Price terms as published
Each line is the vendor’s own wording, split from the price capture checked on 2026-10-16. Nothing here is rounded, converted or re-worded — the full sentences stay in the review below. Lines that carry only a price continue the plan named on the line above, in the vendor’s own order.
| # | Plan / term | Checked |
|---|---|---|
| 1 | Spira Maxima: Free 50 credits | 2026-10-16 |
| 2 | Creator $15/mo | 2026-10-16 |
| 3 | Growth $59/mo | 2026-10-16 |
| 4 | ngram: Free 600 one-time credits | 2026-10-16 |
| 5 | $29–$299 per month | 2026-10-16 |
One-liner: Both pages sell video by a meter, and the meters are not the same unit. Spira Maxima is the social-video model inside Spira AI — script in, finished vertical post out, presenter and captions included — and it sits at #1 on Product Hunt’s October 2026 monthly leaderboard. ngram builds longer 16:9 explainer video from your own source material (a document, a URL, screenshots, a screen recording) and prices it in credits per generated second. Everything below was read from the two vendors’ own pricing pages on 2026-10-16.
Side by side (both pricing pages re-read 2026-10-16)
| Spira Maxima | ngram | |
|---|---|---|
| Core promise | “The creative agent that makes, posts and grows your channels 24/7” — finished vertical posts, scheduled and published | AI videos for onboarding, training, demos and explainers, from a prompt or a screen recording |
| Free tier | Up to 50 credits, no card; limited trial access to Brand Machine, Influencer Agent and premium models; 20-second output cap | 600 one-time credits ≈ 60 seconds of premium AI footage, watermarked 720p, unlimited manual edits |
| First paid tier | Creator $15/month: 1,200 credits ≈ 800 images or 340 Seedance videos; 60-second videos; 3 Influencer Agents; watermark removed | Basic $29/mo ($23.20/mo billed yearly): 3,000 credits ≈ 300s of premium footage (or 1,000s on the cheaper model), 720p exports |
| Mid tier | Growth $59/mo, or $39/mo billed yearly (“save $240”); most popular tier; 90-second videos; up to 10 Influencer Agents; scheduling and unlimited social account automation | Premium $59/mo ($47.20/mo yearly): 10,000 credits ≈ 1,000s premium (or 3,333s cheaper), 1080p, 1 BrandKit, 1 custom voice and 1 custom avatar |
| Top tier | Enterprise: custom, billed annually — volume discounts, API services, done-for-you service | Ultimate $299/mo ($239.20/mo yearly): 50,000 credits ≈ 5,000s premium (or 16,666s cheaper), 4K, unlimited BrandKits, custom voices, custom avatars and teammates |
| Metering unit | Dollars per second of finished video — $0.09 (FAQ and model scorecard), $0.075 as a launch price on the cost card, “50% off your first month” | Credits per generated second — 10 credits/second premium, 3 credits/second on the cheaper model |
| Output shape | Vertical 9:16 MP4 returned with caption and hashtags | 16:9 video from document, URL, screenshots or screen recording; public link and website embeds on every plan |
| Where it goes after export | Generate posts to TikTok, X and LinkedIn on Creator; scheduling joins on Growth; posting runs through influencer-agent accounts | Public video sharing, embeds, interactive polls/quizzes on the top two tiers |
| Credit rollover | None — subscription credits expire at the end of each cycle | Monthly: one cycle. Annual: until renewal |
| Overflow pricing | Credit packs; a third-party review of the same pages reports packs stay usable six months | Top-up credits at 1,000 for $40 (Free), $20 (Basic), $15 (Premium), $10 (Ultimate) |
| Rating signals | #1 on Product Hunt’s October 2026 monthly leaderboard (621 upvotes, 76 comments when read on 2026-10-16) | 4.6/5 from 62 reviews — badge on its own pricing page, not independently verified |
Two smaller differences worth knowing before you compare headline prices: ngram’s annual view is a flat 20% off every tier, while Spira’s yearly Growth price ($39 against $59) works out to roughly 34% off on the same page that advertises “40% OFF” in its banner. And Spira’s Growth card renders its three credit figures (“2,500 5,000/mo 15,000”) without labels, so the middle number is the one to treat with care until the vendor labels them.
Which is cheaper per second, Spira Maxima or ngram?
This is the question both pages avoid, because they price different units. Here is the arithmetic on the published capacities — treat it as a floor, not a quote:
| Plan | Monthly price | Published capacity | Implied cost per second |
|---|---|---|---|
| Spira Maxima (any paying plan) | $0.09 per second of finished video | — | $0.09 ($0.075 during the launch month) |
| ngram Basic | $29 | 300s premium footage | ~$0.097 |
| ngram Premium | $59 ($47.20 yearly) | 1,000s premium footage | ~$0.059 (~$0.047 yearly) |
| ngram Ultimate | $299 ($239.20 yearly) | 5,000s premium footage |
Read the last column with the meters in mind. ngram’s seconds are generated footage that you then assemble, re-cut and export — an edit that re-renders four scenes spends four scenes’ worth of seconds, and the cheaper 3-credit/second model stretches the same allowance about threefold. Spira’s seconds are finished output: the presenter, motion graphics, captions and music arrive with the generation, and the Generate button prints the exact charge before it runs. A cheaper second that needs an editor and a designer is not automatically the cheaper second that gets published.
What each free tier actually gives you
Neither free tier is a publishing plan, but they fail in opposite directions.
Spira’s 50 free credits are a length cap. Free output stops at 20 seconds with a 400-character script, against 60 seconds on Creator ($15) and 90 seconds on Growth ($59) — and “Remove Watermark” is a listed feature of both paid tiers, so the free tier’s ceiling is a watermark rather than a limit you can work around.
ngram’s 600 credits are a one-time audition. They cover about 60 seconds of premium footage, export watermarked at 720p, and nothing refreshes. The company’s bigger ongoing free offer is elsewhere on the site: a blog-partner programme that turns your posts into branded videos with a public link and embed code. Manual video edits are unlimited even on the free plan, which says something about where ngram thinks the real cost sits — in generation, not in fixing.
Who should pick which
- Pick Spira Maxima if the deliverable is a vertical post for TikTok, X or LinkedIn, and you want the caption, music, pacing and publishing schedule handled in the same place as the generation. The influencer-agent accounts and “unlimited social account automation” on the paid tiers are the product’s actual differentiator against every model that only renders a clip.
- Pick ngram if the source material already exists — a PDF, a product doc, a landing page, a screen recording — and the job is a 16:9 explainer that has to stay current as the product changes. The 20% annual discount and the one-cycle rollover also make it the softer option for lumpy month-to-month workloads.
- Pick neither if you need one video. Both sell a workflow; a single explainer is usually cheaper commissioned, and neither vendor’s free tier produces something you would put your name on.
What we deliberately didn’t test
No account on either platform, no rendered video, no side-by-side quality judgement and no score. Neither page was exercised with the same input, so any claim about which tool produces the better post would be invented. Both prices per second above are the vendors’ own figures; the implied per-second costs for ngram are arithmetic on its published capacities, and the #1 leaderboard position is a third-party read made on 2026-10-16, not a vendor claim. The 4.6/5 review badge is printed by ngram on its own pricing page and has not been verified independently.
