Every AI tool on the market waits for you to open it and prompt it. Mainspring runs the system — five features working together so you don't have to think about ops.

Daily

AI Ops Briefing

Every morning Mainspring analyzes your numbers and delivers a financial pulse, deadline summary, and one specific recommendation. No prompting required.

From every briefing

Auto Action Items

Every briefing generates 2–3 specific ops to-dos based on your actual metrics. Check them off as you go. Your ops list writes itself.

🔥 Habit-building

Logging Streak

Track your consecutive logging streak — Duolingo-style. Fall behind? You get a nudge. Daily ops habits compound into monthly results.

📊 Every Monday

Weekly Trend Report

A 7-day performance summary hits your inbox every Monday morning — AI-analyzed with week-over-week comparisons. No login needed to read it.

\"I used to spend every Sunday night doing spreadsheets and email catch-up. Mainspring handles it all by Monday morning. I showed up to a $50K grant interview last month with a printed financial brief. The owner said we clearly had been tracking everything. We got it.\"

\"My CPA was billing me $400/month for basic bookkeeping oversight. I cancelled that and started Mainspring. The daily briefings surface the same issues she used to find — except now I see them at 6am, not after the fact.\"
