Everything about Serlinger Ai.

Four steps, start to finish:

Everything after step 3 runs on our servers, not your browser. You can close the tab or step away the moment you land on the progress page — it keeps working, and you'll find it finished (or still going) whenever you come back via your projects.

Paste any public YouTube URL and we pull the video, its title, thumbnail, and — if YouTube has computed it — the "most replayed" data for that video.

Enterprise plan only: skip YouTube entirely and upload a video file directly (MP4, MOV, MKV, or WebM, up to 2GB). Useful for recordings that were never made public.

Choose one or more length presets — 30s, 60s, 3 min, or 5 min — and how many reels you want out of a single video. Longer presets and higher counts are capped by your plan; the app only ever shows you options your plan actually allows.

The number of reels you can request is also naturally limited by how long your source video is — we won't promise more non-overlapping highlights than actually fit.

This applies to auto-detect highlights mode. Switch to sequential mode instead and it's one length only, with the count worked out from the range you pick rather than dialed in directly.

Four tiers, gated by two things:

• Your plan — the free plan is capped at 360p; paid plans can go all the way to 1080p.
• The source video — we never offer a resolution higher than what the original video actually supports, so you don't end up with a false promise of detail that isn't there.

Seven burned-in caption looks, each available in three sizes (small, medium, large):

Text automatically shrinks to fit the frame if a single word is too long to fit at your chosen size — nothing ever runs off the edge of the video.

Two optional, independent extras — neither needs captions turned on:

Header title burns one fixed line of text across the top of every reel from the same session — a series name, a date, whatever you'd otherwise be typing into every caption by hand. It doesn't change per reel.

Number the reels automatically adds "Part 1", "Part 2", and so on, worked out from how many reels the session actually produces — you never type a number yourself. Turn on both and they stack, title on top, part number underneath.

Your own logo is optional, available on every plan, and yours to control — upload an image, choose static bottom-center placement or a DVD-style bouncing animation, and it's sized proportionally to your chosen quality.

The Serlinger Ai mark is separate: a small "Made with Serlinger Ai" watermark in the top-right corner, included automatically on the free plan and not removable there — it's part of what makes the free plan free. Paid plans don't have it. If you also upload your own logo on the free plan, both appear at once, in different corners, so they never overlap.

Auto-detect highlights (the default): when YouTube has computed "most replayed" data for a video, we use it directly — the moments real viewers rewatched most become your reels first.

Most videos — especially smaller channels — don't have this data yet. When it's missing, we fall back to analyzing audio energy across the recording instead: louder, more animated passages score higher. Either way, reel boundaries snap to natural cut points so a reel never starts or ends mid-sentence if we can help it.

Sequential, back-to-back: switch to this if you'd rather cover a specific part of the video in order than let the AI pick moments — choose one reel length, set a start and end point (mm:ss), and reels come out as consecutive, non-overlapping chunks across that range: 0:00–1:00, then 1:00–2:00, then 2:00–3:00, and so on. Useful for a Q&A segment or an announcement block you want covered in full rather than highlighted.

Every reel is cropped to 9:16 portrait and locked onto whoever's speaking or performing — framing holds steady for the whole shot instead of jittering around, and only repositions on an actual camera cut.

Every paid plan drops the Serlinger Ai watermark and gets priority rendering. Lite is capped at 720p and 30s/60s reels only; Standard and up unlock 1080p, all reel lengths, and animated captions with your own logo. Premium and Enterprise add auto-publishing to connected YouTube, TikTok, and Instagram accounts; Enterprise also adds direct video upload.

A "generation" is one full run — pasting a link and hitting Generate — regardless of how many reels come out of it. The free plan gets exactly two, ever. Paid plans get an allowance that resets each billing cycle — weekly for Lite, monthly for every other plan.

Used your allowance early? Buy extra generations any time as credits from the pricing page — they don't expire, however long you hold onto them.

Retention is how long a finished project stays available before it's deleted — 2 hours on Basic, up to 30 days on Enterprise. The countdown runs from when you started the project, not from when it finished — a long render already eats into that window.

You'll get an email the moment your reels are ready, and it says exactly how long you have left to download before that project and its files are deleted for good — so it's worth checking your inbox rather than leaving it for later, especially on the free plan's 2-hour window.

Upgrade or downgrade any time from the pricing page — your current plan is clearly marked there, with the other tiers labeled Upgrade or Downgrade depending on which direction they are.

Cancelling asks you to confirm first. Once confirmed, you keep everything your current plan gives you — full limits, full retention — until the period you already paid for actually ends. Only then do you drop to the free plan. You're never charged again after cancelling, and there's no partial refund for time already paid for.

If a renewal charge can't go through, we don't cut you off immediately — Paystack retries automatically over the following days. You'll see a banner across the app the moment a charge fails, and generating new reels pauses until it's resolved (anything already generated stays exactly as it was). If a retry succeeds, everything resumes with nothing lost. If retries run out, your plan lapses to free.
