For SMBs, the practical lesson is clear: govern memory, connectors, credits and publishing rights before automation scales. ## What changed in Perplexity Computer? Perplexity's 14 July 2026 Computer update adds Brain, a memory layer that Perplexity says builds a private context graph across sessions, connectors, files and past decisions. The practical point is not to use memory everywhere; it is to make retained context inspectable, source-linked and removable. > RxAI insight: Treat agent memory like an operating record, not a convenience feature. Every remembered preference should have a source, an owner, a review path and a deletion path. ## Why does agent memory need governance? Perplexity reported internal testing where Brain lifted answer correctness by 25%, recall by 16% and reduced cost by 13% on tasks with prior context. These are Perplexity's own test results, not a guarantee for every workflow, but they show why repeatable, source-backed work is the best place to test memory. ## Where should SMBs test memory first? Start with one low-risk recurring workflow: - Weekly competitor monitoring. - Monthly social performance summaries. - Standard client briefing packs. - Finance-watch summaries. - Internal research digests. Avoid first pilots that combine sensitive customer data, public publishing, external actions and unclear review responsibility. ## How do model switching and credits change the operating model? Perplexity's update adds faster Computer model options, Claude Fable 5 as an orchestrator option and mid-task orchestrator switching. Its Help Center says Computer uses credits for multi-step work, with 100 credits equal to 1 U.S. dollar at the time checked, and tasks can pause or resume when credits or spending caps are hit. SMBs should set a budget rule before scaling: which workflows can use stronger models, when human approval is needed and which reports track usage by model. ## What should you check before connecting business tools? Remote connectors can connect Perplexity to external tools and data sources through MCP. Perplexity says remote MCP server URLs require HTTPS and can use OAuth, API key or no authentication. It also warns that custom connectors introduce risk. Review these before rollout: - Connector owner and approval history. - Data exposed by the connector. - Read versus write permissions. - Authentication method and HTTPS status. - Admin controls for shared connectors. - Memory review and deletion process. ## What about AI-generated websites and public output? Perplexity says Computer can publish websites to pplx.app or through Vercel to a custom domain, with visibility controls for private, specific people, organisation-only or public web access. That can help with landing pages and internal dashboards, but public output needs brand, legal and analytics review before launch. ## What should an SMB do this month? Choose one recurring workflow, define its sources and reviewer, run it for two to four cycles, then measure time saved, error rate and credit cost.

Brain is Perplexity Computer's memory layer. Perplexity says it builds a private context graph across sessions, connectors, files and past decisions so future tasks can reuse relevant context. ### Should SMBs turn on agent memory everywhere? No. The safer starting point is one low-risk recurring workflow with known sources, a fixed output format, a human reviewer and a clear way to inspect or delete retained memory. ### How should a business govern AI agent credits? Set a budget for recurring tasks, decide which workflows can use stronger models, review usage by model where available and define a stop point before credit spend becomes open-ended. ### What should be reviewed before adding custom connectors? Review the connector owner, data exposure, authentication method, HTTPS requirement, read/write permissions and admin controls before any agent can use the connector in a business workflow.
