Chatbots · freemium

✓Longest context window of any mainstream assistant — whole repositories, book-length document sets and hour-long video in one pass
✓Free tier runs a current-generation Flash model rather than a downgraded legacy one
✓Spark is the only always-on proactive agent shipping from a major assistant — it surfaces actions instead of waiting to be asked
✓Reads your real Gmail, Drive, Docs and Calendar data, and the same models now sit behind Search AI Mode, Android and Siri
✓One subscription covers reasoning, Deep Research, image generation and Veo/Omni video instead of separate tools

×Model naming is a mess — 3.5 Pro, 3.5 Flash, 3.6 Flash, 3.5 Flash-Lite, Omni, Spark and Flash Cyber are all current, and the app rarely makes clear which one answered
×Headline specs including the 2M-token window and Deep Think circulated through secondhand reporting before Google confirmed them, and the effective-recall charts that would back a multi-million-token claim were not published alongside it
×Long-form prose still trails Claude, and agentic coding trails Claude Code and Codex despite Antigravity 2.0 adding a desktop app and CLI
×An agent with standing access to your inbox and calendar is a much larger trust decision than a chat box, and the best features assume you already live in Google's ecosystem

Chatbots · free

✓Completely free with no paid tier, message meter, ads, or upsell prompts
✓Conversational persona is genuinely distinct — it asks follow-ups and sustains a thread instead of returning bulleted deliverables
✓Voice mode treats long hands-free conversation as the default interaction, not an add-on to a text interface
✓Remembers details across sessions, so returning to an earlier topic works without re-establishing context
✓Runs on Inflection's own models, giving it a consistent voice that prompt-wrapped companion apps struggle to hold

×No web browsing, file uploads, image generation, or code execution — the capability gap against ChatGPT, Gemini, and Claude has widened sharply since 2024
×Little visible feature development since Microsoft hired Mustafa Suleyman and most of Inflection's staff in March 2024 and the company pivoted to enterprise
×No API or developer access for Pi itself; Inflection's model API is sold to enterprises, not to consumer users
×Long-term commitment to the free consumer app is unclear given the parent company's enterprise focus
