What's the builder
The AI agent builder in Synaps lets anyone assemble a personal AI expert without programming. Describe what the agent should do, upload documents from your domain if needed — and in a minute you get a ready specialist with its own knowledge base and long-term memory.
Unlike general-purpose AI chats, your custom agent:
- Remembers your context — across dialogues, no need to re-introduce yourself
- Knows your documents — if uploaded, the agent references them in answers without mixing sources
- Has its own specialization — tuned to one domain, doesn't drift into generic responses
- Works on all devices — web app, iOS, Android, automatic sync
- Free — no subscriptions or trial periods

How to build an AI agent — 4 steps
Open Synaps
Go to the app (web / iOS / Android) and tap «Create agent».
Describe the task in plain text
Tell what your agent should do — like talking to a friend. Example: «Email assistant that writes business emails in my style».
Upload documents (optional)
PDF, Word, TXT — anything AI should know about your domain. Files become a personal knowledge base for this agent.
Done — your agent is ready
AI tunes instructions, picks tools, creates an avatar. Ready to use immediately.
What's inside an agent
- System prompt — instructions for the base model (GPT-5 or Claude). AI generates the prompt automatically from your description.
- Knowledge base (RAG) — uploaded documents split into chunks and indexed as embeddings. AI retrieves relevant fragments as context per query.
- Memory — structured records about you and dialogue history. Stored across sessions, accessible only to this agent.
- Tools — .docx generation, voice input, photo analysis, web search. Wired in as needed.
FAQ
Is this like Custom GPTs?+
Essentially yes — a builder for personal AI agents. Key differences: 1) free (Custom GPTs require ChatGPT Plus at $20/month), 2) built-in long-term memory across sessions, 3) generates .docx documents out of the box, 4) native iOS and Android apps, 5) works from Russia without VPN.
Do I need to know how to code?+
No. The builder is no-code — describe the task in plain text, AI configures the agent itself. If you want, you can edit the system prompt manually, but that's optional.
How many agents can I create?+
Unlimited. Create as many as you need — all live in your marketplace and sync across devices.
Can I upload my own documents?+
Yes. Supported: PDF, Word (.docx), TXT, images. Files go into the knowledge base of this specific agent — other agents don't see them. Up to 50 MB per document.
Does my agent remember conversation history?+
Yes. Each agent has its own long-term memory — remembers your goals, past dialogues, work context. Nothing is lost between sessions.
How much does it cost?+
Free. No subscriptions and no paid features. Creating agents, uploading documents, long-term memory, generating .docx — everything is included.
