Turn an explanation into a narrated video: the AI assistant writes the script, voices it, and animates your scene to match. NARRATED VIDEOS • Tap + in the AI assistant and choose Narrated video, or just ask for narration. Edit the script line by line, or ask the assistant to revise it • Pick from 31 voices, set the speed, and narrate in any of 7 languages. Listen to a sample before you choose • After synthesis, the assistant animates to the audio and test-renders until it lines up. If an animation runs late, the narration page shows where • Change one line and only that line is synthesized again • Export an MP4 with the voiceover included • Narration runs up to about 2 minutes and uses AI credits SOUND IN YOUR SCENES • add_sound() now works: audio you add to a scene is mixed into the video, in the preview and when you export FIXES • Going back to the project list or switching projects now stops the preview and voiceover playback

Use your own fonts in scenes: download them from Google Fonts, or add font files to a project. FONTS • manim_fonts now works: with RegisterFont("Poppins") as fonts: downloads the family from Google Fonts, and Text(…, font=fonts[0]) uses it. Downloaded fonts stay on your device, so later runs don't download them again • Put a .ttf or .otf file in your project and register it with register_font("fonts/MyFont.ttf"), the same as in desktop Manim • If the family includes bold and italic styles, weight=BOLD and slant=ITALIC work too • Family names must match Google Fonts exactly, including capitals, for example "Open Sans"

Fixes from your feedback: Tex keeps its spaces and line breaks, Replace goes through matches in order, and imported .py files open as code. FORMULAS • Tex and Title now lay out text the way LaTeX does: spaces between words are kept, letters stay upright, and \\ starts a new line. Inline math in $…$ still works EDITOR • Replace now goes through the matches in order instead of skipping one • .py files you import (Import → Import from Files, or drag them in on iPad) go into the project folder next to main.py and open in the editor, ready to run. Other files still go into assets • On iPad, Editor Settings has a new tip: if a hardware keyboard misbehaves, try turning off AssistiveTouch in Settings → Accessibility → Touch FIXES • On iPad, if you pause one audio file and open another, Play now plays the one you opened • In paid courses, the locked intro card opens the unlock screen instead of doing nothing

Sync your projects with iCloud, find and replace in the editor, and type in any language. ICLOUD SYNC • Turn on Mine → General → Sync projects with iCloud to keep your projects in iCloud Drive and up to date on all your devices. It's off by default • Projects also show up in the Files app under iCloud Drive → Manim Tutorial, so you can edit code or drop in assets from a Mac • A cloud at the end of each project row shows whether it has finished syncing • If two devices change the same file, both versions are kept: the other one is saved next to it as a conflicted copy • Rendered videos stay on this device and aren't uploaded; use Export to save or share them EDITOR • Find and replace: tap the magnifying glass, or press ⌘F / ⌥⌘F on a hardware keyboard (⌘G for the next match) • Chinese, Japanese, Korean and other keyboards now work in the code editor, for comments and on-screen text. On a hardware keyboard, ⌃Space switches input sources again and code completion moves to ⌥Space AI ASSISTANT • On iPad, Ask AI to fix now appears when a render fails, and the assistant gets the full traceback IPAD WORKSPACE • The AI column starts hidden and remembers whether you left it open

Tap in math and physics symbols when you talk to the AI assistant, and give the editor more room on iPad. SYMBOL BAR IN THE AI ASSISTANT • While you type a message, a row of math and physics symbols appears above the input box — tap one to insert it at the cursor • Tap the arrow on the left for more: Operators, Relations, Greek, Calculus, Sets & Logic, Geometry, Arrows, Physics, Super/Subscript and LaTeX snippets • The symbols you use most move to the front • Works with a hardware keyboard on iPad too IPAD WORKSPACE • Move the preview and console panel to the right column, below the AI assistant, so the editor gets the full height. Use the new button in the panel's title bar; your choice is remembered • In portrait on an 11-inch iPad, the right column now fits the screen instead of running off its edge

Write formulas with Typst, rename and export projects on iPhone, and save videos straight to Photos. NEW • Manim 0.21.0 with Typst: use Typst and MathTypst for text and formulas — a cleaner, easier-to-read alternative to LaTeX, rendered right on your device • Rename and duplicate projects on iPhone: swipe a project left for Rename, or long-press it to rename, duplicate, export or delete • Export project as .zip to back up or share a whole project — your code and assets, without the rendered videos • After exporting a video, tap Save to Photos in the share sheet EASIER TYPING • While you type code on iPhone, a Hide Keyboard button appears in the run bar, so the tabs below are always within reach • In the AI assistant, hide the keyboard with its button, by tapping the conversation or by pulling down FIXES • Renaming or duplicating a project now saves your unsaved edits first • In a short AI conversation, the messages no longer jump down when the assistant finishes thinking

Meet the AI assistant: describe an animation, and it writes the Manim code, runs it on your device, checks the result and fixes what's off. AI ASSISTANT IN THE WORKSPACE • Ask for a scene in your own words, attach a sketch or a photo, or point it at a file with @ — it edits your project and test-renders until it looks right • Keeps working while you switch apps; a Live Activity shows its progress and a notification tells you when it's done • Choose how hard it thinks, stop it anytime, or edit your last message and send it again • Every device starts with 1,000 free credits. "All Courses" now includes 5,000 AI credits a month for 12 months — your first month is prorated by the days left when you buy and the last month tops up the difference — and credit packs are available in the app SIGN IN, IF YOU LIKE • Optional sign-in with Apple, Google or email keeps your credits and monthly course credits in sync across your iPhone and iPad • Manage sign-in methods or delete your account anytime in Mine → Account MORE • Now in Traditional Chinese, Japanese, Korean, Spanish and Brazilian Portuguese — pick the app's language in Mine → Language • Light mode follows your system setting, with a new light code editor theme • Pick the quality when you export; the scene is re-rendered in high quality only when needed • On iPad, the AI assistant sits in its own column next to the editor, with preview and console in a resizable panel below • Course code now opens straight in the Workspace as its own project • Course videos now download on demand (free courses download automatically on Wi-Fi, paid courses after you unlock them), so the app is much smaller to install • New Render Benchmark in Mine → Tools: time how fast your device renders and compare its output frame by frame with native Manim on a Mac

See how far a render has got, stop it anytime, and set up the code editor the way you like it. • While a scene renders, the preview shows how far along it is, and a Stop button ends it right away • New editor settings: choose the font, font size and line spacing, and turn on line numbers, current-line highlighting, a line-length guide or visible spaces. With a keyboard, ⌘/ comments or uncomments the selected lines • The Workspace is still free to write, run and preview. On the free plan, videos and images you export carry a small app badge — a one-time Workspace unlock removes it, and it's already included if you've unlocked all the courses • Fixed a crash when pasting a long block of code on iPad, and an error that could show up when coloring part of a formula

Faster rendering and a round of fixes. • Videos render much faster — about 5× at 1080p — and combined or cut shapes come out with smoother edges • Text colors and font styles now display correctly (they used to come out plain white), and a scene with no animation gives you a still image instead of an error • Workspace fixes: creating a new project no longer shows a "file not found" error, deleting a project asks you to confirm first, pasted code with tab indentation just works, and the black strip at the bottom of the screen with an external keyboard on iPad is gone

The Playground grows up: it's now a Workspace — real projects, multiple files, and your own assets. PROJECTS, NOT JUST SNIPPETS • Organize your work into projects, each with its own files and assets folder • Import your own SVGs and images and use them in scenes — SVGMobject("assets/x.svg") and ImageMobject just work • Split your code across files and import between them • On iPad, a three-column layout puts files, editor, and results side by side A SMARTER CODE EDITOR • Autocomplete now appears right at your cursor, VS Code style, with color-coded icons for classes, functions, and parameters • Suggestions are ranked by what Manim code actually uses, so the name you want is usually first • A signature hint shows the parameters of the call you're inside, with the current one highlighted • Accepting a suggestion replaces the whole word — no more broken half-typed names • Undo and Save buttons right in the editor toolbar • Hardware keyboard support: arrows, Tab, Return, and Esc drive the suggestion list CHOOSE YOUR RENDER SIZE • New render settings: 480p, 720p, or 1080p, landscape or portrait • Set a default for everything, or override it per project • Your own config.* settings in code still take priority A CLEANER PREVIEW PLAYER • Rebuilt video player keeps the controls below the picture instead of on top of it, so nothing covers your animation • Scrub smoothly even inside the results panel NOW IN SIMPLIFIED CHINESE • The whole interface follows your system language — English and Simplified Chinese FIXES • Fixed a double keyboard shift that pushed content off-screen on iPad in landscape • Errors from a previous run no longer linger in the console after a successful one • PNG sequence output now respects the full duration of a static wait() • The suggestion popup now fits itself to the available space instead of going off-screen when the keyboard covers most of the display Join our Discord community directly from the app to ask questions, share your Manim creations, and connect with other learners.
