Key Highlights

● Daily active users grew faster than in the prior quarter, reaching roughly 65 million.

● Monthly users and paid subscribers grew more slowly and steadily.

● The Max tier is being retired, with new Super subscribers getting unlimited AI video calls.

● Fourth-quarter gross Margin is guided to about 72% on AI computing costs.

Duolingo (NASDAQ:DUOL) used its third-quarter report on Tuesday evening to make a point that management has been chasing for months: the number of people opening the app every day is growing faster again. The language-learning company said daily active users accelerated from the pace it posted three months earlier, and chief executive Luis von Ahn told stock owners in the quarterly letter that the company is now seeing the user acceleration it had hoped for.

The release was not only about audience size. Revenue and bookings both grew, net Earnings came in at a healthy margin, free Cash Flow stayed strong and the Balance Sheet still carries well over a billion dollars in cash and short-term securities. At the same time, the letter confirmed that the Duolingo Max tier is being retired, that AI video calls are being handed to a much wider group of paying learners, and that the extra computing bill will pull the fourth-quarter gross margin lower.

It is a factual summary of company filings and statements, not a view on the stock.

What did Duolingo actually report for the third quarter?

The headline figures were solid across the board. Total bookings grew at a low double-digit rate, with subscription bookings growing a few points faster than the total. Revenue rose by a similar low double-digit rate to a little over $300 million, and gross margin edged up from a year earlier to roughly the low seventies in percentage terms.

Net earnings for the quarter were positive and equal to a margin in the high single digits. That figure looks very different from the prior-year quarter only because the earlier period contained a one-time tax benefit worth several hundred million dollars, so the year-over-year comparison in the letter is distorted by accounting rather than by operations.

Adjusted EBITDA was lower than a year earlier in dollar terms and as a share of revenue, reflecting the heavier spending on product, computing and Marketing that the company has been openly describing. Operating Cash Flow and free cash flow remained strong, and the free cash flow margin was close to a quarter of revenue.

Why do the daily user numbers matter so much to this story?

For a subscription app built on habit, the daily user count is the leading measure of whether the product is working. Duolingo reported roughly 65 million daily active users, up by close to 30% from a year earlier and clearly faster than the roughly mid-twenties pace of the second quarter. Monthly active users were above 150 million but grew far more slowly, at a low double-digit rate.

The gap between the two measures tells its own story. Daily users are rising faster than monthly users, which means the people already on the platform are showing up more often, and lapsed learners are being reactivated alongside new sign-ups. Management has repeatedly described daily engagement as the engine that later drives subscriptions.

The company also said it expects daily user growth in the fourth quarter to look similar to the third. To keep everyone pointed in the same direction, the company-wide performance Bonus for the quarter is tied to a daily user growth goal, a design choice that signals how strongly management wants audience growth to come first.

How are paid subscribers and bookings moving in comparison?

Paid subscribers reached about 13 million at quarter end, up in the low teens from a year earlier. That is a slower rate than daily users, and it is the reason the letter keeps coming back to conversion, pricing and packaging. Subscription bookings, the largest component of total bookings, grew faster than the total, helped by the way new tiers and family plans are priced.

Chief financial officer Gillian Munson said in the letter that subscription bookings led the acceleration. That framing is deliberate: it tells readers that the faster audience growth has not come at the expense of monetization so far, even though the company has openly said it is willing to trade some near-term monetization for a larger and more engaged base.

Guidance for the final quarter points to bookings and revenue growth in the low teens, with full-year bookings growth slightly lower than full-year revenue growth because of how subscription revenue is recognized over time. Currency is a modest tailwind, which is why growth is a point or so higher on a reported basis than in constant currency.

What is happening to Duolingo Max and the AI video call feature?

The most concrete product decision in the letter concerns Max. The premium tier, which bundled AI-driven conversation practice and explanations, is being sunset. New sales of Max have stopped, and existing individual Max subscribers are being moved to a Super family plan at the same price, so nobody is asked to pay more as a result of the change.

In its place, Video Call, the feature that lets a learner have a spoken conversation with an animated character, is being offered with unlimited access to new Super subscribers. Management expects it to be available to every Super subscriber by the end of the year. In effect, a feature that once justified a higher price is becoming part of the standard paid offering.

The company framed the move as a way to widen the number of learners who experience its most advanced tools. The trade-off, which the letter states plainly, is cost: serving conversation with large language models is far more expensive than serving a pre-written exercise, and that expense shows up in cost of revenue.

Why will gross margin dip in the fourth quarter?

The letter guides gross margin for the fourth quarter to about 72%, below the third-quarter level of nearly 73%. Management attributes the decline to the wider rollout of AI-based features, which raises the computing cost per paying learner even when pricing is unchanged.

The dip is small in absolute terms, but it matters because gross margin has been one of the cleaner positives in the story. Readers following Growth Stocks will notice that this is a recurring pattern for software businesses that fold generative models into a core product: the feature improves engagement and retention, and the unit cost of delivery rises at the same time.

Adjusted EBITDA guidance for the fourth quarter is a little above $80 million, a margin in the mid-twenties, and the full-year margin is guided to roughly the same range. The company is therefore describing a period of steady, not expanding, margins while it builds the audience.

How does the speaking push fit into the product plan?

One of the more quietly important statements in the letter is that the share of exercises a learner can answer by speaking has doubled since the start of the year. Speaking has long been the hardest skill to teach in an app, and the company has been rebuilding exercises so that a learner can talk instead of tapping a screen.

This links directly to the Video Call decision. If more of the course is spoken, then the AI conversation partner is less of an add-on and more of a natural extension of the daily lesson. It also gives the company a stronger answer to the common criticism that app-based learning cannot produce real conversational ability.

The letter repeats the company's mission of building the best education in the world and making it universally available, and mentions an eventual ambition of reaching 1 billion learners. Those are long-dated statements of intent, not guidance, and the filing does not attach a timetable to them.

Which partnerships and marketing moves brought in new learners?

The letter credits two game collaborations, Brawl Stars and Eggy Party, with bringing millions of new and lapsed users to the app. These tie-ins reflect a broader approach in which the brand's playful, character-led marketing is extended into other popular mobile experiences rather than relying only on paid advertising.

A separate in-app event, Junior's Toy Hunt, was described as the first of a planned series of Avatar Collections events. Management plans a regular cadence of such events, which are designed to give users a seasonal reason to open the app and to keep streaks alive.

The company also announced earlier in the year that it had acquired Animade, a motion design studio, a deal posted on its news page in mid-August.

What does the balance sheet look like after the quarter for Duolingo?

Duolingo ended the quarter with roughly $1.4 billion of cash and short-term securities. Operating cash flow was close to $90 million for the quarter and free cash flow was about $75 million, so the Business continues to fund its own growth without outside financing.

That cash position gives management room to keep spending on product, content and computing during a period when it has said it is prioritizing user growth. It also provides flexibility for small acquisitions of the Animade kind, though the letter does not announce any new deal.

For readers comparing the figures with earlier quarters, it is worth separating the cash generation from the headline net earnings. Net earnings in the prior-year quarter were inflated by a tax benefit, whereas cash flow figures are not affected by that accounting item and therefore give a cleaner year-over-year picture.

How does this fit with the company's recent track record?

The stock has had a volatile run over the past year as the market debated whether generative AI would help or hurt a consumer language-learning product, and whether the company could keep growing audience while protecting monetization. The third-quarter letter addresses both questions directly: audience growth is picking up, and monetization is being managed through packaging rather than price increases.

Management has described a deliberate shift in emphasis toward user experience and long-term engagement, and the Max retirement is the most visible sign of it. Rather than reserving the newest AI features for a premium tier, the company is making them part of the main paid plan.

Whether that choice raises conversion over several quarters is something only later reports can show. The current letter offers one data point, a faster daily user trend, and one cost, a lower fourth-quarter gross margin, and leaves the rest to be observed.

What did the company say about how it measures success?

The performance bonus tied to daily user growth is the clearest statement of priorities. By linking pay across the company to a single audience metric, management removes any ambiguity about what is being optimized in the current quarter, and it gives employees a shared goal that is easy to track.

The letter also lists what it counts as learning outcomes, including more spoken practice and richer exercises, and it frames the retirement of Max as a way to give more learners access to those outcomes. These are qualitative claims, and the company does not publish an independent measure of learning gains in the letter.

Readers should note that the figures quoted here come from the company's own presentation and quarterly letter, filed with the Securities and Exchange Commission.

How do the latest figures compare with the previous quarter?

The prior quarterly letter put daily active users at a little under 59 million, so the latest total represents a sizeable sequential jump as well as a faster year-over-year rate. Management had said then that it expected daily growth to stay above 20% through the rest of the year, and the new figure comfortably clears that bar.

That earlier letter credited product changes, marketing and a one-time streak revival in June for the stronger audience trend. The streak revival let millions of learners restore lapsed streaks, and the company also reported a record current-user retention rate. Longer free trials were showing early gains in both revenue and daily users, a detail that helps explain why the company is now comfortable widening access to its AI tools.

Bookings growth in the second quarter had been slower because of a tough comparison with the year before, and the third-quarter rebound in the pace of bookings and subscription bookings is therefore part of a wider normalization. The earlier letter also noted that marketing channels and creative output had roughly tripled over the past year, with influencer content driving a large share of social impressions in markets such as China, Indonesia and India.

Which dated events come next for Duolingo?

The company has already used the third-quarter report to set the baseline for the fourth quarter, so the next scheduled milestone is the report covering the final quarter of the year, which will include full-year results and the first read on how the Max sunset affected conversion and gross margin.

In the meantime, management expects Video Call to reach every Super subscriber by year end, and it plans more Avatar Collections events. Each of those can be checked against the product itself and against any comment on the next call.

Readers who track broader benchmarks, such as the Nasdaq 100, will also see the stock move with sentiment toward consumer software and AI-exposed businesses, which can differ from the company's own results. The facts of the filing remain the anchor for any comparison.
