Paid, polished window snapper for Mac power users
Build a polished, paid window-snapping and tiling app for macOS aimed at power users and ex-Windows switchers who miss FancyZones/Divvy-style layouts. Package it as a one-time purchase or small subscription on the Mac App Store and gumroad-style sites, with custom layouts, keyboard shortcuts, and multi-monitor profiles that the free open-source tool leaves unpolished.

White-label SaaS on top of open-source Office clones
Fork and customize Puter's open-source web OS components (browser-based Photoshop, Office, CAD, and spreadsheet clones) into a niche, white-labeled SaaS for a specific underserved audience, such as schools, SMBs, or teams in regions where Adobe and Microsoft licensing costs are prohibitive. Monetize through hosting, support, and vertical-specific customization rather than building the core editors from scratch.

Airtable alternative and migration tools after layoffs
Build lightweight, cheaper alternatives to Airtable-style no-code database/workflow tools aimed at the small teams and solo users Airtable is likely deprioritizing post-layoffs, such as a simple spreadsheet-database hybrid with forms, views and automations. Also target the niche of an Airtable data exporter/migration tool for users worried about platform stability who want to move their bases to Postgres, Notion or a self-hosted alternative.

On-device semantic file search for Mac power users
Package a polished macOS menu-bar app that lets users semantically search everything on their Mac (photos, PDFs, recordings, videos, code) using on-device embeddings, with no cloud upload. Target privacy-conscious professionals, researchers and developers drowning in local files who don't trust cloud indexing tools like Rewind or Spotlight's weak search. Sell as a one-time license or low-cost subscription through the Mac App Store or a landing page with Product Hunt launch.

Privacy-first local AI summarizer for browsers
Build and sell a privacy-first browser extension that summarizes articles, YouTube and Bilibili videos, Wikipedia pages, and Hacker News or Reddit threads using fully local inference (WebGPU, Transformers.js, or a local Ollama instance). Mozilla's own cloud-based Orbit was killed after a privacy backlash, leaving a validated use case with no official successor, so a solo builder can target privacy-conscious Firefox and Chrome users with a no-data-leaves-device alternative and monetize through a pro tier with extra model options, team sync, or bundled local-AI browser utilities.

Open-source NotebookLM alternative for churned Google users
Build or position a lean open-source-based alternative to NotebookLM aimed at the churn of users frustrated by Google deprecating or hobbling beloved products. Target source-grounded research/Q&A over large document sets (up to 200 sources), paired with exportable study/report assets (mind maps, slide decks, short videos) for students, researchers, and content creators who want NotebookLM-like features without depending on Google's roadmap.

Plain-text cancellation emails beat survey forms
Build a lightweight churn-feedback tool for SaaS founders that replaces clunky Typeform exit surveys with a single plain-text email asking cancelers one open question, auto-sent via Stripe or app webhook, with replies aggregated and lightly tagged by theme in a simple inbox-style dashboard. Target solo SaaS builders and small teams on Zapier-style stacks who want real cancellation feedback without building the plumbing themselves.

Distraction-stripping browser extensions for feed-heavy sites
Build and sell a focused Chrome extension that strips distraction elements (feed, Shorts, autoplay, end screens, recommendations) from YouTube and similar attention-hijacking platforms, aimed at people trying to use these sites with intent instead of getting pulled into endless scrolling. Monetize via a Pro tier with sync across devices, scheduling, and parental controls, similar to the Quiet extension described, and extend the same pattern to other feed-heavy sites like Instagram, X, or Reddit.

Honor-system pushup app blocker for phones
Build a lightweight honor-system screen time blocker that gates distracting apps behind a quick task (pushups, a typed pledge, a breathing exercise) without requiring camera-based motion tracking. Target it at people who already use pushup-to-unlock apps but find camera tracking embarrassing or unreliable in public, selling via a simple one-time purchase or low-cost subscription on iOS and Android.

Browser-based room display billed per room monthly
A browser-based conference room display that pulls from Google Calendar and runs on any tablet or browser, no app install or proprietary hardware needed. Sell it as a subscription (around 10 dollars per room per month) to offices and coworking spaces that are tired of paying for dedicated room-booking hardware like Robin or Evie or dealing with buggy proprietary tablets.
