Clicky is a Mac application that surfaces an AI assistant inline — directly adjacent to your cursor — without requiring you to switch windows or paste context manually. The app maintains persistent screen awareness, reading what's in front of you and using that context to answer questions, guide tasks, and make suggestions relevant to what you're doing in any application. Unlike clipboard-based AI tools that require explicit copy-paste workflows, Clicky works through ambient screen reading: you invoke it with a hotkey, it understands the current screen context automatically, and responds inline. The approach is closer to GitHub Copilot's ghost-text model than a chat sidebar — the assistant lives where your attention already is. The indie approach prioritizes a single, focused Mac use case rather than trying to be a cross-platform agent platform. Early Product Hunt reception highlighted the overlay UI and the speed of context capture as standout experiences. For knowledge workers who context-switch constantly between reference material, documentation, and writing tools, the cursor-adjacent model reduces the friction of asking a question by eliminating the need to describe what you're looking at.

Gemma Gem is an open-source Chrome extension that runs Google's Gemma 4 language model entirely in your browser using WebGPU — no API keys, no server, no data leaving your device. Install the extension, wait for the one-time model download (500MB for the efficient 2B variant, 1.5GB for the larger 4B), and you have a fully private AI assistant that can read web pages, fill forms, take screenshots, and execute JavaScript. The extension uses Hugging Face Transformers.js with ONNX-quantized versions of Gemma 4's E2B and E4B variants, making the model small enough to run in a browser tab without throttling GPU memory. Gemma 4's strong efficiency profile — particularly its per-layer attention architecture — makes it a natural fit for WebGPU's memory constraints compared to older models at similar parameter counts. What makes Gemma Gem interesting beyond the cool factor: it's a glimpse at what fully private, zero-latency browser-native AI looks like. There's no round-trip to a server, no API billing, no rate limits. On a mid-range MacBook M3 or gaming GPU, inference is fast enough to be genuinely useful. The trade-off is capability — Gemma 4 E2B is a 2B parameter model, not Claude or GPT-5, but for summarization, form-filling, and basic Q&A it holds its own.
Reviewer scorecard
“The screen-aware context capture is the killer feature — I'm tired of pasting error messages into chat windows. If Clicky accurately reads terminal output and stack traces without me doing anything, that alone justifies the install. The hotkey-invoke pattern feels like the right UX for async assistance.”
“WebGPU inference in a browser extension is a technical achievement worth shipping just to see what's possible. The ONNX quantization pipeline here is clean and reusable. I'd fork this immediately for any project needing fully offline browser AI.”
“Persistent screen reading is a significant privacy surface. What data is captured, where it goes, and how it's retained are crucial questions that indie tools often underspecify. This space is also crowded — Cursor, Copilot, and a dozen similar tools already compete for this workflow. What's Clicky's durable advantage?”
“A 2B parameter model running in a browser tab via ONNX quantization is impressive engineering, but the actual capability is limited. For anything that requires reasoning, current knowledge, or multi-step tasks, you'll hit a wall fast. Fun demo, not a daily driver.”
“Cursor-adjacent AI is the right mental model for ambient assistance. We've been training users to alt-tab to a chat window for 3 years; tools like Clicky train the reflex that AI is contextually available wherever attention lands. This interaction paradigm will win.”
“On-device browser AI is the privacy endgame. When models are good enough to run locally in a browser tab, the cloud AI industry faces a genuine disruption threat. Gemma Gem is two years early to the party, but the party is coming.”
“As someone who constantly switches between design specs, documentation, and writing tools, cursor-adjacent AI is genuinely useful. No more describing a UI element in a chat window — Clicky can just see it. The overlay aesthetic is clean and the indie origin means it'll iterate fast on creator feedback.”
“The idea of an AI that reads web pages with me and answers questions without any privacy concerns is huge for creative research. I'm tired of pasting article excerpts into ChatGPT. This should be the default browser experience.”
