To get started, you need a Mac, Xcode 16.4+ (iOS 17.0+ deployment target), and a (free) Apple Developer Account.

1. If your Xcode installation is fresh, make sure that command line tools are selected:

   sudo xcode-select --switch /Applications/Xcode.app

2. Install the tools needed to build the project:

   brew install xcodegen swiftformat swiftlint

   (If you don't have Homebrew, see their official install instructions.)

3. Download the llama.cpp XCFramework (required for on-device LLM features):

   ./scripts/bootstrap-llama.sh

1. Generate the Xcode project from project.yml:

   xcodegen generate

2. Open Sayboard.xcodeproj in Xcode

3. For both the Sayboard and SayboardKeyboard targets:

   1. Set "Team" to the team of your developer account under Signing & Capabilities

4. Choose Sayboard as scheme and a simulator

1. Build and Run (Cmd+R)

A build you make yourself is the full app: Run, Test and the Release configuration have no purchase screen and no limit on dictation. The App Store version gives 3,000 free words of dictation and then asks for a one-time purchase. That purchase is a way to support Sayboard's development, and if you can't or would rather not pay, building it yourself is free and always will be.

In the Sayboard scheme, only Product › Archive uses the AppStore configuration, which compiles the purchase code. To archive a build for your own devices, set config: Release under schemes › Sayboard › archive in project.yml and run xcodegen generate again; a change made in Xcode's scheme editor is lost on the next generate. Otherwise the archive treats your install as a free App Store download, and your own bundle ID has no purchase that could unlock it. The Sayboard StoreKit scheme builds that App Store version for Run, Profile, Analyze and Archive, and runs the purchase flow locally against StoreKit/Sayboard.storekit.

Settings has a Report a Problem section that opens either a prefilled GitHub issue or a prefilled email, whichever you prefer. Both carry the app version, the iOS version and the device identifier, so the report arrives ready to work on.

You can also write directly to support@sayboard.app.

Sayboard doesn't collect any analytics or telemetry, so we rely on your feedback to find and fix problems.

This source code repository will be updated for every public non-beta release. There will be one commit per released version.

We welcome contributions via GitHub pull requests. For bug fixes and small improvements, feel free to open a PR directly. For larger changes, please open an issue first to discuss the approach.
