FYN vs Grok Bot
FYN turns your transactions and receipts into an ongoing money routine: budgets that stay current, changes worth checking, and a financial history your household can use.
Free to start. Bank sync requires Pro. See plans.
Grok Bot has real agent capabilities: persistent context, app use, and scheduled routines. See Grok Bot's overview. Its Finance connector also syncs account data through Plaid with read-only access.

Ask about balances, spending, subscriptions, and investments from linked accounts. Use its broader agent tools to teach workflows and schedule routines across your apps. A good fit when you want a general assistant you can shape around different jobs.

The work FYN is built for

Autopilot creates and maintains category budgets from your financial activity. Scheduled checks keep budgets current and watch for overspending between visits.
Explore AI finance tools“Let me know when a recurring charge goes up.”
FYN monitors for subscription increases, unusual spending, and possible duplicate charges, then surfaces alerts to review. Receipt reminders help you keep track of return deadlines.
Explore proactive alerts“Was that grocery run yours?”

Pair one coaching style with the focuses that matter to your household, using the same financial facts. These six focuses and five styles are included with Pro.
Track price changes in the things you buy and find the lowest prices in your own receipt history.
See what card interest costs you and compare payoff priorities, including the tradeoff between clearing smaller balances and paying the costliest card first.
Spot the habits that change your budget, from coffee runs to takeout nights. Compare how much and how often you spend with your own usual patterns.
See room for a chosen splurge in your budget and review recorded in-person spending from past trips.
See which staples you tend to rebuy, when they may be due, and where you have bought them for less.
Estimate what your usual month could cost in another city or state, using your spending mix and 2024 regional price data. Taxes and homeownership costs are not modeled.
Meal guides, detailed debt payoff plans, and investment recommendations remain on the roadmap.
Five coaching styles
A focus sets what FYN watches. A coaching style shapes the strategy and tone. Household owners choose one style and any combination of focuses in settings. Chat uses saved choices right away. Insights update on the next daily run.
Pro
FYN asks about possible duplicate charges and subscription price increases, with letters you review and send yourself. It remembers your response and tracks a disputed charge for a matching refund.
In development
Planned household budget checks and owner approvals would give connected agents guidance before spending, with a shared record of requests and decisions. This would be advisory: it would not block bank charges or move money.
Spend Guard is not publicly available.
Bring your own assistant
Connect a compatible assistant through MCP or the REST API to ask about your FYN transactions, budgets, subscriptions, and receipt history. Access is read-only, scoped to the account and permissions you authorize, and revocable. Receipt intelligence endpoints require Pro.
