Everything the app does and why, written for the person running outreach. The [API reference](/api-reference/overview) documents the same platform for code; these pages document it for you. ## Accounts and browsers Connect in the app, wait out the initial sync, then work with it anywhere. One account, one isolated browser, one proxy. Lifecycle, checks, diagnostics. Lend an account to another workspace and take it back, or hand it over for good. ## Safety and pacing Per-action daily budgets, the warmup ramp, holds and how to release them. When recurring syncs run, what ignores the window, and how browsers sleep and wake. The signals behind the score, what each state means, and which ones self-heal. ## Finding and enriching Paste a search URL or build filters, on LinkedIn or Sales Navigator. Emails and phone numbers: what it returns, what it costs, and what an empty result means. Recurring collection that dedupes across runs and can feed a standing mass action. ## Conversations What the backfill imports, how often each surface refreshes, and why a reply may not be there yet. ## Workspace and billing What a workspace owns, how to invite people, and what each role can do. Sandbox, the forever free plan every workspace starts on, account pricing, and payment failures. ## When something breaks LinkedIn will not load, the account keeps asking for verification, the browser stops overnight. Start issues, sessions that die immediately, and login states that will not clear.
