ChatFast
Build source-grounded support and research agents from websites, help centers, PDFs, and technical document collections.
About ChatFast
ChatFast builds AI agents from websites, help centers, PDFs, and document collections, then answers with links to the passages it retrieved. It covers two practical jobs. Support agents can handle questions, capture leads, collect structured details, and pass conversation data to other systems through webhooks. Research agents can search papers, reports, and technical documents while keeping citations attached to the answer. A 14-day trial includes one agent, 1,000 credits, and 5 MB of storage. Paid plans start at $35 a month and raise the credit and storage limits. Advanced reasoning, branding removal, and priority email support appear on the $325-a-month Elite plan. Since each message consumes credits, expected chat volume and reasoning mode affect the working cost. The lower storage limits can also be tight for teams with large document sets.
Best for
Best use cases
A visitor asks a policy or product question and needs an immediate answer linked to the exact website page or PDF passage.
A support conversation needs to collect an order number, budget, or issue type before sending the context and transcript through a webhook.
A researcher needs to compare methods or find contradictions across a corpus of papers without opening every document individually.
Compare before choosing
Choose ChatFast when source-linked answers matter more than a general-purpose chatbot that can improvise beyond connected content.
Budget against expected message volume because standard messages consume 10 credits and advanced messages on Elite consume 25 credits.
Compare storage needs carefully: allowances range from 5 MB in the trial to 5 GB on Elite, while Enterprise storage is custom.
Features
Customer support from trusted content
Build an agent from website pages, help-center articles, product documentation, pricing pages, and policies so visitors receive answers linked to the relevant source.
Lead and form capture
Collect contact details, order numbers, budgets, or issue types inside the conversation, then send form data, context, and transcripts to a CRM or help desk through webhooks.
Research and technical analysis
Upload papers, long PDFs, reports, standards, lab notes, or internal knowledge bases and query the collection for claims, methods, comparisons, patterns, and contradictions.
Pros
- Citations link answers to pages or exact passages, which makes support and research output easier to verify.
- Webhook delivery can send captured leads, form fields, context, and transcripts into a CRM or help desk.
- The 14-day trial requires no credit card and provides 1,000 credits for testing a single agent.
Cons
- The trial is temporary rather than a permanent free plan, and paid access starts at $35 per month.
- Credits are consumed per message, so busy support workloads can reach plan limits even when agent count is unlimited.
- Storage is limited to 50 MB on Basic and 500 MB on Premium, which may constrain large PDF or research collections.
