Linger is an open-source personal agent that runs locally on your computer.
Open-Source · Local AI · Consumer Macs & PCs
Powered by Efficient AI model–harness co-design, it brings powerful local AI to everyday computers. It understands your context across files and apps, remembers what matters, and proactively gets things done.
Your data and memories stay private and local.
| Cloud chat assistant | Linger | |
|---|---|---|
| Where the model runs | A remote server | Your own GPU or Mac, on supported hardware |
| Where memory lives | The provider's account | On your device, in local mode |
| What it can reach | What you paste in | Files and apps you authorize |
| What you get back | An answer | A finished task, ready for review |
| Who can read the code | The vendor | Everyone. It is open source |
| Feature | What it does |
|---|---|
| Efficient AI model–harness co-design | Brings a full local agent to supported consumer Macs and PCs. |
| Efficient MoE inference | PolyStrata optimizes local inference so larger models can run with less GPU memory. |
| Privacy and data ownership | In local mode, personal data and memories stay on your device. Connected apps exchange data with their services. |
| Cross-app context | Understands work across authorized files and apps. |
| Wiki and memory | Remembers important information, preferences, and decisions across conversations, in wiki pages every agent can search. |
| Proactive Another Me | Watches your inbox, calendar and Slack, follows up and moves work forward, and messages you only when something needs you. Every "not now" teaches it. |
| Agent teams | Brings in the agents a job needs and writes one team.md that they all follow. |
For one person on one computer. Download the package for your platform from GitHub Releases. The app opens Linger, connects this computer and runs its agents. Quick Install on its setup screen sets up a Linger server on this computer too.
| Platform | Package |
|---|---|
| macOS, Apple silicon | Linger-<version>-arm64.dmg |
| Windows x64 | Linger-<version>-windows-x64-setup.exe, or -windows-x64-portable.zip to run without installing |
| Linux x64 | Linger-<version>-linux-x64.tar.gz (glibc 2.35 or newer) |
There is no package for Intel Macs; use Docker Compose there. Check each
download against SHA256SUMS.txt from the same release.
For a server that several computers share, or to build from source. You need Docker with Compose and at least 5 GiB of memory for its virtual machine.
git clone https://github.com/simplexai-labs/linger.git
cd linger
cp .env.example .env
docker compose up --build --detach --waitCreate the owner account. As written, it signs in as owner@linger.local with
the test password test1234; replace either one to use your own:
printf '%s\n' 'test1234' | docker compose exec -T teamhub \
teamhub-account create-owner --email owner@linger.local --password-stdinChange the test password in Settings › Security before other people can reach the server.
Open http://localhost:3000 and sign in. The app then shows the commands that connect your computer. See Install with Docker Compose to serve other computers on your network and to turn on voice.

Linger is built on these open-source projects:
- PolyStrata: Runs local models, keeping the experts a model uses most on your GPU.
- Strata: The inference engine PolyStrata is built on. It runs Qwen3.8-Flash-Next.
- BlockNote, Yjs and Hocuspocus: Power the documents that people and agents edit together.
- Hindsight: Where agent memory's fact extraction and search come from.
- Cua: Lets agents use the apps on your desktop.
- LiveKit: Carries the audio for voice and meetings.
- River: Runs TeamHub's background jobs.
- NOTICE: Lists every third-party component, what we adapted from it, and the license that applies.
Thank you to the open-source community for libraries this powerful and this simple: they let us focus on the product itself, and we hope our projects will in turn give everyone an easier-to-use knowledge base.
