Deckpipe inverts the standard slide creation workflow. Instead of an AI helping a human build slides, agents describe slide content as JSON and Deckpipe renders it into polished visual presentations. The tool runs as a native MCP server, meaning any Claude, GPT, or open-source agent can drive it directly without custom integration. The key innovation is the feedback loop: agents can read viewer comments and analytics from Deckpipe and iterate on slides without human intervention. A sales agent can create a pitch deck, send it to a prospect, read which slides got attention and which were skipped, then revise the deck before the follow-up call — all autonomously. Deckpipe supports templating, brand guidelines, and multi-format export (PDF, web, live presentation). It launched on Product Hunt today with a focus on teams that want to automate reporting and proposal generation pipelines.

Walkie is a Mac and Windows dictation app that turns any text field into a voice interface. Hold your hotkey, speak naturally, release—and your words appear in whatever app is active: Slack, VS Code, Gmail, Terminal, Notion, anywhere. The app runs on-device using your choice of 7+ local models (Whisper variants, NVIDIA Parakeet, Moonshine, SenseVoice) or can optionally route through cloud servers with a zero-data-retention policy. The differentiation from basic OS-level dictation is the AI post-processing layer: Fast Mode removes filler words ("um," "uh"), fixes grammar, and adapts formatting style based on context (formal, casual, technical). A custom dictionary learns your domain vocabulary—medical terms, product names, variable names—and a snippet system lets you trigger full text expansions with voice shortcodes. Launching on Product Hunt today (April 6, 2026) with 107 upvotes, Walkie sits at #6 on the daily leaderboard. The free tier is genuinely useful: unlimited local mode plus 4,000 Fast Mode words per week. Pro is $6/month for unlimited Fast Mode and advanced smart commands. It supports 100+ languages via Whisper.
Reviewer scorecard
“The MCP-native design is the right call for 2026 — agents already generate reports and summaries, they just don't have a clean way to turn them into presentations. The JSON-to-slide abstraction is simple enough that any coding agent can use it without a tutorial. The viewer feedback loop for autonomous iteration is genuinely new.”
“Six dollars a month for unlimited voice-to-text across every app on my machine, with local processing as the default and filler word removal baked in. The snippet trigger feature alone is worth the price—I can say 'insert boilerplate' and have it expand a 200-word block. This is the Raycast of dictation tools.”
“The vision of fully autonomous slide creation is compelling but the reality is that visual design requires taste that current AI agents lack. Agent-generated slides still look like agent-generated slides — formulaic, safe, and visually generic. Until the rendering layer improves dramatically, you'll want a human in the loop for anything customer-facing.”
“Whisper-based dictation apps are practically a commodity at this point—Flow, Superwhisper, and even native OS dictation do most of this. The AI post-processing is nice but adds latency. And I'd want to see the 'zero data retention' claim independently audited before routing sensitive voice data through any cloud tier.”
“Deckpipe represents the shift from AI as a productivity assistant to AI as an autonomous business function. When agents can create, send, analyze, and iterate on presentations without human involvement, entire reporting and business development workflows get automated. This is early infrastructure for the agentic enterprise.”
“Voice is the natural input layer for the agentic era—when agents can act on your behalf, you want to direct them by speaking. Walkie's voice command integration points toward this: not just dictating text but triggering OS-level actions by voice. The local-first model is also a meaningful privacy signal as voice data becomes more sensitive.”
“The viewer analytics feeding back into agent iteration is the feature I didn't know I wanted. Understanding which slides land vs. fall flat — and having that data automatically inform the next version — is what distinguishes this from every other 'AI makes slides' tool. This is data-driven design, not just automation.”
“As someone who writes 5,000 words of content a week, I've been burned by cloud-dependent voice tools going down at the worst moments. Walkie's local mode with 7 model choices is exactly what I need—reliable, fast, private. The snippet expansion feature for my frequently-used phrases is a genuine time saver.”
