A Mac File Shrinker That Handles Audio, Video, And Images

Dinky is a native macOS app that makes files smaller, reaching 438 GitHub stars from Mac users who want a simple drag-and-drop compressor instead of fiddling with HandBrake or command-line tools, and its issues map out the path from one-trick utility to daily tool: users want audio formats like MP3 and M4A added alongside the existing image and video support, configurable FPS for shrinking screen recordings, a floating dropzone for quick compression like Clop, JPEG presets for maximum compatibility, and quality-of-life touches like hiding the dock icon. People want one fast, native app that shrinks whatever file they throw at it without thinking about codecs. The wedge is a unified Mac compressor that covers images, video, and audio with smart presets.

Problem Statement

A Mac user wants to quickly shrink a file to fit an upload limit or save space, but the app only handles images and video, has no audio support for MP3 or M4A, offers no FPS control to shrink screen recordings, and lacks a quick floating dropzone, so for anything outside its narrow scope they fall back to HandBrake or the command line. The simple drag-and-drop compression is exactly the experience they want, but a compressor that only covers some file types forces them to keep multiple tools around.

The Idea

A native macOS compression app that shrinks images, video, and audio with smart presets and a quick floating dropzone so users never reach for HandBrake or the command line.

Why Now

Larger media files, upload limits, and the popularity of Clop showed in 2026 that Mac users want frictionless, native compression, and Dinky's traction confirms it, but its missing audio support, lack of FPS control, and absent quick dropzone show that breadth of formats and workflow speed, not raw compression, are what stand between a single-purpose utility and a tool people use every day.

AI Meeting Companion That Completes Follow-Up Tasks Before the Next Meeting

Meeting notes tools transcribe and summarize meetings but the action items they extract sit unfinished in a list. An AI meeting companion that not only captures action items but autonomously completes appropriate follow-ups (drafts emails, creates tickets, schedules meetings, updates CRM) before the next meeting closes the gap between meeting decisions and execution.

Meeting-to-Sprint Automation Bridge for Agile Development Teams

Memolect transcribes meetings and suggests Jira updates, but the full opportunity is a meeting-to-sprint bridge: automatically converting sprint planning, standup, and retrospective meetings into structured sprint artifacts (user stories, acceptance criteria, blockers, retro action items) that flow directly into the project management tool without manual transcription.

Async Meeting Replacement Tool for Distributed Teams Across 5+ Time Zones

notigo.ai provides real-time meeting summaries. But for teams spanning 5+ time zones, real-time meetings are the problem, not the solution. A structured async meeting replacement, where participants record responses to an agenda asynchronously, AI synthesizes the inputs, identifies disagreements, and produces a decision document, would eliminate the 'who can make the 7am call' problem entirely.

Personal Knowledge Grounding Layer for AI Assistants

Knowledge workers using AI assistants get generic outputs because the AI lacks access to their accumulated personal knowledge, bookmarks, highlights, notes, and saved research. Liminary connects personal knowledge bases to AI assistants, grounding responses in the user's own curated information.

Searchable Knowledge Vault for Podcast and YouTube Learners

DistillNote demonstrated demand for converting YouTube videos and podcasts into searchable, structured notes with AI-powered summaries and cross-vault semantic search. The opportunity is a personal knowledge management tool specifically for audio-visual learners who consume 10+ hours of podcasts and videos weekly but cannot search or reference what they learned.

AI Voice Memo to Structured Task Converter for Solo Founders

Solo founders on Indie Hackers frequently describe capturing ideas and tasks via voice memos during commutes or walks, then losing them in a sea of audio files. A tool that transcribes voice memos, extracts actionable tasks, categorizes them by project, and pushes them to existing task managers would close the capture-to-action loop.
