Pangram vs Smodin (2026): which should you pick?

Pick Pangram if

• Fits if you're a teacher checking whether an essay was written by the student
• Works for editors screening submitted articles before they run

Look elsewhere if

• Skip it if you want help writing, as it only checks what's already written
• Tight if you mark a whole class on the free plan, at about 2,000 words and 3 image scans a day
• Pricey if you scan in bulk through the API, at $0.05 per 100 words once Individual's $10 of monthly API credit runs out
• Watch out: refunds are for individual plans only, within 14 days and with fewer than 20 credits used
• Watch out: Team starts at 2 seats, Professional is billed at sign-up, and zero data retention needs sales-priced Enterprise

Pick Smodin if

• Fits if you want writing, rewriting and plagiarism checks under one login
• Works for students who check essays before submitting

Look elsewhere if

• Skip it if you want to try it first, as no free plan or trial is stated
• Not for you if refunds matter, because every purchase is non-refundable
• Tight if you're on Starter, which limits writing output and leaves out the Chrome extension
• Watch out: using the humanizer can go against school or workplace rules

Pangram

• The free plan stops at 20 credits a day: one credit is 100 words, rounded up, so it covers about 2,000 words. Credits reset daily.
• API use is billed apart from the plans at $0.05 per 100 words, $0.25 per image and $0.05 per second of video; Individual includes $10 of API credit a month, Professional $200.
• Refunds apply only to individual plans, within 14 days of purchase and with fewer than 20 credits used.
• Zero data retention, custom hosting and custom LMS or ATS integrations need the sales-priced Enterprise plan.

Smodin

• The pricing FAQ says all subscription purchases are non-refundable.
• No free plan or trial is stated on the pricing page; both plans are paid.
• Writing output is limited on Starter, and the Chrome extension is Premium only.
• Tools that help text bypass AI detectors may breach school or workplace rules.

Pangram

AI text detection

Scores a text for AI generation and marks AI-written or AI-assisted segments; Pangram benchmarks it against 26 models from OpenAI, Anthropic, Google and others.

AI image and video detection

Checks images of at least 256 x 256 pixels and uploaded videos, frame by frame, for AI generation: 3 image scans a day free, 100 a month on Individual and 500 on Professional.

Similarity checks

Paid plans can run a similarity (plagiarism) check on any scan; each one uses 5 credits, or 500 words of allowance.

Chrome extension and feeds

The Chrome extension checks text in the browser, and on paid plans it automatically scans your feeds on social media, Substack and similar sites.

Docs, Gmail and school systems

Paid plans add Google Docs and Gmail; schools connect it to learning systems such as Canvas, Moodle, Google Classroom and Brightspace.

Developer API

A pay-as-you-go API and an MCP server check text at $0.05 per 100 words and images at $0.25 each, with 20% off bulk text submissions.

Smodin

AI writer and chat

Writes essays, summaries and rewrites from prompts, and a chat assistant answers questions. Premium adds extended chat memory.

AI content detector

Checks whether text is likely AI-generated. The vendor says its detector covers 100 or more languages.

AI humanizer

Rewrites text to read as human-written, with AI Extra and Plagiarism modes. The FAQ calls detection removal about 80% consistent.

Plagiarism checker

Scans text against web and academic sources and reports similarity; Premium runs advanced scans across a whole document.

Rewriter, summarizer and translator

Extra tools for rewording, summarizing and translating text, plus a Chrome extension on Premium for Google Docs and the browser.
