​
Chat modes at a glance

Group and DM conversations keep their own history, so context stays scoped to the current conversation.

​
Group basics

  • Group owners can create up to 15 groups.
  • New groups start with a general text channel.
  • Invite links are generated per group and can be refreshed.
  • Group roles are intentionally simple: owner and member.

​
Ownership rules

  • Only the owner can rename/update/delete the group.
  • Only the owner can add/remove members directly.
  • Only the owner can add/remove verbs in the group.
  • Owners cannot leave their own group without transferring ownership first.

​
Members and verbs

​
Adding members

  • Members added through invite codes join with member permissions.
  • Inviting/joining triggers system events visible to the group.

​
Adding verbs

You can add:
  • Your own verbs.
  • Public verbs from other users.
You cannot add:
  • Private verbs you do not own.

​
DMs

You can start DMs with:
  • Another user.
  • A verb.
For verb DMs:
  • Public verbs are available to everyone.
  • Private verbs are only available to the owner.

​
Message flow and limits

​
History pagination

When loading messages:
  • Default fetch size: 50
  • Max fetch size: 200

​
Message requirements

A message must include at least one of:
  • Text content
  • A valid URL-style content body
  • At least one attachment

​
Anti-spam protection

Messages can be blocked when they look abusive, including:
  • Mention flood
  • Excessive zero-width character usage
If users report random send failures, check for copied invisible characters and heavy mention payloads first.

​
Upload limits

  • General chat attachments: up to 30MB per uploaded file
  • Document text extraction: up to 20MB per document
  • Up to 4 attachments are analyzed for one model turn
  • Supported uploads include images, video, audio, PDF, Word documents, and common text/code formats
For model understanding, Verba caps extracted text to 7000 characters per attachment and 16000 characters total. Video understanding can sample up to four frames per attachment and transcribe available audio. Very large or unsupported media may still be stored as a normal file without full AI analysis.
Legacy image-only upload routes still use a 5MB image limit. The paperclip file uploader in current app chat uses the broader 30MB attachment path.

​
Reactions, edits, and deletes

  • Users can edit/delete their own messages.
  • Group owners (or users with manage message permissions) can moderate group messages.
  • Reactions are supported for both group and DM messages.

​
Real-time behavior (WebSocket)

Verba live chat uses WebSocket channels for:
  • New message events
  • Message edits/deletes
  • Typing indicators
  • Group/DM subscription updates
This is why messages appear instantly across open sessions when everything is healthy.

​
Why a verb did not reply

Common causes:
  • The verb was not configured to auto-respond in that context.
  • The message was blocked by anti-spam rules.
  • The sender does not have permission to post in the group.
  • The verb or channel settings limit responses.
