Checked 11 November 2026, Europe/London. Two developments announced on 10 November offer practical choices for small teams: shared working documents in Claude and wider access to Google’s Carbon model.
Claude adds shared boards and sheets, with beta limits
Anthropic announced Claude Whiteboards and Sheets in beta on 10 November, available on all paid plans across web, desktop and mobile. Claude Dashboards also becomes generally available as Claude Data, although certified queries and live sharing remain beta features.
Whiteboards supports collaborative planning; Sheets can create and edit spreadsheets, including formulas and formatting. Anthropic says Sheets currently provides simple spreadsheet functionality, with .xlsx and CSV export when users need other tools. Claude Data requires a data connector. On Team plans, all three are enabled by default. Enterprise Whiteboards and Sheets start disabled, while Data is scheduled to turn on by default on 19 November.
Tecrave analysis: an existing paid user could try a small campaign tracker or project handover before adding another collaboration subscription. Check formulas, exported files and sharing permissions before relying on the result. This is a workflow expansion, not evidence that a beta spreadsheet can replace every Excel process. The announcement does not specify a separate feature price.
Gemini 4 Carbon opens more broadly, with introductory prices
Google’s 10 November announcement expands Carbon beyond its earlier restricted cybersecurity release. Paying developers and enterprises can access it through the API in Google AI Studio and Gemini for business. Google AI Ultra subscribers are also receiving access in the Gemini app, Antigravity and AI Mode in Search.
The public-access model’s introductory API rates are US$2 per million input tokens and US$10 per million output tokens. After the introductory period expires on 30 November 2026, Google says US$4 and US$20 respectively will apply. Google positions Carbon for demanding, extended tasks and says Argon remains suitable for most software engineering and knowledge work. Carbon can consume more tokens.
Tecrave analysis: a small software firm could assess Carbon on a difficult debugging task, with a spending cap and a checked result. Budget using the later rates and actual token consumption. Google’s capability and cost-performance assertions are vendor claims, not Tecrave test results.
