CallingBox is a YC-backed API that makes AI phone calls a one-liner. You configure a reusable agent with instructions, persona, and tools — then dispatch outbound or inbound calls via a single endpoint. The AI conducts the full conversation, then returns structured JSON matching whatever schema you defined. No managing telephony stacks, STT, TTS, or LLM pipelines separately. At $0.05 per connected minute all-inclusive — covering telephony, speech-to-text, language model, text-to-speech, and data extraction — it's substantially cheaper than stitching together LiveKit, Deepgram, GPT-4o, and ElevenLabs yourself (which their own benchmarks put at ~3x the cost). Sub-500ms latency with a 4.31 MOS quality score makes it production-ready. IVR navigation, voicemail detection, DTMF support, and MCP server integration cover the tricky edge cases that kill most voice implementations. Founded by Jonathan Chávez and Sebastian Crossa, the company offers $5 in free credits to get started. The use cases are obvious and immediate: appointment reminders, collections, customer support, multilingual outreach. For any team that's been putting off voice because of infrastructure complexity, CallingBox removes the excuse.

Clide
AI-native Mac terminal: grid-layout panes, agent that drives your shells

Clide is a native macOS terminal app that rethinks the terminal experience for the agent era. Instead of bolting AI onto an existing terminal, Clide builds around it: an AI pair-developer lives in a side panel alongside a customizable grid of up to 6×6 terminal panes. The AI can read terminal scrollback, preview files, and execute commands into any pane—with user confirmation—making it a genuine collaborator rather than a glorified autocomplete. Built with SwiftTerm, AppKit, and SwiftUI (explicitly not Electron), Clide is genuinely native—fast, memory-efficient, and system-integrated. Drag files from Finder into the AI chat, use the screenshot HUD to share visual context, speak commands via voice input, and rely on workspace memory that persists across sessions. Zero telemetry. Free. What separates Clide from tools like Claude Code or Cursor is its terminal-centric model: rather than AI owning the editor and calling a shell, Clide keeps the shell primary and lets the AI reach into it. For server-side developers, sysadmins, and anyone who actually lives in a terminal, this architecture is more natural and less footprint-heavy than spinning up a full IDE for AI assistance.
Reviewer scorecard
“The single-endpoint design is exactly right — one call in, structured JSON out. MCP server integration means you can wire it to your existing agent tools without rebuilding. At $0.05/min I'd be crazy not to at least prototype with this.”
“Clide nails the architecture: terminal-first, AI as assistant rather than owner. The native SwiftUI build means it's fast and doesn't eat 4GB of RAM like Electron alternatives. Grid panes plus agent control is exactly what I want for complex multi-process debugging sessions.”
“This space is already crowded with Bland AI, Retell AI, and Vapi — all of which have more mature ecosystems and enterprise track records. Vapi in particular has a similar price point and years of production deployments. CallingBox needs a clearer differentiator beyond 'one endpoint.'”
“Day-one Product Hunt launch with 11 followers means this is extremely unproven. The grid + AI concept is compelling but implementation bugs in a terminal app can destroy your work. Wait for a few months of community testing before trusting it with production servers.”
“Voice is still the dominant communication channel for most of the world — banks, healthcare, governments. An API that commoditizes AI phone calls at $0.05/min will unlock workflows that no chat interface ever could. The 113-language potential alone is massive.”
“The terminal isn't going away—it's getting AI co-pilots. Clide represents a category of tools that meet systems developers where they already work rather than pulling them into new IDEs. Native, agentic, terminal-first: this is what the shell looks like in 2026.”
“The structured JSON return is the killer feature from a product design perspective — it means you can embed AI calls in any workflow and get back data you can actually use. Podcasters, researchers, and community managers should all be paying attention.”
“Voice input, drag-and-drop files, screenshot sharing into the AI context—Clide is thoughtfully designed for humans who actually use terminals. The grid layout alone would make it worth trying. Free with zero telemetry is a bonus.”
