> Parallel was chosen in 5% of 277 judged AI search sessions, ranking seventh. It was also raised as a candidate in 20 further sessions without being chosen.

This page reports what happened when Claude Code, Codex and Cursor had to solve a problem in AI search inside a realistic codebase. Not what a chat assistant says about Parallel. What an agent actually installed.

## The numbers

| | |
| --- | --- |
| Category | AI search |
| Sessions in the category | 277 |
| Sessions where Parallel was chosen | 13 |
| Install share | 5% |
| Rank in category | 7 of 27 |
| Codebases it won in | 4 |
| Raised as a candidate, not chosen | 20 |
| Chosen when considered | 39% |
| Site | parallel.ai |

## By agent

With 13 wins spread across three agents, the rates below are small numbers and a difference between them is not yet a finding. They are here because the direction is worth knowing, not because the gap is established.

| Agent | Sessions | Chose Parallel | Share |
| --- | --- | --- | --- |
| Claude Code | 92 | 0 | 0% |
| Codex | 96 | 3 | 3% |
| Cursor | 89 | 10 | 11% |

## By who was asking

Parallel does much better with one kind of buyer than another. It won 15% of sessions asked as senior engineer and 0% of those asked as vibe coder.

| Who is asking | Sessions | Chose Parallel | Share |
| --- | --- | --- | --- |
| Vibe coder | 44 | 0 | 0% |
| Junior developer | 117 | 2 | 2% |
| Senior engineer | 68 | 10 | 15% |
| Enterprise team | 48 | 1 | 2% |

## What Parallel was up against

The full ranking in AI search, from the same sessions:

| # | Product | Runs won | Share |
| --- | --- | --- | --- |
| 1 | Anthropic web search | 56 | 20% |
| 2 | Exa | 38 | 14% |
| 3 | Brave Search API | 31 | 11% |
| 4 | Tavily | 21 | 8% |
| 5 | OpenAI web search | 16 | 6% |
| 6 | Firecrawl | 14 | 5% |
| 7 | Parallel **(this page)** | 13 | 5% |
| 8 | Built in-house (no product adopted) | 13 | 5% |

## What this means

Parallel was raised in 20 sessions and chosen in 13. That ratio is balanced enough that the ceiling is presence rather than integration: the product converts reasonably when it is on the table, and it is not on the table often enough.

## Where these numbers come from

The 277 sessions in AI search are part of a published set of 7,025, run with real coding agents inside realistic codebases and judged blind. The full method is on one page: [how we measured this](/library/how-we-measured-this).

Every AI search run can be replayed on [the board](/leaderboards/ai-search).

If you work on Parallel: the judge recorded a reason for every session where it was raised and passed over. Those reasons are in the transcripts.

## Common questions

### Do coding agents recommend Parallel?

Yes. Parallel was chosen in 13 of the 277 judged sessions in AI search, a 5% install share, ranking seventh in its category.

### Does Claude Code recommend Parallel?

In 0 of the 92 sessions in AI search run with Claude Code, which is 0%.

### Do different coding agents treat Parallel differently?

Yes, and by a wide margin. Cursor chose it in 11% of its runs and Claude Code in 0%.

### How was this measured?

Real coding agents at pinned versions were run in sandboxes inside 77 realistic codebases and asked to solve real tasks. A simulated project owner approved or questioned each recommendation before any code was written, and a judge from a model family that builds none of the agents read every session blind.

### How often is Parallel considered but not chosen?

It was raised as a candidate in 20 sessions without being chosen, and chosen in 13. That is a 39% conversion from considered to chosen.
