TextGPT puts GPT-5.6 in your messages app. You text a number like you would text a friend, and an answer comes back as a normal text message — no app to install, no account to stay logged into, no data connection required.
Get startedEvery AI assistant today assumes you want to open an app, wait for it to load, and type into a chat window. That is a reasonable assumption at a desk and a bad one everywhere else — in a car, in a checkout line, on a phone with two bars of signal, or on a phone that cannot run the app at all.
SMS solves this by being the lowest common denominator. It works on every phone sold in the last thirty years, it works on 2G, and it is already the app your thumb reaches for. TextGPT is the same underlying model, delivered over the one channel that never fails.
Ask anything you would ask ChatGPT and get a written answer back, split across text messages when it runs long. The model has web search built in, so it can answer questions about current events rather than being frozen at its training cutoff.
You can also generate images without leaving the thread. Start a message with 🖌️ or 🖼️ and the rest is treated as the image prompt. The picture comes back as an MMS. Sending a photo works too — ask about it and you get an answer, ask for a change and you get an edited version.
Conversation memory is optional and off by default. Turn it on if you want the assistant to remember what you were talking about across messages; leave it off and nothing you send is stored.
TextGPT is prepaid. $12 is the minimum and buys 240,000 credits. A typical exchange runs about 2,000 credits once the text messages are counted, so that is around 120 conversations. Images cost 1,422, 4,242 or 13,722 credits depending on the quality you pick.
There is no monthly fee and nothing recurring unless you switch on auto-refill yourself. If you stop texting, you stop spending.
No. TextGPT works entirely through your phone’s built-in messaging app. There is nothing to download, no account to log into on your phone, and no browser required.
TextGPT is built on OpenAI’s GPT-5.6 models — the same family behind ChatGPT — accessed through OpenAI’s API. It is an independent service and is not affiliated with or endorsed by OpenAI.
There is no subscription. $12 buys 240,000 credits, which is around 120 back-and-forth exchanges, and $24 buys twice that. A good chunk of it is the messaging itself: 312 credits to receive your text and 327 for each 160-character segment sent back, with long answers running to several. Images cost 1,422, 4,242 or 13,722 credits depending on the quality you pick.
TextGPT currently supports US and Canadian mobile numbers. Support for other countries is not available yet.
$12 gets you 240,000 credits — around 120 questions. No app, no subscription, no commitment.
