Hey Product Hunt 👋 I’m Taha, the maker of Synthora. Synthora starts from a simple product principle: an investment tool should show its work. It’s a free, browser-first investment planning tool built around transparent calculations rather than black-box market predictions. With Synthora you can: • plan a conservative portfolio • track holdings and portfolio history • see allocation drift and rebalance through new contributions • run historical backtests • explore Monte Carlo scenarios • inspect the assumptions and data behind the results A few principles were especially important while building it: Your personal financial data stays local by default. Observed market history and modeled assumptions are treated differently and clearly labeled. If historical data is missing, Synthora would rather tell you it is missing than quietly invent a number. And instead of pretending to predict the market, it tries to make the reasoning behind a financial decision understandable. Synthora is Persian-first and built with the Iranian investment context in mind, while the interface also supports English, Russian, and Chinese. For this launch, the feedback I care most about is **trust and clarity**: Can you understand why Synthora produced a result? Can you distinguish observed data from assumptions? And after using it, is there anything you would need to see before trusting the numbers enough to use them in your own planning? Would genuinely love to hear what works, what feels confusing, and what you think is missing.
