- Last year, I made a YouTube documentary series showcasing the prolific corruption in a small city government. I downloaded all the city government meetings, used Whisper to transcribe them, and then set up a basic RAG so I could query across a decade of committee meetings (around 1 TB of video). Once I got the timestamps that I'm interested in, I then have to embark on a tedious manual process of locating the file, cutting out a few seconds/minutes from a multi-hour video, and then order all the clips into a cohesive narrative.
These seem like problems that LLMs are especially well-suited for. I might have spent a fraction of the time if there was some system that could "index" my content library, and intelligently pull relevant clips into a cohesive storyline.
I also spent an ungodly amount of time on animations - it felt like "1 hour of work for 1 minute of animation". I would gladly pay for a tool which reduces the time investment required to be a citizen documentarian.
- I think this is a great endeavor. I was thinking about a channel that I like watching on YouTube. They travel to exotic places by boat and film themselves, nature documentary style. To make good videos requires going to these places, a ton of filming, AND a ton of editing. They put out a video every 2 weeks or so on their trips. I imagine the editing is the hard part.
This is a long winded way of saying that I think creators need what you're making! People who have hours of awesome footage but have to spend dozens of hours cutting it down need this. Then also people who have awesome footage but aren't good at editing or hiring an editor, same thing. I'd love to see someone solve this so that 90th percentile editing is available to all, and then it can be more about who has the interesting content, rather than who has the interesting content and editing skills.
- Hey, this is super cool. congrats on the product and the launch!
I'm building something exactly similar and couldn't believe my eyes when I saw the HN post. What i'm building (chatoctopus.com) is more like a chat-first agent for video editing, only at a prototype stage. But what you guys have achieved is insane. Wishing you lots of success.
to healthy competition!
- I just signed up for a Creator plan, but it looks like the automated "Thank you for being a Mosaic Creator" email going out is not configured correctly. Instead of having my company name, it referenced a different business name and description (that seems to exist/be accurate, so not a placeholder).
- Can it work for this use-case? I have lots of 15 seconds to 1 min duration videos) of my kids and want to upload them all (let's say 10 videos) and have the agent make a single video with all the best bits of them?

- > We got frustrated trying to accomplish simple tasks in video editors like DaVinci Resolve and Adobe Premiere Pro. Features are hidden behind menus, buttons, and icons, and we often found ourselves Googling or asking ChatGPT how to do certain edits.
Hidden behind a UI? Most of the major tools like blade, trim, etc. are right there on the toolbars.
> We recorded hours of cars driving by, but got stuck on how to scrub through all this raw footage to edit it down to just the Cybertrucks.
Scrubbing is the easiest part. Mouse over the clip, it starts scrubbing!
I’m being a bit tongue in cheek and I totally agree there is a learning curve to NLE’s but those complaints were also a bit striking to me.
- I like the tile-based workflow approach. I’m curious, is integration with tools like 11labs/cartesia or HeyGen on the cards? It would make it much easier to produce influencer-style POV/first-person content using digital avatars and cloned voice-overs.
Also, do you have an API available to trigger workflows programmatically?

- Really interesting direction.
The node-based canvas feels like a more scalable abstraction for video automation than the usual chat-only interface.
I’m curious how you’re handling long-form content where temporal context matters (e.g., emotional shifts, pacing, narrative cues).
Multimodal models are good at frame-level recognition, but editing requires understanding relationships between scenes, have you found any methods that work reliably there?
- I’ve had a lot of fun with Remotion and Claude Code for CLI video editing. I’ve been impressed with how much traditional video editing I can manage.
I will be checking this out!

- And what’s the plan for determinism? For repeat workflows it’s important that the same pipeline produces the same cut each time. Are node outputs consistent or does the model vary run to run?
- This website seems to be coded with AI. The sign up only works in Chrome not Chromium, and then I'm stuck forever at the step 3 of signing up

- did not get this part "After talking to users though, we realized that the chat UX has limitations for video: (1) the longer the video, the more time it takes to process. Users have to wait too long between chat responses. (2) Users have set workflows that they use across video projects. Especially for people who have to produce a lot of content, the chat interface is a bottleneck rather than an accelerant." what are you processing? frame by frame images?

- The home page is a big turn off. Change it.
- I just clicked the link and encountered a non-scrollable, dark, fixed content pane with loads of flickering images and scrolling text with random font sizes without much meaning. I felt imprisoned, subjected to unexpected suffering, can't scroll away, got scared and raced for the window close button, and then breathed easy.
- Very cool. It definitely feels to me that the power of pro tools should be available to more people with AI.
Would have been nice if there was a killer demo on your landing page of a video made with Mosaic.
- Have y'all talked with Max and the Ozone team? Suppose you would have lots to learn from them as you take on this space. Best of luck, video is hard!

- I absolutely love your approach of "expert tools". If I understand your approach, you aren't just feeding a video into a multimodal LLM and asking it "what is the bounding box of the optimal caption region?" -- you have built tools with discrete algorithms (using traditional CV techniques) that use things like object detection boxes + traditional motion analysis techniques to give "expert opinions" to the LLM in the form of tool calls -- such as finding the regions of minimal saliency + minimal movement to be the best places for caption placement.
If the LLM needs to place captions, it calls one of these expert discrete-algorithm tools to determine the best place to put the captions -- you aren't just asking the LLM to do it on its own.
If I'm correct about that, then I absolutely applaud you -- it feels like THIS is a fantastic model for how agentic tools should be built, and this is absolutely the opposite of AI slop.
Kudos!

- Hey, good luck with Mosaic.
Some feedback initially on the landing page, looks great but I thought that there is, for me, too much motion going on on the homepage and the use cases page. May be an unpopular opinion!
- Can you make this a desktop app?
I'm really tired of editing videos in the cloud. I'm also also tired of all these AI image and video tools that make you work over a browser. Your workflow seems so second class buried amongst all the other browser tabs.
I understand that this is how to deploy quickly to customers, but it feels so gross working on "heavy" media in a browser.

- Good luck. I've dabbled with this myself and ultimately decided that DaVinci Resolve would end up doing this natively. But then again they haven't yet so who knows!
Good luck with it, sincerely.

- Can we stop with the overloaded names? "Mosaic" is a well-known web browser.
