ChatGate (formerly ChatGPT AI) vs Writeseed

ChatGate at chatgpt.ai is a third-party AI gateway that routes chat, image, and video requests across ChatGPT, Gemini, Claude, and other major models from one web interface. You pick a model manually or leave routing on Auto, then generate without juggling separate provider accounts.

Unlike signing up directly with OpenAI or Google, ChatGate sells consolidated access through tiered subscriptions and adds a Discover feed that ranks newly launched AI apps by category. The chatgpt.ai domain redirects to chatgate.ai, so the product brands as ChatGate even though the listing URL predates the rename.

Builders, marketers, and researchers who want one bill for multiple frontier models fit here, especially if they also browse the Discover leaderboard for fresh tools. It is not the official OpenAI ChatGPT product at chat.openai.com.

Writeseed bundles writing, image generation, and post scheduling for LinkedIn and WordPress from one dashboard. You train a custom brand voice from your website or uploaded files, draft posts and articles in that tone, and push them to connected channels without juggling separate apps.

Most content suites pick one channel or one model. Writeseed gives you GPT-5, Gemini, Claude, Llama, and other top models in the same editor, plus an SEO and NLP panel while you write, a Chrome extension that follows you from Gmail to WordPress, and unlimited GPT Image 2 visuals for post graphics. That mix targets founders who want organic traffic and LinkedIn visibility from a single subscription.

The Growth plan runs $20 per month with unlimited use, 100+ templates, LinkedIn and WordPress integrations, and batch scheduling. Writeseed is operated by Postbrands GmbH in Germany and reports more than 10,000 professionals on the platform.
