Martin Alderson applies web performance principles to AI agent workflows, covering time to first token, prompt caching and other factors that affect how fast agents complete tasks.
xAI's Grok Bot signs in to your tools and uses them like you do, taking projects from start to end and coming back when your approval is needed. Available for macOS and iOS.
Launch post explaining what Strands Harness does: a customisable, state-of-the-art agent you run locally or deploy anywhere, with a claim of 28% lower token cost than comparable stacks.
Why I recommend it: Free to read. Treat the token-cost figure as the vendor's own benchmark, not an independent one.
Open-source SDK, Python and TypeScript, for building production AI agents you run yourself — any model, any cloud.
Why I recommend it: Free and open-source (Apache-style OSS). For builders who want an agent framework they control, not a hosted service.
Personal AI agent you text or call. It reads your email, calendar, screen, and messages and takes actions across apps — booking rides, contacting handymen, sending emails on your behalf.
Why I recommend it: Invite-only beta, free today, no published price. Read the terms before you connect anything: it is legally your agent, so actions it takes can bind you as if you did them yourself. Reports of surprise cancellation fees and unauthorized emails; do not give it your credit card, calendar, or work email without understanding what it can do.
Monitoring for AI agents in production. Traces every run and tool call, groups repeated failures into one issue, and simulates a change on a pull request before you merge.
Why I recommend it: Free tier available; paid plans start around $150/month. Built for engineering teams shipping customer-facing agents — not something a job seeker will use, but useful if you build with AI.
Free open-source video and motion editor for Apple Silicon Macs. Connect a coding agent (Claude Code, Codex) to rewrite panels, effects, and extensions inside the running app.
Why I recommend it: macOS only, requires an Apple Silicon chip. Free and open-source; extending it means running your own coding agent, so the useful audience is people already comfortable in code.
