Reely turns an app feature into a finished launch video — from inside your own AI coding agent. Bring screenshots or a screen recording and Reely builds the video around them. Or, on native SwiftUI, stay in your agent (any MCP host): it authors a faithful mock of your feature and hands it to Reely’s engine, which builds, drives the Simulator, records, composites the look, and opens the finished video in the Reely viewer.
“Make a launch video of the onboarding flow.”
Authors a mock + FeatureAdapter + FlowSpec (your key, no LLM cost to us).
build → Simulator → drive → record → composite → opens the viewer.
The authoring half is the LLM’s job. The rendering half is Reely’s deterministic engine, which your agent runs locally — no reel footage or source ever leaves your Mac.
Reely is a macOS app that runs on your local Xcode + iOS Simulators. Setup is three parts: download and activate the app, set up your agents (once per machine, or once per repo), then generate reels by asking your agent.
claude), Cursor, VS Code, Codex, or Gemini CLI.Download Reely from the website, drag Reely.app into your Applications folder, and launch it. No account or license key is needed to start — creating reels is free and unlimited.
A subscription is required only to export the finished video. When you are ready, click Activate Reely and paste your license key. Projects you built before subscribing stay on your Mac and can be exported afterwards.
The reely engine ships embedded inside the app. Once activated, the welcome screen shows a Set up agents card — this both installs the engine and wires it into your coding agents (Claude Code, Cursor, VS Code, Codex, Gemini CLI…) in one step.
The picker lists every agent it can detect on your Mac — the found ones are pre-selected. Pick the agents you want, then choose a scope: Install Globally (every project) or Install for a Project… (one repo). You’ll be asked for your password so the engine can be placed on your PATH.
| Scope | What it does |
|---|---|
| Install Globally | Unpacks the engine to /usr/local/bin/reely and wires each selected agent for every project — e.g. for Claude it registers the reely MCP server in ~/.claude.json, pre-approves mcp__reely__run_reel, and copies the authoring skill into ~/.claude/skills/. |
| Install for a Project… | Pick an iOS project folder; the engine is installed and each selected agent is wired into that repo — writes the agent’s MCP config, pre-approves the tool, copies the skill, and materializes the recording scaffold under .reely/. |
All writes are non-destructive — existing MCP servers and permissions are preserved. Global install covers everything; choose per-project only if you’d rather not touch your global agent config.
Open your iOS project in your agent and ask for a reel — the /reely skill authors a faithful mock of your feature and hands it to Reely’s engine, which builds, drives the Simulator, records, and composites the look:
Make a launch video of the onboarding flow.When it finishes, the reel opens automatically in the Reely viewer. To confirm the wiring first, check your agent’s MCP servers — you should see reely connected (in Claude Code, run /mcp).
Each case is a real prompt you’d type to the agent, and the reel it produces. Go from all-defaults to a fully branded, captioned iOS launch reel just by changing what you ask for.
/reely Make a launch video of the onboarding flow.
The baseline. The skill authors a brand-faithful mock of your feature, then renders a clean reel with the standard look — a padded canvas, auto-zoom toward each tap, and dead-air cuts. Nothing else to steer.
/reely Make a reel of onboarding with captions that explain each step.
Ask for captions and the agent becomes the copywriter — it writes a short line for each key step and they appear as lower-third captions, synced to the action. You describe the intent; the wording is written for you.
/reely Make the reel and brand it with our app’s colors and font.
Ask Reely to brand the reel and it pulls the background, caption palette and contact shadow from your app’s colors — and swaps the captions into your app’s own embedded font.
/reely Brand the reel from our shipping MyApp.app.
Point Reely at your real shipping app and it extracts the true palette and icon from it — so the reel matches exactly what users install, not a stand-in.
/reely Use Avenir Next for the captions.
Ask for a specific typeface and Reely sets the captions in it.
/reely Record the reel on an iPhone SE.
Name a device and Reely records on that Simulator instead of the default iPhone 16 Pro. Keep the device-native portrait canvas or ask for 9:16 vertical or 16:9 horizontal output.
/reely Make a reel of onboarding — match these screenshots. [attach screenshots]
Attach screenshots of the real screens to maximize the fidelity of the reel.
