Compare strong AI models in one clean workspace.

Promptly gives you one place to run a prompt, inspect every model response, and follow a live synthesis as the answers arrive.

What you get
A cleaner way to review multiple model outputs.

Promptly keeps the run stable while answers stream in, then turns the overlap and disagreement into readable guidance.

Agreement summary

Highlights the core answer when most models align and turns overlap into a usable draft.

Differences that matter

Calls out deeper answers, edge cases, and responses that drift from the pack.

Per-model detail

Keep every raw response, timing, and cost visible without losing the overall picture.

Why teams use it
One place to compare, decide, and move.

Promptly is built for people who need more than a single answer. It helps review overlap, disagreement, and response quality without losing time to tab switching.

Fewer tabs
One prompt, one workspace, one review flow.
Faster review
Watch answers land in parallel instead of waiting on serial checks.
Better judgment
Compare consensus, edge cases, and disagreement before you act.
Workflow

Built for actual decision-making

1
Ask once

Run one prompt across a curated model stack without retyping or tab switching.

2
Watch answers arrive

Responses stream into fixed cards so the workspace stays stable while models finish.

3
Read the synthesis

Promptly builds a rolling summary first, then refines it when the full set is done.

Included in every run
Stable response ordering while models stream in
Rolling synthesis before the full comparison is complete
Per-model timing and cost visibility
Guest mode for instant product testing
Model Guide

What each available model is good at

Use this to decide which lanes to keep active for a run.
GPT-4o
General reasoning

Best for balanced high-quality writing, explanation, and multimodal-style general tasks.

GPT-4o Mini
Fast draft generation

Low-cost default for quick answers, rewrites, and lightweight code help.

Gemini 2.5 Flash
Fast long-context work

Strong for summaries, long prompts, and quick iteration.

Gemini 2.5 Pro
Deep reasoning

Use when quota is available and you want the heavier Gemini reasoning pass.

Claude Sonnet 4
Writing and analysis

Great for polished writing, nuanced analysis, and structured responses.

Claude Opus 4
Premium depth

Best reserved for harder reasoning and higher-stakes review because it is expensive.

Nova Pro
AWS flagship generalist

Strong Bedrock general-purpose model for broad prompt coverage.

Nova Lite
Cheap Bedrock default

Low-cost AWS model for fast testing and broad availability.

Llama 3.2 11B
Open-weight baseline

Useful for comparing an open model against premium hosted models.

Llama 3.2 90B
Large open-weight reasoning

A stronger open-model comparison lane when you want more depth than the 11B variant.

Gemma 3 12B IT
Compact instruction model

Good lightweight comparison lane for clean text tasks and smaller code prompts.

DeepSeek R1
Reasoning-heavy answers

Useful for chain-of-thought-style reasoning and alternative problem solving.

Ministral 3 8B
Efficient text generation

Good cheap text model for concise drafting and instruction following.
