Auto-recharge is $40 per 1,000 message credits; extra agents cost $25/month and branding removal $99/month. Model choice affects credit use. CustomGPT.ai: Subscription with query, agent, document, word-storage and team-member limits. Standard allows 3 members and 5,000 documents per agent; Premium allows 5 members and 20,000 documents per agent, with auto-sync and branding removal. Confirm capacity upgrades for larger workloads. Ask both vendors to quote the same expected workload, required channels, and implementation scope. Include required subscriptions and usage charges before comparing the total; the listed starting prices alone may cover different work.
The recorded sources for Chatbase include URLs; sitemaps; PDFs; documents; tickets. For CustomGPT.ai, they include websites; documents; PDFs; cloud sources; sitemaps. Ask each vendor to demonstrate ingestion or live access for the exact system you use, with permissions and refresh behavior. A source missing from this directory is not proof that a vendor cannot support it.
Use the same sample of real support requests, approved knowledge, and escalation rules in both pilots. Which source types and sync schedules are supported? Can users inspect citations? How are unanswered questions reviewed? Record answer quality, completed tasks, human handoffs, and total cost in the buyer worksheet. Check these specific cautions before launch: Chatbase: Credits, custom-domain, branding and advanced features can be add-ons; model total cost at volume. CustomGPT.ai: Add-ons and query/document limits can materially change cost; verify exact current plan limits.
