LangBot Agent
More than chat. Help with the work.
Answer questions, work with files, and welcome new members. Let your bot handle everyday tasks.
Get work done in a sandbox
A sandbox gives your Agent an isolated workspace to run code and work with files. You choose which tools it can use.
Set up once, use across bots
Use the same Agent across multiple bots and chats without repeating the setup.
Team collaboration
You don’t have to do it all alone
Invite teammates to your workspace, share bot management and daily upkeep, and put your data to work together.
Explore team collaborationOne workspace, shared responsibility
Everyone joins with their own account to manage bots, knowledge bases, and extensions together. No shared admin password needed.
The right access for each role
Assign roles to match each person’s work, whether they configure bots, handle daily operations, or just need to view.
Take your data into the discussion
Export message records, model call logs, and user feedback as CSV to build reports and review usage with your team.
