BonsAI v1.3.0

Hi guys! We’ve gained a lot of stars and downloads lately, thanks for all the support!

This is a huge release, and I hope you enjoy it. Although the previous UI was great and beautiful, it had some tradeoffs because it wasn’t a real window. So, among the super cool new features, fixes, and improvements, this release also brings real value for the future things we can do.

Thank you,
Jonatas Walker

Added

• A calmer standard window workspace. BonsAI now opens as one resizable macOS window with the
  board, Agent, Settings, board switcher, tools, zoom, and grounding controls arranged as floating
  canvas chrome instead of separate side rails and history panels.
• Codex and OpenCode join the streaming agent. The in-canvas chat agent now runs on Codex
  (codex exec --json) or OpenCode (opencode run --format json), not just Claude. Pick one from the
  new engine chip on the Agent panel's composer row — it appears whenever two or more engines are
  ready. Each engine reaches the same board over the loopback canvas MCP server, keeps its own session
  for follow-ups, and streams replies and tool calls into one shared transcript. See
  docs/agent-engines.md.
• OpenCode as a one-shot engine. OpenCode joins Claude and Codex on Refine / Compile,
  toggleable in Settings ▸ Runtime ▸ Engines and gated on the opencode binary being installed.
• Writing on the canvas feels like writing. Text cards now live-render Markdown headings, bold,
  italics, code, quotes, lists, and checkboxes while keeping the plain text source intact for agents.
  Cards at rest render the formatted version, the selection bar can apply common Markdown actions,
  and Focus Mode expands the active card into a centered writing sheet.
• Themes and element colors. Appearance settings now offer BonsAI Dark, BonsAI Light,
  Catppuccin Mocha, and Catppuccin Latte previews. Canvas element colors are theme-relative, so a
  selected tint follows the active palette instead of hard-coding one color value.
• Better drawing controls. Holding Shift while drawing or resizing rectangles, ellipses, and
  diamonds constrains them to square/circle/uniform proportions. The bottom color swatch now colors
  new elements and can retint the current selection.
• The linter's clarify escalation follows your chat engine. The ambiguity popover's escalate
  button was hardcoded to Claude; it now runs on your resolved Chat Agent engine and shows that
  engine's logo — "Refine with Codex" / "Refine with OpenCode" — so a non-Claude setup no longer
  silently reaches for Claude (and the row hides when no engine is installed).
• Provider + model for the chat agent. Both Settings ▸ Models and the Agent panel now read as
  pick a provider, then a model: Claude keeps its Opus/Sonnet/Haiku tiers; OpenCode lists its live
  opencode models catalog; Codex offers the model from your ~/.codex/config.toml. Each is passed
  to the CLI (--model / -m). Codex now honors your configured model again — the chat runs it with
  --ignore-user-config (to protect canvas MCP startup), which had been dropping it — and the
  one-shot Codex path gained --skip-git-repo-check so Refine / Compile work from any folder.

Changed

• Runs on macOS 14 (Sonoma) and up. The minimum was lowered from macOS 26 (Tahoe); the board and
  every core feature work throughout. Tahoe-only extras — the Apple Intelligence semantic linter and
  screenshot cleanup, plus the Liquid Glass look — stay gated and quietly turn themselves off below
  macOS 26 or when Apple Intelligence is unavailable, so nothing shows a broken control or a
  missing-glyph icon on older systems.
• The welcome canvas was refreshed for 1.3.0. New and existing users get the new Welcome Canvas
  with a smaller bundled image asset that resolves through the app bundle instead of a stale local
  attachment path.

Fixed

• Canvas MCP registers reliably for strict clients. The MCP handshake (initialize /
  tools/list / ping) is now answered off the main thread; only board mutations hop to it. An
  agent CLI with a short startup handshake window (Codex) no longer intermittently fails to see the
  canvas tools while the UI is busy.
• Newly added engines light up on their own. The runtime-availability cache used to restore its
  saved snapshot verbatim, so an engine added in an update (OpenCode) stayed stuck on "Checking…" —
  invisible to the agent picker and refine bar — until you hit Recheck. It now detects any engine the
  snapshot doesn't cover on launch.
• Japanese and other IME input no longer breaks in the canvas editor. While composing marked text
  (Japanese / Chinese / Korean, or dead-key accents), the editor was reformatting the half-composed
  text and could steal the Return that confirms a candidate, so characters dropped or the wrong
  reading was committed. Composition is now left untouched until it commits.
• Single-click selects text cards again. Text blocks no longer jump straight into editing on a
  normal click; single-click selects/moves the card, and double-click enters text editing.
• The board switcher no longer fights macOS window controls. The top-left board picker now sits
  in its own lane away from the traffic-light hit boxes.
• Settings model pickers no longer crush their labels. The Models row keeps readable copy beside
  the provider/model menus, and falls back to stacking the controls when the panel is narrow.
