it turns the notice itself into actionable tasks and reminders.
Gemini migration checker
TechnologyBuild a code-scanning and migration-reporting tool that reads Gemini calls, SDK versions, request structures, and interaction data formats in a project. It flags locations that may be affected by deprecations and structural changes. The report provides before-and-after migration examples, helping teams spend less time searching release notes.
Pinterest product-selection dashboard
Business and FinanceBuild a product-selection and posting dashboard for creators that connects to Amazon Storefront product lists. It organizes products into ready-to-publish Pins by Pinterest-friendly themes, seasons, price ranges, and image assets. Users can generate titles, descriptions, asset checklists, and attribution tables. It is suited to small affiliate creators.
Store checklist generator
Business and FinanceBuild a small tool for stores, guesthouses, repair work, and event operations. Users enter a scenario such as a pre-opening check, room cleaning, or equipment handover. The system generates an editable checklist with an assignee field, a photo evidence field, and a PDF. The focus is not general-purpose checklists, but industry templates and print quality.
YouTube privacy checkup
TechnologyBuild a Chrome extension that scans public videos, unlisted videos, playlists, external links in descriptions, and collaborator permissions after a creator signs in to YouTube Studio. It flags entry points that could make private content discoverable. The first version will not handle downloads or cracking. It will provide only a risk checklist, remediation steps, and periodic reminders.
CPSC certificate completion assistant
Law and GovernmentBuild a compliance workspace for FBA and import sellers. Users import a product list, get category-based prompts for missing certificate fields, upload test reports and supplier documents, generate a submission checklist, and mark gaps for each product. The workspace brings together information scattered across spreadsheets, email, and supplier files. It focuses on organizing documents and flagging gaps rather than replacing existing submission, legal, or customs processes.
EU landed-cost calculator
Business and FinanceBuild a landed-cost and responsibility guidance tool for small cross-border sellers: they enter the product category, shipping origin, destination country, sale price, and shipping cost, then get a buyer-facing landed-price explanation, store announcement copy, and order-processing notes. The focus is not to replace customs systems. It is to help sellers quickly update product pages and customer-service messaging.
Build a desktop companion app and template library that lets users display their Steam online status, current game, wishlist, controller battery level, weather, and calendar on an e-ink screen. The first version would not sell hardware. It would provide a setup wizard for existing screens, theme previews, a sync program, and community submissions.
