AE Doctor scans your machine, your plugins and your projects — finds exactly what's slowing down or crashing After Effects, and shows you the exact fix. One click applies it with Pro.
The smartest way to diagnose optimize repair supercharge your After Effects.

Stop guessing. AE Doctor finds the exact cause — and shows you exactly how to fix it (Pro fixes it for you).
From one-click diagnosis to ring-0 hardware telemetry — AE Doctor covers the whole stack, inside the app you already work in.
One click inspects your OS, RAM, GPU, AE version, disk cache and preferences — then grades everything green, yellow or red, with a "since your last scan" diff.
After Effects' native auto-save buries your SSD under dozens of bloated, redundant copies. AE Doctor saves your real project on a clean timer — or every N clicks — so you never lose a keyframe without suffocating your disk. One file, zero clutter.
Hit a cryptic Error 5027:12? AE Doctor inventories every script and plug-in on your machine — hundreds of them — and flags duplicate conflicts, 32-bit relics and version clashes instantly, free. Pro reveals the full install path and isolates the corrupt .aex or .jsx file with one click, so you never have to dig through hidden Program Files\Adobe folders yourself. 100% local.
.aex / .jsx in one clickDeep-scans your open comp for the real timeline-killers — 8K precomps, layer bombs, heavy motion-blur stacks and long-GOP codecs (raw MP4s, WhatsApp clips) that choke playback. Free shows you exactly what's wrong; Pro applies the exact fix — proxy, pre-render or transcode — tuned to your actual hardware, and every proxy or transcode can be undone in one click if you change your mind.
Don't let 50 Chrome tabs and Electron apps (Claude, Discord, Spotify) choke your preview. One switch force-flushes their bloated working-set memory into the Windows standby cache and parks them on your CPU's efficiency cores — nothing closed, everything reversible. Reclaim 3–8 GB+ of RAM instantly and raise After Effects' scheduling priority while exempting it from CPU throttling.
Real-time power draw and CPU/GPU temperature stream free for every tier — the same class of sensor data Fan Control and HWMonitor read, through the same native, low-level driver access those tools need. Pro unlocks the rest of the monitor (fan RPM, per-DIMM RAM, storage health, live per-app RAM view) plus AI Diagnostics, which translates all of it into a plain verdict for the render you're about to hit: "excellent environment for heavy rendering," or an early warning before it costs you one.
Paste any cryptic AE error — fuzzy search matches it against 100+ documented issues and shows the exact cause, free. You could paste the same error into ChatGPT and get a similar-sounding answer. What you won't get from ChatGPT: a watcher that catches the error popup automatically, before you've even alt-tabbed to look it up, and a "Fix it for me" button that applies the repair directly inside After Effects — no copy-pasting, no guessing which generic step actually applies to your AE version. Free for every user, no upgrade required.
Hit an error nobody has seen before? One button sends it — with a screenshot and your full hardware spec attached automatically — straight to the support Discord as a tracked forum thread. No forms, no log hunting, no "please attach your specs".
AE Doctor remembers every scan and diffs them — so when something breaks, you know exactly what changed.
Purge RAM + disk cache, raise memory reservation, relocate cache drives, disable a broken plugin — every fix is a single button, applied through AE's own scripting engine.
Scan and diagnose forever, free. Upgrade when you want AE Doctor to do the fixing — and the boosting — for you.
Crashed renders cost you hours — Pro's crash-risk advisor flags the problem before you hit render. One skipped all-nighter pays for a year of Pro many times over.
Know exactly what's wrong. Forever free.

AE Doctor isn't just a simple script. It's a deep system-level C# service that monitors your hardware and optimizes Windows for After Effects in real-time. (Windows 10/11 only — macOS support is under evaluation for future releases.)
Not a RAM cleaner — Task Manager literally can't do this. Windows has no built-in way to hand back an app's memory without closing it; it takes direct calls to low-level OS memory and scheduling APIs (what Windows calls EcoQoS). ICU Mode forces background apps (Chrome, Discord, Spotify) to release memory they're hoarding and moves them onto your CPU's efficiency cores — reclaiming 3–8 GB+ and raising After Effects' scheduling priority while exempting it from CPU throttling, without closing a single window or touching system stability.
Reads your footage's actual file headers, not just its file extension. It opens the raw MP4/MOV data to catch Long-GOP codecs (H.264/HEVC — footage where every frame depends on the ones before it, which is why it stutters when you scrub) plus 8K precomps, layer bombs and heavy motion-blur stacks. Free tells you exactly which problem it found; Pro renders the fix — proxy, pre-render or transcode — for you, and if it's not what you wanted, one click removes the proxies or reverts the transcode. Nothing is a one-way door.
The same sensor data Fan Control shows you — plus the one thing it can't. Total power draw and CPU/GPU/VRM/NVMe temps are real and free for everyone. Pro unlocks the rest — fan RPMs, per-DIMM RAM, per-drive storage health, and exactly which background app is hogging your RAM right now — and AI Diagnostics watches all of it together (heat, RAM pressure, storage fill) to give you one plain-English verdict: "excellent environment for heavy rendering," or an early warning before it wrecks your render.
Free tells you what to change and where. Pro just changes it. The ExtendScript engine — After Effects' own internal scripting language, the same interface Adobe uses to build its own automation — opens the right preference, sets the right value, and confirms it, for memory reservations, cache paths, corrupt preferences and buggy plugins. No hunting through nested menus mid-deadline, no risk of a typo in a setting you rarely touch.
Don't just take our word for it. See how AE Doctor is saving professionals countless hours of troubleshooting and frustration.
