A Chromium desktop browser with a built-in agent that signs in and completes real work across your logged-in sites.

Agentic Browsing: The agent operates your logged-in websites directly - clicking, typing and navigating - so tasks that need no public API still get done.
Local Memory: Browsing history is distilled into on-device memory files so the agent already knows which tools and accounts a recurring task involves.
Agent Password Manager: Credentials are autofilled into pages through hardware-backed encryption and Secure Enclave storage, never handed to the model.
Human Approval Gates: Sensitive steps such as payments, posts and outbound messages pause for your confirmation before the agent proceeds.
Access Audit Log: Every credential use and scoped permission grant is recorded so you can see exactly what the agent touched and when.
Routines: Scheduled recurring tasks, such as a 9am daily briefing, run on their own and drop results back into the browser.
Bring Your Own Model: Connect an existing ChatGPT or Claude subscription or your own API key rather than paying twice for inference.
Sandboxed Execution: Filesystem and network access are isolated with guardrails so agent runs cannot reach beyond what the task needs.

Operations Backfill: Push the same record update through several internal dashboards that have no shared API.
Recruiting Prep: Reopen a candidate profile viewed yesterday and assemble interview notes from the sites already visited.
Inbox and Comment Triage: Draft replies, follow-ups and comment responses across email and social accounts under review.
Daily Briefing: Schedule a routine that gathers overnight metrics and trending topics into one morning summary.
Sales Research: Work through prospect sites and CRM screens to collect context before an outreach sequence.
Spreadsheet and Document Work: Have the agent edit local files and web spreadsheets as part of a longer task.

Product adoption agent that reads each user's in-product behavior and writes timely, personalized guidance to move them to the next feature or habit.

Adoption Goal Campaigns: You define the product behavior you want users to adopt and Lumi builds the campaign around it, qualifying an audience and giving a clear reason for every match.
Behavior-Grounded Personalization: Lumi reads each user's actual session history and writes a message specific to what they did, rather than merging variables into a shared template.
Actionable Plan Delivery: Every nudge hands the user's own stalled task back to them as a short runnable plan with a single call to action, instead of a generic feature announcement.
Brief-Based Guardrails: You set goal, context, tone and guardrails once - quiet hours, one nudge per N days, skip conditions - and Lumi writes every message inside those limits.
Dual Data Sources: Lumi combines your product database, which shows what each customer is entitled to do, with your analytics, which shows what they actually do, to pick the next best action.
Behavioral Outcome Measurement: Success is tracked against product KPIs such as feature adopters and usage quality rather than email opens or clicks, showing who adopted and who stalled.
PostHog and Database Integrations: Native PostHog and database integrations are available from the free tier upward, with additional data integrations on higher plans.
Ship-Speed Follow-Up: As the product changes, Lumi continuously finds the users who have fallen behind on new functionality and gives each the guidance to catch up.

Feature Launch Adoption: After shipping a new feature, automatically identifying which existing users it applies to and explaining it to each of them in their own context.
PLG Activation: Moving self-serve signups past their first stalled workflow so trials convert without a human onboarding call.
Scaled Customer Education: Giving every account the founder-level attention that was only feasible for the first ten customers, across thousands of users.
Churn Risk Intervention: Catching users who repeatedly retry, abandon or work around a task and sending them a corrective plan before frustration turns into churn.
Habit Formation: Nudging power users toward higher-leverage workflows such as planning before execution, and measuring whether the habit actually took.
Adoption Reporting: Showing product and growth teams which KPIs moved after guidance went out, tied to specific campaigns.
