Memoket Gem is an AI-powered wearable recording device about the size of a domino (1.57 x 0.98 x 0.40 inches, 0.4 oz) that clips to your wrist alongside an Apple Watch or snaps into a pendant or clip. A single button press captures meetings, conversations, and spontaneous ideas, which the companion app transforms into structured summaries, action items, and searchable notes — automatically. Dual high-quality microphones pick up voices from up to 16.4 feet with built-in noise cancellation. What sets Memoket apart from competitors like Plaud and Rewind AI is its cross-conversation context linking: the app connects information across past and present meetings, helping you recall context without manual tagging. Battery life hits 20 hours of continuous recording on a single charge. Memoket is firmly privacy-first: recordings are never used to train public AI models and all data belongs to the user. The Product Hunt launch today garnered 175 upvotes, placing it at the top of today's leaderboard among a competitive field of AI productivity tools.

Comet is a standalone Chromium-based browser built by Perplexity that ships with a persistent AI sidebar agent. The agent can fill forms, summarize pages, conduct research, and execute multi-step web tasks without switching context. Early access is rolling out via waitlist to existing Perplexity users.
Reviewer scorecard
“The API hooks for pulling structured meeting data programmatically make Memoket genuinely useful for developers — you can pipe summaries into Notion, Linear, or your own tools with minimal friction. The hardware form factor is also more discreet than the Plaud NotePin.”
“Another wearable promising to remember your life for you. At $99+ plus a subscription for cloud sync, you're deep into Otter.ai / Plaud territory where the value proposition gets murky fast. The bigger issue: people near you don't always consent to being recorded, which is a real ethical and legal landmine.”
“The direct competitor here is Arc Browser plus any AI extension, or just Chrome plus the Perplexity extension that already exists — and Perplexity already ships that extension. The specific scenario where this collapses is enterprise adoption: IT departments don't swap default browsers for waitlist products, and consumers don't either without a compelling reason beyond 'the sidebar is better.' The prediction: Google ships Gemini natively into Chrome at a depth Perplexity can't match within 18 months, and the browser angle becomes indefensible. For this to earn a ship, Comet needs a capability that is literally impossible to replicate in an extension — and form-filling and summarization are not that.”
“The multi-conversation context linking is where Memoket gets genuinely interesting — it's not just transcription, it's ambient memory. When this works reliably at scale, it's a meaningful step toward the total-recall personal intelligence layer that used to require a supercomputer.”
“The thesis here is falsifiable: the browser is the last surface layer a model provider can own before cloud platforms commoditize the query layer, and whoever owns ambient web interaction owns the monetization stack that replaces the search ad. The dependency that has to hold is that users adopt a second browser for AI tasks — a behavior that has actually happened before with Arc, Brave, and Opera, so it's not implausible. The second-order effect nobody is talking about: if Comet's agent can observe full browsing context across sessions, Perplexity builds a behavioral dataset that no API-layer competitor can replicate, which is the real moat. The trend is browser-as-OS-layer, and Perplexity is early — not on-time, early — which means the execution risk is high but the position is genuinely differentiated.”
“Workshops, client calls, brainstorm sessions — I would wear this constantly. Auto-structured summaries with action items save at least an hour of post-meeting note cleanup, and the cross-session memory linking is exactly what creative project management needs.”
“The buyer here is unclear in a way that should worry everyone: consumers don't pay for browsers, and enterprise won't deploy an unapproved Chromium fork from a company best known for a search sidebar. The pricing architecture is almost certainly 'bundled into Perplexity Pro,' which means the browser is a retention mechanic, not a revenue line — that's fine until you realize the cost of maintaining a browser fork is not trivial and the ROI has to be measured in churn reduction, not new ARR. The moat question is the real problem: Chromium is open, the AI agent layer is replicable, and the switching cost for a browser is extremely high to create but fragile once created. This survives if Perplexity gets acquired by a platform player who needs an AI browser story; as a standalone business decision, the unit economics don't pencil.”
“The job-to-be-done is specific: execute multi-step web tasks without juggling tabs, extensions, and copy-paste loops — and that is a real job that knowledge workers hire for daily. The onboarding question is the one I can't answer from waitlist access, but the make-or-break moment is whether a user can complete a real task in the first five minutes without reading docs, because agentic products that require prompt engineering upfront die in onboarding. The completeness problem is that this requires switching your entire browser, which is a massive ask — Perplexity would have shipped a stronger product by nailing the extension first and using that install base as the migration funnel into Comet rather than leading with the browser. The specific product opinion I'd give them credit for: making the agent persistent and context-aware across the session, not just per-page, is the right call and meaningfully different from extension-based competitors.”
