Best AI Tools for Parsing Resumes via API (2026)

Affinda correctly tagged the grade unit as "CGPA" but left the numeric Score field empty. The values 8.2 and 8.7 were written plainly in the resumes and never reached the output. The same gap appeared on every input, which confirms a parser limitation rather than a layout problem.

This term appears nowhere in Priya Sharma's resume. Affinda's EMSI taxonomy misclassified a fragment of the TensorFlow Developer Certificate and mapped it to an unrelated industrial certification code — with no confidence flag to warn a downstream system.

Airparser misread the name portion of the email and returned rugged.nichite@email.com instead of rugved.nichite@email.com — a GPT hallucination on a clean, clearly formatted field. Wrong contact information makes the entire parse unreliable for downstream use.

Instead of an array, all 14 skills came back as a single concatenated string. A developer cannot loop over the skills directly — they must split the string by hand first, which defeats the purpose of structured JSON output.

Input 1 returns the name as a top-level field, Input 2 wraps everything in a personal_info block, and Input 3 uses a top-level name plus a separate contact block. All three parse the same data with three different key structures. A production system would work on Inputs 1 and 3 and silently break on Input 2 — no error thrown, just a missing field.

When a resume has no languages section, LlamaParse drops the key entirely instead of returning an empty array. A downstream system expecting that key throws a KeyError — whereas Affinda handles the same case gracefully with an empty array.

Extracta.ai returns only fields defined in the schema upfront. Because LinkedIn was not defined, it was never extracted — on any input — even though it appears clearly in the resumes. Unlike Affinda and Airparser, Extracta.ai will silently skip anything you forget to define.

The messy resume had no languages section, so Extracta.ai returned a single blank entry rather than omitting the field — creating an unexpected null-handling case downstream.

Certifications were only handled correctly on the multi-column resume. On the clean resume, "Python for Data Science and AI — IBM / Coursera" was filed under education instead of certifications; on the messy resume they weren't extracted at all, surfacing instead as the noise skill fragments "udemy 2020" and "aws basics coursera 2022." The field can't be trusted without knowing which input produced it.

Project names, URL fragments, and API names were tagged as skills — "ml apis," "lambda," "s3," "rest apis" on Input 1, and "react dashboard," "ci," "cd," "parse 500" on Input 2. On Input 3, address text bled into a task ("pune did testing and bug fixing"), pulling "Pune" in from the address line.
