The deck your agents work on.

Terminal

Every tab is a shell. Every shell survives the tab.

A real terminal multiplexer in the browser: sessions keep running when you close the tab, reattach from any device on your tailnet — the phone included. The grid shows every session live, so a wall of agents is one glance.

• Detach / reattach — close the laptop, pick the session up on your phone.
• Status glyphs — running, needs-you, idle: triage the deck without reading a line.
• Live grid — every session as an interactive tile, not a static preview.
• Claude usage quota — session + weekly budget bars right in the grid header.
• Automations & webhooks — schedule commands, trigger on git events.
• Worktrees, secrets, pinned REST sessions — inherited from a great upstream.

Click-to-preview

Every file path in output is a link.

Your agent prints report.md, dashboard.html, src/search.ts:42 — in TermDeck those are links. Click one and it opens rendered in a drawer beside the terminal: Markdown with typography, code with syntax highlighting jumped to the line, CSV as tables, images, PDFs, HTML as the actual page. The terminal never moves.

agent prints paths → click → rendered markdown → click code path → line 42, highlighted

• Works for any program — it's the terminal linkifying, not the agent: git, pytest, ls, anything.
• Line jumps — file.ts:42 opens the source scrolled and highlighted at 42.
• Drawer, not navigation — layover or split; the session stays mounted underneath.
• GitHub links too — issue/PR URLs render as fetched markdown in the same drawer.

Tweak mode

Point at the pixel. The agent gets the selector.

The drawer renders HTML — a vault file or your deployed app through a same-origin proxy. Toggle Tweak and the page becomes an element picker: click the thing that's wrong, type what should change, and TermDeck sends the agent a structured message — robust CSS selector, element snippet, your note — straight into its terminal session.

render dashboard.html → tweak mode → pick element → note → batch → “Send 2 tweaks”

• Send now or batch — stack up tweaks in a tray, send them as one message.
• Linked session routing — feedback lands in the session that produced the file, or spawns a fresh one.
• Remote deploys too — a clicked deploy link previews framed in the drawer, picker injected.
• Text selections — highlight prose in any rendered doc and “chat about this” the same way.

Wiki

A reading room for your Markdown.

The same daemon serves your notes as a wiki: serif reading surface, frontmatter panel, reading stats, full-text search, filters, and Obsidian [[wikilinks]] that resolve. Editing is WYSIWYG with slash commands — frontmatter preserved verbatim, markdown round-trips losslessly.

• Renders 25+ file types — md, code, CSV, images, PDF, video, HTML, diffs.
• Mermaid everywhere — ```mermaid fences render as live diagrams in every surface.
• WYSIWYG + slash menu — Notion-style blocks over plain files; source mode one toggle away.
• Reading mode — chrome melts away; Esc brings it back.

Canvas new

An infinite whiteboard, offline, in the same tab.

The third mode is a tldraw canvas — fully offline (assets bundled, document in IndexedDB, no accounts, nothing leaves your machine). And it understands what you paste: mermaid source becomes a live diagram, a Markdown doc becomes a rendered card — tables, code, and embedded charts included.

paste a markdown doc → rendered card with table + live mermaid flow

paste bare mermaid → a diagram shape; double-click to edit the source in place

• Paste-aware — mermaid → diagram, markdown → card, plain text stays plain.
• Double-click to edit — the source reopens in place; the render updates on commit.
• Theme-synced — follows the same light/dark toggle as the terminal and wiki.
• Local-first — survives reloads via IndexedDB; zero network requests.
