Sinaps — a builder for personal AI agents with memory. Describe a task in one paragraph — get your own AI agent trained on your documents. Or pick a ready-made expert from the marketplace: Nutritionist, Lawyer, Networker. Every agent remembers your story, cites its sources, generates documents — and works only for you. BUILD YOUR OWN AGENTS Type a name and a few paragraphs about what it should do — Sinaps builds the prompt for you. Drop in PDFs, Word files, notes — your agent studies them and cites them in answers. You get a personal expert on any topic in under a minute: an English tutor based on your textbooks, a product assistant based on your specs, a coach based on your journal. Anything. READY-MADE AGENTS IN THE MARKETPLACE Lawyer — drafts complaints, reviews contracts, writes appeals to authorities. Cites Russian law, generates Word documents. Networker (NEW) — a personal CRM for relationships. Remember who promised what, when you last met, people's interests. Assistant — your universal helper for everything else. PLATFORM CAPABILITIES — Long memory. Agents remember what you discussed a week or a month ago. No more re-explaining context. — Your knowledge base. Upload PDFs, DOCX, TXT — your agent will cite your documents in its answers. — Cards in chat. Structured replies: food logs, calendar events, source citations. — Calendar from chat (NEW). Ask to add a meeting — the event lands in your system calendar with one tap. — Voice input. Speak instead of typing. — Photos and images. Send a picture of food, a document or a moment — agents see and respond. — Word documents. Generate ready .docx files straight from chat (claims, applications, reports). — Pin your favorites. Most-used agents always one tap away in the side menu. — Russian and English (NEW). Full interface and conversation in both languages. WHY SINAPS This isn't yet another GPT chat where you re-explain who you are and what you want every single time. This is a platform where every agent has its own specialization, its own knowledge base and its own memory of you. The Lawyer knows the law. The Nutritionist understands food. Your own agent knows you. Transparency. Every meaningful answer shows where the information came from — source citations. Privacy. Your data is yours. Not sold. Not shared. Not used for training. Contacts and calendar sync only on your explicit consent. WHO IT'S FOR People who want an AI helper for a specific task, not a generic do-everything bot. People who track nutrition, deal with legal questions, or work with a large network of contacts. People who have their own documents, notes and materials — and want AI that actually works with them. Start free. Build your own agent or pick one in the marketplace — and have your first conversation that's actually remembered. Sinaps. Personal AI agents that remember.
