Curated, not generated
Eric's Toolkit We retired the generic junk and kept the tools that solve real creator and operator workflows.
Paid Tool ROI Estimator Who it's for: Founders deciding if a custom tool is worth paying for.
Turns fuzzy “should we build this?” into numbers: payback period, annual ROI, and a scoped build request.
Outputs a pre-filled /build request with assumptions and bid guidance.
Open tool Invoice Generator Who it's for: Freelancers and creators sending clean invoices fast.
Real line-item invoice builder with tax, currency, and printable PDF output.
Works fully client-side and supports reusable defaults when signed in.
Open tool Sponsor CRM Who it's for: Creators tracking brand deals end-to-end.
Pipeline board from outreach to paid with follow-up dates and deal value tracking.
Local + cloud save support, stage transitions, export.
Open tool Newsletter Growth Tracker Who it's for: Newsletter operators who want honest growth metrics.
Tracks subscribers, open rates, click rates, growth velocity, and goal runway.
Computes trend metrics from your own entries, not vanity filler.
Open tool Competitor Tracker Who it's for: Small teams tracking market positioning without a giant BI stack.
Keeps pricing, features, strengths, and weaknesses in one structured table.
Data entry, edits, and JSON export are built in.
