TL;DR
- →ChatGPT — best for one-off queries, advanced coding, English-focused creative work.
- →Synaps — best for everyday use: remembers context across sessions, ready specialized agents, custom GPT builder. Free.
- →Price: ChatGPT Plus $20/month, Synaps — free.
What's ChatGPT
ChatGPT is OpenAI's AI chat, launched November 2022. Uses GPT-4 / GPT-5 (depending on subscription tier). Available in web and mobile.
Free tier gives limited GPT-4o access. ChatGPT Plus at $20/month unlocks GPT-5 and Custom GPTs builder. Plus has «persistent memory» — but it works differently than Synaps memory: ChatGPT stores short «facts about user» rather than structured context.

FAQ
Is Synaps using the same model as ChatGPT?+
By default Synaps runs on GPT-5 — the same model as paid ChatGPT Plus. Additionally there's a switch to Claude Sonnet. The difference isn't in the model but in the infrastructure: memory, agents, knowledge bases — that's Synaps's layer on top of the base model.
What about ChatGPT's «Memory» feature?+
ChatGPT Plus has «Memory» — a feature that stores short facts («user likes Python»). But it's not structured long-term memory: ChatGPT doesn't remember context of a specific dialogue a week later, doesn't store documents as part of a knowledge base, isn't tied to a specialized agent with accumulated expertise.
Is Synaps really free?+
Yes. No subscriptions, no trial periods. All agents, builder, voice input, document generation — free. No ads.
Which is better for coding?+
For serious development — ChatGPT (especially with Code Interpreter). For day-to-day tasks (explain code, debug, simple script) — Synaps handles fine. If coding is your main use case, having ChatGPT Plus alongside makes sense.
Can I create custom AI agents like Custom GPTs?+
Yes — Synaps has a custom AI agent builder, free for everyone (Custom GPTs in ChatGPT require Plus subscription). Describe the task in plain text, upload documents, get a personal expert in a minute. No code.
