Extend's costs scale with pages processed. After 10,000 free credits, Pay As You Go charges $0.0125 per credit, and the Scale plan is a fixed $500 per month. HIPAA coverage needs the Scale add-on or Enterprise, and everything requires developer integration, which non-technical teams may find a barrier.
The catalog has two alternatives, each with a free plan. ChatGPT Plus (consumer) is $20 per user per month. Claude Pro costs the same, $20 per user per month. They are general assistants rather than document-processing APIs, so for ad hoc reading of files they may be enough, but they do not replace a parse and extract pipeline.
"Better suited" below is based on documented features and pricing from our verified profiles, not on a head-to-head test. Prices are USD as published by each vendor.

Taken from the documented limitations in our Extend profile.
| Tool | Starting price | Free tier | Platforms | Main limitation |
|---|---|---|---|---|
| Extend (this page) | $500/mo (Scale) | Yes | Web, API | Costs are per-credit ($0.0125 on Pay As You Go), so spend scales with pages processed and needs developer integration. |
| ChatGPT | $20/mo (Plus (consumer)) | Yes | Web, Desktop, Mobile, API | Almost every tool (uploads, images, voice, deep research, Codex) has plan-dependent usage caps that OpenAI states can change over time, and the API is billed separately from every ChatGPT subscription. |
| Claude | $20/mo (Pro) | Yes | Web, Desktop, Mobile, API | All plans have usage limits that reset on a schedule; the paid chat subscription does not include API access, which is billed separately per token. |
| Alternative | Pick it when | Starting price | Watch out for |
|---|---|---|---|
| ChatGPT General AI chat that can read uploaded documents |
you need ad hoc document questions rather than a production API pipeline | $20/mo (Plus (consumer)) | Not a dedicated parse/extract/split API with citations and evaluation tooling |
| Claude General AI assistant that reads documents and returns structured text |
you want one-off extraction without building a pipeline | $20/mo (Pro) | No built-in document workflows, Studio or evals as in Extend |

ChatGPT and Claude both list a free plan in our catalog. Extend itself includes 10,000 free credits.
ChatGPT Plus (consumer) and Claude Pro are each $20 per user per month.
Per-credit costs that grow with volume, a $500 per month Scale plan, HIPAA only via add-on or Enterprise, and the need for developer integration.
Not necessarily. They are general-purpose assistants, so check whether your workflow needs an API.
