ChatBuddy: Every AI, One App

ChatBuddy puts 23 AI models from 9 providers behind one balance. Pick the model for each message, see what a reply costs before you send it, and change your mind halfway through a conversation. There is no subscription, no Pro tier, and nothing sitting behind an upgrade screen.

EVERY MODEL, ONE APP
Claude, GPT, Gemini, Grok, DeepSeek, Kimi, Qwen, Mistral and Venice models sit in a single picker, sorted cheapest first, each showing its price per reply. Ask a quick question on a cheap, fast model. When the answer matters, hand the same thread to a stronger one — the conversation carries over and you do not start again.

PAY FOR WHAT YOU SEND
Replies are priced per message, from 0.02 credits. The picker shows every model's rate before you choose it, and each reply is stamped with the model that wrote it and what it cost. No meter runs in the background. If a provider fails, you are not charged.

NO SUBSCRIPTION, EVER
Credits you buy never expire. Packs are $3.99 for 100, $8.99 for 250, $15.99 for 500 and $29.99 for 1,000. Your first pack of 250 or more includes 50 bonus credits, once. Trial credits expire after 14 days. Put the app down for six months and the credits you bought are still there.

TRY IT WITHOUT AN ACCOUNT
Open the app and you have 2 trial credits to spend. No card, no email, no sign-up wall in front of the first question. Sign in with Apple or Google whenever you like — you get 3 more trial credits, and whatever is left comes with you.

IMAGES ON THE ENGINE YOU CHOOSE
Generate images with GPT Image 2, Gemini 3 Pro, Qwen Image 2 Pro, Grok Imagine, Venice SD3.5 or Gemini 3.1 Flash. Choose the quality and the shape, see the price before you generate, and get four images at once when you want options to compare.

ASK ABOUT WHAT YOU ARE LOOKING AT
Send a photo, a screenshot or a PDF and ask questions about it. A dying plant, a form you do not understand, a menu in another language, an error message on screen — ask about that thing rather than describing it.

TALK INSTEAD OF TYPING
Hold to record and speak. Your voice is transcribed on device, and you can read the text and fix it before it sends.

EVERY CHAT KEPT AND SEARCHABLE
History has no limit and costs nothing to keep. Search looks inside the message text, not just the titles, and shows each match in context so you can tell similar conversations apart.

NOTHING IS LOCKED
Every model, image generation, attachments, vision, voice input, full history and search are available to everyone from first launch. There is no Pro plan to buy and no feature that appears only after you pay. Your balance is the only limit.

WHY PER-MESSAGE PRICING
A subscription charges the same whether you send two messages a month or two hundred, and it pushes you toward one company's models. Prepaid credits do neither. A cheap model answers a cheap question for a fraction of a cent, an expensive model is there for the questions worth spending on, and the app tells you which is which before you commit.

PRIVACY AND CONTROL
Any conversation can be deleted, or all of them at once, from Data controls in Settings. It does not ask for contacts or location, and carries no advertising.

WHAT IT DOES NOT DO
It does not lock a model behind a higher tier, hold your history hostage, expire credits you bought, charge you for a reply that failed, or auto-renew anything. If a feature is in these screenshots, it is in the app for everyone.

WHO IT IS FOR
People who want the good models without four subscriptions. People who used a free tier, hit the wall, and did not want a monthly plan. People who care what a tool costs to run and want that number on screen instead of buried in a dashboard.
