Circleback now has a free plan, and full API and MCP access starts at 15 dollars

The meeting note-taker replaced its lineup with four tiers: Free, Pro, Business and Enterprise. The free one records and transcribes without a cap on the number of meetings and keeps 30 days of history, and the release note says it is a plan rather than a trial. What it withholds is full access to the API, the Model Context Protocol server and the command-line tool. Those begin at $15 per user per month, which is where the line now runs for anyone feeding transcripts into an agent.

Simon Willison counted what ChatGPT Work actually has: 223 tools, 44 skills, open internet access

Willison reports that OpenAI announced ChatGPT Work on July 9, 2026 and has been changing it since, without documenting what the agent can do. He spent weeks testing it, then had the product describe itself: 223 registered tools and 44 skills, six of the tools his own. The inventory shows a code sandbox with open internet access, a full headless Chrome, and a filesystem shared across sessions.

Anthropic opens 10,000 Claude seats to scientists, free or $15 a month

Anthropic announced a Claude team plan for scientists on August 27: 10,000 seats worldwide for one year, standard seats free and premium seats with 5x usage limits at $15 per month. The plan is claimed by a principal investigator, who then adds their lab. Separately, the AI for Science program now takes researchers outside biology and grants up to $50,000 in credits per project. Access to models is not uniform, and the exceptions are the part worth reading.

Claude Cowork gets its own browser, deliberately separate from yours

When a task needs a website, a browser opens in the side panel of the desktop app and Claude drives it. Anthropic's design decision is the whole story: it is Claude's browser, not the user's, so it never sees their tabs, bookmarks or passwords. Rolling out to Pro, Max and Team over the week from August 26.

Claude in Chrome is generally available, and it now clicks without asking first

Claude in Chrome has left the pilot and is available on every paid Claude plan. The change that matters is not availability but autonomy: Claude now approves safe actions itself, using the same mechanism as Claude Code, instead of stopping for every click. Anthropic published the prompt injection numbers behind that decision, and the one worth reading is the baseline: before extra safeguards, attacks that reached Opus 5 succeeded 3.8% of the time.

Claude's memory is now one memory, shared between chat and Cowork

What Claude learns in a conversation is what it knows in Cowork, from August 25 on web, desktop and mobile. Memories are listed by topic in settings, each one can be edited or deleted, and sensitive categories stay out unless you let them in.

ChatGPT now reads and sends your Apple Messages, on the Mac only

A plug-in in the ChatGPT desktop app reads and searches your iMessage, SMS and RCS threads and sends messages through Messages on your behalf, but only in Codex and in ChatGPT Work, not in ordinary ChatGPT chat. By default nothing goes out until you approve both the text and the recipients. There is a switch that removes that step, and OpenAI's own documentation argues against using it.

Gemini Spark vs Claude's browser toolset: whose account, whose risk

Both drive a web browser, both stop before the step that cannot be undone, and their lists of stopping points are nearly the same. The difference is what each assumes about the session it runs in: one is built on the accounts you are already signed into, the other tells you to give it a browser with no credentials in it. That single assumption decides which of the two belongs anywhere near your work.

Gemini Spark takes over desktop Chrome

Google's agent can now drive the desktop version of Chrome, using accounts you are already signed in to and passwords saved in the browser. It books property viewings, prepares flight searches, and fills in forms, handing the task back to the user to finalize a payment, accept terms, or create an account. This is the same pattern that has settled in with Claude and the rest: the agent does everything up to the step that cannot be undone, and a person confirms that step.
