A freelance writer or small content agency hits the '10 free credits per day' wall not once, but every single working day across every client project. They're not evaluating — they're trying to get work done. The individual tool's free tier was designed for a single curious user, not for someone running four client accounts who needs consistent daily throughput.

The reason this remains broken is that AI writing tool vendors price and structure plans around individual seats or individual companies. A freelancer working across five clients has no clean way to justify a $49/month per-tool subscription for each, and no tool offers a model where their clients could contribute to a shared pool. The buyer (the agency) and the user (the freelancer) are the same person, but the vendor's pricing model was built for someone else — a marketing team at a single company.

Users explicitly ask for this: 'it would be better to receive at least 100 credits every day' and 'the free version only gives you 1000 credits per month' — not complaints about pricing per se, but about the mismatch between what the tool allows and what a real workday requires.

Without a shared credit pool, small agencies either force every team member to maintain their own free account (against terms of service, fragile, and manually tracked), buy full seats for occasional users (wasteful), or just don't use AI writing tools at billing-sensitive projects at all. This is a recurring cost every month, not a one-time frustration.

What to build

Build an agency-tier credit aggregator that purchases credits in bulk from AI writing APIs (where available) or manages seat-sharing logic across tools, then distributes them to subaccounts per client project with monthly usage reporting the agency can show clients as a line item.

Where to start

Start with agencies already using a single dominant tool (whichever has the most accessible API or reseller program) and solve pooling for just that one tool before expanding — pitch it as 'client billing for AI writing costs' rather than 'credit management.'

The hard part

Most AI writing tools don't expose public APIs with granular per-call credit billing, so building true credit aggregation may require negotiating reseller or partner agreements before the product works at all — making the first version dependent on a business development hurdle, not just engineering.

How it makes money

Margin on bulk credit resale (buy at volume discount, sell at slight markup) plus $29/month per agency for the reporting and subaccount management layer.
