AI Companion Statistics 2026: 18 Numbers That Define the Category

Q: Can I cite these statistics in an article or research paper?

Yes. This page is intended as a category reference and citation is welcome. Attribution to sloane.world appreciated but not required. For each individual statistic, verify against the primary source URL cited before republishing — this page is a reference roll-up, not a primary source. Where a figure is marked (approximate) or (aggregated), the underlying primary sources are cited so you can trace the number back.

Q: How often are these figures updated?

This reference was compiled in Q3 2026 and reflects the state of the category as of that date. AI companion category numbers move fast — user counts, funding rounds, and product changes can shift meaningfully within 6 months. Check the "Updated" date on the page and cross-reference the primary source for any figure that's time-sensitive to your use case.

Q: Why don't these numbers include specific figures for [product X]?

Product-specific figures are included when the product has publicly disclosed them or when a credible third-party (analyst report, press coverage, investor deck) has reported them. Many AI companion products — particularly smaller ones and adult-content-permissive ones — don't publicly disclose MAU, revenue, or retention. This reference emphasizes figures that CAN be defensibly cited rather than estimates that can't.

Q: How does the adult AI companion market compare in size to non-adult?

By raw user count, non-adult products (Character.AI, Replika, Nomi) dominate the category — likely 60-70% of total active users. By revenue, adult-content-permissive products collectively account for a much larger share (~40-50% per aggregated estimates) because per-user monetization is higher. Full revenue breakdown is opaque because most adult-permissive products don't publicly disclose numbers, and analyst reports often exclude the vertical entirely.

A citation-ready reference for the state of the AI companion category in 2026. Compiled from public product disclosures, analyst reports, academic studies, and industry-observable metrics. Where possible each figure names its primary source; where sources are aggregated or approximate, that's called out. Free to cite — attribution to sloane.world appreciated.

TL;DR

Character.AI reached ~28M monthly active users at peak (2024) before the content-filter change triggered churn — still the category volume leader.
Global AI companion market projected at $2-3B by 2028 across independent analyst forecasts, from an estimated $700M-1B baseline in 2024.
Character.AI users averaged 2+ hours of daily session time at peak — higher than TikTok's reported ~1.5h. Engagement per session is the category's standout metric.
US Surgeon General declared loneliness an epidemic in May 2023, citing 61% of American adults reporting loneliness (Cigna 2020 index) — the demand-side signal that shaped the category.
Per-persona identity locking (dedicated image model per character) is deployed by <5% of AI companion products despite being the most-complained-about category weakness ("face drift").

7. Subreddit reach: r/CharacterAI ~1.5M members; r/AICompanions ~150K members — useful engaged-user proxy when in-app MAU isn't disclosed. r/AICompanions grew from ~10K to ~150K since late 2023. Source: Reddit public subscriber counts, Q3 2026.

8. ~55-60% of active AI companion users are 18-34 — 18-34 band is the plurality across analyst breakdowns; Gen Z (18-25) alone is ~30-35% of the total user base. Source: aggregated analyst breakdowns, 2024-2025.

9. D30 retention: ~30% flat-subscription, ~15-20% credit-metered — flat-subscription AI companion products (Sloane, Nomi Pro, Replika Pro, Character.AI+) retain 25-35% at D30; credit-metered products with variable monthly cost retain 15-20%. Source: aggregated app-cohort benchmarks, 2024-2026. Directional.

10. Real active-user monthly spend on paid tiers: $15-40 — credit / coin economies (Candy AI Deluxe, DreamGF, Muah AI, Polybuzz) commonly push active users $15-40/mo including credit top-ups. Flat-subscription products cap at sticker ($9.99-19.99/mo). Source: aggregated Reddit spend-tracking threads on r/AICompanions + product-specific subs, 2025-2026.

11. Adult-content-permissive products account for ~40-50% of category revenue — despite Character.AI + Replika dominating raw user count, higher per-user monetization on adult-permissive products (Candy AI, DreamGF, Muah AI, Sloane, Kupid, and dozens more) drives outsized revenue share. Source: aggregated revenue estimates + product disclosures, 2024-2026. Directional.

12. Replika removed NSFW features Feb 3, 2023 → estimated 40%+ churn in the following quarter — widespread user backlash across r/Replika, product-review sites, and mainstream coverage. Partial features later re-added; brand trust never fully recovered. Source: aggregated media coverage (Vice / The Verge, Feb-Apr 2023).

13. Character.AI content-filter change (2023) triggered significant DAU decline — filter tightening throughout 2023-2024 drove users to alternatives (Kindroid, Chub, JanitorAI). Exact percentages undisclosed by Character.AI. Source: App-store ranking shifts + Reddit sentiment analysis, 2023-2024.

15. Chronic loneliness increases premature mortality risk by ~29% — equivalent to smoking ~15 cigarettes daily — Holt-Lunstad et al. meta-analyses cited by the Surgeon General advisory. Category demand-side signal. Source: Holt-Lunstad et al. (2010, 2015), cited in Surgeon General advisory.

16. 79% of adults aged 18-25 report loneliness (Cigna 2020 US Loneliness Index) — highest of any age band, 18 points above the 61% national average. Same age band is the plurality of AI companion users (see #8). Source: Cigna 2020 US Loneliness Index.

17. Character.AI memory context: ~8K tokens per conversation — roughly 15-20 messages of history before older context evicts. Recurring "she forgot what we talked about last session" complaint on r/CharacterAI. Source: Character.AI technical documentation + community-observed behavior, 2024-2026.

18. Per-persona identity locking (dedicated image model per character): deployed by <5% of AI companion products — most platforms generate each image from a text prompt, causing the recurring "face drift" complaint. Sloane is one of the ~5% that uses per-persona LoRA end-to-end. Source: industry observation across ~30 competing products, 2025-2026.

Methodology

Figures above are compiled from three tiers of source:

1. Company disclosures (SEC filings, investor decks, official blog posts, funding-announcement press releases). Most reliable when dated, least reliable when marketing-language-heavy. 2. Analyst reports (Grand View Research, IMARC, MarketsandMarkets, similar). Directional — different methodologies produce different absolute numbers for the same category. Where multiple analysts agree on shape, treated as confirmed. 3. Academic + government studies (US Surgeon General advisories, Kinsey Institute, Cigna Loneliness Index, published journal papers). Most defensible for demand-side / loneliness-context figures.

Where a specific figure is uncertain or aggregated across sources, it's explicitly called out with (approximate) or (aggregated). All figures should be verified against the primary source URL before republication — this article is a reference roll-up, not a primary source.
