¿Qué es Frase?
Frase is an herramienta de IA that helps you research, write, and rank content.
It was built in Boston, Massachusetts, back in 2017.
You give it a target keyword and it reads the search results.
Frase pulls the first 20 SERP results into one content brief.
That brief lists all the keywords and headings your competitors share.
A built-in AI writer then drafts sections from that outline.
Multilingual optimization covers English, Spanish, French, German, Italian, Dutch, Portuguese, and Danish.
Here is a walkthrough of how the workspace fits together.
🏆 Ganador: Frase
Frase turns a target keyword into a brief in minutes. Research, outline, and drafting sit in one screen.

Principales ventajas de Frase
Here is what makes Frase worth a look:
- SERP research in minutes: Frase reads the top 20 Google results for your target search query. You get content briefs without opening 20 tabs.
- Topic score for optimized content: A live score shows how your draft compares to top ranking content. It updates as you type.
- Content gap spotting: Compare your own content against rivals on the same keyword. Frase suggests subtopics you skipped.
- Question finder: Search real questions tied to a keyword. Those become subheadings and FAQ blocks.
- Import and improve existing content: Pull in an original article by URL. Frase keeps the formatting and marks the gaps.
- Google Search Console integration: Connect your property and see which pages already earn impressions. Pair that with monthly search volume data to pick fixes.

Our writer signed up for Frase and ran real briefs through it for a client site. Here is what stood out from that hands-on time:
The short version: the research tool earns its keep, the AI writing needs a human pass.
Frase Pros y Contras
✅ Ventajas

- Topic score shows exactly which terms are missing from your draft
- Google Search Console and WordPress integrations on every plan
- Imports existing content and keeps the original formatting intact
❌ Contras

Precios de Paperguide
Paperguide offers four tiers. All paid prices below are billed annually.
| Plan | Precio | Mejor para |
|---|---|---|
| Gratis | $0/mes, facturado anualmente | Casual users testing PDF chat |
| Más | $12 al mes, facturado anualmente. | Students writing a thesis |
| Pro | $24 al mes, facturado anualmente. | Full-time researchers and PhD candidates |
| Empresa | Plan personalizado | Labs and university departments |
Precios verificados en julio de 2026.
Prueba gratuita: Yes. A free plan runs indefinitely, so you can test before paying.
Garantía de devolución de dinero: Not published. The free plan is the intended way to evaluate it.
📌 Nota: Higher tiers add unlimited storage and unlimited references, which matters once a literature review passes a few hundred sources.
⚠️ Advertencia: The headline prices assume annual billing. Month-to-month rates are higher, so check the total before the card goes in.
Principales ventajas de Paperguide
Here is where Paperguide earns its place in a research process:
- Chat with academic papers: Ask a PDF direct questions and get answers with the source passage. This is faster than reading to find one number.
- AI search across real literature: An AI search layer sits on academic databases. It surfaces multiple sources for one question instead of ten blue links.
- Literature review support: The literature review process gets structure, from literature search through to synthesis of complex topics.
- Efficient reference management: Folders, tags, and multi-format imports replace the filing you would do by hand in traditional reference managers.
- Plagiarism checking built in: A plagiarism checker sits next to the editor, which helps keep academic content clean before submission.
- Extensión de Chrome: A Chrome extension gives easy access to the same tools from the browser while you read.
Lo que nuestro equipo observó
Note: we have not had extended hands-on time with Paperguide yet. Everything above and below is drawn from published documentation, the pricing page, and public user reviews. We will add first-hand notes in the future, once our writer completes a full project inside it.
What the documentation does make clear is the shape of the product. It is a research workspace first and a writing assistant second.
Paperguide: Ventajas y desventajas
✅ Ventajas
- Free plan available, so you can test it on real papers first
- Reference manager, citations, and PDF chat live in one workspace
- Pulls from academic databases such as Semantic Scholar
- Plagiarism checker and Chrome extension included
❌ Contras
- No SEO features at all, so it cannot help a blog rank
- Headline pricing requires annual billing to hit the listed rate
- Useless for anyone whose target is search traffic rather than citations
Comparación de características
Below are nine areas where these two AI writing tools split apart, plus a pricing round. The summary table gives you the fast version.
| Característica | Frase | Guía de papel |
|---|---|---|
| Precio inicial | $49/mes | $12/mes |
| Plan gratuito | ❌ | ✅ |
| Search Engine Optimization | ✅ | ❌ |
| Consola de búsqueda de Google | ✅ | ❌ |
| Chat With Uploaded PDFs | ❌ | ✅ |
| Gestor de referencias | ❌ | ✅ |
| Escritor de IA | ✅ | ✅ |
| Detector de plagio | ❌ | ✅ |
| Mejor para | Ranking blog content | Artículos de investigación académica |
1. Escritura y generación de contenido mediante IA
Frase: The AI Article Wizard walks you from keyword to full article in a few clicks. You can also start writing from a blank document and pull AI generated paragraphs in section by section. Output arrives fast, but the actual content usually reads flat until a human rewrites it.
Guía de papel: Full document generation drafts academic writing from sources you have already collected. Because it writes from your uploaded library rather than from the open web, claims stay tied to papers you can check. It is a narrower kind of AI content generation, aimed at accuracy over volume.
⚠️ Advertencia: Neither AI writer produces publish-ready prose. Budget editing time either way.
2. Research Tools
Frase: The question finder is the research tool most people keep coming back to. Type a topic and it returns real queries people ask, which maps neatly to search intent. Those questions become subheadings that help you create high ranking content.
Guía de papel: AI search runs against academic databases instead of Google. One question returns multiple sources with citations attached, which shortens the literature search stage. For anyone comparing options, this is where Paperguide compares favourably against a plain Scholar search.
3. Working With Documents
Frase: Templates cover blog intros, product descriptions, and a meta description generador. Open a new document, pick a template, and the editor fills the frame. Finished drafts export cleanly into WordPress or Google Docs.
Guía de papel: Chat with PDF is the front door here. You upload papers, then ask questions and get answers anchored to specific passages. It can also process papers in bulk and summarise YouTube videos of conference talks.
4. Content Optimization vs Literature Review
Frase: This is the core of the product. The content optimization panel scores your draft against top ranking search results on the same keyword, then lists the terms you are short on. Among content optimization tools at this price, the scoring loop is the reason people stay.
Guía de papel: There is no SEO scoring at all. Instead you get a literature review builder that groups findings across papers and flags where the evidence disagrees. For complex topics, that grouping produces deeper insights than a keyword count ever could.
5. Outlines, Briefs, and Research Reports
Frase: The outline builder assembles headings from competitor structure in about a minute. You can accept the AI generated outline or drag your own together. This is the step that shortens the content creation process most.
Guía de papel: Deep research reports do the equivalent job for scholarship. The system gathers sources, extracts the key points, and returns a structured report you can edit.
The report module also has an extended mode that runs longer and cites more widely, shown below.
6. Datos y análisis
Frase: SEO analytics connect to Google Search Console so you can see which pages already earn impressions. Add the paid SEO layer and you get monthly search volume for keyword research. That combination is how most users decide what to refresh for organic traffic.
Guía de papel: Its data work points inward. The extract data feature reads tables inside PDFs and lifts the numbers into a sheet you can sort. For anyone building a meta-analysis, that alone can save hours per week.
7. Headlines vs Citations
Frase: The blog title generator spits out title ideas around a target search query. It is a small feature, but it removes the blank-page stall at the top of a draft. Useful for any content creator working through a queue.
Guía de papel: Auto-cite papers handles the equivalent friction for academics. Add a source and the citation drops into your chosen style automatically. Over a long thesis, that is the difference between a tidy bibliography and a weekend of cleanup.
8. Drafting Support
Frase: The paragraph generator expands a heading into body copy on demand. It is the fastest route to word count when a content writer is behind schedule. Treat the output as a first pass, not a finished section.
Guía de papel: The AI citation generator works while you draft rather than after. Paste a claim, attach a source, and the reference formats itself. It is a small piece of a broader set of AI powered tools built around the writing process.
9. SERP Analysis vs Plagiarism Checking
Frase: The SERP analyzer breaks down word count, headings, and domain data for every result on page one. It is the closest thing here to a dedicated Herramienta de SEO. If you are weighing Frase against Tablista SEO, this panel is the fair comparison point.
Guía de papel: A free plagiarism checker covers the risk that matters in academia. It scans your draft before submission and flags overlap with published work. There is no SERP data anywhere in the product.
10. Precios y costos
Side by side, the gap is wide. Frase asks for four times the entry price.
| Nivel | Frase | Guía de papel |
|---|---|---|
| Gratis | ❌ No hay versión gratuita | $0/mes, facturado anualmente |
| Entrada | Starter — $49/mo | Plus — $12/per month, billed annually |
| Medio | Professional — $129/mo | Pro — $24/per month, billed annually |
| Arriba | Scale — $299/mo | Enterprise — Custom Plan |
Frase: At $49/mo the Starter tier only makes sense if content drives revenue. Add the SEO layer and unlimited AI writing and you are past $100 a month. For agencies billing clients for search engine optimization, that still clears easily.
Guía de papel: The free plan removes the risk entirely, and $12/per month is inside a alumno budget. Pro at $24/per month adds the storage and reference limits that heavy users need. Nothing here helps you rank, so the low price is not a like-for-like saving.
Diferentes escenarios
| Si lo necesita | Elegir | Por qué |
|---|---|---|
| Presupuesto ajustado | Guía de papel | Free plan, then $12/mo |
| Blog rankings | Frase | Only one with SERP data |
| Thesis or dissertation | Guía de papel | Citations and literature review |
| Trabajo de agencia para clientes | Frase | Briefs at scale |
| Reading dense PDFs | Guía de papel | Chat with any paper |
| Inicio apto para principiantes | Guía de papel | Free tier, less setup |
💰 Tu presupuesto
Frase starts at $49/mo with no free version to test first. Paperguide lets you work for free before spending anything.

🎓 Tu nivel de experiencia

🛟 Team and Support Options

Lo que nuestra reseña no cubrió
We did not test either tool at enterprise scale, and we did not evaluate custom Enterprise pricing on the Paperguide side. Long-run ranking outcomes are outside what any single review can measure, so treat the SEO claims as feature comparisons rather than results. Our notes reflect the July 2026 versions of both products, and both ship changes often.

🏆 GANADOR: FRASE
Frase wins 4 out of 7 categories.
Ideal para: blog teams, SEO agencies, freelance content writers
Frase and Paperguide are not really rivals. One is a set of SEO content tools, the other is an academic workspace.
Frase reads search engines and tells you what SEO content is missing from your draft. That is the whole paso, and it delivers on it.
Paperguide reads journals and tells you what the literature says. For a dissertation, it is the better buy by a wide margin.
Paperguide also wins on price, and its free tier is a real one. If money is the deciding factor, start there.
But if your work is judged by rankings, Frase AI is the only one of the two that can help. Our full Frase review goes deeper on the AI generation quality and where it falls short.
