No credits, no account needed.

What a private group is

Your own computers, or friends’ you invite, answering each other’s questions directly, encrypted end to end. No credits move, and woodls’ server never sees what you ask. A desktop at home can answer the laptop you carry, and a friend’s computer can answer yours while they sleep. Private groups has the short version.

On the computer that’s on most

It holds the group’s list.

Start one

woodls group create home
woodls group invite home

The invite shows two ways in, and waits up to 10 minutes for the other computer:

  • Six digits, for a computer on the same network: on it, woodls group join finds the group and asks for them. Open 10 minutes, 3 tries.
  • A short link, for a computer anywhere, to send by any messenger: on it, woodls group join woodls:…. Good once, within 24 hours (--hours makes it shorter), while woodls host runs on the computer that made it.
woodls group invite home --spoken
A code to read out on a call, such as “47 river lantern”
woodls group join 47 river lantern
Join with the words read to you
woodls group invite home --friend asha
Invite a friend’s computer, named for the friend
woodls group invite home --no-wait
Show the code and the link, and return

A spoken code is a number and two words, open 10 minutes, for one try. The two computers meet at woodls’ server, which sees the number and their addresses, never the words. A group’s name uses the letters a to z, digits, - and _, such as home or asha-home.

No invite

No account either.

Joining a friend’s group

Your friend sends a link, or reads you a code. Then:

  1. Install woodls with the one command for your computer.
  2. Run woodls group join with the link or the words. It needs nothing set up first.
  3. Ask: woodls ask --group home "…", or woodls code --group home.

To lend your computer to the group as well, woodls host --no-public --group home sets it up for private groups by itself, with a key of its own and no account; woodls init --groups-only does the same on its own.

If you’re in another group with the same name already, the new one goes by home-2 on this computer, or by the name you give with --as.

Free

Straight to its computers.

Asking your group

woodls ask --group home "…"
One question to the group
woodls chat --group home
A conversation
woodls code --group home
woodls code on the group’s model
woodls config set group home
Make it where your questions go

With a default group, --public sends one question to the public network instead. A computer in the group answers only while it runs woodls host --group home: see Lend your computer.

Online now

Direct or relayed.

Who’s in it

woodls group members home

Each computer: whose it is, which kind (a Mac, an NVIDIA computer), whether it’s online and what it serves, whether this computer reached it directly or through a relay, with the time it took, and when it was last seen. --here answers from what this computer knows, without asking them now. woodls group alone lists your groups.

woodls group remove home asha-pc
Remove a computer from a group you own
woodls group leave home
Leave a group this computer joined
woodls group delete home
Delete a group you own, for every computer in it

Invited by name

With hours you set.

A friend’s computer

Invited with --friend NAME, a computer is your friend’s, and is served only the models woodls has priced: gpt-oss 20B, Qwen3.6 35B and Qwen3 8B. Your own computers are served any model file. Each friend may use a share of your computers’ time: 15 minutes an hour, saving up to twice that, and 4 hours a day, unless you change it.

Short notes

Between your group’s computers.

Messages

woodls group message home \
  "Leaving the desktop on tonight"
woodls group messages home

A message goes straight to every computer of the group that answers, and says which have it. Only a computer running woodls host answers, so messages move while at least one of the group’s computers hosts; a host also passes them on every few minutes. A computer that was asleep gets them from a host the next time it runs woodls group messages or hosts. With no computer of the group hosting, a message stays on the computer that wrote it, and woodls group message says so. woodls group messages fetches new ones first, then shows the newest 20 (--last 50 for more) and marks them read.

  • Private: between the group’s computers only, encrypted, never through woodls’ server. Each is signed by the computer that wrote it, so nobody can change it or write in another’s name.
  • Limits: plain text, up to 500 characters; at most 5 a minute and 100 a day from a computer. Each group keeps its newest 200, for 30 days.
  • Where they show: a computer that lends to the group says each new one in its lines, without its words, and on a Mac shows it in Notification Center. woodls Studio shows them and sends them too.

A nudge

Its owner always decides.

Asking a computer to come online

woodls group nudge home studio

Asks the computer named studio to serve the group. Its owner always sees the ask. Only if they let asks in, with woodls group settings home --nudges on on that computer, does it come online sooner: a minute after their last touch instead of five, for half an hour, for the group alone. Never while they use it, on battery, when they paused it, or outside their hours. A computer that’s asleep or off can’t be woken. You can ask the same computer once every 10 minutes, and you’re told what happened.

Three days

Renewed while the owner lends.

How long the list lasts

The group’s list of members is signed by the computer that holds the group’s key, and lasts 3 days. woodls host renews it every hour while it runs there. If that computer is off for longer, the group waits for it. On the owner’s computer, this makes it last up to 7 days; a computer removed while the owner’s computer is off may then stay in that long:

woodls group settings home --list-lasts 7d

Encrypted traffic

And addresses.

What the relays see

Your computers find each other through a relay and, where they can, connect directly. When there’s no direct path, the encrypted traffic passes through a relay: woodls’ own in Mumbai, or a public one. A relay sees your computers’ IP addresses and when they’re online, never what they say. To find each other, lending computers publish their public key and relay address, never their IP address, to a public directory. --relays off keeps a group to computers on one network.

On Windows, woodls runs inside WSL2, behind Windows’ own network, so the six digits are often not heard: use the link or the spoken code.
