Laya: Your AI Command Center
A cadence for professional orchestration.
Laya is an open-source, local-first AI notification command center that aggregates Slack, Gmail, GitHub, Jira, Notion, Outlook, and Calendar notifications — powered by local LLMs via Ollama and LM Studio, or cloud models like Claude and GPT with your own API keys. It intercepts events from your professional tools, performs autonomous research and action-staging using LLM-powered agents, and presents you with ready-to-approve Action Cards -- so the answer is ready before you open the notification.
Works with:
- Ollama and LM Studio (local LLMs)
- Claude models (Anthropic)
- GPT models (OpenAI)
- Gemini models (Google)
- Llama models and any OpenAI-compatible endpoint — via LiteLLM
Aggregates:
- Gmail
- Slack
- GitHub
- Bitbucket
- Jira
- Linear
- Notion
- Outlook (email and calendar)
- Google Calendar
How It Works
Your Tools (Jira, Slack, Gmail, Bitbucket, Calendar)
|
v
n8n (local Node.js) -- normalizes events
|
v
Laya Engine (Python) -- classifies, researches, stages
|
v
Laya UI (Tauri + Svelte) -- Action Cards you approve or dismiss
|
v
n8n -- executes approved actions (creates PRs, sends replies, etc.)
Key Features
- Multi-persona brain: Routes events to specialized AI personas (Engineer, Comms, Ops, Sales, HR, Finance) with domain-specific tools and prompts, with AI prioritization of every notification
- Card Workspaces: Agent workflows for complex tasks (bug fixes, code reviews) — interactive workspaces where you collaborate with a coding agent (Claude Code, Gemini CLI, Codex, Pi CLI, or Cursor Agent) through multiple approval steps
- Card Research: Launch on-demand deep research sessions on any card — a coding agent investigates with web search, semantic context, and sandboxed file access
- Agent inference backends: Run the classification/synthesis pipeline on an installed CLI agent's own quota instead of an API key — select a model of the form
agent/<id>/<model> (Claude Code, Codex, Gemini, or Pi) for any stage. Claude Code enforces JSON schemas natively; other agents use best-effort schema + retry
- Spaces: User-defined contexts grouping event sources with per-space model and API key configurations
- Context Association: Automatically links related cards across platforms using semantic similarity and LLM confirmation. Learns from your corrections to improve grouping accuracy over time
- Cross-platform memory: Entity resolution links "BUG-1234" in Jira to "PR-891" in Bitbucket to "the payment bug" in Slack
- Daily Briefing: Morning summary of overnight activity, pending cards, and today's calendar with context
- Analytics Dashboard: Track events processed, time saved, LLM costs (broken down by feature and pipeline step), throughput over time, and approval rates
- Budget Tracking: Monitor LLM costs by feature (Pulse, Omni, Chat, Coherence) with monthly caps and automatic pause when limits are reached. When running on agent inference backends, a separate window-based usage budget pauses ingestion as an agent's rolling quota nears its limit and auto-resumes when the window resets
- Chat sidebar: Ask Laya questions about your events, projects, and context — and create, edit, or delete filter/classification/processing rules directly from the conversation
- Hybrid search: Chat and Coherence retrieval combine local vector search (ChromaDB) with lexical BM25 ranking over SQLite FTS5 (
cards_fts/events_fts), merged via Reciprocal Rank Fusion, so both semantic and exact-keyword matches surface
- Coherence: Cross-platform entity search traces any person, ticket, or PR across all platforms using hybrid local search, with AI-generated narratives
- Egress: Execute outbound actions (emails, Slack messages, PR comments) directly from Laya with preview-before-send
- Omni: Rolling cross-platform summary that answers "where am I right now?" with four temporal layers (Attention, Recent, Period, Milestone) and progressive AI compression
- Bookmarks: Pin important cards for quick access regardless of date or status
- Classification learning: Laya extracts rules from your priority/persona corrections and improves classification automatically over time
- Context learning: Laya extracts natural-language context rules from your link/unlink corrections and improves context association over time. Learned and manual rules are viewable and editable in Settings, and large rule sets are LLM-consolidated automatically
- Processing rules: Automated, optionally AI-evaluated rules that act on incoming cards (tag, route, run an agent, send egress). Every firing is recorded in a searchable firing log with its outcome (success / error / skipped) and reason
- Audit & export: Inspect dead events, ingestion errors, and rule-filtered events in one place; retry or clear failures, and export filtered events or the audit log as JSON over any time window
- On-prem repositories: Self-hosted Bitbucket Server / Data Center and GitHub Enterprise are supported via a per-repo
host field (empty or the cloud domain ⇒ cloud)
- Dead event recovery: Failed events are tracked with error context and can be manually retried from the audit log
- Privacy-aware: Three-tier data classification with cloud/local processing options

Install
The fastest way to try Laya is a prebuilt release — no toolchains required.
Open the Releases page and download the installer for your platform:
| Platform |
Download |
| macOS |
.dmg (universal — Apple Silicon + Intel) |
| Windows |
.msi or .exe |
| Linux |
.deb or .AppImage |
Install and launch. You do not need Python, Node, or Rust installed to run a release build. On first run, Laya checks for a compatible Python (3.10–3.14; on Windows, an x64 build) and Node.js (20+) already on your machine and uses those if found; otherwise it provisions its own bundled runtimes. Either way, a local n8n instance is set up under ~/.laya/.
Add an API key (Anthropic, OpenAI, Google, …) or point Laya at a local Ollama / LM Studio endpoint, then connect your tools from Settings.
macOS: release builds are signed, so they open normally — just double-click to launch.
Want to build from source, hack on the engine, or contribute? Follow the Development setup below.
Development
Prerequisites
You need three runtimes installed. Here's how to get each one:
Python 3.10+
- macOS:
brew install [email protected] (or download from python.org)
- Ubuntu/Debian:
sudo apt install python3 python3-venv python3-pip
- Windows: Download from python.org (check "Add to PATH" during install)
Verify: python3 --version
Node.js 20+
- All platforms: Download from nodejs.org (LTS recommended), or use a version manager like nvm / fnm
- macOS:
brew install node
- Ubuntu/Debian:
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash - && sudo apt install -y nodejs
Verify: node --version && npm --version
Install via rustup:
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Verify: cargo --version
macOS:
xcode-select --install
Linux (Ubuntu/Debian):
Tauri v2 requires system libraries for GTK, WebKit, and app-indicator support:
sudo apt install -y libwebkit2gtk-4.1-dev libgtk-3-dev libayatana-appindicator3-dev librsvg2-dev patchelf
Troubleshooting
Linux: Tailwind CSS classes missing or styles not updating
The default Linux inotify file watcher limit (65,536) can be too low for this project -- Vite needs to watch the source files while the Rust target/ directory consumes most of the quota, causing Tailwind CSS to silently fail to generate utility classes. Increase the limit:
# Immediate (resets on reboot)
echo 524288 | sudo tee /proc/sys/fs/inotify/max_user_watches
# Permanent
echo 'fs.inotify.max_user_watches=524288' | sudo tee -a /etc/sysctl.conf
sudo sysctl -p
Linux AppImage: blank white window, WebKitWebProcess aborts with EGL_BAD_PARAMETER
On distros whose Mesa is built against libwayland 1.23 or newer (Arch/CachyOS, Fedora 44+, Ubuntu 25.04+ in some configurations), the AppImage may open a blank window and print:
Could not create default EGL display: EGL_BAD_PARAMETER. Aborting...
The AppImage bundles an old libwayland-client.so.0 (from the Ubuntu 22.04 build host) and forces it onto every process via LD_LIBRARY_PATH, while EGL/Mesa come from your system. Newer Mesa needs Wayland symbols the bundled copy lacks, so its EGL driver fails to load and WebKit aborts. WEBKIT_DISABLE_DMABUF_RENDERER, GDK_BACKEND=x11 and similar variables do not help because the failure happens before any renderer is chosen.
Workaround: extract the AppImage, delete the bundled Wayland libraries so the system copies are used, and run the extracted app:
./Laya_*_amd64.AppImage --appimage-extract
mv squashfs-root ~/.local/share/laya-app # or anywhere permanent
rm ~/.local/share/laya-app/usr/lib/libwayland-*.so.*
~/.local/share/laya-app/AppRun
The .deb and .rpm packages use your system WebKitGTK and are not affected, so prefer them where they install cleanly. This is caused by the AppImage bundler Laya uses (Tauri pins an old linuxdeploy whose exclude list predates the upstream libwayland-client exclusion); see tauri-apps/tauri#15665 and tauri-apps/tauri#15976, tracked for Laya in #17.
Linux setup: "Setting up automation" fails with EALLOWREMOTE (npm 12+)
If ~/.laya/logs/n8n-install.log ends with:
npm error code EALLOWREMOTE
npm error Fetching packages of type "remote" have been disabled
npm error Refusing to fetch "xlsx@https://cdn.sheetjs.com/xlsx-0.20.2/xlsx-0.20.2.tgz"
your npm is version 12 or newer, which defaults allow-remote to none. n8n depends on n8n-nodes-base, which pins xlsx to a tarball hosted outside the npm registry, so npm refuses to install it. This happens when Laya finds a system Node 22+ whose npm was upgraded separately (for example Arch's npm package). Laya's managed Node download ships npm 10 and is unaffected.
Laya passes --allow-remote=all on its n8n install starting with the release after v1.9.1. On v1.9.1 or earlier, install n8n by hand with a project-local .npmrc so your global npm settings stay untouched, then click Retry in the setup screen:
mkdir -p ~/.laya/n8n_module
printf 'allow-remote=all\n' > ~/.laya/n8n_module/.npmrc
npm install --prefix ~/.laya/n8n_module [email protected]
allow-remote=root is not enough because xlsx is a transitive dependency. Tracked in #18.
Windows (incl. Windows on ARM): setup fails with "Wheels are required for aiohttp" / tiktoken / chromadb
If the "Installing Python packages" step fails and %USERPROFILE%\.laya\logs\pip-install.log contains a line like:
hint: Wheels are required for `aiohttp` because building from source is disabled for all packages (i.e., with `--no-build`)
Laya picked up a Python from your PATH that it can't install its dependencies into. Laya installs only prebuilt wheels (it never compiles packages), and two kinds of interpreter have no wheels for some of its dependencies:
- Python newer than 3.14 (e.g. 3.15):
aiohttp, torch and others haven't published wheels for it yet. This affects every platform.
- Native ARM64 Python on Windows (
win-arm64), any version: chromadb, tiktoken, litellm (via fastuuid), grpcio and torch publish no Windows-on-ARM wheels. The Windows release of Laya is an x64 app, which Windows on ARM runs under emulation, so it works with an x64 Python.
Releases after v1.9.2 skip these interpreters automatically. They download Laya's own x64 Python 3.12 instead and rebuild a venv that was created with the wrong interpreter. On v1.9.2 or earlier, quit Laya and point it at a compatible Python yourself, using either option below. Then relaunch Laya. Setup rebuilds the venv, which takes a few minutes.
Option A (recommended): pre-install Laya's managed Python. Laya prefers %USERPROFILE%\.laya\python over anything on PATH, so this works regardless of which other Pythons you have. In PowerShell:
$laya = "$env:USERPROFILE\.laya"
Remove-Item -Recurse -Force "$laya\venv", "$laya\.deps_hash", "$laya\python" -ErrorAction SilentlyContinue
New-Item -ItemType Directory -Force $laya | Out-Null
$tag = "20260510"; $ver = "3.12.13"
$url = "https://github.com/astral-sh/python-build-standalone/releases/download/$tag/cpython-$ver+$tag-x86_64-pc-windows-msvc-install_only.tar.gz"
Invoke-WebRequest $url -OutFile "$env:TEMP\laya-python.tar.gz"
tar -xzf "$env:TEMP\laya-python.tar.gz" -C $laya # creates .laya\python
Set-Content "$laya\python\.version" $ver -NoNewline
Remove-Item "$env:TEMP\laya-python.tar.gz"
Option B: install an x64 Python 3.12 or 3.13 and put it first on PATH. Download the "Windows installer (64-bit)", not the ARM64 one, from python.org and tick "Add python.exe to PATH". Then make sure python --version in a new terminal reports that version. Run python -c "import sysconfig; print(sysconfig.get_platform())" to confirm it prints win-amd64. Finally, delete %USERPROFILE%\.laya\venv and %USERPROFILE%\.laya\.deps_hash.
pip install laya is not a way to install this app. The laya package on PyPI is an unrelated project that requires torch. Use the installers on the Releases page. Tracked in #14.
Linux: Tauri build fails with unable to find library -lssl / -lcrypto
The Rust shell is rustls-only and should not need system OpenSSL, which is why libssl-dev is not in the apt list above. If the linker asks for -lssl/-lcrypto, a dependency has pulled in native-tls (→ openssl-sys) again -- usually a reqwest declared without default-features = false. Find the culprit with:
cd ui/src-tauri && cargo tree -i openssl-sys
and fix the offending dependency's features. As a stop-gap, sudo apt install libssl-dev lets the build link as-is.
Setup
scripts/setup-dev.sh
This script does the following:
- Checks that
python3, node, npm, and cargo are available
- Creates a Python virtual environment at
engine/.venv/ and installs dependencies from engine/requirements.txt
- Installs npm packages for the UI (
ui/node_modules/)
- Installs n8n as a local npm package into
~/.laya/n8n_module/
- Creates data directories at
~/.laya/data/ and ~/.laya/logs/
Running Locally
scripts/dev.sh
This starts two processes:
- Python engine --
python -m laya.main (with hot reload) at http://127.0.0.1:8420
- Tauri dev server --
npx @tauri-apps/cli dev which starts Vite at http://localhost:5173 and opens the Tauri window
n8n is managed automatically by the Tauri app -- it starts on launch (port 45678) and stops on quit.
Note: If the engine fails with "Address already in use", a stale engine process may be holding port 8420. The engine will attempt to kill it automatically on startup.
Configuration
On first launch, the engine creates config files in ~/.laya/:
| File |
Purpose |
settings.json |
Models, agent paths, privacy settings, pipeline params |
team.json |
Team member context |
rules.json |
Event filtering rules |
repos.json |
Git repository paths and metadata |
API keys (Anthropic, OpenAI, Google, etc.) are stored securely in your OS keychain and can be configured through the Settings UI.
The engine logs at INFO by default. Change verbosity from Settings → Data → Engine Log Level (DEBUG / INFO / WARNING / ERROR) — this maps to the logging.level key in settings.json and applies immediately, no restart. Set it to WARNING to record only warnings and errors and keep logs small. For a single run you can override it with the LAYA_LOG_LEVEL environment variable, which takes precedence over the setting (and also sets uvicorn's request-log level).
Custom Prompts
Laya's AI pipeline uses system prompts at every stage (routing, staging, summarization, chat, etc.). All prompts ship with sensible defaults, but you can override any of them by placing files in ~/.laya/prompts/:
mkdir -p ~/.laya/prompts
# Override the router prompt (controls event classification)
vim ~/.laya/prompts/router.md
# Override a worker persona
vim ~/.laya/prompts/engineer.md
# Reload without restarting
curl -X POST http://127.0.0.1:8420/prompts/reload
Available prompt files: router.md, stager.md, omni.md, group_summary_initial.md, group_summary_rolling.md, briefing.md, summarizer.md, summarizer_status_change.md, engineer.md, comms.md, sales.md, hr.md, ops.md, finance.md, chat.md, chat_title.md, chat_polish.md, learner.md, context_learner.md, trace_narrative.md, trace_summary.md, trace_filter.md.
Custom prompts fully replace the built-in default for that stage. If a file is deleted, the hardcoded default is used automatically. The engine never creates or modifies files in this directory. Use GET /prompts to check which prompts are currently overridden.
Data Storage
| Store |
Location |
Purpose |
| SQLite |
~/.laya/data/laya.db |
Events, cards, workspaces, spaces, traces, egress, chat |
| ChromaDB |
~/.laya/data/chroma/ |
Vector embeddings for semantic search |
| n8n |
~/.laya/n8n/ |
Workflow data, credentials (encrypted) |
| Logs |
~/.laya/logs/ |
engine.log — rotating engine logs (10 MB × 5 files), verbosity set by the log level above. Also engine-stdout.log and n8n.log — captured process output, likewise rotated (10 MB × 3 files). |
Building for Distribution
Laya bundles the Python engine source into the Tauri app. On first launch, the app creates a Python virtual environment at ~/.laya/venv/ and installs dependencies automatically -- no Python installation is required on the end user's machine beyond what the app manages.
Build Command
scripts/build.sh
This does two things:
- Bundles engine source -- copies
engine/laya/, the requirements files and their lock files, and n8n/workflows/ into ui/src-tauri/resources/engine/
- Builds the Tauri app -- compiles the Rust shell, bundles the SvelteKit frontend, and packages everything into a platform-native installer
Build Options
scripts/build.sh # Build for current platform
scripts/build.sh --target x86_64-apple-darwin # Cross-compile for Intel Mac
scripts/build.sh --universal # Universal binary (arm64 + x86_64)
scripts/build.sh --sign "Developer ID App: ..." # macOS code signing
scripts/build.sh --skip-engine # Skip engine bundling (reuse previous)
