In their own words
Claude
Claude is an AI assistant built by Anthropic to help users with work. It is available on web, Android, iOS, macOS, Windows, Linux, through an API and as an extension. Claude can search the web, accept file uploads, create and edit spreadsheets, presentations, Word documents and PDFs, and analyze data using code execution. It can also create and share documents, dashboards, diagrams and interactive tools as artifacts; artifact storage is limited to 20 MB and text only. Connectors can link Claude with services including Asana, Linear, Notion, PayPal, Square, Plaid, Intercom, Zapier and Workato. Research, available on paid plans, runs multiple searches and returns answers with citations. Usage limits reset on a rolling five-hour window, and paid plans have additional weekly limits; usage also varies by conversation length, model and features. The Free plan includes limited usage and up to five projects. Pro costs $20 a month or $17 a year, billed $200 up front. Team plans add central billing and administration; Enterprise includes further access controls.
Tandem Browser
Tandem Browser is a free, MIT-licensed browser in developer preview for running AI agents alongside a person’s browsing session. Agents share tabs, cookies, and the DOM, and can work with the accessibility tree, rendered DOM, network requests, console output, and DevTools. If an agent reaches a CAPTCHA, unclear form, or judgment call, it pauses for user help. MCP- or HTTP-speaking agents can connect locally or through a private Tailscale network, with separate workspaces and tab locks. The documented API includes more than 280 HTTP endpoints and 257 MCP tools, protected by bearer tokens. Tandem has no cloud backend, subscription, or telemetry according to its FAQ; browsing data remains on the machine unless sent elsewhere. It can run offline with Ollama or LM Studio. Daily-driver features include extensions, bookmarks, history, a local password vault, workspaces, and sidebar apps. It uses Chromium and supports macOS Apple Silicon, Windows 11 x64, and Linux on a best-effort basis.
