VeoBulk: a Vietnamese $2/month Google Flow batch tool; the extension is just the storefront, and the business runs through Zalo groups

VeoBulk is a Chrome extension that lets you queue dozens of prompts at once in Google Flow to batch-produce Nano Banana images and Veo videos. It launched at the end of May and reached 1,000 users by early October, then stayed flat for a month. The extension itself is no different from hundreds of others. What's worth watching is what's around it: payment methods Vietnamese users are used to, Q&A in Zalo groups, a desktop multi-account pipeline, and a chatbot that returns promo videos from a product link.

Send a TikTok Shop link, get back a promo video

In 2026 Aug 20, VeoBulk's changelog added a line in Vietnamese: "Zalo Video Bot receives a TikTok Shop product link, prepares the content automatically, and sends back a complete video in the chat." The next line reads: "New Zalo users can try one video for free." Three days earlier, the same feature had launched on Telegram first.

Zalo is Vietnam's version of WeChat. The people this bot serves don't want to learn prompts, queues, or concurrency. They list products on TikTok Shop and need dozens of short videos a day. VeoBulk changed "selling a tool" into "handing over the finished video," with the tool kept out of sight in the background.

It's made by Nguyễn Trọng Hòa, with an address listed in Bắc Giang Province, Vietnam. His GitHub previously held Facebook ad tools, Shopee store controls, and cash-on-delivery landing pages for home-goods e-commerce, and a Shopee store under the same name can also be found. He is a tool builder in Vietnam's e-commerce ad scene, not someone building global SaaS.

What it is

The extension (Pro) does what every tool in this category does: queuing, retry on failure, concurrency, and automatic downloads. The Max tier adds a Windows / Mac desktop app, and that's where the real effort goes:

• Several Google accounts run at the same time; when one account's quota runs out, it switches to the next, and each account gets its own proxy;
• Removes the Veo watermark from output images and videos;
• Given a topic, it splits it into shots, generates the video and voiceover (Google TTS and ElevenLabs), then assembles a CapCut draft or exports an MP4 directly;
• In Sep 5 it also added a local MCP, so Claude Desktop, Cursor, and Codex can direct it to produce images and videos.

These features are built for content farms that put out dozens or hundreds of promo videos, try-on videos, and faceless vlogs a day. Ordinary creators don't need them.

How it sells

The top line of the pricing page reads "Pay once, use for the whole period," followed by three points: no auto-renewal; an admin activates your account manually within a few hours; a full refund if you haven't used it within 24 hours. Vietnamese users pay by VietQR bank transfer, and international users pay through PayPal with automatic activation. Every tier gets Q&A in the Zalo and Telegram groups.

Many people in Vietnam don't want to link a card for a subscription, so the Stripe auto-renewal used by English competitors doesn't sell well here. Bank transfer, manual activation, and people replying in a group chat is the familiar process Vietnamese buyers know from Facebook groups for buying software.

Pricing has been dropping too. The June 19 changelog says "Pro from 150k / month," and the pricing page now shows 50k / month. The homepage claims "save up to 30% on long-term plans," but on the pricing page, the 6-month and 12-month prices are exactly the monthly price times the number of months, so there's no visible discount.

Where users come from

• Store keywords: the first half of the store title is the category keyword "Google Flow Automation - Batch Image & Video," with the brand name placed last.
• Bilingual tutorial site: veobulk.com has Vietnamese and English blogs with a dozen-plus long guides on Flow prompts, first/last-frame video, and watermark removal, plus landing pages for keywords like "Google Flow desktop" and "batch video generator." The About page says topics come from Search Console queries.
• Groups and a bot: Zalo and Telegram groups, plus the bot above that lets you try one video free. How big the groups are isn't visible from outside.
• Asking users for reviews: 47 ratings against 1,000 users, a review rate of about 4.7%. The top extension in this category has 240 ratings against 100k users, 0.24%. On Sep 14, two accounts with Pakistani names posted nearly identical reviews on the same day: "The developer is very cooperative, any small issue they communicate and help you solve it." Most of the rest are Vietnamese "ok pro" and "so good" style reviews. It looks like users were asked to review in groups (inference).

For 90 days, nobody on X has mentioned it, TikTok search turns up no videos of it, and no media has covered it. The store's 1,000 also undercounts it: the official site offers a manual zip install, and Max users mostly run the desktop app, so neither group shows up in the store's user count. Paid users and revenue: no number anywhere on the page.

Who it's competing with

Searching "Google Flow / Veo / Whisk automation" by name, the Chrome store has more than thirty extensions with over 1,000 users each, all listed after Sep 1,000, 2025.

It's not early either. Veo 3 was opened to Vietnam back in Jul 3 of 2025 (per VietNamNet: no Ultra needed, AI Pro for one month costs 489,000 VND). VeoBulk launched nearly 11 months late, by which point batch tools and English-language plugins for Vietnam were already being built.

If it were you

C: The sales approach is worth learning; this product isn't worth copying. More than thirty extensions that batch-run Flow already have over a thousand users each, and the leader has 100k. The leaders are also Vietnamese. VeoBulk localized for Vietnam and has only 1,000 users on the store, and it has stalled. The whole category survives by calling Google Flow's internal APIs, automating past CAPTCHAs, and running multiple accounts through proxies. VeoBulk shipped several releases in September, all fixing "Flow login." If Google changes an API or bans a batch of accounts, this whole category stops working together.

Who it suits: people who can build tools and already work in a small-language e-commerce or content niche. What you should learn isn't the features, it's how VeoBulk sold an English red-ocean tool in Vietnam.

Who it doesn't suit: anyone planning another Flow batch extension for the English market. The store's search spots are already held by the early players, and your only difference from them would be the UI.

How to do it:

• Find a small-language market where English tools are already saturated but locals find them hard to buy, such as Thailand, Indonesia, the Philippines, or Turkey;
• Take payment the local way: local bank transfer or e-wallet, one-time payment with no auto-renewal, manual activation, priced where locals see it as a small purchase;
• Keep only a free tier in the extension for lead generation. Put the valuable features (multi-account, watermark removal, automatic video assembly) in a desktop app, outside store review, with payment handled by you;
• Go one step further and build a chatbot where sellers send a product link and get a finished video back, for sellers who don't want to learn tools.

How to get users: create groups in whatever chat app locals use, answer questions there, and have the bot give out one free video; write tutorials in the local language targeting local search terms from day one; ask early users to leave store reviews in the groups, aiming for a rating above 4.5.

When to move: the sooner the better. Launch the week the next video model opens in your target country. VeoBulk was 11 months late and now only has a small slice of the red ocean.

What would show I've got it wrong: (1) VeoBulk or a similar Vietnamese tool publishes revenue figures that are substantial, which would mean this localized model is worth more than it looks and worth copying to other countries; (2) Google builds queues, auto-download, and multi-account support into Flow itself, or begins mass-banning accounts or delisting extensions of this type, in which case the category isn't worth watching; (3) store user numbers start climbing again, which would mean the bot-and-group route is bringing in new traffic and deserves another look.
