How much will the LLM itself cost me?

Typically a few dollars a month, paid directly to your provider at their list price — no markup from us.

What if my key runs out of credit?

Your bot lets you know right away instead of failing silently. You can also add a backup provider key for automatic failover.

What to expect from your 14 days.

You choose your modules and connect your own key. Nothing is deleted — your data is waiting whenever you're ready.
OpenAI, Anthropic (Claude), Google Gemini, GLM, and Kimi (Moonshot) — one primary key plus an optional backup key for automatic failover.
It's encrypted at rest and used only to answer your bot's conversations. Rotate or delete it whenever you want.
Knowledge search (embeddings) always runs on our side and is covered by your modules — only the chat replies themselves use your key.
Add or remove seats any time. Adding seats is billed immediately (prorated); removing seats takes effect at your next renewal.

Start with 14 days. No card, no setup.

Frequently asked

Pricing, plain.

Can't find what you need?

Talk to a human
No. You're on your own API key, so conversations are unlimited — your real limit is your knowledge base size, not message count.
Each module includes a knowledge base size limit. If you're getting close, we'll tell you — you can upgrade the limit any time, nothing shuts off without warning.
Yes. Right now our team handles module and seat changes for you — contact support and we'll update your account with no interruption. Self-serve billing is on the way.
Yes. Every account starts with a 14-day trial — no credit card required. All modules are unlocked using our AI key, so you can fully test the product before connecting your own.
Point Promptly at your website, upload PDFs or Word documents, add manual FAQ entries, or connect a custom JSON API. It indexes everything and re-syncs on the schedule you set. Changes you make to your content are picked up automatically.
Yes, with the Escalation module. When a customer asks for a human — or the bot isn't confident — it escalates to your agent inbox with the full conversation transcript and an AI-generated briefing, so your agent is up to speed before they say hello.
Never on our side — your knowledge base and conversation data stay inside your Promptly account. Since you bring your own AI provider, any training-data terms are governed by your agreement with that provider directly — check their policy for specifics.
No. Once your account is ready, paste one script tag anywhere in your site's HTML and the widget appears. Connecting your knowledge base, customizing colors, and setting up escalation are all done from a point-and-click dashboard — no code, no DevOps.
The bot detects the visitor's language automatically and responds in kind — no extra configuration. It handles 100+ languages fluently, so a French visitor and a Japanese visitor can use the same widget without you lifting a finger.
Completely. You can set your brand colors, upload a logo, choose a widget style (minimalist, modern, or corporate), and edit the opening message — all from the Widget Customizer. Changes show in a live preview before you publish.
