Best AI agents for customer support
The honest shortlist: Intercom Fin, Zendesk AI, Decagon, Sierra and Ada — what each one is, who it fits, and when a custom-built agent beats them all.

Rossum, Instabase, Nanonets, Base64.ai and AWS Textract — what each does, who it fits, and when extraction is only half the job.
Document AI has quietly matured: extraction that used to need a team of OCR engineers is now a platform decision. The catch is that extraction is only the first step — the workflow around it (validation, exceptions, handoff) is where projects actually stall. Here is the shortlist with that caveat baked in.
an AI document-processing platform for extracting data from invoices and other transactional documents.
an AI platform for unlocking data in unstructured documents at scale.
a document-AI platform for data extraction and document workflow automation.
a document-AI platform for extracting data from IDs, forms and documents.
Amazon's managed document OCR and entity-extraction service.
An editorial shortlist ordered by fit for the common case, not a benchmark and not a paid placement. Each entry states what the tool verifiably is and who it broadly fits. We do not publish unverifiable accuracy numbers; if your documents are unusual, run a head-to-head extraction test on your own samples — that is the only number that counts.
Extraction is the easy part; the workflow around it is where projects stall. BuildHaus builds the document agent end-to-end — ingestion, extraction, validation, exception handling and downstream handoff — on Workbench, with a human in the loop for the edge cases. If a platform above already covers your documents, use it. If you need the last mile engineered, that is us.
For invoices and transactional documents, Rossum is the strong default. For high-volume enterprise work, Instabase. For extraction as a raw building block inside AWS, Textract. And when the value is in the workflow around the extraction — validation, exceptions, integration — a platform gets you partway and a custom agent on Workbench gets you the rest.

Clay, Apollo, 11x and Artisan — the honest read on AI outbound, and why the data and the playbook matter more than the agent.
Zapier, n8n, Make and UiPath — where no-code automation wins, and where judgment-heavy back-office work needs a custom agent.
