Ranked by evidence — GitHub stars, Hacker News mentions, release activity and how much you can use for free. Recomputed nightly. How the score works.
+ Produces natural, editable prose and follows nuanced instructions over very long documents better than most rivals.
− Pro usage limits can run out mid-session on long conversations, and it has no built-in image generation.
+ The broadest feature set in one place: Deep Research, code-executing data analysis on uploaded spreadsheets, voice mode and a huge library of custom GPTs.
− Free and Plus tiers hit message caps on the best models at busy times, and answers can be confidently wrong without citations unless you ask it to search.
+ Deep Research produces long cited reports from dozens of sources, and it reads your Gmail, Drive and Calendar directly when you allow it.
− Quality swings between Flash and Pro models, and it refuses or hedges on some topics more than competitors.
+ Every answer comes with clickable sources, and Pro lets you switch between frontier models from OpenAI, Anthropic and Google.
− Citations sometimes do not actually support the sentence they are attached to, so you still have to click through for anything important.
+ Completely free and already inside WhatsApp and Instagram, so there is nothing to install or pay for.
− Weaker at reasoning and long documents than paid assistants, cannot be removed from WhatsApp, and is unavailable or limited in some regions.
+ Pulls real-time posts from X into answers, which makes it the fastest way to research breaking news and public sentiment.
− Fewer guardrails and a reliance on X content mean more unverified claims and off-color outputs than other assistants.
+ Works inside the Office apps you already use, drafting Outlook replies, summarizing Teams meetings and turning Word docs into PowerPoint decks.
− Results inside Excel and PowerPoint are often shallow compared with the standalone chat, which makes the $30 business seat hard to justify.
+ Very fast responses and EU-hosted data handling, with a cheaper Pro tier than the US incumbents.
− Smaller model ecosystem and fewer integrations, and answers lag the top US models on hard reasoning tasks.
