Key Findings

  • The TTRPG market expects $5-15/month for AI tools — comparable to VTT subscriptions.
  • Usage-based pricing is poorly received by TTRPG players — they want predictable costs for sessions that can run 3-6 hours.
  • AI Dungeon’s tiered model ($10-30/month with feature gating) is the closest analog.
  • Glyphoxa’s actual costs will be dominated by LLM + TTS — roughly $0.50-3.00 per hour depending on configuration.
  • The community strongly dislikes per-message/per-interaction pricing — it creates anxiety about “using up” interactions during roleplay.
  • A hybrid model (flat subscription + usage cap with overage) is the most viable approach.

TTRPG Community Sentiment on Pricing

Based on Reddit discussions, TTRPG forums, and product reviews:

What Players Accept

  • $5-15/month for a useful AI tool (comparable to D&D Beyond, Roll20 Pro)
  • Flat rate preferred — “I just want to pay and not think about it during the session”
  • Session-based pricing could work: “$1-2 per session” instead of monthly
  • Group/party pricing appreciated: one subscription covers the whole table
  • Free tier is essential for trial and adoption

What Players Reject

  • Per-message/per-interaction pricing — creates anxiety, breaks immersion
  • >$20/month for a single tool (that’s their entire VTT + content budget)
  • Metered usage that could “run out” mid-session — worst possible UX
  • Surprise costs — “I ran a 6-hour session and it cost $15” is unacceptable

DM vs Player Pricing

  • DMs are willing to pay more (~$15-20/month) since they get the most value
  • Players expect $0-5/month additional cost
  • “DM pays, players benefit” is the natural model for TTRPG tools

Recommendations for Glyphoxa

  1. Start with Model A (Tiered Subscription). The TTRPG community expects flat-rate pricing. Gate by quality (model tier, voice quality, NPC count) rather than usage (messages, minutes).

  2. Never charge per-message or per-interaction. This kills immersion and creates the worst possible UX for a roleplay tool. Players should never think “should I talk to this NPC or save my credits?”

  3. Price the “Adventurer” tier at $9/month — this is the sweet spot that matches existing TTRPG tool pricing (D&D Beyond, Roll20 Pro) and covers standard-tier infrastructure costs with margin.

  4. Consider the “DM pays” model. The DM runs Glyphoxa; players just talk to NPCs. Price accordingly — only the DM needs a subscription.

  5. Offer an annual discount (e.g., $9/month or $90/year = 2 months free) to improve retention and cash flow.

  6. The self-hosted option (Model C) should be considered seriously. TTRPG players are technical and privacy-conscious. An open-source core that works with your own API keys, plus a paid hosted version, could drive adoption and community goodwill.

  7. Set hard session caps, not soft ones. “8 sessions/month” is better than “X minutes of audio” — sessions are a natural unit for TTRPG players and are predictable.

  8. Monitor actual usage costs carefully before launch. The cost estimates above are approximations — real-world TTRPG sessions may use more or less LLM/TTS than predicted depending on player interaction patterns.
