It also breaks down who each ai tool actually serves.
Nuestros redactores dedicaron tiempo a familiarizarse con ambas plataformas.
Esas notas aparecen en las secciones "Lo que nuestro equipo observó" a continuación.
Everything else comes from published specs, documentation, and G2 reviews.
¿Qué es Frase?
Frase is an AI writing asistente built around search engine optimization.
Fue desarrollado en Boston, Massachusetts, en 2017.
You give it a target keyword and it studies the competition.
Frase pulls the top 20 Google results for that same keyword.
From there it builds a content outline and a list of essential terms.
The built-in ai escritor then drafts sections against that plan.
Multilingual optimization covers English, Spanish, French, German, Italian, Dutch, Portuguese, and Danish.
The Frase review video below walks through that workflow start to finish.
🏆 Ganador: Frase
Research, brief, and draft in one place. Nine seo content tools sit behind a single editor. Built for people who publish weekly.
Precios de Frase
Este es el precio de Frase en 2026.
| Plan | Precio | Mejor para |
|---|---|---|
| Motor de arranque | $49/mes | Solo content creator work |
| Profesional | $129/mes | Small teams publishing weekly |
| Escala | $299/mes | Agencies running a heavy seo workflow |
Precios verificados en julio de 2026.
Prueba gratuita: No free version and no trial are offered.
Garantía de devolución de dinero: A 5-day money-back window applies instead of a trial.
📌 Nota: Google Search Console integration and WordPress publishing are included on every plan. The SEO add on costs $35 per month and unlocks deeper keyword research data, including monthly search volume.
⚠️ Pricing conflict: Our research notes list a Basic plan at $14.99, a Team plan at $44.99, and an Enterprise tier at $114.99. Those figures do not match our verified pricing data above, which we treat as canonical. Check the Frase pricing page before you buy, since legacy plans and regional rates both circulate online.
⚠️ Advertencia: Unlimited access to the ai writer is a separate $35 per month add-on. Base plans cap you at roughly 10,000 AI characters monthly, which is only 1,500 to 2,000 words.
Principales ventajas de Frase
Here is what makes Frase worth a look:
- SERP research in minutes: The research tool reads the first 20 results for your target search query. It returns headings, word count targets, and all the keywords rivals share.
- Topic score: A single number shows how your optimized content compares to competitors. It updates live as you write.
- Question finder: Frase surfaces real questions people ask about a topic. That gives you angles that match search intent.
- Works on existing content: You can import an original article and keep its formatting. Frase then suggests fixes rather than a rewrite.
- Short-form templates: Blog title ideas, intros, and a meta description generador sit next to the editor. Handy for the small pieces that eat time.
- Velocidad: Some users report producing content four to five times faster. That gain comes mostly from research, not drafting.
The editor itself keeps research and drafting on one screen.

¿Qué es SciSpace?

You get answers backed by citations, not a bare link list.

Comparación de características
Ready for the detailed comparison of Frase vs SciSpace?
We cover nine features plus cost, so you can see where each asistente de inteligencia artificial earns its keep.
| Característica | Frase | Espacio científico |
|---|---|---|
| Precio inicial | $49/mes | $0 (paid from $8) |
| Plan gratuito | ❌ | ✅ |
| Análisis SERP | ✅ | ❌ |
| Academic Citations | ❌ | ✅ |
| Escritor de IA | ✅ | ✅ |
| Puntuación de contenido | ✅ | ❌ |
| Detector de IA | ❌ | ✅ |
| Consola de búsqueda de Google | ✅ | ❌ |
| Mejor para | Ranking on search engines | Reading and citing papers |
1. Research and Source Analysis
Frase: The research tool reads the first 20 SERP results for your target keyword. It returns headings, questions, and shared terms in one brief. This is the part of Frase AI that most reviewers rate highest.
Espacio científico: Its topic finder searches scientific literature instead of search results. You describe a research question and it surfaces relevant papers with detailed insights attached. The analysis is academic, not competitive.
2. AI Writing and Drafting
Frase: The AI article wizard turns a brief into a full article draft. You can also start writing from a blank document and let it fill gaps. Reviewers say the ai generated content reads generic without edits.
Espacio científico: Its ai writer drafts academic sections from papers you have saved. Output leans formal and sticks close to your sources. It will not help you with creating content for a blog.
💡 Consejo profesional: Treat both AI models as first-draft engines. Paste output into Google Docs, cut the filler, then rebuild the argument in your own words.
3. Content Optimization and Scoring
Frase: A topic score rates your draft against top ranking search results. The number moves as you add missing terms and lift your word count. Few content optimization tools make progress this visible.
Espacio científico: There is no ranking score here at all. The paraphraser adjusts tone and length of a passage instead. That helps clarity in academic writing, not seo optimization.
4. Outlines, Briefs, and Structure
Frase: El esquema constructor copies headings from competitors or drafts new ones. Content briefs land in minutes rather than an afternoon. Every content writer on a deadline feels that difference.
Espacio científico: Its workspace structures the literature review process instead. Teams analyze papers together and share summaries as they go. Live activity tracking adds a to-do checklist for each thesis chapter.
5. Questions and Follow Up
Frase: The question finder pulls real queries people type about a topic. Those questions map neatly to search intent and FAQ blocks. It is a quiet reason Frase produces seo friendly articles.
Espacio científico: Chat with PDF answers questions from a specific paper. You can ask follow up questions until the method makes sense. Each reply carries citations so you can check the source.
6. Citations and Data Sources
Frase: SEO analytics link your own content to live performance data. Google Search Console integration shows which pages already earn organic traffic. There is no academic citation layer at all.
Espacio científico: Its citation generator handles in-text and reference formats across 9,000+ styles. That covers most journals researchers submit to. Turnitin similarity checking sits alongside it for the submissions part of the publishing process.
7. Templates and Short-Form Output
Frase: Templates cover intros, product blurbs, and social copy. Each one opens as a new document so nothing clutters your main draft. For a content creator shipping daily, that ai content generation shortcut adds up.
Espacio científico: The agent gallery offers task-specific agents rather than marketing templates. One agent searches, another drafts, another compares papers. It is a versatile tool, but the focus stays academic.
8. Working With Content You Already Have
Frase: Import a published post and the paragraph generator rewrites weak sections. Original formatting survives the import, so your actual content stays intact. This is the fastest path to refreshed, high ranking content.
Espacio científico: Upload your existing PDF library and pick the data points you want. The data extractor drops them into custom tables for side-by-side reading. It also helps you discover related papers you missed.
9. Quality Checks and Integrations
Frase: The blog title generator tests title ideas before you commit. WordPress publishing and Search Console both connect natively. Missing, though, is any check on whether text reads as ai generated.
Espacio científico: A built-in ai detector scores text before you submit it. A Chrome extension pulls papers straight from journal sites. As a review tool it fits neatly beside other modern tools in a lab.
⚠️ Advertencia: An ai detector score is a signal, not a verdict. Human-written passages get flagged too, so never treat a number as proof either way.
10. Precios y costos
Here are the plans side by side.
| Nivel | Frase | Espacio científico |
|---|---|---|
| Gratis | ❌ Ninguno | Básico: $0 |
| Entrada de pago | Starter: $49/mo | Teams: $8 |
| Medio | Professional: $129/mo | Precio premium: $12 |
| Arriba | Scale: $299/mo | Advanced: $70 |
Frase: You pay a business-tool price for a negocio outcome. Compared with rival seo content tools, for example Surfer SEO and MarketMuse, Frase sits mid-pack rather than cheap. Budget for the $35 add-on if you want unlimited drafting.
Espacio científico: Alumno pricing, student scope. You can test the whole search layer for free before paying anything. Even the top tier costs less per month than Frase’s entry plan.
Diferentes escenarios
| Si lo necesita | Elegir | Por qué |

📝 Tu estilo de escritura

Lo que nuestra reseña no cubrió
This comparison focused on individual writers and small teams. We did not test developer access, API workflows, or institutional licensing at either company. Enterprise contracts and custom rates were also out of scope. Our notes reflect the July 2026 versions, and both ai writing tools ship changes often, so check current plans before you buy.

🏆 GANADOR: FRASE
Frase wins 4 out of 6 categories with a 4.3 rating against 4.2.
Ideal para: blog teams, agency writers, and anyone chasing organic traffic
These two products answer different questions, so the winner depends on your job title. Frase is the herramienta de SEO. It exists to create high ranking content and it does that well.
SciSpace is the research assistant. For a thesis, a systematic review, or a stack of unread PDFs, no content tool from the marketing world comes close.
SciSpace also wins outright on price, and its free tier is genuinely usable. If money is tight and your work is academic, take it and skip the rest of this page.
For everyone publishing to the web, Frase is the better buy. Its research, scoring, and AI generation sit in one editor, and that is where the time savings actually come from.
