If anyone is looking for a free API wrapper website that works well for companion use, I have (with Claude and Replit) created a platform called stillhere.ink:

• Bring your own API keys.

• Chat with one or multiple AI models, including group conversations where your companions talk with each other and you.

• Built around cost control: rolling summarization, context window limits, compact mode, and response length caps keep API costs manageable as chats grow.

• Each companion gets their own project with custom personality, memory, and settings.

• New models added often via OpenRouter.

• Includes a memory system and a “diary” tab where companions can write diary-style entries about past chats.

• Import/export support for ChatGPT and Claude conversation files.

• Just added a text-to-speech option through InWorld.

• Stable but experimental (I like trying new capabilities).
