Grok Bot turns your computer into a mini company: agents with roles in a Telegram-style chat

By Rafa, solo edition · Café con Codely · Javi is on vacation

The xAI and SpaceX team launches Grok Bot. It is a general-purpose agentic assistant, not made for coding. It lives in a Telegram-style chat interface. There you build your mini team: one role for sales, one for expenses, one for the inbox.

Grok Bot controls your computer and learns tasks by watching you. You show it how you enter Salesforce and where you click, and it repeats that task for you. The inbox manager is the star example: you teach it what you consider spam, and it filters the hyper-personalized emails that AI now generates at scale.

The curious fact: SpaceX did not build this from zero. Cursor built it internally and had it ready to launch. After SpaceX bought Cursor, they rebranded it to Grok Bot. Rafa speculates about a possible rename of Cursor to Grok Code: OpenAI already took Codex.

The precedent is OpenClaw, which peaked in March and nobody remembers today, according to Google Trends. Grok Bot will not repeat that boom: the entry barrier is 200 dollars per month. But it sets a precedent for simplicity and puts pressure on products like Claude Cowork. Watch in the video.

Anthropic adds invisible watermarks to Claude's text: the pattern hides in the synonyms

Claude starts to add invisible watermarks to the text it generates and metadata to the files it touches. It responds to a European Union obligation: you must be able to know if AI made a piece of content. Thariq, from the Claude Code team, confirms that Anthropic will give an API to verify if Claude generated a text. OpenAI and Google have the same obligation; Google was the pioneer with SynthID.

Alex Cui, from GPTZero, explains the two techniques. The simple one adds invisible Unicode characters, and a strip removes it. The robust one classifies words into two blocks with a secret key and plays with synonyms to form a statistical pattern. The viral tool Watermark Remover, with 6,000 stars on GitHub, cannot remove that second mark: it only generates a prompt so another model rewrites the text. If you use a weak local model, you lose quality. The law also applies to open source models, and Rafa fears an EU war against them. Watch in the video.

You can no longer afford bad programmers: AI also multiplies downwards

A post from this week sums it up: AI is removing the middle class of software engineering. It is 2026, you are the most senior person on the team, and on a normal Monday you find seven PRs to review. The first one adds 24,000 lines and removes 3,000, with an AI-generated description. Your team made more changes since Friday than before in whole weeks.

AI turns the 1x engineer into 10x and the 10x into 100x. But whoever lacks the foundations goes from 0.5x to 0.05x: a multiplier that subtracts more than it adds. The post's analogy: the difference between crashing at 30 km/h and crashing at 200. Software architecture matters more today than ever. Senior engineers are lucky: they learned by writing code through trial and error, an experience that is now almost impossible to get. Watch in the video.

The utility of the week

Crest

Another native Swift browser as an Arc alternative, after Viola two weeks ago. It is based on WebKit instead of Chromium, a decision Rafa does not share: most websites are made for Chromium. In exchange, it is the first one that brings the Arc-style sidebar to its mobile app. Rafa has not tried it yet, but it looks very promising.

The chat weighs in

LuisJavierPeris: The date the law takes effect depends on company size: it already applies to companies with more than 250 employees. But not yet in Spain, which delayed it to January 1 next year (what a surprise!)

josemeseguer2347: I disagree, Rafa. It is not harder at all — the opposite: you can prepare better than ever. But now we want everything NOW and EASY

Einhasad: The session-to-session communication could be used for a back + front feature: they talk to each other so one builds the endpoint and passes the contract to the other…

The song of the week

Rafa: «Como Camarón» — Estopa (He played it last week, and they forgot to comment on it. A true classic: you do not even need to play it, just thinking about it makes it sound. Estopa marked a generation.) Watch in the video.

The saying of the week

«For the unlucky, every day is Tuesday»

Spanish saying («Para los desgraciados, todos los días son martes» — Tuesday is the unlucky day in Spain). It applies to people who suffer adversity all the time. Rafa preferred the Portuguese variant: «The unlucky one falls on his back and breaks his nose». Watch in the video.

Spec-Driven Development con Research, Plan, Implement

Now 100% published. The work methodology to get medium and complex features right on the first try: you make the plan, review it at one point, and avoid deviations, without orchestrating three agents in parallel or burning tokens.

The joke of the week: The code editor that Valencians use is Nano. Vim is forbidden there. (In Valencia, «nano» is slang for «buddy».)
