  • See what to change

    Your AI spots weak periods and suggests which rules to adjust.

Let’s cap each position at 20% to test whether that reduces concentrated losses. I’ll create v2 and compare it under the same conditions.

Keep v1 and backtest v2 with that change.

A few things to know

Can I use Vesist right now?

Not yet. We’re collecting waitlist signups ahead of the Vesist launch. The screens on this page illustrate the planned experience. Joining does not create a product account or guarantee access.

Do I need to code or have a trading strategy?

No coding is needed for the experience we’re building. Start with an investing style, then ask your AI to create an agent and explain or adjust its rules.

Will my agent trade with real money?

The first version focuses on backtesting with historical data and paper trading with virtual money. You can see trades in real US stocks and track simulated performance. Live trading and brokerage connections are not planned for the initial release.

Which AI assistants and markets will it support?

We’re planning integrations with Claude, ChatGPT and Muse, starting with US stocks. You’ll create, test and refine your agent through the AI you already use. We welcome users in the US and Korea. Support for Korean stocks is not planned for launch. Details for each AI integration will be shared before release.

When will it launch, and what will it cost?

The waitlist is free. We’ll share the launch schedule and product pricing once they’re confirmed. Opt in to launch emails to hear when invitations are ready.
