Resume UI
Read any past AI session before you resume it. Resume AI Sessions is a split view with a searchable list of every Claude Code, Codex, Gemini CLI and other agent session on the left and a live preview of the project, branch, tool calls and conversation on the right, with replies rendered as Markdown, with Resume, bypass permissions and an editable command one click away.

Why You Need This
How this feature boosts your daily productivity
AI agent sessions pile up fast, and the context inside them is gold — decisions, approaches tried, solutions found. But finding the right session means digging through hidden dotfiles and JSONL logs. Resume UI scans all your local sessions across Claude Code, Codex, and Gemini, and surfaces them in a searchable list with agent badges, project paths, timestamps, and prompt previews. One click resumes exactly where you left off. Even better: select multiple sessions and combine them into a single new conversation, so your agent starts with the full context of everything that came before. No more copy-pasting between terminals to rebuild context.
How It Works
Get started in 4 simple steps
Open Resume AI Sessions
Click Sessions in the top bar or choose Resume AI Sessions… from the app menu. Sessions still running elsewhere are listed first.
Narrow it down
Search titles, prompts and session ids, Group by Date, Project or Agent, and filter by machine and project.
Read the preview
Select a row to see the branch, session id, turns and tool calls (failed ones in red) and the conversation, opened on its last 40 messages.
Resume the way you mean to
Press Resume, or Resume with options… to pick Normal or Bypass permissions, edit the command and see which terminal it opens in.

Why It Matters
The productivity impact of having ai productivity built into your workspace
No More Resume-and-Hope
The preview shows the branch, failed tool calls and the conversation, so you know it is the right session before you spend a context window on it.
One Copy of Each Conversation
Live sessions sit on top, and resuming one offers Close it & continue here or Go to tab instead of a second copy that drifts.
Exactly the Command You Want
Resume with options… sets the permission mode and lets you edit the resume command, and remembers the mode for next time.

Prompt History
Search prompts and sticky notes from Remote Control while away from the desktop. Switch between This project and All projects, filter prompts by agent or notes by source, copy entries, delete with Operator access, and sync local prompt history.
Combine Sessions
Merge several past AI sessions into one opening prompt, or hand a single session to a different agent. Tick sessions in Resume AI Sessions, see a token estimate of the context they add, and send the result to a new chat with any agent or preset or to a terminal that is already open.
AI Diff Review Panel
Track every file modification any AI agent makes — Claude Code, Codex, Gemini, Amp, custom — and review, accept, or revert their work per file from a dedicated panel with inline diff overlays in the editor.
Screenshot Annotator
Annotate screenshots and embed them directly in your AI prompts for visual context.
