Crompt AI Chrome Extension vs HeyChat

Crompt AI Chrome Extension and HeyChat are both personal assistants tracked by AIDiveForge. Below is a side-by-side comparison of pricing, capabilities, platforms, and ownership — sourced from each tool's live website and verified before publishing.

Crompt AI Chrome Extension

The platform routes prompts to GPT, Claude, Gemini, and other frontier models from one chat surface, and a side-by-side comparison mode lets you send the same query to multiple models at once so you can judge reasoning differences without re-typing. A Deep Research Agent handles longer investigative queries, surfacing structured summaries rather than raw links. Image generation, a PDF chat tool, and a Chrome extension that overlays the assistant while you browse round out the surface area. The ceiling appears when you need programmatic access — no API is exposed, so any workflow that requires piping Crompt into another system hits a dead end immediately.

HeyChat

HeyChat is an open-source desktop chat client built on Tauri v2, React, and TypeScript. It handles real-time streaming conversations across Google Gemini, OpenAI, Groq, Anthropic, Ollama, and any OpenAI-compatible endpoint, with chat history stored locally in SQLite. The keychain-backed credential storage means your API keys never sit in a dotfile. Where it breaks: this is a chat interface, not a workflow builder — there are no tool calls, no agents running tasks on their own, no branching logic. Teams that need anything beyond a multi-provider chat window will hit that ceiling fast.

Self-hosted option	No	Yes
Platforms	Web, Chrome Extension	Linux, macOS, Windows
Pros	Single-interface access to GPT, Claude, Gemini, and other frontier models, so you stop paying the context-switching cost of maintaining separate accounts and browser sessions for each provider. Side-by-side multi-model comparison screen, which means you can evaluate reasoning quality differences on the same prompt without re-typing or manually juggling tabs. Deep Research Agent for extended, structured investigative queries, so research tasks that would normally require multiple follow-up prompts and manual synthesis get handled in a single run. Chrome extension that operates inline while browsing — summarizing pages, drafting emails, and transcribing videos — so the assistant stays in your flow rather than pulling you out of it. Artifacts feature previews code output alongside the prompt, which means you catch structural errors before running anything instead of debugging blind.	API keys stored in the OS native keychain rather than plain-text files, so a leaked dotfile or accidental repo push does not expose your credentials. Provider-agnostic design covering Google Gemini, OpenAI, Groq, Anthropic, Ollama, and any OpenAI-compatible endpoint, so switching from a cloud model to a local one when costs or privacy requirements shift is a sidebar toggle rather than a reinstall. Local SQLite persistence for chat history, which means your conversation records stay on your machine and are not logged on a vendor's server. Real-time response streaming across all supported providers, so you read output as it generates rather than waiting for a full completion round-trip.
Cons	No API is exposed, so any team that needs to call Crompt from a script, integrate it into a product, or chain it with other services hits an absolute wall — at that point the team migrates to providers like OpenRouter or direct model APIs that expose programmatic access. No self-hosted deployment option exists, which means organizations with data residency requirements or compliance mandates that prohibit sending data to a third-party SaaS cannot use the platform at all — not as a workaround, not with configuration. Credit and subscription usage limits mean heavy research or image-generation workflows start queuing against tier ceilings; teams running high-volume daily usage report needing paid credit top-ups to avoid interruptions, adding cost unpredictability to a tool positioned as a unified alternative to individual model subscriptions.	No tool-use, function calling, or agent loops of any kind — the moment a team needs a model to fetch data, run code, or chain steps without a human typing each prompt, HeyChat offers nothing and teams move to a tool like Open WebUI or a workflow builder that exposes those primitives. No API surface and no programmatic trigger, so the app cannot be embedded in a pipeline, called from a script, or integrated with external automation; teams that need HeyChat's output to feed into another system have no supported path and typically abandon it for a client that exposes an API or plugin interface. A small contributor base and 16-commit history at curation means production bugs may sit unresolved for extended periods, and teams running this in a shared or organizational context carry the maintenance burden themselves under the MIT license.

Bottom line

Crompt AI Chrome Extension is paid while HeyChat is free; HeyChat is open source. Choose based on which difference matters most for your workflow.
