How it works
Three steps. Minimal drama. Your browser thanks you.
Install from your store
Add Sidecar from Chrome Web Store, Edge Add-ons, or Firefox Add-ons. (Links are placeholders until you ship.)
Enable it on ChatGPT
Open ChatGPT and toggle Sidecar on. If it’s enabled, it’s available. No pinning ritual required.
Run macros + commands
Use Ctrl+K to open the command palette. Save macros, replay flows, and keep your hands on the keyboard.
Macros that actually help
A command palette + macro store designed to automate your workflow without hijacking ChatGPT’s composer.
Command Palette (Ctrl+K)
Type commands in Sidecar’s palette input only. No slash-command hacks in the native composer, no IME breakage.
Macros + Flow Scripts
Save, share, publish, and run macro automation scripts that feed into your Flow engine (flow.ts).
Terminal-like History
Up/Down cycles your recent commands like a shell. Persisted in chrome.storage.local and capped to keep it sane.
Token estimates, lazily
Cache per thread, refresh in idle time, and avoid re-tokenizing the universe on every mutation.
Roadmap bits (the “nice to have” pile)
A few of the bigger upgrades that fit your spec. These are landing-page bullets, not promises.
Page title cleanup
Strip “ChatGPT - ” from the tab title when running in the extension context.
Popover UX
Popovers close on outside click and on actions inside them.
Grab handle animation
Cute micro-handle that expands on hover and animates smoothly.
Prompt recall in composer
Up-arrow previews recent prompts; Right-arrow inserts full prompt.
Scroll + wide mode safeguards
Stop auto-scroll to bottom optionally; fix wide-mode overflow on long prompts.
Message collapsing
Collapse long chats with preview + char count; auto-collapse on send over X chars.
Your code blocks
Detect ``` in your messages, render styled blocks, syntax highlight, click-to-copy.
Font scaling
Scale Sidecar UI without changing browser zoom.
