AI tool comparisons, settled

Pick ChatGPT if you want one app for chat, images and voice with the widest plugin ecosystem. Pick Claude if your work is long documents, careful reasoning or production coding. But both are single-vendor and $20/month — TulexAI includes Claude Opus 4.8 and GPT-5.4 side by side (plus Gemini, image, video and voice) for $11/month, so you route each task to the model that’s actually best.

Pick ChatGPT for the most mature app and plugin ecosystem. Pick Gemini if you live in Google Workspace or want Veo video and the largest context window. Both lock you to one vendor at ~$20/month — TulexAI bundles GPT-5.4, Gemini 3.1 Pro and Veo together (plus Claude, Sora, Runway and ElevenLabs) for $11/month.

Pick Claude if your work is reasoning-heavy — long documents, analysis, production code. Pick Gemini for multimodal range, Veo video and Workspace integration. Both are single-vendor at ~$20/month; TulexAI includes Claude Opus 4.8 and Gemini 3.1 Pro together (plus GPT-5, image, video and voice) for $11/month.

Pick ChatGPT if you want one assistant for writing, images, voice and code. Pick Perplexity if your day is research and you need cited, current sources. They’re complementary, not interchangeable — TulexAI includes GPT-5.4 and Perplexity Sonar together (plus Claude, Gemini and media generation) for $11/month, so you stop paying $40 for two single-purpose tools.

Pick Claude for reasoning-heavy work — analysis, long documents, coding. Pick Perplexity when you need current, cited sources fast. They’re complementary; TulexAI includes Claude Opus 4.8 and Perplexity Sonar together (plus GPT-5, Gemini and media generation) for $11/month instead of $40 for two tools.

Pick Gemini if you want a multimodal Google assistant with Veo video and Workspace ties. Pick Perplexity if your work is research that needs current, cited sources. TulexAI includes Gemini 3.1 Pro and Perplexity Sonar together (plus GPT-5, Claude and media generation) for $11/month — the multimodal range and the research engine in one place.

Pick ChatGPT for the most mature app, plugins and multimodal range. Pick Grok if real-time X/web context and a less filtered tone matter most. TulexAI includes Grok 4.1 and GPT-5.4 side by side (plus Claude, Gemini, image, video and voice) for $11/month — less than either alone.

Pick DeepSeek if you want strong, low-cost reasoning and code and don’t need images, voice or a managed app — its chat is free. Pick ChatGPT for a polished, multimodal assistant. TulexAI includes DeepSeek V3.2 and GPT-5.4 together (plus Claude, Gemini, image, video and voice) for $11/month, so you get DeepSeek’s value and frontier multimodal in one place.
