TextGPT

TextGPT provides access to OpenAI’s ChatGPT and image models through text messages on any phone, enabling quick answers and image generation without installing an app. It targets users who want convenient AI access without a dedicated app, offering a text-based way to ask questions and receive outputs. The service emphasizes ease of access and a lightweight experience for everyday inquiries.

TextGPT runs on OpenAI's GPT-5.6 family and offers three tiers: Luna, Terra, and Sol. Users can switch tiers and adjust how long the assistant thinks before replying on their account page. Interactions are exchanges of text segments and AI processing, with credit costs tied to messaging and computing.

The tool supports questions, image generation through text, and editing based on supplied photos. Users can see their balance, change which model answers them on the account page, and save or delete conversations. Images are colorfully produced and priced by credit tiers, with different quality levels available.

Pricing shows two credit packs: $12 gets you 240,000 credits, and $24 gets you 480,000. Credits cover messaging segments and AI work, with defined per-segment costs and image pricing per quality level. The service uses three model tiers, has memory options for conversation storage, and provides web search capabilities via the AI models.
