Where Koyfin is stronger
- Ten years of financials and estimates with global company coverage, far beyond our data depth.
- Advanced charting, unlimited custom dashboards, custom formulas and templates.
- A genuine research terminal, which is a different and more powerful class of tool for studying markets.
- Adviser tiers with client reporting and custodian integration that we do not offer at all.
Where Vestiio is stronger
- Scouts revisit your investment questions every Sunday, retain research history, and surface meaningful changes with source quotes and links. Premium includes three personal Scouts; house Scouts are available on every plan.
- Built around the portfolio you hold, with read-only broker syncing.
- AI chat that knows your holdings, scores, thesis, risk, and the macro regime.
- 13F Fund Explorer and an analyst feed scored on predictive skill.
- Portfolio Radar: news about your holdings, with AI marking which stories are material.
- Half the price of Koyfin Plus at our entry tier, and well under Premium at every tier.
- A share page in percentages, so others see how you invest without seeing how much you have.
- A month-by-month activity record on that page: what you bought and sold, how your thesis changed, and a written summary of the month.
- Swiss-hosted, with portfolio contents never used to train models.
