Writingmate consolidates access to many frontier models behind a single subscription. The problem it targets is real and increasingly higher-priced: separate subscriptions to ChatGPT, Claude and Gemini, plus video and image tools, add up to well over a hundred dollars a month for someone who wants access to the best model for each task.
Beyond cost, there is a practical argument about switching. Different models genuinely have different strengths, and being able to move between them inside one interface, with the same files and web search available, means using the right model rather than defaulting to whichever subscription you happen to hold. It also provides continuity when one provider is degraded or rate-limited.
Aggregators depend on upstream API access, so model availability can lag official apps and provider-specific features may arrive late or not at all. For users who value breadth and cost control over having the newest feature on launch day, the trade is a good one.
