AI CHATBOT BUILDERS WITH FLAT MONTHLY PRICING
Most AI chatbot builders charge per message or per credit. When your bot gets popular, your bill grows. This guide lists every builder that charges a flat monthly fee instead. One price. Every month.
WHY FLAT PRICING MATTERS
Credit-based chatbot pricing creates a perverse incentive: the better your chatbot performs (more conversations, longer interactions), the more you pay. For a small business running an AI chatbot on their website, this means success equals cost uncertainty.
Flat monthly pricing solves this. You know your cost on day one. Your accountant knows the cost. It does not change when traffic spikes during a sale or a holiday weekend.

2. ChatBot (by Text)
$52 – $424/mo · Flat per active chatbot
Visual chatbot builder with rule-based flows and AI assist. Flat pricing per active chatbot, not per message. No source citations.
3. Boei
€0 – €69/mo · Flat per widget

CREDIT-BASED BUILDERS TO WATCH OUT FOR
These popular builders use credit or per-message pricing. They are strong products, but your monthly bill will vary with usage.
- Chatbase — Per-credit pricing. Plans from $19/mo but credits run out faster than expected. Popular but unpredictable costs.
- Botpress — Per AI-spend. Usage-based pricing tied to AI model costs. Advanced but complex to budget.
- Tidio — Per-seat + per-conversation. Three billing dimensions make the real cost 2-3x advertised.
- Botsonic (Writesonic) — Per-message credits. Similar credit model to Chatbase.

FREQUENTLY ASKED QUESTIONS
What does "flat pricing" mean for a chatbot builder?
Flat pricing means you pay a fixed monthly fee regardless of how many messages your chatbot sends. There are no per-message credits, no usage-based charges, and no surprise invoices. Your bill is the same every month.
Why do most chatbot builders use credits instead of flat pricing?
Credit-based pricing lets vendors charge more when you succeed. The more conversations your chatbot handles, the more you pay. This aligns vendor revenue with your usage but makes costs unpredictable for you. Flat pricing trades that upside for cost certainty.
Is there a free AI chatbot builder with no credits?
Yes. AskMeevo offers a free plan with 100 conversations per month and no credit system. Boei and Crisp also offer free tiers with flat usage limits.
Which flat-pricing chatbot builder has source citations?
AskMeevo is the only flat-pricing chatbot builder that includes source citations on every answer. This means your visitors can see exactly which page or document the AI used to generate its response.
Can I switch from Chatbase to a flat-pricing chatbot?
Yes. Most flat-pricing builders including AskMeevo let you add your website URL and documents directly. You cannot import Chatbase data, but setup typically takes 20 minutes or less.
