Join us for a June evening of raw technical deep dives, live code demos, and peer-to-peer networking. This month, we are hosted by Relay Financial! And we’re thrilled to be supported by PostHog. As always, AI Tinkerers Toronto is produced by the Human Feedback Foundation.

AI Tinkerers is a meetup exclusively for practitioners actively building with foundation models and generative AI. We prioritize technical depth, code walkthroughs, and the Homebrew Computer Club ethos. This is a forum for engineers, researchers, and developers to share what they are building under the hood.

While we keep the theme open for June, we especially welcome finance-focused AI use cases. If you use Posthog in your stack, we definitely want to hear about it!

🎤 Call for Demos

We are looking for presenters to share their work. Demos are limited to 5 minutes and must focus on implementation, architecture, and code. We have a strict policy against product pitches and marketing slides—no PowerPoint allowed. And we mean it: Strict no deck rules apply!! We’ve had people sneak in with decks before and please believe it when we say this: feedback from the attendees always calls this kind of thing out. People don’t want decks; everyone prefers a tech demo, even if messy. We want to see your messy experiments, agentic workflows, and technical discoveries.

Your demo should answer: “How did you build this interesting thing?” not “Why should someone use this product?” Please cover what you built, how you built it, and what another builder can reuse or avoid. Finance-focused use cases and integrations with Posthog are highly encouraged!

• **Demo submission deadline is June 21st EOD (Sunday). Hear back on June 23d, present on June 30th.
• **Submit Your Demo Proposal Here

🗓️ Event Details
