It appeared in January 2023 inside Google Slides, a program where people already work. At that time writing slides from one sentence was new, and users showed it to each other without paid advertising. A blog about presentation topics then brought about 80% of new users from Google search, by the founder's account. Both channels weakened: search traffic fell, and Google added the same function to Slides. The verified total is real, and so is the fall: monthly revenue fell by half between February and July 2026.

It is run by a search marketer. Its pages target what people type into Google. Its best month came from a list article on another company's blog that ranked there. A US$1 trial that needs a card turns visitors directly into subscribers at US$25 a month or US$99 a year.

The first customers came from a lifetime-deal sale on AppSumo, at a time when the product had no AI at all. That gave about a thousand users, word of mouth and a Powered by Guidejar link on every free guide.

It sold a simple promise, a finished PowerPoint file from one sentence, at a low price. In 2024 and the first half of 2025 the archived pricing showed unlimited decks for US$9.99 a month.

By then the plans had moved from unlimited use to slide credits. The founder put the business up for sale.

It put a language model inside Google Sheets from November 2022, and Google's marketplace brought more than 201,000 installs. Few installs paid: US$52,136 of verified revenue in 47 months is about US$0.26 per install. Its most important result may be indirect. A request for a pitch deck for SheetAI led the founder to build MagicSlides. By its own verified data, MagicSlides earned about 14 times as much. SheetAI's own revenue is now falling, and Google has offered a similar AI function inside Sheets since June 2025.

It does the work in the cells instead of explaining what to paste. It works in the Excel that people already have, without a Microsoft Copilot license.

A developer in Bangalore formed a company with an American YouTuber who already had an audience of people who want faceless channels. So customers paid from the first day. Affiliates receive 33% of every payment and brought about a tenth of all revenue, and Meta ads brought more. Nobody could use the product without paying, so no free user consumed paid AI models. Verified revenue reached about US$85,000 a month for six months, and then fell by half.

The team says that people in real meetings do not like a translator that speaks for them. So Deeptrue mainly prompts the user to speak for themselves. It works with any meeting app through a virtual microphone, instead of a bot that joins the call. It rents speech, language and voice models by the minute. So a small team can sell it with metered plans.

The free part does what the market leader charges for: unlimited game reviews, where Chess.com gives free users one a day. Because the engine runs on the player's device, each free review costs Chessigma almost nothing. So the free tool could grow to about 900,000 visitors a month. Revenue started only when the AI coach went on sale in May 2026: TrustMRR shows US$42 in April 2026 and US$3,738 in May 2026.

In divorce, bankruptcy and fraud cases the evidence is often in thousands of pages of PDF statements. The usual answer is a forensic accountant who bills by the hour.

Its founders wrote some of the methods that the industry already used to run models cheaply, such as AWQ for 4-bit weights. They turned that research into a paid serving API.

The owner is an experienced app marketer who already sells more than a dozen other apps from the same developer account.
