Get it for macOS

Opens Excel, Word, PowerPoint, PDF, images and video right in BB's side panel, on any device you browse from. Spreadsheets recalculate live formulas and save edits to .xlsx and .csv without touching the formatting. Pictures open in an editor for arrows, boxes, text, numbered steps, blur and crop, and the result goes straight into the chat. Select cells, a PDF passage or a slide and quote it to the agent. Runs locally: no account, API key or external service.

What you get

Office Viewer opens spreadsheets, Word, PowerPoint and PDF documents, images, videos and audio in BB's side panel: .xlsx, .xlsm, .xlsb, .xls, .ods, .csv and .tsv, from chat links, the file picker and bb thread open.

  • A familiar grid — column letters, row numbers, a frozen first row, right-aligned numbers and merged cells.
  • Big sheets stay fast — only the visible part is drawn, so thousands of rows scroll smoothly.
  • Values as in Excel — number and date formats from the file; the cell bar shows the full value and the formula.
  • Search — find text anywhere in the sheet and step through matches with Enter.
  • Links and copying — ⌘-click opens URLs from cells; copy any selection with ⌘C.
  • Quote in chat — select cells, right-click and send them to the agent as a table with the file, sheet and range, plus your comment.
  • Edit without losing formatting — change .xlsx and .csv files in place. Only the edited cells are rewritten, so styles, conditional formatting, comments, charts and macros stay exactly as they were.
  • CSV that just works — comma, semicolon or tab separators; UTF-8 or Windows-1251 text.

Word documents

.docx opens as Word-like pages with styles, tables, pictures, headers and footnotes, fitted to the panel width. The legacy .doc shows its text. Download the original with one click.

Search the text (⌘F), zoom, and quote a selection into the chat.

PowerPoint

.pptx, .ppsx and .potx open as slides with thumbnails, keyboard navigation, full-screen presenting, speaker notes and a Quote in chat button that sends the current slide's text to the agent. The old .ppt can be downloaded only.

PDF

.pdf opens as a continuous scroll with zoom (fit width, fit page, ⌘ +/−/0), a page box to jump to a page, text search with highlights, selectable text and Quote in chat for the selection. Password-protected files ask for the password. Download with one click.

Images, videos and audio

Pictures, GIFs, SVGs and videos (.png, .jpg, .gif, .webp, .svg, .mp4, .mov, .webm and more) open with Download to the device you're on and Copy to the clipboard for images. Images zoom, pan and step through their folder. Edit marks a picture up — boxes, arrows, text, numbered steps, highlighter, blur, crop, rotate — and saves a copy, overwrites it, or sends it to the chat. Videos get speed, repeat, frame steps, picture in picture and Frame, which opens the current frame in the editor. Videos play and seek in any browser, iPhone and iPad included. Audio (.mp3, .wav, .ogg voice messages, .m4a, .flac and more) opens in a player with a waveform, stop, ±10 s, repeat, volume and speed 0.5×–2×.

Machine-aware files

A file is read on the machine of the thread, environment or project it came from, whichever device you browse BB on.

Requirements

BB 0.43 or later. No account, API key or external service. Files up to 30 MB; .xls, .xlsb and .ods open read-only. The interface is Russian when BB's language or the browser's first language is Russian, English otherwise.

Agent ToolsShow which MCP servers and skills each BB machine actually has, then bring them to one catalogue and one canon. A matrix marks present, missing, and drifted configs; new servers wait for adopt, keep-local, or hide. Sync adds what is missing and never deletes on its own. The Skills tab treats ~/.agents/skills as a git canon, with fan-out into CLI homes and a version archive. Writes back up each config first; loopback paths and local secrets stay on that machine. Optional MetaMCP listing needs that gateway's API key.NewCLI AgentsStart each chat with a specialist agent or selected profile instructions. Choose native Claude Code and OpenCode agents, or Codex profile developer instructions (up to 4096 characters; other profile settings are not applied), on local or enrolled remote machines. Requires BB 0.43.x on macOS or Linux and an installed, authenticated supported CLI; provider subscription limits or API charges apply.NewEnv CatalogStore API keys, tokens, and secrets in a single encrypted catalog across all BB sessions and machines. Securely request credentials via masked in-app modals. Agents automatically check available credentials before prompting you, and persist newly provided keys on demand. Values are encrypted at rest with AES-256-GCM and synchronized via your central BB server. Includes dedicated agent tools, a full-featured management UI with .env import/export, and terminal CLI commands.28File GatewayBrowse files across your BB machines and FTP/SFTP website accounts, then add a native file mention to a chat so the agent opens the correct source and path. Read text or download files without exposing account passwords to agents. Requires connected BB machines or reachable website accounts; macOS/Linux, read-only website access, 256 MiB between BB hosts and 32 MiB from websites. English interface with drag-to-chat mentions, hidden-file controls and native file preview.New

File ManagerManage the files on the machine bb runs on without a terminal: browse, upload, move, rename, extract and hand them to the agent. Opens as a sidebar page, as a tab beside a thread that can start in that thread's folder, and from a file link in a message. Double-click shows images, PDF, video, Markdown and code; Space looks inside zip, tar, 7z and rar archives without extracting them. Multi-gigabyte uploads resume after a dropped connection. On a phone, selected rows get an Actions bar with the whole row menu. Access stays inside the home folder of the user bb runs as; tar, 7z and rar archives need tar and 7z on that machine.Foma421
FilesA VS Code-style file explorer and editor for the workspace behind a thread. Search in files finds a word across every file in the project: results are grouped by file with each hit highlighted, and clicking one opens the file on that line. It is smart case, with match-case, whole-word and regex toggles, and built for typing — file contents stay in memory between searches, so refining a query re-runs in tens of milliseconds, and a regex runs in its own worker so a runaway pattern cannot freeze BB. Around it: a file tree that shows dotfiles, editor tabs, a go-to-file palette (Cmd+P), find in the open file (Cmd+F), syntax highlighting in your BB code theme, and edit and save guarded so a change an agent made underneath you is never clobbered. Markdown files open rendered, with the source and the editor one click away. Two pickers choose the project and then its checkout or one of its worktrees; beside a thread it is pinned to that thread's worktree. Adds a `bb files` command so agents can browse and read the same workspace from the CLI, on whichever machine it lives.AbdElrahman Telb288
