I built Chartself after realizing my own trading losses kept following the same pattern: revenge trading after a bad day, ignoring my own risk rules under pressure, trading worse at certain times without even noticing. Chartself uses AI to catch those specific costly habits automatically and puts a real dollar figure next to each one, so the cost is impossible to ignore. You can log trades manually, through a natural language AI chat, via CSV import, or automatically through broker sync with Binance, Kraken, and Luno. The AI runs on your own API key, so your trade data never trains anyone's model. It started as a tool just for myself, and the free tier is genuinely unlimited, not a trial, because I wanted other traders in the same spot to actually be able to use it without hitting a paywall on day one.
