Five alternatives in profile

Sorted by the benchmark base of each one's strongest model (as of August 27, 2026); how Copilot and Perplexity are placed without an index of their own is in the methodology.

01

Claude

When text quality matters: long documents, analysis, concepts and coding. Claude doesn't generate images itself; where it stands in the benchmark today is shown in the row above.

Price: approx. €20 / month (Pro; $17 with annual billing) Free tier: Free (limited usage)

02

Perplexity

When research is your main use case: answers with verifiable sources and live web search, but not a full all-rounder.

Price: approx. €20 / month (Pro) Free tier: Free (limited usage)

03

Microsoft Copilot

When Microsoft 365 is a given: Copilot works in Word, Excel, Outlook and Teams, the contract situation is already settled for many companies, including the EU Data Boundary.

Price: approx. €22 / month (Copilot Pro) Free tier: Free (limited usage)

04

Gemini

When your company lives in Google Workspace: Gemini sits right inside Gmail, Docs and Meet, and Google AI Pro bundles AI with storage at a fair price.

Price: €21.99 / month (Google AI Pro) Free tier: Free (limited usage)

05

Le Chat

When a European provider is a requirement: Mistral is based in France and hosts in the EU, at the lowest entry price in the field, with trade-offs at the model top end.

Price: approx. €15 / month (Pro) Free tier: Free (limited usage)

Benchmark source: Artificial Analysis. Prices per providers (as of July 26, 2026), without guarantee. Copilot (uses OpenAI models) and Perplexity (taps into several third-party models) are listed without an index of their own and placed via their benchmark base, see methodology.

The strongest open-source alternatives to self-host

If data control is your reason for leaving ChatGPT, open weights carry furthest: these models run with a European hosting provider or on your own hardware. The 5 strongest self-hostable models in today's benchmark:

Frequently asked questions

What is the best ChatGPT alternative?

By the independent benchmark, Claude is the strongest alternative today (Claude Opus 5, Intelligence Index 63). The right choice depends on your reason for switching: text quality favours Claude, Google integration Gemini, Microsoft integration Copilot, research Perplexity, EU hosting Le Chat.

Are there free ChatGPT alternatives?

Yes, all five alternatives compared here have free tiers with daily limits. For occasional use that is often enough; for daily work a subscription of roughly €15 to €22 a month is worth it.

Which ChatGPT alternative is GDPR-compliant?

In general, across all providers: a Business or Team plan plus a data processing agreement. EU data residency is offered above all by Microsoft Copilot (EU Data Boundary) and Gemini via Google Workspace; Le Chat comes from a European provider. These details are based on provider information (as of July 26, 2026) and are not legal advice.

What is the best open-source ChatGPT alternative?

GLM-5.3 by Z.ai leads the self-hostable field today (Intelligence Index 60); the full top 5 is in the table on this page and is re-ranked daily. Open-weights models run with a European hosting provider or on your own hardware, which makes them the cleanest answer when data control is your reason for switching.

Which European ChatGPT alternatives are there?

Le Chat by Mistral from France is the only major European end-user product in this field. A second practical route is an open-weights model hosted with a European provider under a data processing agreement. Microsoft Copilot and Gemini offer EU data residency, which settles the data location but keeps a US provider.
