This just blew my mind 🤯 I asked Opus 5.5 to make an ad for one of my apps (my file converter, How to Convert). It made this. What do you think?

lsa lists and reopens sessions across Claude Code, Codex, and pi with one command -- continuing in a different agent stops meaning starting over. Same idea behind hev-query: session history already has the answer, it just needs to be searchable instead of remembered.

This is what consistently blogging and doing pSEO does over time. I get ~400 visits from Google each day And I don't have to post here to get it. Has been a lifeline for me. This year has been TOUGH as an indie dev. It feels different from when i first started. I used to go viral often on reddit

I made a command to continue a Claude Code conversation in Codex It's called lsa. It also lists and reopens your sessions across agents. Free and open source. Star it if you'd use it: github.com/jakemanger/lsa

This is an app I made. It turns your screen recordings into demos that look like an Apple ad I launched it 4 months ago and 281 people have bought it

Me (every day): "I can't be bothered filming another screen recording" Type into claude: "Film a screen recording showing how to calculate sum in google sheets" (for my computer-illiterate dad) Claude: records a demo, types and clicks everything, and exports it ready to send

I made ls for agent sessions: lsa I opened my terminal the other day and couldn't remember which agent I'd last been using. Instead of opening Claude, Codex and Pi individually to check, I thought it'd be nice to just `ls` my conversations like I do my files.

I made a screen recorder that AI agents can use to film their own demos This is Codex drawing the Mona Lisa in Illustrator while ShotGlass records it, zooms in on the mouse, and exports the video

4 months ago I launched a screen recorder called ShotGlass I was sick of every demo looking like the same Screen Studio template Today 280 people have bought it, it does 3D scenes and auto zooms, and an AI agent can film and edit the demo for you

A random AI emailed me today. I didn't ask it to. Didn't even know it existed. It found a question I posted on HackerNews, answered it, then filed a support request with Claude to make it clearer for people in the future. Didn't want anything in return. Just helped and moved on. AI free will?

Jake Manger @jakemanger.bsky.social · 19/09/2026
One amazing thing about agents is you can spin up automated tests for things super easy: This is a test for click precision and timing in my screen recorder, ShotGlass. Clicks now happen EXACTLY when and where you did them (the replaced larger cursor was out by a few ms before)!

Does this mean it's fine to use Claude subscriptions with third party harnesses? I've been curious about using a claude subscription with OpenCode, Pi and some other third party harnesses. If you remember, there was a lot of chatter about a ban on third party harnesses.

One thing I've learnt coding with AI Agents: Edit what it's made and cut the crap. It reminds me a lot of editing in writing.

Shipped multi-language support in my file converter app How to Convert now works in 11 languages (noticed most of my users aren't English speakers so just translated everything) German & Brazilian users (there's a lot of you!) → let me know if the translations suck

Jake Manger @jakemanger.bsky.social · 15/09/2026
Just shipped multi-file type batch conversions in How to Convert Drop 30 PNGs, 10 Webps and 10 HEICs → get 50 JPGs Drop 10 MP4s, 5 MOVs & 5 AVIs → get 20 GIFs Works with any almost any file type (images, documents, videos, audio, emails, comics and more)

You know those file converter sites on Google? Most of them are sketchy as hell. You upload private files to some random site and hope nothing bad happens. So I built a file converter that runs completely locally. Supports 5,438 different file conversions (yes really) Crossed 3,600 users today!

How did the iPhone get more expensive than the Macbook Pro?!? $3,500 vs $3,200 (AUD) is insane Was excited. Now I can never justify it sadly

My app filmed its own docs With ShotGlass's new MCP integration, I just asked it to "Film demos of exploring and using every menu item with ShotGlass". Then, it started churning them out.

Jake Manger @jakemanger.bsky.social · 10/09/2026
I built ShotGlass, a macOS app for polished screen recordings. Now Claude and Codex can use it too. I asked Codex: “Film yourself drawing some art in Adobe Illustrator with ShotGlass.” It opened Illustrator, made the artwork, recorded the whole thing, and handed back this shotglass.app

@iHaadiYT just reviewed my app ActivityLine on YouTube It's a menu bar line that shows which app is eating your RAM, CPU or GPU. It's only 2.3 MB and built in Swift He replaced his old activity monitor with it www.youtube.com/watch?v=zJx...

My file converter How to Convert is going multi-language! 9 new languages are live on the site. The app follows shortly. Is taking quite a bit of time even with AI to help translate, but since the app is used in almost every country, I think it's time non-english speakers get a native experience

When I first started app development, Compresto (then CompressX) by @hieudinh_ was the kind of app I could only ever dream of making. It was everywhere on my timeline. Even @rauchg (CEO of vercel) used it. I thought what made it useful?

If you’ve also had enough of Claude Opus 5’s smart ass and unreadable commentary, Type this into Claude code. My old friend 4.6 is back and life is good again. I’ve never felt more gaslit by software.

I built an app that turns screen recordings into Apple-style product demos. Every recording automatically gets the rounded corners, shadows, and 3D animations you see in Apple ads. No editing. No After Effects. Just record and export.

I spent 6 months building ShotGlass. Then I posted v1 to r/MacApps and the first sale came through within an hour. Six months of wondering whether anyone would care, followed by one very good notification.

Jake Manger @jakemanger.bsky.social · 29/08/2026
Claude Code just hit the session limit after 1 prompt. Didn't even finish the task. After ~ 5 mins of it running useless commands. Happened twice now on the MAX plan. Meanwhile I've had Codex running for days on end without hitting limits. Something's not adding up here.
Notification alert indicating the user has reached their monthly spend limit, with session reset details for Australia/Perth.

v1.0.1 of ActivityLine is out. It adds a configurable Update Rate, Time Window and lets you Exclude certain apps. Now it's easier to see when and what app used all your RAM, Network, CPU or GPU. AND KILL IT when it does

Also think I should advertise to cocktail and bartender communities? I’m an app developer, and I get about 6-7 of these emails every day. How are they so bad?! My apps a screen recorder, and its name is ShotGlass.

My new app ActivityLine made it to the top of r/macapps! I routinely run out of RAM, CPU or GPU resources and wanted to know when it happens and what app was causing it. But, I didn't want my menu bar to turn into a row of numbers.

I made a new personal site that morphs into each of my projects as you scroll. Each website I've built transitions into the next one on the page. Pretty happy with how it turned out. jakemanger.dev

My file converter app has had 185,000 site visitors and earned $85k. I built it before vibe coding was a thing. Despite a mountain of AI-generated clones popping up, it's still doing well. Two reasons why:
