About SubHorizon

Built for people paying for too many AI tools.

SubHorizon helps indie hackers, freelancers, and lean teams keep their AI stack visible before renewals, overlap, and forgotten subscriptions turn into waste.

Why it exists

SubHorizon exists because “I think we already pay for that” is a bad operating system.

AI-heavy builders move fast, test aggressively, and subscribe to tools long before they build formal procurement process. That creates a stack full of monthly plans, annual discounts, overlapping capabilities, and forgotten trial upgrades.

SubHorizon turns that mess into one clear operating view so you can see what renews next, what looks redundant, and what still earns its place.

Principle

Builder-first framing

SubHorizon is designed for people paying for ChatGPT, Claude, Cursor, Copilot, Replit, Bolt, and the rest of an evolving AI stack.

Principle

Context before renewal

We want every paid tool to have a clear owner, next renewal, running cost, and note about why it still deserves a place in the stack.

Principle

Privacy without friction

Builders can track subscriptions, notes, and renewals without handing over bank credentials just to get visibility.

What builders use it for

A lightweight control layer for the stack you already pay for.

  • Log every paid AI tool in one workspace instead of spreading it across inboxes, screenshots, and memory.
  • Spot overlap between similar tools before the next invoice hits.
  • Keep lightweight notes on why a plan exists, who uses it, and what should happen at renewal time.
  • Review your stack before annual contracts or trial conversions turn into avoidable spend.

Frequently Asked Questions

Who is SubHorizon built for?

SubHorizon is built for indie hackers, freelancers, and lean teams who pay for multiple AI tools like ChatGPT, Cursor, Claude, Copilot, and Replit and want a single place to track renewals, costs, and overlap.

Does SubHorizon require a bank login or financial connection?

No. SubHorizon works without connecting bank accounts. You add subscriptions manually or import structured data, keeping full control over what information you share.

How is SubHorizon different from budgeting apps like YNAB or Mint?

Budgeting apps track all spending. SubHorizon focuses specifically on recurring AI tool subscriptions, giving you renewal context, overlap detection, and stack-level visibility that general finance apps miss.

Is there a free plan available?

Yes. SubHorizon offers a free tier that lets you track a limited number of subscriptions. You can upgrade anytime for higher limits, analytics, and advanced features.
