1. Opposable Runs Android Computer Use on the Phone With a 2B Model

Opposable (Reval Labs). Opposable is an Android app that reads the screen through the accessibility service and taps and types in other apps on behalf of Claude, ChatGPT or Codex, and now falls back to a fully on-device loop when no cloud agent is connected. The local model is Alibaba’s GUI-Owl 1.5 2B (a Qwen3-VL fine-tune) quantized to 4 bits and run through llama.cpp, about 1.5 GB in total; the vision encoder runs in 236 ms on a Galaxy S25 NPU versus 3.9 s on an M2 CPU. On eight held-out emulator tasks, breaking work into verified subgoals raised success from 4 and 3 runs to 6 in both rounds, though the team says it still trails cloud models on unfamiliar apps and NPU support is limited to Snapdragon phones. The app is free; the post does not state a license for its own code. Blog post

2. Nysa Turns Meetings, Gmail and Calendar Into a Shared Memory Each Teammate’s Agent Can Query

Nysa. Nysa records chosen meetings and syncs Google email and calendar into a team knowledge base of sourced, dated facts organized by topic, which agents (Claude, Codex, Cursor, OpenClaw, Hermes and other MCP clients) read and write through a single MCP server, each signed in as its teammate. Admins define access scopes in plain language (for example HR or Board), and agent API keys can be read-only or limited to projects; existing memory can be imported from GBrain, Obsidian or Markdown folders. Microsoft 365 is not yet supported. Pricing is flat per team: $99/month for up to 10 users, $299/month for up to 25, custom above that, with a 14-day trial. Product page · Show HN

3. Rivinci Hosts MCP Servers Generated From OpenAPI Specs Alongside Deployable Chatbots

Rivinci. Rivinci combines a chatbot builder (choose an LLM provider or its built-in model, set instructions, publish to a website widget, WordPress, Telegram or a streaming REST API) with managed MCP servers generated from existing OpenAPI specs, so the agent can take actions such as bookings or order updates. Either half can be used alone. Rivinci Cloud is in public beta with a free tier (1 agent, 1 server, 1k requests/month), Pro at €29/month and Business at €89/month; enterprise plans add dedicated or on-premise infrastructure.

4. Peras Pauses Claude Code and Codex Before They Exhaust Weekly Plan Limits

Peras (Vertias). Peras reads 5-hour and 7-day plan usage for Claude Code (from the status line) and Codex (through Codex’s local app-server), forecasts whether you will hit a configured line before reset, and then warns, asks for approval on the next tool call, or refuses tool calls until the window resets. Defaults are a notification at 75% weekly usage and a pause at 90%, with per-folder budgets, daily allowances and scheduled pauses available. Everything stays local and the log does not store prompts or commands. The Node CLI is free and MIT-licensed; a macOS menu bar app costs €4.99 once. Product page · Show HN
