Agents for business teams
Solid

Choose Muse for a personal agent. Choose Solid when several people need agents to work under the same business rules.
What Solid adds for a business team
A recurring job should keep its instructions and access when a different colleague takes over.
Keep the team's instructions
Agents remember approved instructions and corrections from across your team, so each colleague can build on what the agents have already learned.
Give agents separate accounts
Equip agents with separate Google and Apple accounts, with access limited to the work your team approves.
Use the software the job needs
Within your access rules, agents can set up computers and phones to use the same software as your team.
Set rules for routine purchases
Give agents a budget for services and tools. Your approval policy determines which purchases they can make and which need your review.

Get started with SolidQuestions about using Solid for your team
What should I give Solid for the first job?
Give Solid a job you can check, such as preparing a weekly sales report. Share the data, instructions, and access the agents may use, then set a budget and any approval requirements. The agents can work out the setup and explain what else they need.
Will Solid remember instructions from our team?
Solid's agents retain approved instructions, decisions, corrections, and feedback from across your team. Later jobs can use that knowledge within the access rules you set.
Can Solid's agents work without my personal accounts?
Solid can give individual agents separate, approved Google and Apple accounts. Your team controls what those accounts can access, subject to each provider's policies.
Can Solid's agents use our existing business tools?
Solid's agents can use your existing software through APIs, browsers, desktops, and phones. If a connector is missing, they can build a connection or use the tool's interface, within your approved access and the service's rules.
Can Solid run in our own environment?
Solid can run in Solid Cloud, a customer-controlled virtual private cloud (VPC), or an on-premises environment. Availability and setup need to be scoped for your team's workflow.
How does Solid control spending?
Solid's agents spend within your budgets and approval rules. AI usage, computers, and approved purchases draw from one account balance funded by your subscription. You can ask the agents what a job costs and which resources it uses.
What happens when Solid's agents get stuck?
Solid's agents can inspect a failed job, change tools or repair the setup, and rerun the work to check the fix within your access and approval rules. They retain useful lessons for later jobs. You can bring in a real person when you need help.
