Comparison videos · Indian ₹ market · built for creators
Specroll takes your video idea, picks the products, researches what buyers in that city actually care about, builds the storyboard, fills the comparison grid, writes the brief for every part, and generates the clips, stills, voice-over and charts. You download a vertical MP4 and cut your own footage in.

Specroll reads it back before it builds anything
Then six stages
Specs become seconds
Part 1
20s
Must-fix
Part 2
18s
Big deal
Part 3
15s
Nice-to-have
Every key point you keep becomes a part, and its severity sets how long it runs — Must-fix 20s, Big deal 18s, Nice-to-have 15s. Keep all five points a category ships with and the video lands at about 86–89 seconds.
How it works
This isn't a button that spits out a video. It's a studio: Specroll does the research, the grid and the drafting, and you decide what survives each stage.
Theme
Type the idea — or paste your channel URL and pick from three shootable ideas built off your real upload titles. Specroll pulls out the category, the city, the budget and a project title, and shows you what it understood before anything gets built.
Budgets in ₹, k or lakh · snapped to the nearest ₹5,000 · ₹20,000–₹1,20,000
Products
Every product in that category comes up with its photo, brand, model, ₹ price and rating, filterable by type. Tick the ones you're comparing. If the catalog doesn't carry something, paste its URL and an agent with web search researches it into real specs while the row shows its progress.
Photos are stored copies · origin URL and source page kept
Storyboard
4–6 things buyers in that city actually care about, each with a hook, the local proof that the problem is real there, the stakes in ₹ a month or hours, and the mechanism — how it works inside the unit, filmable in cutaway. Tick the points that make the video; tap any row to add your own take.
Header keeps a live count and the running duration
Comparison
For each key point, a matrix across your chosen products — ✓ strong, ~ basic, ✕ missing — with the best product for that point named, and a unique strengths grid pulling out what only one product offers. Every row carries the feature's unit and its source.
3–5 features per point, plus one chart per point
Brief
Per part: a visual plan, a chart-overlay toggle, and the literal video, image, voice-over and chart prompts the models will receive. Change any of them. Pick the model per input. One click copies the full composed prompt if you'd rather run it elsewhere.
Every prompt in the product is inspectable — 11 named groups, per-project overrides, reset to suggested
Create
Each part gets a video tile, an image tile, a voice-over tile, and a chart tile when the overlay is on. Live progress, retry on the ones that fail, preview in place. Then export the whole thing, or download any single asset.

Between stage 1 and stage 2
Specroll doesn't recall products from memory — it reads a live catalog with tools, and turns on web search only where the answer genuinely isn't in the database. It runs one AI call per item rather than one giant call, because the output is better that way, and each call commits its own work, so a failure resumes instead of restarting.

Stage 4, up close
A grid row isn't a vibe. Each feature has a unit and a named source, each product gets a level — full, partial, none or unknown — carrying the measured value, and the chart for that point is drawn from those same numbers. A source that's a retail listing or a BEE rating earns the green ✓. Anything the AI wrote earns an amber ⌁ and says so.
| Feature | Model A | Model B | Model C |
|---|---|---|---|
| BEE star rating ✓ BEE | ✓ | ~ | ✓ |
| Inverter compressor ✓ Amazon.in listing | ✓ | ✓ | ✕ |
| Power draw — W ✓ Amazon.in listing | ✓ | ~ | – |
| Yearly electricity — kWh/yr ✓ BEE | ✓ | ~ | ✕ |
lower is better
“Straight from the listed yearly electricity on each model — no modelling.” The chart note travels with the chart, into the caption on the rendered PNG.

What you actually get
Every part of the video produces real assets you can download one by one, plus one stitched vertical MP4 at the end.
Video
Generated from the prompt you approved, held on the product and the part at work — never on the room.
9:16 · 720×1280 · product-only, no people
Image
A 9:16 PNG for the thumbnail, the cold open, or the cutaway you need on screen while you talk.
9:16 PNG
Audio
The direction is rewritten into an actual narration script first — no stage directions, no timestamps, no camera notes, paced at about 2.5 words a second — then synthesised. Real audio length is measured back onto the asset.
MP3 · duration measured, not estimated
Chart
Rendered server-side straight from the catalog's numbers. Real value printed on every bar, winner in the brand gradient, ₹ grouped the Indian way, chart note as the caption.
1600×900 PNG · no model, no external API
ffmpeg assembles each part's clip and its voice-over in order, looping or trimming every clip to that part's exact length. Charts and stills stay separate downloads — you cut those in yourself, along with your own on-camera footage.
City awareness
Type a different city and the key points, the angles and the storyboard frames change — not the wording, the substance. Specroll profiles the city once, in depth, then every category in that city is written against that profile.
Ten cities are seeded today. Six are Indian; London, Milan, New York and Singapore are also in the table. The city list is fixed — you pick from it, you don't type a new one.
Fields shown are the profile's real structure. The written profile is researched per city.
Where the numbers come from
You're the one whose face is attached to the claim. So the evidence chain is visible the whole way through — and the parts the AI wrote are labelled as the parts the AI wrote.
Retail listings, BEE ratings and hand-checked facts get the green ✓. Anything an AI researched is recorded as unverified on purpose and shows a muted amber ⌁ instead — and that distinction survives all the way into the caption on the finished chart.
“Verified via BEE.”
vs.
“AI-generated from Specroll AI — not independently verified.”
15 spec overrides and 4 price overrides, each naming its source, the source URL, a confidence level and the date it was checked — so a reviewer can re-check the fact instead of trusting it.
A listing for one air conditioner reported “Wattage 5000 W”. That's the unit's cooling output, not what it draws from the wall. Compare running cost on that figure and you overstate it by 4.6×. The checked value from the retail spec sheet is 1082.57 W.
A dollar price may never reach the catalog, and converting one at today's rate is not allowed. A product with no checkable India listing ships with no price at all rather than a made-up one. 33 of the 39 products carry a ₹ price; the other 6 carry none.
Who it's for
If this is you
You already know how to shoot and edit. What kills the schedule is comparing four models on four things that matter, finding numbers you can defend, and turning them into a running order. That part is what Specroll does.
If this is you
Paste your channel URL and Specroll reads the public data — your recent uploads, their views, likes, comments and durations — works out the median views and your real upload cadence, and suggests three shootable ideas grounded in titles you actually published. It carries your tone, humour and recurring formats into every part's brief.
If this is you
You confirm the theme, tick the products, choose the key points, edit the briefs and generate part by part. If you disagree with the storyboard, change it — every prompt in the product is visible and editable, with a reset back to the suggested text.
On the channel read
Specroll states only what it actually fetched. A channel that hides its subscriber count is reported as hidden, never given an invented number, and the idea generator is forbidden from quoting a view count, a CTR or any other statistic. It reads the public Data API — not your Analytics, which lives behind your own login and stays there.
The honest scope
Curated, not crawled. Five categories, thirty-nine products, ten cities — every one of them researched, sourced and priced in ₹.
Real brands — LG, Samsung, Haier, IFB, Blue Star, Lloyd, Voltas Beko, Electrolux, Midea, Bose, Sonos, Sennheiser, Apple, OnePlus, realme, Noise, Boult, Mivi, truke, Soundcore, Philips, Sharp, Candy and more, across 29 brands. Behind them: 68 features, 563 per-product capability cells, 13 charts and 75 storyboard frames. Something missing? Paste its URL and it gets researched in for your project.
Worth knowing before you sign in, so nothing surprises you at stage 6.
Open the studio, type the idea you've been putting off, and watch it turn into products, key points, a grid and a running order you can actually shoot.
