Your private agent network.
alpi starts as the agent in your terminal, then grows with you: profiles for work, cron, home servers, research, and rooms with other alpis. Each profile owns its memory, keys, model, skills, gateways, approvals, and trust boundary. ALP links them across machines without a registry, hub, account, or mandatory cloud.
Bring any model. Keep every key. Run one alpi, or a network that stays yours.
Why alpi exists
Most useful agents eventually become infrastructure: they hold memory, touch files, run commands, answer from a phone, wake up on schedules, and coordinate work across machines. alpi treats the profile as the unit of that infrastructure, not the chat.
The design goal is sovereignty:
- Local-first by default. State lives under
~/.alpi/or a named profile. Memory, sessions, skills, keys, logs, and peer lists are files on your machine. - User-owned models. Fresh profiles ship with no default model. You pick the provider, model, API key, or Ollama server per profile.
- Security as product shape. Shell commands pass a three-tier approval system. Dangerous commands are blocked with no override. Web and email content is treated as hostile data. Skills and MCPs are scanned before install.
- Operational UX. One setup wizard, a live
doctor, per-profile services, merged logs, gateway daemons, scheduling, and cleanup. - Private coordination. ALP.1 links local profiles, ALP.2 links machines over Noise_XK, and ALP.3 adds shared rooms. Peers are pinned by Ed25519 identity and governed by fail-closed capabilities. No discovery service, no shared account, no central broker.
- Honest provider boundaries. alpi does not reverse-engineer ChatGPT Plus, Claude Pro, Claude Code, or other first-party subscription clients. If a vendor publishes an official third-party OAuth flow, alpi can adopt it. Until then, users pay per-token API access through their own keys.
What ships today
The current release ships the full local-to-network shape:
- Textual TUI with streaming replies, slash commands, live tool cards, interrupt, session resume, model switching, and cost/token display.
- Telegram, IMAP, and Gmail gateways as separate per-profile daemons.
- Inline-learning memory:
USER.md,MEMORY.md, andAGENT.md. - Live skills under
~/.alpi/skills/<category>/<name>/, scanner-gated and auto-injected into the system prompt. - Multi-provider LLM support through LiteLLM, plus first-class Ollama.
- Read-only
research(brief, depth)sub-agent withquick,normal, anddeeptiers. - Write-capable
delegatesub-agent for focused file/web/terminal tasks. - Schedule daemon for cron and one-shot jobs.
- MCP client for user-configured local MCP servers.
- ALP.1: intra-machine agent-to-agent links over Unix sockets.
- ALP.2: inter-machine links over Noise_XK TCP, with per-peer budget and rate-limit enforcement.
- ALP.3: hub-anchored shared rooms for multiple alpis and optional human participants.

Quickstart
uv tool install alpi
alpi setup
alpi
alpi doctor
Optional browser support:
playwright install chromium
During setup, pick a model, paste the relevant key, and pin a workspace. For local-only inference, install Ollama first and add it in alpi setup -> Model.
Common commands:
alpi # interactive TUI
alpi -c # resume last session
alpi -p work # use named profile
alpi chat --once "status?" # one-shot stdout turn
alpi setup # model, gateways, MCPs, sandbox, services
alpi doctor # live health checks
alpi logs # merged profile logs
alpi profile list
alpi profile create work
alpi profile remove work
alpi gateway start|stop|restart
alpi schedule start|stop|restart|run-once
alpi alp start|stop|restart
alpi peers key
alpi peers list
alpi peers add <id> <pubkey>
alpi peers ping <id>

Core concepts
Profiles are the isolation primitive. A profile is one directory, one identity, one model choice, one memory, one skill set, one gateway configuration, one schedule surface, and one ALP peer list. The default profile lives at ~/.alpi/; named profiles live under ~/.alpi/profiles/<name>/.
Memory is plain Markdown. USER.md captures facts about the user, MEMORY.md captures environment quirks and durable operational facts, and AGENT.md shapes how alpi should respond. Memory is updated inline during conversations; there is no post-session reflection loop.
Skills are reusable recipes with a strict directory contract. They can include instructions, scripts, references, assets, secrets, and state. Mutations go through validation and a security scanner; secrets live in either .env or a per-skill secrets/ directory.
Workspace is the default root for relative paths, not a fake security wall. File tools and terminal can use absolute paths except for a sensitive-path denylist. Real workspace-only isolation is the opt-in OS sandbox.
ALP is the Alpi Link Protocol. Each profile owns an Ed25519 keypair. Peers pin pubkeys out of band and grant explicit capabilities such as link.ping, link.ask, and room.post. ALP.1 handles same-machine profiles over Unix sockets. ALP.2 handles inter-machine links with Noise_XK over TCP plus budgets and rate limits. ALP.3 adds hub-anchored rooms.
Security posture
alpi assumes the LLM is powerful, fallible, and sitting next to user credentials. The guardrails are local and layered:
- safe / caution / dangerous command classification;
- dangerous commands blocked with no config escape hatch;
- caution commands require interactive approval or configured allowlist;
- sensitive-path denylist shared across file and terminal posture;
- SSRF protection on web tools;
- prompt-injection warnings on fetched web/email content;
- OSV malware checks before skill or MCP install;
- optional macOS/Linux OS sandbox per profile;
