ChatGPT is a chat box. Hermify is an assistant that actually remembers you.
If you already pay $20/mo for ChatGPT Plus, you have probably noticed it forgets every conversation, lives in a tab you have to remember to open, and gives you no real control over the underlying model. Here is how Hermify is different — and why it costs the same or less.
ChatGPT does not reliably remember your projects, preferences, or context across sessions.
ChatGPT lives in a browser tab. Hermify lives on Telegram, where you already are every day.
ChatGPT locks you into one provider. Hermify lets you bring any key and switch models freely.
ChatGPT's "memory" feature is opt-in, fragile, and limited to short fact lists. It does not preserve full conversation context across sessions, and it routinely loses important nuance.
Hermify is built on persistent memory by default. Every conversation builds on the last — preferences, projects, decisions, and ongoing context all carry forward without you having to re-explain them.
ChatGPT only works inside a browser tab or its dedicated app. To talk to it you have to remember to open it, navigate, and start over.
Hermify lives inside Telegram, the app you already use to message friends and family. Voice messages, text, photos — anywhere your phone goes, your assistant goes.
ChatGPT Plus locks you into OpenAI's models, OpenAI's pricing, and OpenAI's policies. You cannot switch the model, you cannot bring your own key, and you cannot pay for usage.
Hermify Starter ($19/mo) lets you bring your own key from OpenAI, Anthropic, OpenRouter, or any compatible endpoint. Switch models whenever a better one ships, pay your provider directly, and keep full control of usage.
ChatGPT supports custom GPTs, but they are siloed: each lives in its own conversation thread and they do not share memory between them.
Hermify skills are first-class extensions of the same assistant. Teach it how you write emails, summarize meetings, or research a topic — and that skill is available in every future conversation, with the same memory and context.
ChatGPT Plus
$20/mo
Single user, weak memory, no Telegram, no BYOK, no custom skills with shared memory.
Hermify Starter
$19/mo
BYOK any provider, full persistent memory, Telegram included, custom skills, multilingual.
Hermify Pro
$29/mo
Same price tier as ChatGPT Plus, but with managed AI access, memory, Telegram, and skills.
Yes. For users who want persistent memory, Telegram access, custom skills, and the option to bring their own AI key, Hermify is a more complete personal AI than ChatGPT Plus at a comparable price.
Yes. With BYOK on Starter, you can plug in any OpenAI model — including the same one ChatGPT Plus runs. You can also switch to Anthropic, open-weight models via OpenRouter, or any compatible endpoint.
Hermify is built around persistent memory as a core abstraction, not an afterthought. Every conversation reads and writes to the same long-running memory store, tied to your account.
Telegram is something you already check daily. Hermify lives there as another contact, so the friction of "opening the AI app" disappears. Voice messages, photos, group chats — everything works.
Hermify Starter ($19/mo) is cheaper than ChatGPT Plus ($20/mo) and includes memory, Telegram, and skills. Hermify Pro ($29/mo) is the cleanest non-technical path with managed AI access included.
Yes. Many users start with both, see how memory and Telegram change their daily AI use, then cancel ChatGPT Plus once Hermify becomes the default.
