What we have been building at OpenCharts

We have been heads down for a few months, so this is a catch up on everything that has landed since May, plus a peek at what is running underneath it all. If you use OpenCharts already, most of this is stuff you can go try today. Here is the tour.

You can now create music inside OpenCharts. Describe the kind of track you want, in plain words, and Theo writes and performs it.

• Every prompt gives you two finished versions, each with its own cover art, so you have something to choose between.

• Write your own lyrics, let Theo write them, or keep it instrumental.

• There is a karaoke player with synced lyrics, and every track you make is saved in your own library.

• Put together a page in a few minutes and point it at your own custom domain or a short theo.fyi link.

• Analytics are built in, so you can see where your visitors are, what they click, and where they came from.

• You can capture leads straight from the page.

• Subject Lock keeps a product, logo, or mascot consistent across every image you make.

• Spot Edit lets you change one part of a picture and leave the rest alone.

• Ad Score checks your creative and flags anything off brand, Copy variants write the words, and Campaign Packs resize one design into every format you need.

• Connected Brand, Logo, Website, and Pitch studios that all share the same look.

• It now generates matching app icons too.

• Everything bundles into a brand book you can share with your team.

• Theo Reel and Video Studio. Describe a clip and Theo generates the video right in chat, in landscape or vertical.

• Enterprise Wiki. Paste a link and Theo turns it into a clean article. Build out a team knowledge base and, when you are ready, publish it as a public site on your own domain.

• Spreadsheet editor. A spreadsheet canvas that sits right next to your flowcharts, notes, whiteboards, and decks.

• Game Canvas (Beta). Now in testing: generate game ready assets from a prompt. It is early, and we would genuinely love your feedback.

• Telegram, leveled up. Theo in Telegram now sends a status the moment you message, delivers finished flowcharts, images, code, and videos right in the chat, and remembers you across conversations like the web does.

• Presentations. Brand Anchor locks a subject, style, or logo across a whole deck so it stays consistent, plus one click deck translation, a mode that restructures a deck into a proper pitch, and finer control over slide images.

• Code Canvas. Projects can now include a real database and user login, preview live at their own web address, rebuild a site from a URL, and pick up your brand from a guide you upload.

• Notes. Movie Mode turns your notes into a narrated video, and the AI panel and built in tasks both got a rework.

• Podcasts. The hub was redesigned into a Spotify style audio library that turns your notes into something you can listen to.

• Chat. Theo remembers you across conversations now, picks tasks back up where you left off, answers with citations, and builds real artifacts instead of just replying with text.

• Meetings. Share recaps with participants, get richer insights, and choose from a set of meeting mascots with different personalities.

• Theo Agents. Build your own always on, multi step agents from a Mission Control dashboard and a drag and drop designer.

Here is something most people do not realize. Every AI feature above runs on the same engine, hitheo.ai, our AI orchestration layer. Chat, research, code, voice, image, video, presentations, podcasts, notes, meetings, and the Telegram bot all sit on top of it. That is why the brand you lock in Image Studio shows up correctly in your presentation, why the assistant that helps you in chat is the same one that remembers you in Telegram, and why new capabilities tend to show up across the whole app at once.

The part worth knowing: that same engine is something you can build on, not just use. If you have your own idea, you can white label OpenCharts and run your own branded product on the same orchestration and billing, connect external tools and agents to your work through our public MCP server, or ship a real app with a database and live preview using Code Canvas. OpenCharts is the product, but it is also a working example of what you can build on hitheo.ai yourself.

We refreshed the look of the app and made Theo quicker and sharper under the hood. We also spent real time on the unglamorous work: smoother sign in, steadier presentations, code builds, and video, cleaner meeting connections, and a long list of smaller fixes, along with ongoing performance and security improvements.
