List every AI tool that bills you.
Add the tools you actively pay for, the renewal date, the plan, the owner, and the reason each tool exists in your workflow. The first useful view is the current stack, not a perfect accounting archive.
Built for the subscription stack that did not exist two years ago.
The expensive part of AI tooling is rarely one product. It is the mix of assistants, code editors, app builders, research tools, image tools, APIs, trials, and annual renewals that all bill separately. SubHorizon turns that scattered stack into a reviewable inventory.
See duplicate capability before you pay twice.
ChatGPT, Claude, Gemini, Cursor, Copilot, Windsurf, Bolt, Lovable, and v0 can overlap in expensive ways. Grouping tools by job makes cancellation and downgrade decisions easier before charges land.
Turn autopay into a review workflow.
Monthly and annual renewals are most manageable when they appear on one timeline. SubHorizon keeps the next charge visible so each subscription gets a keep, downgrade, or cancel decision.
